The indoor air sucked from theindoor space 71 is heated in theindoor heat exchanger 25 by the flow of the refrigerant. The amount of heat exchange between the refrigerant and the indoor air in theindoor heat exchanger 25 is referred to as heating capacity.

空气温度取得部310取得室内空间71的室温来作为数据。这里，空气温度取得部310取得设置于室内机13的室温检测部41所检测到的室温。The airtemperature acquisition unit 310 acquires the room temperature of theindoor space 71 as data. Here, the airtemperature acquisition unit 310 acquires the room temperature detected by the roomtemperature detection unit 41 provided in theindoor unit 13 .
这里，室温检测部41以预定的周期定期地将包括表示检测到的室温的温度数据在内的信号，经由室内机控制部53和通信线63向室外机控制部51发送。这里，虽然设为从室温检测部41侧定期地发送信号，但也可以是空气温度取得部310根据需要向室温检测部41要求，室温检测部41响应于要求而发送包括温度数据在内的信号。这样，空气温度取得部310从室温检测部41取得室内空间71的室温数据。因此，通过控制部101与通信部104的协作来实现空气温度取得部310。空气温度取得部310作为空气温度取得单元发挥功能。Here, the roomtemperature detection unit 41 periodically transmits a signal including temperature data indicating the detected room temperature to the outdoorunit control unit 51 via the indoorunit control unit 53 and thecommunication line 63 at a predetermined cycle. Here, although the signal is periodically transmitted from the roomtemperature detection unit 41, the airtemperature acquisition unit 310 may request the roomtemperature detection unit 41 as necessary, and the roomtemperature detection unit 41 may transmit a signal including temperature data in response to the request . In this way, the airtemperature acquisition unit 310 acquires room temperature data of theindoor space 71 from the roomtemperature detection unit 41 . Therefore, the airtemperature acquisition unit 310 is realized by the cooperation of thecontrol unit 101 and thecommunication unit 104 . The airtemperature acquisition unit 310 functions as air temperature acquisition means.
表面温度取得部320取得室内空间71的主体的表面温度。室内空间71的主体是指在房屋3中包围室内空间71的墙壁、地板、天花板、柱等构造物。表面温度取得部320取得表面温度检测部43所检测到的表面温度数据来作为室内空间71的主体的表面温度。The surfacetemperature acquisition unit 320 acquires the surface temperature of the main body of theindoor space 71 . The main body of theindoor space 71 refers to structures such as walls, floors, ceilings, and pillars that surround theindoor space 71 in thehouse 3 . The surfacetemperature acquisition unit 320 acquires the surface temperature data detected by the surfacetemperature detection unit 43 as the surface temperature of the main body of theindoor space 71 .
上述的表面温度检测部43以预定的周期定期地将包括检测到的表面温度即主体温度的数据在内的信号经由室内机控制部53和通信线63向室外机控制部51发送。这里，虽然设为从表面温度取得部320侧定期地发送信号，但也可以是表面温度取得部320根据需要向表面温度检测部43发送要求，表面温度检测部43响应于要求而发送包括主体温度数据在内的信号。这样，表面温度取得部320从表面温度检测部43取得表面温度检测部43所检测到的室内空间71的主体温度数据。通过控制部101与通信部104的协作来实现表面温度取得部320。表面温度取得部320作为表面温度取得单元发挥功能。The above-described surfacetemperature detection unit 43 periodically transmits a signal including data of the detected surface temperature, that is, the body temperature, to the outdoorunit control unit 51 via the indoorunit control unit 53 and thecommunication line 63 at a predetermined cycle. Here, it is assumed that the signal is periodically transmitted from the surfacetemperature acquiring unit 320, but the surfacetemperature acquiring unit 320 may transmit a request to the surfacetemperature detecting unit 43 as needed, and the surfacetemperature detecting unit 43 may transmit a request including the main body temperature in response to the request. signal including data. In this way, the surfacetemperature acquisition unit 320 acquires the main body temperature data of theindoor space 71 detected by the surfacetemperature detection unit 43 from the surfacetemperature detection unit 43 . The surfacetemperature acquisition unit 320 is realized by the cooperation of thecontrol unit 101 and thecommunication unit 104 . The surfacetemperature acquisition unit 320 functions as surface temperature acquisition means.
空气调节控制部330控制空气调节部的设备，而控制室内空间71的空气调节。空气调节控制部330经由通信部104与室内机控制部53通信，并与室内机控制部53协作，而使空气调节部进行空气调节。若具体地进行说明，则空气调节控制部330根据运转模式切换四通阀22的流路，调整膨胀阀24的开度，驱动压缩机21、室外送风机31以及室内送风机33。通过控制部101与计时部103及通信部104的协作来实现空气调节控制部330。空气调节控制部330作为空气调节控制单元发挥功能。The air-conditioning control unit 330 controls the equipment of the air-conditioning unit, and controls the air-conditioning of theindoor space 71 . The airconditioning control unit 330 communicates with the indoorunit control unit 53 via thecommunication unit 104, and cooperates with the indoorunit control unit 53 to cause the air conditioning unit to perform air conditioning. Specifically, the airconditioning control unit 330 switches the flow path of the four-way valve 22 according to the operation mode, adjusts the opening degree of theexpansion valve 24, and drives thecompressor 21, theoutdoor blower 31, and theindoor blower 33. The air-conditioning control unit 330 is realized by the cooperation of thecontrol unit 101 , thetimer unit 103 , and thecommunication unit 104 . The air-conditioning control unit 330 functions as an air-conditioning control unit.
空气调节控制部330若基于空气温度取得部310所取得的室温数据判定为室温达到热断开点Toff，则使压缩机21的驱动停止。另外，空气调节控制部330若基于空气温度取得部310所取得的室温数据判定为室温达到热接通点Ton，则使压缩机21的驱动开始。热断开点Toff是为了防止空气调节过度进行而设定的、压缩机21应停止驱动的温度。热接通点Ton是停止了运转的压缩机21应再次开始驱动的温度。以下，将压缩机21的驱动的停止和开始分别称为“热断开(thermo off)”和“热接通(thermo on)”。另外，热断开点Toff和热接通点Ton分别称为“热断开点Toff”和“热接通点Ton”。The airconditioning control unit 330 stops the drive of thecompressor 21 when it is determined that the room temperature has reached the thermal cutoff point Toff based on the room temperature data acquired by the airtemperature acquisition unit 310 . In addition, the air-conditioning control unit 330 starts the drive of thecompressor 21 when it is determined that the room temperature has reached the thermal turn-on point Ton based on the room temperature data acquired by the airtemperature acquisition unit 310 . The thermal cutoff point Toff is a temperature at which thecompressor 21 should stop driving, which is set in order to prevent excessive air conditioning. The hot-on point Ton is the temperature at which thecompressor 21 whose operation has stopped should start driving again. Hereinafter, the stop and start of the drive of thecompressor 21 are referred to as "thermo off" and "thermo on", respectively. In addition, the thermal off point Toff and the thermal on point Ton are referred to as "thermal off point Toff" and "thermal on point Ton", respectively.
室温达到热断开点Toff是指室温从比热断开点Toff低的温度上升至热断开点Toff以上，或者室温从比热断开点Toff高的温度降低至热断开点Toff以下。同样，室温达到热接通点Ton是指室温从比热接通点Ton低的温度上升至热接通点Ton以上，或者室温从比热接通点Ton高的温度降低至热接通点Ton以下。The room temperature reaching the thermal cutoff point Toff means that the room temperature rises from a temperature lower than the thermal cutoff point Toff to a temperature above the thermal cutoff point Toff, or the room temperature decreases from a temperature higher than the thermal cutoff point Toff to below the thermal cutoff point Toff. Likewise, the room temperature reaching the thermal break-in point Ton means that the room temperature rises from a temperature lower than the thermal break-in point Ton to a temperature above the thermal break-in point Ton, or the room temperature decreases from a temperature higher than the thermal break-in point Ton to the thermal break-in point Ton the following.
若更详细地进行说明，则空气调节控制部330若基于空气温度取得部310所取得的室温数据判定为室温达到热断开点Toff并且从使压缩机21的驱动停止起经过了禁止时间，则使压缩机21的驱动开始。To explain in more detail, the air-conditioning control unit 330 determines that the room temperature has reached the thermal cutoff point Toff based on the room temperature data acquired by the airtemperature acquisition unit 310 and the prohibition time has elapsed since the drive of thecompressor 21 was stopped. The drive of thecompressor 21 is started.
这里，禁止时间是指从压缩机21停止驱动起到再次开始驱动为止所需的时间，是以保护压缩机21的目的而设定的时间。在压缩机21的驱动刚停止后，由于制冷循环回路内的压力差大，因此电动机不能旋转。若在这样的状态下要使压缩机21驱动，则导致故障。因此，在压缩机21设定有禁止刚停止驱动后开始运转这一情况的禁止时间。禁止时间例如设定为从数十秒到数分钟的时间。由于规定有这样的禁止时间，因此即使室温达到热接通点Ton，在从压缩机21的驱动停止起到经过禁止时间为止的期间，空气调节控制部330也不开始压缩机21的驱动。因此，根据周围的环境，有时在从压缩机21停止驱动起经过禁止时间到能够重新开始运转为止的期间室温发生变化，而室内空间71的舒适性降低。Here, the prohibition time refers to the time required from the stop of the driving of thecompressor 21 until the driving of thecompressor 21 is restarted, and is set for the purpose of protecting thecompressor 21 . Immediately after the drive of thecompressor 21 is stopped, since the pressure difference in the refrigeration cycle is large, the electric motor cannot be rotated. If thecompressor 21 is driven in such a state, a failure will occur. Therefore, a prohibition time is set in thecompressor 21 for prohibiting the start of operation immediately after the drive is stopped. The prohibition time is set to, for example, several tens of seconds to several minutes. Since the prohibition time is prescribed, the airconditioning control unit 330 does not start the drive of thecompressor 21 until the prohibition time elapses after the drive of thecompressor 21 is stopped, even if the room temperature reaches the heat-on point Ton. Therefore, depending on the surrounding environment, the room temperature may change during the period from when thecompressor 21 stops driving until the prohibition time elapses until the operation can be resumed, thereby reducing the comfort of theindoor space 71 .
