背景技术Background technique
空调器在夏季用于制冷或者除湿，在冬季用于制热，能够调节室内温度，使得空调房间能够达到冬暖夏凉的舒适环境。在空调器保证空调房间舒适性的同时，空调生产厂家一致在致力于研发新的技术方案，使得空调器的能耗降低，提高空调器的使用效率。The air conditioner is used for cooling or dehumidification in summer, and for heating in winter. It can adjust the indoor temperature, so that the air-conditioned room can achieve a comfortable environment that is warm in winter and cool in summer. While the air conditioner ensures the comfort of the air-conditioned room, the air-conditioner manufacturers are unanimously committed to research and development of new technical solutions to reduce the energy consumption of the air conditioner and improve the use efficiency of the air conditioner.
如申请人日前所公开的中国发明专利申请《空调节能控制方法、控制装置及空调》，申请号2016102516288中公开了一种技术方案：“空调器运行，获取实时室内环境温度和设定目标温度，计算实时室内环境温度与设定目标温度之间的温差作为实时温差，根据实时温差进行PID运算，获得第一频率；同时，根据已知的温差与风速的对应关系获取与实时温差对应的风速，作为实时风速；根据已知的风速与频率的对应关系获取与实时风速对应的频率，作为第二频率，选择第一频率与第二频率中较小值作为目标频率，根据目标频率控制空调的压缩机运行。”在该申请文件的说明书中进一步记载了“根据已知的温差与风速的对应关系获取与实时温差对应的风速，作为实时风速。…在空调主控板的存储器中预先存储有温差与风速的对应关系。对应与不同的温差，对应有不完全相同或完全不相同的风速。”For example, the Chinese invention patent application "Air Conditioner Energy Saving Control Method, Control Device and Air Conditioner" published by the applicant recently, the application number 2016102516288 discloses a technical solution: "The air conditioner is running, and the real-time indoor ambient temperature and the set target temperature are obtained. Calculate the temperature difference between the real-time indoor ambient temperature and the set target temperature as the real-time temperature difference, perform PID calculation according to the real-time temperature difference, and obtain the first frequency; at the same time, obtain the wind speed corresponding to the real-time temperature difference according to the known correspondence between the temperature difference and the wind speed, As the real-time wind speed; obtain the frequency corresponding to the real-time wind speed according to the known correspondence between wind speed and frequency, as the second frequency, select the smaller value of the first frequency and the second frequency as the target frequency, and control the compression of the air conditioner according to the target frequency machine operation.” In the specification of the application document, it is further recorded that “According to the known correspondence between temperature difference and wind speed, the wind speed corresponding to the real-time temperature difference is obtained as the real-time wind speed. …The temperature difference is pre-stored in the memory of the air-conditioning main control board.

但是，用户在实际使用的过程，会主动干预风速以得到快速调温的体验。以制冷工况为例，用户感受温度较高，会强制调节空调器的风速。实时风速发生变化后，根据已知的风速获取的第二频率也会发生变化，通常会导致压缩机的实际运行频率上升，送风温度较低，这一方面会提高空调器的能耗，另一方面会影响用户的实际体验。However, during actual use, the user will actively intervene in the wind speed to obtain a fast temperature adjustment experience. Taking the cooling working condition as an example, the user feels the temperature is high and will forcefully adjust the wind speed of the air conditioner. After the real-time wind speed changes, the second frequency obtained according to the known wind speed will also change, which usually leads to an increase in the actual operating frequency of the compressor and lower air supply temperature, which will increase the energy consumption of the air conditioner on the one hand, and on the other hand On the one hand, it will affect the actual experience of users.

下面参照附图对本发明所提出的空调器控制方法及空调器进行描述。The air conditioner control method and the air conditioner proposed by the present invention will be described below with reference to the accompanying drawings.
如图1所示，本实施例所公开的空调器控制方法通过以下步骤实现：As shown in Figure 1, the air conditioner control method disclosed in this embodiment is implemented through the following steps:
步骤S101, 空调器开机。Step S101, the air conditioner is turned on.
步骤S102, 空调器根据模式设定信号工作在制冷模式，压缩机低频启动。Step S102, the air conditioner works in the cooling mode according to the mode setting signal, and the compressor starts at low frequency.
步骤S103，获取室内环境温度和设定目标温度，计算实时室内环境温度与设定目标温度之间的温差，作为实时温差。Step S103, acquiring the indoor ambient temperature and the set target temperature, and calculating the temperature difference between the real-time indoor ambient temperature and the set target temperature as the real-time temperature difference.