另外，这里，如后述的那样，设定部340基于主体温度设定成为热断开点Toff的温度。另外，设定部340与报告部58连接，进行与自然换气的报告有关的处理。通过控制部101实现设定部340。设定部340作为设定单元发挥功能。Here, as will be described later, thesetting unit 340 sets the temperature to be the thermal shutdown point Toff based on the body temperature. In addition, thesetting unit 340 is connected to thereporting unit 58 and performs processing related to the reporting of natural ventilation. Thesetting unit 340 is realized by thecontrol unit 101 . Thesetting unit 340 functions as setting means.
指标取得部350取得除室温检测部41和表面温度检测部43以外的检测部的检测所涉及的数据，来作为预测室内空间71的室温的变化量(以下，称为室温变化量)的指标。若具体地进行说明，则取得来自室外温度检测部42、窗开闭检测部45、日照量检测部47以及人体检测部49的信号所包括的数据。Theindex acquisition unit 350 acquires data related to detection by the detection units other than the roomtemperature detection unit 41 and the surfacetemperature detection unit 43 as an index for predicting the amount of change in room temperature of the indoor space 71 (hereinafter, referred to as the amount of room temperature change). Specifically, the data included in the signals from the outdoortemperature detection unit 42 , the window opening/closing detection unit 45 , the insolationamount detection unit 47 , and the humanbody detection unit 49 are acquired.
＜室温计算的参数＞<Parameters for room temperature calculation>
压缩机21停止驱动后的室温的变化取决于周围的环境。这里，对影响室温的重要因素进行说明。The change in room temperature after thecompressor 21 stops driving depends on the surrounding environment. Here, important factors affecting the room temperature will be described.
图4是表示房屋3中的热移动的情形的图。如图4所示，在室内空间71与室外空间72之间，热经由房屋3的墙壁、窗4、缝隙以及换气设备等而移动。这样的热移动的结果是，室内空间71的室温根据各种因素而变动。概括而言，对于室内空间71的室温，作为室内空间71的主体温度、室内空间71的内部发热、从室外空间72向室内空间71的空气流入热、室内空间71的墙壁和地板的面积以及时间的函数，如(1)式那样设定。FIG. 4 is a diagram showing the state of heat transfer in thehouse 3 . As shown in FIG. 4 , between theindoor space 71 and theoutdoor space 72 , heat moves through the walls of thehouse 3 , thewindows 4 , the gaps, the ventilation equipment, and the like. As a result of such heat transfer, the room temperature of theindoor space 71 varies depending on various factors. In summary, as for the room temperature of theindoor space 71, as the main body temperature of theindoor space 71, the internal heat generation of theindoor space 71, the inflow heat of the air from theoutdoor space 72 to theindoor space 71, the area and time of the walls and floors of theindoor space 71 The function of , is set as formula (1).
室温＝函数(主体温度，内部发热量，空气流入热，墙壁和地板的面积，时间)…(1)room temperature = function (body temperature, internal heat generation, air inflow heat, wall and floor area, time)...(1)
室内空间71的主体温度是室内空间71的墙壁、地板、天花板以及柱等主体的表面温度，如上述的那样，由表面温度检测部43检测，并由表面温度取得部320取得。对于主体温度，作为房屋3的外壁的温度、通过了室内空间71的窗4的日照、室内空间71的隔热性能以及时间的函数，如(2)式那样设定。The main body temperature of theindoor space 71 is the surface temperature of the main body of theindoor space 71 such as walls, floors, ceilings, and columns, and is detected by the surfacetemperature detection unit 43 and acquired by the surfacetemperature acquisition unit 320 as described above. The main body temperature is set as a function of the temperature of the outer wall of thehouse 3 , the sunlight passing through thewindow 4 of theindoor space 71 , the thermal insulation performance of theindoor space 71 , and time, as in the formula (2).
主体温度＝函数(外壁的温度，通过了窗4的日照，隔热性能，时间)…(2)Body temperature = function (temperature of outer wall, sunlight passing throughwindow 4, thermal insulation performance, time)...(2)
外壁的温度是日照、外部空气温度以及时间的函数。换言之，室内空间71的主体经由房屋3的外壁从日照和外部空气受热。另外，室内空间71的主体借助通过了窗4的日照而直接受热。通过了窗4的日照是窗4的性能与窗4的面积的函数。窗4的性能能够根据表示日照从窗4向室内空间71的进入容易度的日照热取得率来估算。这里，作为日照热取得率，能够使用作为日照取得系数的μ值或者作为外皮平均日照取得率的ηA值。室内空间71的隔热性能能够根据表示热传导容易度的热贯流率来估算。作为热贯流率，能够使用作为外皮平均热贯流率的UA值或者作为热损失系数的Q值。The temperature of the outer wall is a function of sunlight, outside air temperature, and time. In other words, the main body of theindoor space 71 is heated from sunlight and outside air via the outer wall of thehouse 3 . In addition, the main body of theindoor space 71 is directly heated by the sunlight passing through thewindow 4 . Insolation throughwindow 4 is a function ofwindow 4 performance andwindow 4 area. The performance of thewindow 4 can be estimated based on the solar heat acquisition rate, which indicates the ease of sunlight entering theindoor space 71 from thewindow 4 . Here, as the solar heat acquisition rate, the μ value as the solar radiation acquisition coefficient or the ηA value as the skin average solar radiation acquisition rate can be used. The thermal insulation performance of theindoor space 71 can be estimated from the heat flow rate, which represents the ease of heat conduction. As the heat transfer rate, the UA value, which is the average heat transfer rate of the skin, or the Q value, which is the heat loss coefficient, can be used.
室内空间71的内部发热量是从存在于室内空间71内部的人、照明、加热器等产生的热量。对于内部发热量，作为处于室内空间71的人的数量亦即室内人数、与来自设置于室内空间71的照明、家电设备以及燃烧器具的各发热量的函数，如(3)式那样设定。The internal heat generation of theindoor space 71 is heat generated from a person, lighting, a heater, and the like existing in theindoor space 71 . The internal calorific value is set as equation (3) as a function of the number of people in theindoor space 71, that is, the number of people in the room, and the calorific value from lighting, home appliances, and combustion appliances installed in theindoor space 71.
内部发热量＝函数(室内人数，照明，家电设备，燃烧器具)…(3)Internal calorific value = function (number of people in the room, lighting, home appliances, burning appliances)...(3)
从室外空间72向室内空间71的空气流入热是经由房屋3的窗4、门、缝隙、换气设备等从室外空间72向室内空间71流入的空气的热。对于空气流入热，作为室外空间72的风量、外部空气温度、与室内空间71邻接的房间的室温以及表示室内空间71的气密性的缝隙相当面积的函数，如(4)式那样设定。这里，缝隙相当面积也称为C值。The air inflow heat from theoutdoor space 72 to theindoor space 71 is the heat of the air flowing in from theoutdoor space 72 to theindoor space 71 via thewindows 4 , doors, gaps, ventilation equipment, and the like of thehouse 3 . The air inflow heat is set as a function of the air volume of theoutdoor space 72 , the outside air temperature, the room temperature of the room adjacent to theindoor space 71 , and the area corresponding to the gap indicating the airtightness of theindoor space 71 . Here, the gap equivalent area is also referred to as the C value.

图5是表示主体温度与室温的关系的一个例子的图。图5表示在制热运转时使压缩机21的驱动停止后的、由主体温度的差异引起的室温的变化的差异。室内空间71的室温虽然受各种参数的影响而变化，但在短期内最受主体温度的影响而变化。在图5中，实线表示室内空间71内的主体温度相对高的情况下的室温的变化。另外，虚线表示室内空间71内的主体温度相对低的情况下的室温的变化。FIG. 5 is a diagram showing an example of the relationship between the main body temperature and the room temperature. FIG. 5 shows the difference in the change in room temperature due to the difference in the main body temperature after the drive of thecompressor 21 is stopped during the heating operation. Although the room temperature of theindoor space 71 is affected by various parameters, it is most affected by the temperature of the main body in a short period of time. In FIG. 5 , the solid line indicates a change in room temperature when the temperature of the main body in theindoor space 71 is relatively high. In addition, the dotted line represents a change in room temperature when the temperature of the main body in theindoor space 71 is relatively low.
如图5所示，在主体温度相对低的情况下，与主体温度相对高的情况相比，上升至热断开点Toff而压缩机21停止驱动后的室温大幅度地降低。这是因为，在制热运转时，刚热断开后的室温迅速地降低至与主体温度相同的程度，其后，以与主体温度相同的程度缓慢地降低。因此，如图5所示，若假设为在相同的热断开点Toff停止了压缩机21的驱动，则在主体温度相对低的情况下，与主体温度相对高的情况相比，室温在正经过禁止时间time0的期间越过热接通点Ton变化的可能性变高。若室温越过热接通点Ton变化，则在制热时变得过冷，在制冷时变得过热。因此，室内空间71的舒适性降低。As shown in FIG. 5 , when the main body temperature is relatively low, the room temperature after thecompressor 21 stops driving after the temperature rises to the thermal cutoff point Toff is greatly reduced compared to when the main body temperature is relatively high. This is because, during the heating operation, the room temperature immediately after the thermal cutoff is rapidly lowered to the same extent as the main body temperature, and thereafter, it is gradually lowered to the same extent as the main body temperature. Therefore, as shown in FIG. 5 , if it is assumed that the drive of thecompressor 21 is stopped at the same thermal cutoff point Toff, when the temperature of the main body is relatively low, the room temperature is higher than that in the case where the temperature of the main body is relatively high. During the elapse of the prohibition time time0, there is a high possibility that the thermal turn-on point Ton is changed. When the room temperature changes beyond the thermal switch-on point Ton, it becomes supercooled during heating and overheated during cooling. Therefore, the comfort of theindoor space 71 decreases.
这样，为了抑制室温在正经过禁止时间time0的期间越过热接通点Ton变化，而图3所示的设定部340根据主体温度设定不同的热断开点Toff。若具体地进行说明，则设定部340基于表面温度取得部320所取得的主体温度，在主体温度低时将热断开点Toff设定为高的温度。换言之，在主体温度是第1温度的情况下，设定部340将热断开点Toff设定为比主体温度为比第1温度高的第2温度的情况高的温度。In this way, in order to prevent the room temperature from changing beyond the thermal ON point Ton while the prohibition time time0 is elapsed, thesetting unit 340 shown in FIG. 3 sets different thermal OFF points Toff according to the main body temperature. Specifically, thesetting unit 340 sets the thermal shutdown point Toff to a high temperature when the body temperature is low, based on the body temperature acquired by the surfacetemperature acquisition unit 320 . In other words, when the body temperature is the first temperature, thesetting unit 340 sets the thermal shutdown point Toff to a higher temperature than when the body temperature is the second temperature higher than the first temperature.
若更详细地进行说明，则设定部340基于表面温度取得部320所取得的主体温度预测从压缩机21停止驱动起到压缩机21重新开始驱动为止所需的禁止时间经过为止的室温变化量。一般来说，室温与主体温度之差越大，禁止时间内的室温变化量越大。例如在制热运转时，主体温度越低，室温变化量越大，在制冷运转时，主体温度越高，室温变化量越大。To explain in more detail, thesetting unit 340 predicts the amount of room temperature change until the prohibition time required until thecompressor 21 stops driving until thecompressor 21 restarts driving elapses, based on the body temperature acquired by the surfacetemperature acquiring unit 320 . . In general, the larger the difference between the room temperature and the main body temperature, the larger the amount of room temperature change within the forbidden time. For example, during the heating operation, the lower the main body temperature, the larger the room temperature change amount, and during the cooling operation, the higher the main body temperature, the larger the room temperature change amount.
设定部340使用上述(1)式来预测从压缩机21停止驱动起到经过禁止时间为止的室温变化量。如上述的(1)式那样，通过包括主体温度和时间在内的多个参数来确定室温。这里，上述的(1)式所包括的发热、空气流入热以及墙壁和地板的面积的参数，可以使用预先规定的值，也可以使用传感器的检测所涉及的值。Thesetting unit 340 predicts the amount of room temperature change from the time when thecompressor 21 stops driving until the prohibition time elapses, using the above-mentioned formula (1). As in the above-mentioned formula (1), the room temperature is determined by a plurality of parameters including the main body temperature and time. Here, the parameters of heat generation, air inflow heat, and area of walls and floors included in the above-mentioned formula (1) may use predetermined values, or may use values related to detection by sensors.
设定部340预测禁止时间内的室温变化量，并基于预测到的变化量设定热断开点Toff。若具体地进行说明，则设定部340将热断开点Toff设定为，在作为设定温度的热接通点Ton上加上或者减去预测到的变化量而得的温度。在制热运转时，设定部340将热断开点Toff设定为在热接通点Ton上加上预测到的室温变化量而得的温度。由此，室温在热断开后的禁止时间结束的时刻降低至热接通点Ton。与此相对地，在制冷运转时，设定部340将热断开点Toff设定为在热接通点Ton上减去预测到的室温变化量而得的温度。由此，室温在热断开后的禁止时间结束的时刻上升至热接通点Ton。Thesetting unit 340 predicts the amount of room temperature change within the prohibited time period, and sets the thermal cutoff point Toff based on the predicted amount of change. Specifically, thesetting unit 340 sets the thermal off point Toff to a temperature obtained by adding or subtracting the predicted amount of change from the thermal on point Ton, which is the set temperature. During the heating operation, thesetting unit 340 sets the thermal off point Toff to a temperature obtained by adding the predicted change in room temperature to the thermal on point Ton. Thereby, the room temperature is lowered to the thermal on point Ton at the time when the prohibition time after thermal off ends. On the other hand, during the cooling operation, thesetting unit 340 sets the thermal off point Toff to a temperature obtained by subtracting the predicted change in room temperature from the thermal on point Ton. Thereby, the room temperature rises to the thermal on point Ton at the time when the prohibition time after thermal off ends.
图6是表示制热运转时的主体温度与室温的关系的一个例子的图。另外，图7是表示制冷运转时的主体温度与室温的关系的一个例子的图。空气调节控制部330按照由设定部340设定的热断开点Toff使压缩机21的驱动停止。在图6和图7中，虚线表示室内空间71内的主体温度相对低的情况、具体而言主体温度为第1温度的情况下的室温的变化。与此相对地，实线表示室内空间71内的主体温度相对高的情况、具体而言主体温度为比第1温度高的第2温度的情况下的室温的变化。FIG. 6 is a diagram showing an example of the relationship between the main body temperature and the room temperature during the heating operation. In addition, FIG. 7 is a diagram showing an example of the relationship between the main body temperature and the room temperature during the cooling operation. The air-conditioning control unit 330 stops the drive of thecompressor 21 according to the thermal cutoff point Toff set by thesetting unit 340 . In FIGS. 6 and 7 , the dotted lines indicate changes in room temperature when the body temperature in theindoor space 71 is relatively low, specifically, when the body temperature is the first temperature. On the other hand, the solid line shows a change in room temperature when the main body temperature in theindoor space 71 is relatively high, specifically, when the main body temperature is a second temperature higher than the first temperature.
如图6所示，在制热运转时，设定部340将热断开点Toff1和热断开点Toff2设定为比热接通点Ton高的温度。并且，设定部340将主体温度相对低的情况下的热断开点Toff1设定为比主体温度相对高的情况下的热断开点Toff2高的温度。若在主体温度相对低的情况下室温上升至热断开点Toff1，则空气调节控制部330使压缩机21的驱动停止而进行热断开。另外，在主体温度相对高的情况下，若室温上升至比热断开点Toff1低的热断开点Toff2，则空气调节控制部330使压缩机21的驱动停止而进行热断开。这里，以下，也存在将热断开点Toff1和热断开点Toff2分别称为第1驱动停止温度和第2驱动停止温度的情况。As shown in FIG. 6 , during the heating operation, thesetting unit 340 sets the thermal off point Toff1 and the thermal off point Toff2 to a higher temperature than the thermal on point Ton. Then, thesetting unit 340 sets the thermal cutoff point Toff1 when the body temperature is relatively low to a higher temperature than the thermal cutoff point Toff2 when the body temperature is relatively high. When the room temperature rises to the thermal cutoff point Toff1 when the body temperature is relatively low, the air-conditioning control unit 330 stops the drive of thecompressor 21 to perform thermal cutoff. In addition, when the main body temperature is relatively high, when the room temperature rises to the thermal cutoff point Toff2 lower than the thermal cutoff point Toff1 , the airconditioning control unit 330 stops the drive of thecompressor 21 and performs thermal cutoff. Hereinafter, the thermal-off point Toff1 and the thermal-off point Toff2 may be referred to as a first drive stop temperature and a second drive stop temperature, respectively.
在热断开后，主体温度越低，室温越大幅度地降低。此时，预测禁止时间time0内的室温变化量来设定热断开点Toff1和热断开点Toff2。因此，室温在禁止时间time0结束的时刻降低至作为设定温度的热接通点Ton。若室温降低至热接通点Ton，则空气调节控制部330使压缩机21的驱动开始而进行热接通。由此，室温再次开始上升。这样，与主体温度的高低无关地将室温保持于设定温度以上的温度。After thermal disconnection, the lower the body temperature, the greater the reduction in room temperature. At this time, the thermal off point Toff1 and the thermal off point Toff2 are set by predicting the amount of room temperature change within the prohibition time time0. Therefore, the room temperature is lowered to the thermal on point Ton, which is the set temperature, at the end of the prohibition time time0. When the room temperature falls to the thermal turn-on point Ton, the air-conditioning control unit 330 starts the drive of thecompressor 21 to perform thermal turn-on. Thereby, the room temperature starts to rise again. In this way, the room temperature is maintained at a temperature equal to or higher than the set temperature regardless of the temperature of the main body.
与此相对地，在制冷运转时，如图7所示，设定部340将热断开点Toff1和热断开点Toff2设定为比热接通点Ton低的温度。并且，设定部340将主体温度相对低的情况下的热断开点Toff1设定为比主体温度相对高的情况下的热断开点Toff2高的温度。若在主体温度相对低的情况下室温降低至热断开点Toff1，则空气调节控制部330使压缩机21的驱动停止而进行热断开。另外，若在主体温度相对高的情况下室温降低至比热断开点Toff1低的热断开点Toff2，则空气调节控制部330使压缩机21的驱动停止而进行热断开。On the other hand, during the cooling operation, as shown in FIG. 7 , thesetting unit 340 sets the thermal off point Toff1 and the thermal off point Toff2 to a temperature lower than the thermal on point Ton. Then, thesetting unit 340 sets the thermal cutoff point Toff1 when the body temperature is relatively low to a higher temperature than the thermal cutoff point Toff2 when the body temperature is relatively high. When the room temperature falls to the thermal cutoff point Toff1 when the body temperature is relatively low, the airconditioning control unit 330 stops the drive of thecompressor 21 to perform thermal cutoff. In addition, when the room temperature falls to the thermal cutoff point Toff2 lower than the thermal cutoff point Toff1 when the body temperature is relatively high, the airconditioning control unit 330 stops the drive of thecompressor 21 and performs thermal cutoff.
在热断开后，主体温度越高，室温越大幅度地上升。此时，预测禁止时间time0内的室温变化量来设定热断开点Toff1和热断开点Toff2。因此，室温在禁止时间结束的时刻上升至作为设定温度的热接通点Ton。若室温上升至热接通点Ton，则空气调节控制部330使压缩机21的驱动开始而进行热接通。由此，室温再次开始降低。这样，与主体温度的高低无关地将室温保持于设定温度以下的温度。After thermal disconnection, the higher the body temperature, the greater the room temperature rise. At this time, the thermal off point Toff1 and the thermal off point Toff2 are set by predicting the amount of room temperature change within the prohibition time time0. Therefore, the room temperature rises to the thermal on point Ton, which is the set temperature, when the prohibition time expires. When the room temperature rises to the thermal turn-on point Ton, the air-conditioning control unit 330 starts the drive of thecompressor 21 to perform thermal turn-on. Thereby, the room temperature starts to decrease again. In this way, the room temperature is maintained at a temperature equal to or lower than the set temperature regardless of the temperature of the main body.
图8是表示实施方式1所涉及的空调装置1所进行的空气调节控制处理的流程的图。空调装置1的控制部101在空调装置1对室内空间71进行制热或者制冷时执行图8所示的空气调节控制处理。FIG. 8 is a diagram showing a flow of air-conditioning control processing performed by the air-conditioning apparatus 1 according to Embodiment 1. FIG. Thecontrol unit 101 of the air conditioner 1 executes the air conditioning control process shown in FIG. 8 when the air conditioner 1 heats or cools theindoor space 71 .