空调器开机运行后，用户可以通过终端设备设定空调器的工作模式，以及空调房间的设定温度。在本实施例中，终端设备可以是遥控器、以手机或平板电脑为代表的智能终端，或者设置在空调器室内机上的按键面板，还可以是其它现有技术中已公开的终端设备，在此不做限定。室内环境温度可以通过设置在空调器回风口上的温度传感器检测得到，也可以通过设置在空调房间内其它联动空气调节设备上的温度传感器，或者独立设置在空调房间中的温度传感器得到。空调器的控制器在接收到设定温度后，根据实时的室内环境温度计算二者之间的温差作为实时温差。After the air conditioner is turned on and running, the user can set the working mode of the air conditioner and the set temperature of the air-conditioned room through the terminal device. In this embodiment, the terminal device may be a remote control, an intelligent terminal represented by a mobile phone or a tablet computer, or a button panel set on an indoor unit of an air conditioner, or other terminal devices disclosed in the prior art. This is not limited. The indoor ambient temperature can be detected by the temperature sensor installed on the return air outlet of the air conditioner, or by the temperature sensor installed on other linked air-conditioning equipment in the air-conditioned room, or the temperature sensor independently installed in the air-conditioned room. After receiving the set temperature, the controller of the air conditioner calculates the temperature difference between them according to the real-time indoor ambient temperature as the real-time temperature difference.
步骤S104，根据步骤S103得到的实时温差，以消除所述实时温差为控制目标进行PID运算，获得控制压缩机运行的第一频率。Step S104, according to the real-time temperature difference obtained in step S103, the PID calculation is performed with eliminating the real-time temperature difference as the control target, and the first frequency for controlling the operation of the compressor is obtained.
步骤S105,类似的，根据已知的温差与风速的对应关系获取实时温差对应的风速，作为实时风速，并控制空调器室内机中的风机按照实时风速运行并保持。Step S105, similarly, obtain the wind speed corresponding to the real-time temperature difference according to the known correspondence between the temperature difference and the wind speed as the real-time wind speed, and control the fan in the indoor unit of the air conditioner to run and maintain the real-time wind speed.
步骤S106，根据已知的风速与频率的对应关系获取与实时风速对应的频率作为第二频率。在空调器的控制器中预先存储有风速和频率的对应关系。对于不同的风速，对应有不同的频率。在步骤S105中获得实时风速后，从风速与频率的对应关系中先查找到实时风速所对应的风速值，然后获取该实时风速对应的频率，并将该频率作为第二频率。Step S106, acquiring a frequency corresponding to the real-time wind speed as a second frequency according to the known correspondence between wind speed and frequency. The corresponding relationship between wind speed and frequency is pre-stored in the controller of the air conditioner. For different wind speeds, there are different frequencies correspondingly. After the real-time wind speed is obtained in step S105, the wind speed value corresponding to the real-time wind speed is first found from the correspondence between wind speed and frequency, and then the frequency corresponding to the real-time wind speed is obtained, and this frequency is used as the second frequency.
步骤S107,选择第一频率和第二频率之间的较小值作为目标频率，根据目标频率控制空调器压缩机的运行。Step S107, selecting a smaller value between the first frequency and the second frequency as the target frequency, and controlling the operation of the air conditioner compressor according to the target frequency.
在运行过程中，用户可能会主动干预制冷过程，可能性最大的即是调节风速。因此，与现有技术完全不同，如步骤S108所示，在根据目标频率控制空调器压缩机运行的过程中，主动检测是否接收到风速调节信号。风速调节信号同样可以是来自遥控器、以手机或者平板电脑为代表的智能终端，或者设置在空调器室内机上的按键面板。对于空调器控制器来说，风速调节信号构成一个外部中断，在接收到所述风速调节信号后，空调器控制器响应风速调节信号。风速调节信号可以是档位信号。During operation, the user may actively intervene in the refrigeration process, the most likely being to adjust the wind speed. Therefore, completely different from the prior art, as shown in step S108, during the process of controlling the operation of the air conditioner compressor according to the target frequency, it is actively detected whether the wind speed adjustment signal is received. The wind speed adjustment signal can also be from a remote controller, an intelligent terminal represented by a mobile phone or a tablet computer, or a button panel arranged on the indoor unit of the air conditioner. For the air conditioner controller, the wind speed adjustment signal constitutes an external interrupt, and after receiving the wind speed adjustment signal, the air conditioner controller responds to the wind speed adjustment signal. The wind speed adjustment signal may be a gear position signal.
如步骤S109所示，在接收到风速调节信号时，空调器控制器判定风速调节信号对应的目标风速值是否高于实时风速。如果目标风速值低于实时风速，空调器依旧选择第一频率和第二频率之间的较小值作为目标频率，并维持实时风速不变。As shown in step S109, when receiving the wind speed adjustment signal, the air conditioner controller determines whether the target wind speed value corresponding to the wind speed adjustment signal is higher than the real-time wind speed. If the target wind speed value is lower than the real-time wind speed, the air conditioner still selects a smaller value between the first frequency and the second frequency as the target frequency, and keeps the real-time wind speed unchanged.