在图8所示的空气调节控制处理中，控制部101首先基于由表面温度检测部43检测到的主体温度，预测热断开后的禁止时间内的室温变化量(步骤S1)。禁止时间是为了保护压缩机21而以不在刚热断开后再次启动压缩机21的方式规定的时间。在停止了压缩机21的驱动的情况下，控制部101预测在禁止时间内室温变化了何种程度。若具体地进行说明，则控制部101在空调装置1的制热运转时预测为主体温度越低室温变化量越大，在制冷时则预测为主体温度越高室温变化量越大。In the air-conditioning control process shown in FIG. 8 , thecontrol unit 101 first predicts the amount of room temperature change within the prohibition time after thermal shutdown based on the body temperature detected by the surface temperature detection unit 43 (step S1 ). The prohibition time is a time predetermined so as not to restart thecompressor 21 immediately after thermal shutdown in order to protect thecompressor 21 . When the drive of thecompressor 21 is stopped, thecontrol unit 101 predicts how much the room temperature has changed within the prohibition time. Specifically, thecontrol unit 101 predicts that the lower the body temperature during the heating operation of the air conditioner 1, the larger the room temperature change, and during cooling, the higher the body temperature, the larger the room temperature change.
若预测禁止时间内的室温变化量，则控制部101根据预测到的室温变化量调整热断开点Toff(步骤S2)。若具体地进行说明，则控制部101在制热运转时将热断开点Toff设定为在热接通点Ton上加上预测到的室温变化量而得的温度。另外，控制部101在制冷运转时将热断开点Toff设定为在热接通点Ton上减去预测到的室温变化量而得的温度。在步骤S1和步骤S2中，控制部101作为设定部340发挥功能。When the amount of change in room temperature within the prohibited time period is predicted, thecontrol unit 101 adjusts the thermal shutdown point Toff based on the predicted amount of change in room temperature (step S2 ). Specifically, thecontrol unit 101 sets the thermal off point Toff to a temperature obtained by adding the predicted change in room temperature to the thermal on point Ton during the heating operation. In addition, thecontrol unit 101 sets the thermal OFF point Toff to a temperature obtained by subtracting the predicted change in room temperature from the thermal ON point Ton during the cooling operation. In step S1 and step S2 , thecontrol unit 101 functions as thesetting unit 340 .
若调整热断开点Toff，则控制部101参照由室温检测部41检测到的室温，来判定室温是否达到热断开点Toff(步骤S3)。若具体地进行说明，则在制热时，在室温上升至热断开点Toff以上的温度的情况下，控制部101判定为室温达到了热断开点Toff。与此相对地，在制冷时，在室温降低至热断开点Toff以下的温度的情况下，控制部101判定为室温达到了热断开点Toff。When the thermal cutoff point Toff is adjusted, thecontrol unit 101 refers to the room temperature detected by the roomtemperature detection unit 41 to determine whether or not the room temperature has reached the thermal cutoff point Toff (step S3 ). Specifically, when the room temperature rises to a temperature equal to or higher than the thermal cutoff point Toff during heating, thecontrol unit 101 determines that the room temperature has reached the thermal cutoff point Toff. On the other hand, when the room temperature is lowered to a temperature equal to or lower than the thermal cutoff point Toff during cooling, thecontrol unit 101 determines that the room temperature has reached the thermal cutoff point Toff.
在判定为室温未达到热断开点Toff的情况下(步骤S3：否)，控制部101停留在步骤S3，待机至室温达到热断开点Toff为止。When it is determined that the room temperature has not reached the thermal cutoff point Toff (step S3 : NO), thecontrol unit 101 remains in step S3 and waits until the room temperature reaches the thermal cutoff point Toff.
与此相对地，在判定为室温达到了热断开点Toff的情况下(步骤S3：是)，控制部101实施空气调节部的热断开(步骤S4)。若具体地进行说明，则控制部101控制压缩机21来将转速变更为0，由此使压缩机21的驱动停止。由此，空调装置1对室内空间71的空气调节停止。On the other hand, when it is determined that the room temperature has reached the thermal cutoff point Toff (step S3: YES), thecontrol unit 101 performs thermal cutoff of the air conditioning unit (step S4). Specifically, thecontrol unit 101 controls thecompressor 21 to change the rotational speed to 0, thereby stopping the drive of thecompressor 21 . Thereby, the air conditioning of theindoor space 71 by the air conditioner 1 is stopped.
若空气调节部进行热断开，则控制部101参照由室温检测部41检测到的室温，来判定室温是否达到了热接通点Ton(步骤S5)。若具体地进行说明，则在制热时，在室温降低至热接通点Ton以下的温度的情况下，控制部101判定为室温达到了热接通点Ton。与此相对地，在制冷时，在室温上升至热接通点Ton以上的温度的情况下，控制部101判定为室温达到了热接通点Ton。When the air conditioning unit is thermally OFF, thecontrol unit 101 refers to the room temperature detected by the roomtemperature detection unit 41 to determine whether or not the room temperature has reached the thermal ON point Ton (step S5 ). Specifically, thecontrol unit 101 determines that the room temperature has reached the thermal switch point Ton when the room temperature is lowered to a temperature lower than the thermal switch point Ton during heating. On the other hand, when the room temperature rises to a temperature equal to or higher than the thermal switch point Ton during cooling, thecontrol unit 101 determines that the room temperature has reached the thermal switch point Ton.
在室温未达到热接通点Ton的情况下(步骤S5：否)，控制部101停留在步骤S5，待机至室温达到热接通点Ton为止。When the room temperature has not reached the thermal turn-on point Ton (step S5 : NO), thecontrol unit 101 remains in step S5 and waits until the room temperature reaches the thermal turn-on point Ton.
与此相对地，在室温达到了热接通点Ton的情况下(步骤S5：是)，控制部101进一步判定是否从空气调节部进行热断开起经过了禁止时间(步骤S6)。若具体地进行说明，则控制部101基于计时部103的计时来判定从空气调节部进行热断开起的经过时间是否超过了预先规定的禁止时间。On the other hand, when the room temperature has reached the thermal ON point Ton (step S5: YES), thecontrol unit 101 further determines whether or not the prohibition time has elapsed since the air conditioning unit was thermally OFF (step S6). Specifically, thecontrol unit 101 determines whether or not the elapsed time since the thermal shutdown of the air-conditioning unit exceeds a predetermined prohibition time based on the timekeeping of thetimekeeping unit 103 .
在判定为从空气调节部进行热断开起未经过禁止时间的情况下(步骤S6：否)，控制部101停留在步骤S6，待机至在空气调节部从进行热断开起经过禁止时间为止。换言之，即使室温达到热接通点Ton，若从空气调节部进行热断开起未经过禁止时间，则控制部101也不使空气调节部进行热接通。When it is determined that the prohibition time has not elapsed since the air-conditioning unit was thermally turned off (step S6: NO), thecontrol unit 101 remains in step S6 and waits until the prohibition time has elapsed since the air-conditioning unit was thermally turned off . In other words, even if the room temperature reaches the thermal-on point Ton, thecontrol unit 101 does not turn the air-conditioning unit thermally on unless the prohibition time has elapsed since the air-conditioning unit was thermally off.
与此相对地，在判定为从空气调节部进行热断开起经过了禁止时间的情况下(步骤S6：是)，控制部101使空气调节部进行热接通(步骤S7)。若具体地进行说明，则控制部101控制压缩机21将转速变更为与设定温度相应的值，由此使压缩机21的驱动开始。由此，空调装置1开始室内空间71的空气调节。这里，在步骤S3～步骤S7中，控制部101作为空气调节控制部330发挥功能。On the other hand, when it is determined that the prohibition time has elapsed since the air-conditioning unit was thermally turned off (step S6 : YES), thecontrol unit 101 turns the air-conditioning unit thermally on (step S7 ). Specifically, thecontrol unit 101 starts the drive of thecompressor 21 by controlling thecompressor 21 to change the rotational speed to a value corresponding to the set temperature. Thereby, the air conditioning apparatus 1 starts air conditioning of theindoor space 71 . Here, in steps S3 to S7 , thecontrol unit 101 functions as the air-conditioning control unit 330 .
若空气调节部进行热断开，则控制部101使处理返回至步骤S1，并反复进行步骤S1～步骤S7的处理。换言之，控制部101反复进行以下处理：根据主体温度变更热断开点Toff，并且若室温达到热断开点Toff，则进行空气调节部的热断开，若室温达到热接通点Ton，则进行空气调节部的热接通。When the air-conditioning unit is thermally turned off, thecontrol unit 101 returns the process to step S1, and repeats the process of step S1 to step S7. In other words, thecontrol unit 101 repeats the processing of changing the thermal cutoff point Toff according to the main body temperature, and when the room temperature reaches the thermal cutoff point Toff, performs thermal cutoff of the air conditioner, and when the room temperature reaches the thermal cutoff point Ton, thecontrol unit 101 repeatedly performs the following processing. The heat of the air conditioning unit is turned on.
如以上说明的那样，对于实施方式1所涉及的空调装置1而言，若室温达到热断开点Toff，则使压缩机21的驱动停止，若室温达到热接通点Ton，则使压缩机21的驱动开始，由此对室内空间71进行空气调节。此时，在室内空间71内的主体温度相对低的情况下，与室内空间71内的主体温度相对高的情况相比，空调装置1将热断开点Toff设定为高的温度，由此根据主体温度来调整热断开点Toff的温度。As described above, in the air conditioner 1 according to Embodiment 1, when the room temperature reaches the thermal off point Toff, the drive of thecompressor 21 is stopped, and when the room temperature reaches the thermal on point Ton, the compressor is turned off The driving of 21 is started, whereby theindoor space 71 is air-conditioned. At this time, when the temperature of the main body in theindoor space 71 is relatively low, the air conditioner 1 sets the thermal disconnection point Toff to a higher temperature than when the temperature of the main body in theindoor space 71 is relatively high, thereby The temperature of the thermal disconnection point Toff is adjusted according to the body temperature.
这样，通过根据主体温度来调整热断开点Toff，能够抑制在刚热断开后的正经过压缩机21不能再次启动的禁止时间的期间，室温越过作为设定温度的热接通点Ton变化。因此，能够提高室内空间71内的舒适性。另外，在预测为室温变化量少的情况下，控制部101能够提前停止压缩机21的驱动。因此，实施方式1的空调装置1能够减少空气调节所涉及的耗电量。By adjusting the thermal off point Toff in accordance with the body temperature in this way, it is possible to prevent the room temperature from changing beyond the thermal on point Ton, which is the set temperature, during a period of time immediately after thermal off, during which thecompressor 21 cannot be restarted. . Therefore, the comfort in theindoor space 71 can be improved. In addition, when the amount of room temperature change is predicted to be small, thecontrol unit 101 can stop the drive of thecompressor 21 early. Therefore, the air conditioner 1 of Embodiment 1 can reduce the power consumption related to air conditioning.
实施方式2Embodiment 2
接下来，对实施方式2所涉及的空调装置1进行说明。实施方式1所涉及的空调装置1基于主体温度来预测室温变化量，并调整热断开点Toff。与此相对地，实施方式2所涉及的空调装置1作为用于室外机控制部51预测室温变化量的指标还包括室外温度检测部42所取得的外部空气温度的数据来进行处理。Next, the air conditioner 1 according toEmbodiment 2 will be described. The air conditioner 1 according to Embodiment 1 predicts the amount of room temperature change based on the main body temperature, and adjusts the thermal cutoff point Toff. On the other hand, the air conditioner 1 according toEmbodiment 2 handles the data including the outside air temperature acquired by the outdoortemperature detection unit 42 as an index for the outdoorunit control unit 51 to predict the room temperature change amount.
如在实施方式1中说明的图4和(2)式所示，室内空间71的主体温度从房屋3的外壁的温度受热而变化。并且，房屋3的外壁的温度受来自外部空气温度的热而变化。因此，室内空间71的主体温度根据外部空气温度而变化。例如，若外部空气温度上升，则主体温度延迟数小时而上升，若外部空气温度降低，则主体温度缓缓地降低。这样，能够通过外部空气温度来预测主体温度的变化。因此，通过取得外部空气温度，与仅使用主体温度的情况相比，能够预料至更久远的时间，来预测室内空间71的室温变化量。4 and the formula (2) described in Embodiment 1, the main body temperature of theindoor space 71 is changed by being heated from the temperature of the outer wall of thehouse 3 . Furthermore, the temperature of the outer wall of thehouse 3 is changed by the heat from the outside air temperature. Therefore, the main body temperature of theindoor space 71 changes according to the outside air temperature. For example, when the outside air temperature rises, the main body temperature rises with a delay of several hours, and when the outside air temperature decreases, the main body temperature gradually decreases. In this way, the change in the body temperature can be predicted from the outside air temperature. Therefore, by acquiring the outside air temperature, it is possible to predict the amount of room temperature change in theindoor space 71 over a longer period of time than when only the main body temperature is used.
实施方式2的设定部340根据由表面温度取得部320取得的主体温度和上述的指标取得部350所取得的外部空气温度的数据来设定热断开点Toff。若具体地进行说明，则设定部340与实施方式1的设定部340相同地，主体温度越低，将热断开点Toff设定为越高的温度。另一方面，若主体温度相同，则设定部340以使得外部空气温度相对低的情况比外部空气温度相对高的情况高的方式设定热断开点Toff的温度。空气调节控制部330这样按照由设定部340根据主体温度和外部空气温度设定的热断开点Toff来使压缩机21的驱动停止。Thesetting unit 340 of the second embodiment sets the thermal cutoff point Toff based on the data of the body temperature acquired by the surfacetemperature acquisition unit 320 and the outside air temperature acquired by the above-describedindex acquisition unit 350 . Specifically, thesetting unit 340 sets the thermal shutdown point Toff to a higher temperature as the body temperature is lower, as in thesetting unit 340 of the first embodiment. On the other hand, if the main body temperature is the same, thesetting unit 340 sets the temperature of the thermal cutoff point Toff so that the temperature of the thermal cutoff point Toff is higher when the outside air temperature is relatively low than when the outside air temperature is relatively high. The air-conditioning control unit 330 thus stops the drive of thecompressor 21 at the thermal cutoff point Toff set by thesetting unit 340 based on the body temperature and the outside air temperature.
与此相对地，在制冷运转时，设定部340将热断开点Toff1和热断开点Toff2设定为比热接通点Ton低的温度。并且，设定部340将外部空气温度相对低的情况下的热断开点Toff1设定为比外部空气温度相对高的情况下的热断开点Toff2高的温度。这样，根据外部空气温度来设定热断开点Toff1和热断开点Toff2，由此在预测到由于外部空气温度低而室温降低的情况下，压缩机21提前停止。由此，能够抑制室内空间71过冷，舒适性提高，并且还能够减少耗电量。另外，在预测到由于外部空气温度高而室温上升的情况下，压缩机21长时间运转。因此，空调装置1能够充分地制冷。On the other hand, during the cooling operation, thesetting unit 340 sets the thermal off point Toff1 and the thermal off point Toff2 to a temperature lower than the thermal on point Ton. Then, thesetting unit 340 sets the thermal cutoff point Toff1 when the outside air temperature is relatively low to a higher temperature than the thermal cutoff point Toff2 when the outside air temperature is relatively high. In this way, the thermal cutoff point Toff1 and the thermal cutoff point Toff2 are set in accordance with the outside air temperature, whereby thecompressor 21 is stopped early when it is predicted that the room temperature will drop due to the low outside air temperature. Thereby, theindoor space 71 can be suppressed from being too cold, the comfort can be improved, and the power consumption can also be reduced. In addition, when it is predicted that the room temperature will rise due to the high outside air temperature, thecompressor 21 is operated for a long time. Therefore, the air-conditioning apparatus 1 can sufficiently cool.
如以上说明的那样，实施方式2所涉及的空调装置1在主体温度的基础上还基于外部空气温度，根据主体温度和外部空气温度来调整热断开点Toff和热断开点Toff。通过使用外部空气温度来进行热断开点的设定，能够高精度地预测至更久远的室温变化。因此，能够更恰当地设定热断开点Toff和热断开点Toff，从而能够使室内空间71的舒适性进一步提高。As described above, the air conditioner 1 according toEmbodiment 2 adjusts the thermal cutoff point Toff and the thermal cutoff point Toff according to the body temperature and the outside air temperature based on the outside air temperature in addition to the body temperature. By setting the thermal disconnection point using the outside air temperature, it is possible to predict the room temperature change in the long term with high accuracy. Therefore, the thermal cutoff point Toff and the thermal cutoff point Toff can be set more appropriately, and the comfort of theindoor space 71 can be further improved.
这里，室外温度检测部42也可以设置于除室外机11以外的场所。例如，指标取得部350也可以经由外部的电气通信线路等来取得包括在房屋3的外部设置的温度传感器所检测到的外部空气温度数据在内的信号。另外，室外温度检测部42并不限定于温度传感器等危机等，也可以取得天气预报、气象数据等经由外部的电气通信线路等而获得的外部空气温度数据，检测外部空气温度。Here, the outdoortemperature detection unit 42 may be installed in a place other than theoutdoor unit 11 . For example, theindex acquisition unit 350 may acquire a signal including outside air temperature data detected by a temperature sensor installed outside thehouse 3 via an external electrical communication line or the like. In addition, the outdoortemperature detection unit 42 is not limited to a crisis such as a temperature sensor, and may acquire outside air temperature data such as weather forecast and weather data through an external electrical communication line or the like, and detect the outside air temperature.
实施方式3Embodiment 3
接下来，对实施方式3进行说明。在实施方式3中，上述的设定部340根据表面温度取得部320所取得的主体温度、和指标取得部350所取得的外部空气温度，来进行与自然换气有关的报告所涉及的处理。而且，设定部340基于处理将报告信号向报告部58发送，而对用户进行报告。这里，以下，换气基本上是指不使用换气设备而是打开窗4等来进行换气的自然换气。Next,Embodiment 3 will be described. InEmbodiment 3, the above-describedsetting unit 340 performs processing related to a report related to natural ventilation based on the body temperature acquired by the surfacetemperature acquisition unit 320 and the outside air temperature acquired by theindex acquisition unit 350 . Then, thesetting unit 340 transmits a report signal to thereport unit 58 based on the processing, and reports to the user. Hereinafter, ventilation basically refers to natural ventilation in which ventilation is performed by opening thewindow 4 or the like without using a ventilation device.
若具体地进行说明，则设定部340根据与表面温度取得部320所取得的主体温度、和由指标取得部350取得的外部空气温度有关的数据，预测今后的室温变化量。而且，设定部340若基于预测到的室温变化量判定为是适合于换气的环境条件，则向报告部58发送催促换气的报告信号，而对用户进行报告。另外，设定部340还对换气的结束进行判定，向报告部58发送催促换气的结束的报告信号，而对用户进行报告。Specifically, thesetting unit 340 predicts the future room temperature change amount based on data related to the body temperature acquired by the surfacetemperature acquisition unit 320 and the outside air temperature acquired by theindex acquisition unit 350 . Then, when thesetting unit 340 determines that it is an environmental condition suitable for ventilation based on the predicted change in room temperature, it transmits a notification signal for urging ventilation to thenotification unit 58 and notifies the user. In addition, thesetting unit 340 also determines the end of ventilation, and transmits a notification signal for prompting the end of the ventilation to thenotification unit 58 to notify the user.
例如，设定部340若预测为因夏季的外部空气温度影响而室温变低而导致室内空间71的热负荷变少，则向报告部58发送催促换气的报告信号。另外，若预测从室温低的状态向变高的状态变化，则其后能够预测室温变高，因此进行催促换气的报告。室内空间71的热负荷少，在处于热平衡的状态中催促换气。由此，能够防止相对于室内环境的能量的损失，实现节能，并且能够进行空气的更换。而且，可以认为通过进行室内空间71的换气，对传染病预防也具有效果。For example, thesetting unit 340 transmits a notification signal for urging ventilation to thenotification unit 58 when it is predicted that the heat load of theindoor space 71 will decrease due to a decrease in room temperature due to the influence of the outside air temperature in summer. In addition, if it is predicted to change from the state where the room temperature is low to the state where the room temperature is high, it is possible to predict that the room temperature will be high after that, and therefore, a notification is made to promote ventilation. The thermal load of theindoor space 71 is small, and ventilation is urged in a state of thermal equilibrium. Thereby, the loss of energy with respect to the indoor environment can be prevented, energy saving can be achieved, and air replacement can be performed. In addition, it is considered that the ventilation of theindoor space 71 also has an effect on the prevention of infectious diseases.
图9是表示实施方式3中的换气报告所涉及的处理的流程的图。这里，上述的设定部340、表面温度取得部320以及指标取得部350所进行的处理实质上由控制部101进行。因此，这里，作为由控制部101进行处理的情况进行说明。FIG. 9 is a diagram showing a flow of processing related to a ventilation report inEmbodiment 3. FIG. Here, the processing performed by thesetting unit 340 , the surfacetemperature obtaining unit 320 , and theindex obtaining unit 350 described above is substantially performed by thecontrol unit 101 . Therefore, here, the case where the processing is performed by thecontrol unit 101 will be described.
控制部101执行图9所示的换气报告处理。控制部101进行预测室内空间71的室温变化量的热负荷响应控制(步骤S110)。这里，如在实施方式1中说明的那样，控制部101基于表面温度检测部43的检测所涉及的主体温度来预测室温变化量。然而，并不限定于此。如在上述的实施方式1中说明的那样，(2)式中的主体温度根据房屋3中的墙壁的温度而变化，墙壁的温度受外部空气温度的影响。因此，如在实施方式2中说明的那样，控制部101也可以根据室外温度检测部42的检测所涉及的外部空气温度的数据来修正表面温度检测部43的检测所涉及的主体温度数据等，从而预测室温变化量。Thecontrol unit 101 executes the ventilation reporting process shown in FIG. 9 . Thecontrol part 101 performs thermal load response control which predicts the room temperature change amount of the indoor space 71 (step S110). Here, as described in Embodiment 1, thecontrol unit 101 predicts the amount of room temperature change based on the body temperature involved in the detection by the surfacetemperature detection unit 43 . However, it is not limited to this. As described in the above-mentioned Embodiment 1, the main body temperature in the formula (2) changes according to the temperature of the wall in thehouse 3, and the temperature of the wall is affected by the temperature of the outside air. Therefore, as described inEmbodiment 2, thecontrol unit 101 may correct the main body temperature data related to the detection of the surfacetemperature detection unit 43 based on the data of the outside air temperature related to the detection of the outdoortemperature detection unit 42, and the like, Thereby predicting the amount of room temperature change.
控制部101基于室温变化量的预测进行判定今后的热负荷的趋势的热负荷趋势判定(步骤S120)。如图9所示，在实施方式3中，控制部101判定热负荷的趋势是处于增加趋势、中间趋势还是减少趋势。控制部101若预测为室温变化量在预定的设定变化量范围以内，则判定为室内空间71的热负荷处于不增加和减少的中间趋势。另外，控制部101若预测为室温变化量比设定变化范围多，则判定为热负荷上升而处于增加趋势。而且，控制部101若预测为室温变化量比设定变化范围少，则判定为热负荷减少而处于减少趋势。这里，控制部101虽然判定了增加、减少以及中间这3个模式的热负荷趋势，但也可以判定增加和减少这两个模式的趋势。Thecontrol unit 101 performs thermal load trend determination for determining the future thermal load trend based on the prediction of the room temperature change amount (step S120 ). As shown in FIG. 9 , inEmbodiment 3, thecontrol unit 101 determines whether the trend of the thermal load is an increasing trend, an intermediate trend, or a decreasing trend. When thecontrol unit 101 predicts that the room temperature change amount is within the predetermined set change amount range, thecontrol unit 101 determines that the thermal load of theindoor space 71 is in an intermediate trend of not increasing and decreasing. In addition, when thecontrol unit 101 predicts that the amount of change in the room temperature is larger than the set change range, thecontrol unit 101 determines that the thermal load increases and tends to increase. Then, when thecontrol unit 101 predicts that the amount of change in the room temperature is smaller than the set change range, it determines that the thermal load has decreased and is in a decreasing trend. Here, thecontrol unit 101 determines the thermal load trends of the three patterns of increase, decrease, and intermediate, but may determine the trends of the two patterns of increase and decrease.
图10是对实施方式3中的热负荷的趋势的变化进行说明的图。首先，对于从中间趋势向减少趋势变化的情况，如图10所示，例如，在假定为夏季时，在从中午到傍晚太阳下落而外部空气温度下降时，由室温变化量的预测进行的热负荷的趋势从中间趋势向减少趋势变化。另一方面，对于从中间趋势向增加趋势变化的情况，如图10所示，例如，在假定为夏季的情况下，在朝阳开始照射而外部空气温度上升时，由室温变化量的预测进行的热负荷的趋势从中间趋势向增加趋势变化。FIG. 10 is a diagram for explaining a change in the tendency of the thermal load inEmbodiment 3. FIG. First, as shown in Fig. 10, for a case of changing from an intermediate trend to a decreasing trend, for example, in the case of assuming summer, when the sun sets from noon to evening and the outside air temperature drops, the heat generated by the prediction of the amount of room temperature change The trend of the load changes from an intermediate trend to a decreasing trend. On the other hand, as shown in FIG. 10 , for the case of changing from the intermediate trend to the increasing trend, for example, in the case of assuming summer, when the rising sun starts to shine and the outside air temperature rises, the prediction of the amount of room temperature change is performed. The trend of heat load changes from an intermediate trend to an increasing trend.
控制部101若根据室温变化量判定为热负荷的变化少的、从中间趋势向增加趋势变化或者从中间趋势向减少趋势变化，则进行判定是否将催促换气这一主旨的报告信号向报告部58发送的换气报告判定(步骤S130)。例如，若通过与遥控器55的换气报告有关的设定而进行了不报告这一主旨的设定，则不向报告部58发送报告信号。控制部101若判定为不向报告部58发送报告信号，则返回至步骤S110。另外，控制部101若判定为发送催促换气开始这一主旨的报告信号，则向报告部58发送报告信号，报告催促换气这一主旨(步骤S140)。Thecontrol unit 101 determines whether or not to send a notification signal to the notification unit for the purpose of urging ventilation when it is determined from the amount of room temperature change that the heat load has changed less, from an intermediate trend to an increasing trend, or from an intermediate trend to a decreasing trend. The ventilation report sent by 58 is determined (step S130). For example, if the setting to not report is made by the setting related to the ventilation report of theremote controller 55 , the report signal is not sent to thereport unit 58 . When thecontrol unit 101 determines that the report signal is not to be transmitted to thereport unit 58, the process returns to step S110. In addition, when thecontrol unit 101 determines to transmit a report signal to urge the start of ventilation, it transmits a report signal to thenotification unit 58 to report the fact that the ventilation is urged (step S140).
而且，控制部101判定是否结束换气(步骤S150)。在实施方式3中，控制部101例如根据从向报告部58发送催促换气的报告信号起是否经过了结束设定时间来判定。但是，换气结束所涉及的判定并不特别地限定。这里，计时部103测量时间。而且，控制部101若判定为结束换气，则将催促换气结束这一主旨的报告信号向报告部58发送(步骤S160)。Then, thecontrol unit 101 determines whether or not to end the ventilation (step S150). In the third embodiment, thecontrol unit 101 determines, for example, whether or not the end set time has elapsed since the notification signal for prompting ventilation is transmitted to thenotification unit 58 . However, the determination regarding the end of ventilation is not particularly limited. Here, thetimer unit 103 measures time. Then, when thecontrol unit 101 determines that the ventilation is ended, it transmits a notification signal to thenotification unit 58 to urge the end of the ventilation (step S160).
图11是表示由报告部58进行的报告的一个例子的图。这里，对基于报告信号进行与换气有关的报告的报告部58进行说明。在图11中，示出了在遥控器55所具有的显示装置进行与换气有关的显示的例子。这里，如上述的那样，由报告部58进行的报告并不限定于显示。例如，也可以将室内机13所具有的蜂鸣器等声音产生装置作为报告部58进行基于鸣动的报告。另外，也可以将室内机13所具有的LED灯等发光装置作为报告部58来进行基于点亮、闪烁等的报告。而且，报告催促换气开始这一主旨的报告部58与报告催促换气结束这一主旨的报告部58也可以不同。FIG. 11 is a diagram showing an example of reporting by thereporting unit 58 . Here, thereport unit 58 that reports the ventilation based on the report signal will be described. FIG. 11 shows an example in which display related to ventilation is performed on the display device included in theremote controller 55 . Here, as described above, the report by thereport unit 58 is not limited to the display. For example, a sound generating device such as a buzzer included in theindoor unit 13 may be used as thenotification unit 58 to perform notification based on the sound. In addition, a light-emitting device such as an LED lamp included in theindoor unit 13 may be used as thenotification unit 58 to perform notification by lighting, flickering, or the like. Furthermore, thereport unit 58 that reports the purpose of urging the start of ventilation may be different from thereport unit 58 that reports the purpose of urging the end of the ventilation.
如以上那样，根据实施方式3，控制部101根据表面温度检测部43的检测所涉及的主体温度数据来预测室温变化量，并基于由预测进行的室内空间71的热负荷的趋势，来将催促用户进行换气开始这一主旨的报告信号向报告部58发送。因此，能够在室内空间71的热负荷的变化少的时刻进行换气，从而能够实现节能。例如，在空调装置1进行空气调节的情况下，能够直接在空调装置1的运转中实现节能。另外，即使在空调装置1不处于运转中，也能够抑制由换气引起的热负荷增加，也可以不进行空调装置1的运转等能够期待节能。As described above, according to the third embodiment, thecontrol unit 101 predicts the room temperature change amount based on the body temperature data related to the detection by the surfacetemperature detection unit 43, and based on the trend of the thermal load of theindoor space 71 based on the prediction, prompts the A notification signal to the effect that the user has started ventilation is transmitted to thenotification unit 58 . Therefore, ventilation can be performed at a timing when the change in the thermal load of theindoor space 71 is small, and energy saving can be achieved. For example, when the air conditioner 1 performs air conditioning, energy saving can be realized directly in the operation of the air conditioner 1 . In addition, even when the air conditioner 1 is not in operation, an increase in heat load due to ventilation can be suppressed, and energy saving can be expected without operating the air conditioner 1 or the like.
实施方式4Embodiment 4
接下来，对实施方式4进行说明。实施方式4的室外机控制部51所具有的设定部340，基于室内机13所具有的人体检测部49的检测，来判定室内空间71有没有人，并判定是否向报告部58发送报告信号。这是因为，当在室内空间71没有人时，即使进行报告，也无法进行窗4的开闭。Next,Embodiment 4 will be described. Thesetting unit 340 included in the outdoorunit control unit 51 of the fourth embodiment determines whether or not there is a person in theindoor space 71 based on the detection by the humanbody detection unit 49 included in theindoor unit 13 , and determines whether or not to transmit a notification signal to thenotification unit 58 . This is because when there is no one in theindoor space 71, thewindow 4 cannot be opened and closed even if a notification is made.
图12是表示实施方式4所涉及的换气报告所涉及的处理流程的图。对于标注了与图9相同的步骤编号的处理，进行与在实施方式3中说明的处理相同的处理。步骤S110和步骤S120与在实施方式3中说明的处理相同。FIG. 12 is a diagram showing a flow of processing related to a ventilation report according toEmbodiment 4. FIG. The same processing as that described inEmbodiment 3 is performed for the processing denoted by the same step numbers as in FIG. 9 . Steps S110 and S120 are the same as the processing described in the third embodiment.
在实施方式4中，控制部101若在步骤S120的热负荷趋势判定中判定为热负荷从中间趋势向增加趋势变化或者从中间趋势向减少趋势变化，则判定室内空间71是否存在人(步骤S121)。这里，控制部101基于人体检测部49的检测进行判定。控制部101若判定为在室内空间71没有人，则返回至步骤S110。InEmbodiment 4, thecontrol unit 101 determines whether there is a person in theindoor space 71 when it is determined that the heat load is changing from an intermediate trend to an increasing trend or from an intermediate trend to a decreasing trend in the heat load trend determination in step S120 (step S121 ). ). Here, thecontrol unit 101 makes a determination based on the detection by the humanbody detection unit 49 . When thecontrol unit 101 determines that there is no person in theindoor space 71, it returns to step S110.
另一方面，控制部101若判定为在室内空间71存在人，则判定是否将催促换气开始这一主旨的报告信号向报告部58发送(步骤S130)。对于步骤S130以后的处理，与实施方式3相同。On the other hand, when it is determined that a person is present in theindoor space 71, thecontrol unit 101 determines whether or not to transmit a notification signal to thenotification unit 58 to prompt the start of ventilation (step S130). The processing after step S130 is the same as that of the third embodiment.
如以上那样，根据实施方式4，控制部101若判定为在室内空间71不存在人，则不发送报告信号，不进行与换气有关的报告。因此，能够防止在开闭窗4的人不存在的状态下进行报告等无意义的报告。As described above, according toEmbodiment 4, when thecontrol unit 101 determines that there is no person in theindoor space 71, it does not transmit a report signal, and does not report the ventilation. Therefore, it is possible to prevent meaningless reports, such as reports, from being issued in a state where the person opening and closing thewindow 4 does not exist.
实施方式5Embodiment 5
接下来，对实施方式5进行说明。在实施方式5中，控制部101取得日照量检测部47的检测所涉及的日照量数据来作为预测室内空间71的室温变化量时的指标。数据的取得通过指标取得部350的处理来进行。Next, Embodiment 5 will be described. In the fifth embodiment, thecontrol unit 101 acquires the solar radiation amount data related to the detection by the solar radiationamount detection unit 47 as an index when predicting the room temperature change amount of theindoor space 71 . The acquisition of data is performed by the processing of theindex acquisition unit 350 .
日照量是从太阳受到的放射能的量。如上述的那样，日照量检测部47设置于室内机13、室内空间71的窗4的附近、室外空间72等能够检测日照量的场所等来检测日照量。控制部101经由通信部104取得日照量检测部47的检测所涉及的信号所包括的日照量数据。The amount of insolation is the amount of radiant energy received from the sun. As described above, the solar radiationamount detection unit 47 is installed in theindoor unit 13 , near thewindow 4 of theindoor space 71 , at a place where the solar radiation amount can be detected, such as theoutdoor space 72 , and the like to detect the solar radiation amount. Thecontrol unit 101 acquires, via thecommunication unit 104 , the solar radiation amount data included in the signal related to the detection by the solar radiationamount detection unit 47 .
如在实施方式1中说明的图4和(2)式所示，房屋3所涉及的主体温度从通过窗4的日照受热而变化。另外，房屋3的外壁的温度从日照受热而变化。因此，室内空间71的主体温度根据日照量而变化。例如，若房屋3的外壁受到日照而被加热，则热通过墙壁，由此贯流负荷增加，主体温度上升。另外，若从窗4进入的日照到达内壁，则日照负荷增加，主体温度缓缓地上升。另一方面，若日照消失，则主体温度缓缓地降低。这样，能够通过日照量预测主体温度的变化。因此，控制部101取得日照量检测部47的检测所涉及的信号所包括的日照量数据来修正表面温度检测部43的检测所涉及的主体温度数据等，而用于室温变化量的预测。由此，与将表面温度检测部43的表面温度作为主体温度相比，能够预料至更久远的时间来预测室内空间71的室温变化量。室温变化量的预测通过设定部340的处理来进行。As shown in FIG. 4 and Equation ( 2 ) described in Embodiment 1, the temperature of the main body related to thehouse 3 changes from being heated by sunlight through thewindow 4 . In addition, the temperature of the outer wall of thehouse 3 changes by being heated by sunlight. Therefore, the main body temperature of theindoor space 71 changes according to the amount of sunlight. For example, when the outer wall of thehouse 3 is heated by sunlight, the heat passes through the wall, whereby the cross-flow load increases, and the temperature of the main body rises. In addition, when the sunlight entering from thewindow 4 reaches the inner wall, the sunlight load increases, and the temperature of the main body gradually rises. On the other hand, when the sunlight disappears, the main body temperature gradually decreases. In this way, it is possible to predict the change in the temperature of the main body from the amount of sunlight. Therefore, thecontrol unit 101 acquires the solar radiation amount data included in the signal related to the detection by the solar radiationamount detection unit 47 and corrects the main body temperature data and the like related to the detection by the surfacetemperature detection unit 43, and uses it to predict the amount of room temperature change. As a result, the amount of room temperature change in theindoor space 71 can be predicted over a longer period of time than when the surface temperature of the surfacetemperature detection unit 43 is used as the main body temperature. The prediction of the room temperature change amount is performed by the processing of thesetting unit 340 .
这样，实施方式5中的控制部101使用日照量检测部47的检测所涉及的日照量数据来进行室温变化量的预测。通过使用日照量数据，能够高精度地预测更久远的室温变化量。因此，能够更恰当地设定进行催促换气的开始等的报告的时刻。而且，能够使室内空间71的操作性进一步提高。In this way, thecontrol unit 101 in the fifth embodiment predicts the amount of room temperature change using the solar radiation amount data related to the detection by the solar radiationamount detection unit 47 . By using the solar radiation data, it is possible to predict the amount of room temperature change with high accuracy over a longer period of time. Therefore, it is possible to more appropriately set the timing for reporting the start of the accelerated ventilation or the like. Furthermore, the operability of theindoor space 71 can be further improved.
这里，在实施方式5中，对于日照量检测部47具有红外线传感器的情况进行了说明，但并不限定于此。例如，日照量检测部47也可以具有照度传感器，并根据照度数据获得日照量数据。另外，日照量检测部47也可以具有照相机等，并根据照相机所拍摄到的室内空间71的可视图像数据获得日照量数据。并且，也可以将能够获得基于太阳光发电设备的发电量、天气预报或者气象等数据的设备等作为日照量检测部47来获得日照量数据。Here, in Embodiment 5, the case where the solar radiationamount detection unit 47 has the infrared sensor has been described, but the present invention is not limited to this. For example, the solar radiationamount detection unit 47 may include an illuminance sensor, and obtain solar radiation amount data from the illuminance data. In addition, the solar radiationamount detection unit 47 may include a camera or the like, and obtain solar radiation amount data from visible image data of theindoor space 71 captured by the camera. In addition, the solar radiation amount data may be acquired as the solar radiationamount detection unit 47 by a device or the like that can obtain data such as the power generation amount, weather forecast, or weather based on the solar photovoltaic power generation device.
实施方式6Embodiment 6
接下来，对实施方式6的空调装置1进行说明。在实施方式5中，控制部101取得具有室内空间71的房屋3的主体等的隔热性能所涉及的数据，来作为预测室内空间71的室温变化量的指标的数据。数据的取得通过指标取得部350的处理来进行。Next, the air conditioner 1 of Embodiment 6 will be described. In Embodiment 5, thecontrol part 101 acquires the data concerning the thermal insulation performance of the main body of thehouse 3 etc. which have theindoor space 71, as data of the index which predicts the room temperature change amount of theindoor space 71. The acquisition of data is performed by the processing of theindex acquisition unit 350 .
作为建筑物的房屋3的主体等的隔热性能是表示热在室内空间71与室外空间72之间的传导容易度的指标。隔热性能能够通过外皮平均热贯流率或者热损失系数等来估算。控制部101取得用户对遥控器55输入的隔热性能数据。另外，控制部101还可以通过从空调装置1的过去的空气调节能力进行学习处理来取得表示室内空间71的隔热性能的信息。取得的隔热性能数据例如存储于存储部102。例如，由设定部340等来进行学习处理。The thermal insulation performance of the main body or the like of thehouse 3 which is a building is an index showing the ease of heat conduction between theindoor space 71 and theoutdoor space 72 . The thermal insulation performance can be estimated by the average heat flux rate of the skin or the heat loss coefficient. Thecontrol unit 101 acquires the thermal insulation performance data input by the user to theremote controller 55 . In addition, thecontrol unit 101 may acquire information indicating the thermal insulation performance of theindoor space 71 by performing a learning process from the past air conditioning capability of the air conditioner 1 . The acquired heat insulating performance data is stored in thestorage unit 102, for example. For example, the learning process is performed by thesetting unit 340 or the like.
如在实施方式1中说明的图4和(2)式所示，房屋3所涉及的主体温度依赖于隔热性能来变化。隔热性能越高，换气时的室温越难以变化，隔热性能越低，换气时的室温越容易变化。因此，控制部101取得隔热性能数据，并使用在主体温度的计算等室温变化量的预测中。由此，相比于将表面温度检测部43的表面温度作为主体温度，能够预料至更久远的时间来预测室内空间71内的室温变化量。室温变化量的预测通过设定部340的处理来进行。As shown in FIG. 4 and the formula (2) described in Embodiment 1, the main body temperature related to thehouse 3 changes depending on the thermal insulation performance. The higher the thermal insulation performance, the more difficult it is to change the room temperature during ventilation, and the lower the thermal insulation performance, the easier it is to change the room temperature during ventilation. Therefore, thecontrol part 101 acquires the heat insulating performance data, and uses it for the prediction of the room temperature change amount, such as calculation of a main body temperature. Thereby, the amount of room temperature change in theindoor space 71 can be predicted over a longer period of time than when the surface temperature of the surfacetemperature detection unit 43 is used as the main body temperature. The prediction of the room temperature change amount is performed by the processing of thesetting unit 340 .
这样，实施方式5中的控制部101的设定部340使用房屋3的隔热性能数据来进行室温变化量的预测。通过使用隔热性能数据，能够高精度地预测更久远的室温变化量。因此，能够在更恰当的时刻进行催促换气开始等的报告。In this way, thesetting unit 340 of thecontrol unit 101 in the fifth embodiment predicts the amount of room temperature change using the thermal insulation performance data of thehouse 3 . By using the thermal insulation performance data, it is possible to predict the amount of room temperature change with high accuracy over a longer period of time. Therefore, it is possible to report the start of ventilation and the like at a more appropriate timing.

实施方式7Embodiment 7
接下来，对实施方式7进行说明。在实施方式7中，控制部101取得上述的室内空间71的内部发热量数据，来作为在预测室内空间71的室温变化量时使用的指标的数据。数据的取得通过指标取得部350的处理来进行。Next, Embodiment 7 will be described. In Embodiment 7, thecontrol unit 101 acquires the above-described internal heating value data of theindoor space 71 as data of an index used in predicting the amount of room temperature change in theindoor space 71 . The acquisition of data is performed by the processing of theindex acquisition unit 350 .
如在实施方式1中说明的(3)式那样，内部发热量能够根据室内空间71的室内人数、设置于室内空间71的照明、来自家电设备和燃烧器具的发热量等来估算。因此，控制部101使用主体温度和内部发热量的数据来预测处理室温变化量。The internal calorific value can be estimated from the number of people in theindoor space 71 , the lighting installed in theindoor space 71 , the calorific value from household electrical appliances and combustion appliances, and the like, as in the formula (3) described in Embodiment 1. Therefore, thecontrol unit 101 uses the data of the main body temperature and the internal heat generation amount to predict the amount of change in the processing room temperature.
这里，控制部101可以通过遥控器55所发送的设定来取得内部发热量数据，也可以通过由人体检测部49、红外线传感器、照相机等检测室内人数、照明、家电设备以及燃烧设备的发热来取得。并且，指标取得部350也可以经由电气通信线路等取得从外部设备发送的室内人数、设备的使用状况等数据，来作为内部发热量数据。Here, thecontrol unit 101 may acquire the internal heating value data through the setting sent from theremote controller 55, or may detect the number of people in the room, lighting, home appliances, and combustion equipment by the humanbody detection unit 49, infrared sensors, cameras, and the like. get. In addition, theindex acquisition unit 350 may acquire data such as the number of people in the room, the usage status of the equipment, and the like transmitted from the external equipment via an electric communication line or the like, as the internal heat generation data.
这样，在实施方式7中，控制部101在主体温度的基础上取得内部发热量作为数据，并根据主体温度和内部发热量来进行室温变化量的预测。通过使用内部发热量数据，能够高精度地预测更久远的室温变化量。因此，能够在更恰当的时刻进行催促换气开始等的报告。而且，能够使室内空间71的舒适性和节能性进一步提高。In this way, in Embodiment 7, thecontrol unit 101 acquires the internal heating value as data in addition to the body temperature, and predicts the amount of room temperature change based on the body temperature and the internal heating value. By using the internal calorific value data, it is possible to predict the amount of room temperature change with high accuracy over a longer period of time. Therefore, it is possible to report the start of ventilation and the like at a more appropriate timing. Furthermore, the comfort and energy saving of theindoor space 71 can be further improved.
实施方式8Embodiment 8
接下来，对实施方式8进行说明。在实施方式8中，控制部101取得室内空间71的窗开闭检测部45的检测所涉及的窗开闭数据，来作为预测室内空间71的室温变化量时的指标。数据的取得通过指标取得部350的处理来进行。Next, Embodiment 8 will be described. In the eighth embodiment, thecontrol unit 101 acquires window opening/closing data related to detection by the window opening/closing detection unit 45 of theindoor space 71 as an index for predicting the amount of room temperature change in theindoor space 71 . The acquisition of data is performed by the processing of theindex acquisition unit 350 .
图13是表示实施方式8所涉及的换气报告所涉及的处理流程的图。对于标注了与图9相同的步骤编号的处理，进行与在实施方式3中说明的处理相同的处理。对于步骤S110和步骤S120，与实施方式3相同。13 is a diagram showing a flow of processing related to the ventilation report according to the eighth embodiment. The same processing as that described inEmbodiment 3 is performed for the processing denoted by the same step numbers as in FIG. 9 . The steps S110 and S120 are the same as those in the third embodiment.
在实施方式4中，控制部101若在步骤S120的热负荷趋势判定中判定为热负荷从中间趋势向增加趋势变化或者从中间趋势向减少趋势变化，则判定热负荷是否是增加趋势(步骤S122)。控制部101若判定为热负荷处于增加趋势，则基于窗开闭检测部45的检测所涉及的窗开闭数据，来判定窗4是否打开(步骤S123)。控制部101若判定为窗4关闭，则返回至步骤S110。InEmbodiment 4, thecontrol unit 101 determines whether or not the thermal load has an increasing trend if it is determined in the thermal load trend determination in step S120 that the thermal load is changing from an intermediate trend to an increasing trend or from an intermediate trend to a decreasing trend (step S122 ) ). When thecontrol unit 101 determines that the thermal load tends to increase, it determines whether or not thewindow 4 is open based on the window opening/closing data related to the detection by the window opening/closing detection unit 45 (step S123). When thecontrol unit 101 determines that thewindow 4 is closed, the process returns to step S110.
另一方面，控制部101若判定为窗4打开，则判定是否将催促换气开始这一主旨的报告信号向报告部58发送(步骤S130)。对于步骤S130以后的处理，与实施方式3相同。On the other hand, when it is determined that thewindow 4 is open, thecontrol unit 101 determines whether or not to transmit a notification signal to thenotification unit 58 to prompt the start of ventilation (step S130 ). The processing after step S130 is the same as that of the third embodiment.
这里，在实施方式8中，虽然通过窗开闭检测部45基于窗4的开闭，但并不仅限定于窗4。例如也可以检测门、间壁等那样的设置于室内空间71与室外空间72的边界部分的能够开闭的部分的开闭状况等并作为数据利用。控制部101可以经由遥控器55取得门等的开闭状况数据，也可以通过红外线传感器或者图像传感器来取得。而且，另外，控制部101也可以经由电气通信线路等而从外部设备取得与开闭有关的数据。Here, in the eighth embodiment, thewindow 4 is opened and closed by the window opening andclosing detection unit 45 , but it is not limited to thewindow 4 . For example, the opening and closing status of an openable and closable portion provided at the boundary between theindoor space 71 and theoutdoor space 72 such as a door and a partition wall may be detected and used as data. Thecontrol unit 101 may acquire opening/closing status data of a door or the like via theremote controller 55, or may acquire it via an infrared sensor or an image sensor. In addition, thecontrol unit 101 may acquire data related to opening and closing from an external device via an electric communication line or the like.
这样，在实施方式8中，控制部101在主体温度的基础上还基于窗开闭检测部45的窗开闭数据，根据主体温度和窗开闭的数据来调整换气报告所涉及的报告信号的时刻。通过使用与开闭部的开闭有关的数据，能够更准确地预测室内空间71的室温变化量，能够判定是否充分地进行了换气，从而能够使室内空间71的操作性进一步提高。As described above, in the eighth embodiment, thecontrol unit 101 adjusts the report signal related to the ventilation report based on the body temperature and the window opening/closing data based on the window opening/closing data of the window opening/closing detection unit 45 in addition to the body temperature. moment. By using the data related to the opening and closing of the opening and closing parts, the amount of change in room temperature of theindoor space 71 can be predicted more accurately, and it can be determined whether ventilation is sufficiently performed, and the operability of theindoor space 71 can be further improved.
这里，在实施方式8中，控制部101也可以在室内空间71的窗开闭检测部45的窗开闭数据的基础上或者代替窗开闭数据，取得在室内空间71设置的换气设备的运转状态数据。换气设备是指对室内空间71进行换气的换气扇、抽油烟机等设备。对于换气设备的运转状态数据，控制部101可以经由遥控器55取得，可以通过红外线传感器或者图像传感器取得，也可以经由外部的电气通信线路等来取得。Here, in Embodiment 8, thecontrol unit 101 may acquire the data of the ventilation equipment installed in theindoor space 71 in addition to or instead of the window opening/closing data of the window opening/closing detection unit 45 of theindoor space 71 . Operational status data. The ventilation equipment refers to equipment such as a ventilation fan and a range hood that ventilate theindoor space 71 . The operation state data of the ventilation equipment may be acquired by thecontrol unit 101 via theremote controller 55 , may be acquired by an infrared sensor or an image sensor, or may be acquired via an external electrical communication line or the like.
这里，在换气设备正运转的情况下，由于大量的空气在室内空间71与室外空间72之间移动，因此室内空间71所涉及的隔热性能降低。其结果是，在自然换气时，室温容易变化。因此，若主体温度相同，则控制部101将到换气结束为止的时间即窗检测设定时间，在换气设备没有运转的情况下比换气设备正运转的情况设定得长。这样，通过使用换气设备的运转状态数据，能够更恰当地预测室内空间71的自然换气的变化。因此，能够使室内空间71的舒适性与节能性进一步提高。Here, when the ventilation equipment is operating, since a large amount of air moves between theindoor space 71 and theoutdoor space 72, the thermal insulation performance related to theindoor space 71 is lowered. As a result, the room temperature tends to change during natural ventilation. Therefore, when the main body temperature is the same, thecontrol unit 101 sets the window detection setting time, which is the time until the end of ventilation, to be longer when the ventilation equipment is not operating than when the ventilation equipment is operating. In this way, by using the operating state data of the ventilation equipment, it is possible to more appropriately predict changes in natural ventilation of theindoor space 71 . Therefore, the comfort and energy saving of theindoor space 71 can be further improved.