如步骤S110所示，如果目标风速值高于实时风速，代表用户希望室内风机风速升高。空调器选择第一频率作为目标频率，根据第一频率控制压缩机运行。在本实施例中，第二频率是根据实时风速查表获得的，因此，采用第一频率作为目标频率，可以避免实时风速波动的情况下，第二频率发生波动，进而可以避免压缩机运行发生波动。As shown in step S110, if the target wind speed value is higher than the real-time wind speed, it means that the user wishes to increase the wind speed of the indoor fan. The air conditioner selects the first frequency as the target frequency, and controls the operation of the compressor according to the first frequency. In this embodiment, the second frequency is obtained according to the real-time wind speed look-up table. Therefore, using the first frequency as the target frequency can avoid fluctuations in the second frequency when the real-time wind speed fluctuates, thereby avoiding compressor operation. fluctuate.
步骤S111，空调器室内机风机执行风速调节信号对应的目标风速值，按照风速调节信号对应的目标风速值运行，满足用户提升风速的需求。Step S111 , the fan of the indoor unit of the air conditioner executes the target wind speed value corresponding to the wind speed adjustment signal, and operates according to the target wind speed value corresponding to the wind speed adjustment signal, so as to meet the user's demand for increasing the wind speed.
步骤S112，按照设定速率降低目标风速值。Step S112, reducing the target wind speed value according to the set rate.
步骤S113，直至实时温差为零。Step S113, until the real-time temperature difference is zero.
具体来说，当目标风速值高于实时风速时，即使压缩机频率保持不变，用户的体表温度也会相对以较快的速度下降，如果压缩机频率小幅度上升，则体表温度的下降会更明显，保持长时间的吹送状态容易造成用户不适甚至引发疾病。在本实施例中，在室内风机按照风速调节信号对应的目标风速值开始运行之后，控制器按照设定速率主动降低目标风速值，使得风速保持自目标风速值平缓下降的态势。这样，在调节过程的初始阶段，用户可以感受到高风带来的舒适感，使得体表温度以较快的速度下降，随着室内环境温度逐渐靠近设定温度，风速逐渐下降，用户不会感受到风速跃变，既提供了高风速带来的快感，也避免了长时间吹送带来的不适，具有更智能，用户体验更好的优点。Specifically, when the target wind speed value is higher than the real-time wind speed, even if the compressor frequency remains unchanged, the user's body surface temperature will drop relatively quickly. If the compressor frequency increases slightly, the user's body surface temperature will The drop will be more obvious, and maintaining the blowing state for a long time may easily cause user discomfort or even cause disease. In this embodiment, after the indoor fan starts to operate according to the target wind speed value corresponding to the wind speed adjustment signal, the controller actively reduces the target wind speed value according to the set rate, so that the wind speed maintains a trend of gradually decreasing from the target wind speed value. In this way, in the initial stage of the adjustment process, the user can feel the comfort brought by the high wind, which makes the body surface temperature drop at a faster rate. As the indoor ambient temperature gradually approaches the set temperature, the wind speed gradually decreases, and the user will not Feel the sudden change of wind speed, which not only provides the pleasure brought by high wind speed, but also avoids the discomfort caused by long-term blowing, and has the advantages of being smarter and better user experience.
具体来说，降低目标风速值的设定速率并不是固定不变的。参见图2为本发明所公开的空调器控制方法第一种优选实施例的流程图。Specifically, the set rate of reducing the target wind speed value is not fixed. Referring to FIG. 2 , it is a flow chart of the first preferred embodiment of the air conditioner control method disclosed in the present invention.
在室内风机按照风速调节信号对应的目标风速值开始运行时，空调控制器判定实时温差所属的设定区间。理论上，当实时温差较高时，根据现有技术生成的实时风速相对较高，大于实时风速的目标风速值更高，降风速控制时的基数和调节范围都更大，当实时温差较小时，根据现有技术生成的实时风速相对较小，降风速控制时的基数和调节范围都更小，过快的降低风速会导致出风过低，降低空调的使用舒适度。When the indoor fan starts to run according to the target wind speed value corresponding to the wind speed adjustment signal, the air conditioner controller determines the set interval to which the real-time temperature difference belongs. Theoretically, when the real-time temperature difference is high, the real-time wind speed generated according to the existing technology is relatively high, and the target wind speed value greater than the real-time wind speed is higher, and the base number and adjustment range of the wind speed reduction control are larger. When the real-time temperature difference is small , the real-time wind speed generated according to the prior art is relatively small, and the base number and adjustment range of the wind speed reduction control are both smaller. Too fast reduction of the wind speed will lead to too low air output and reduce the comfort of the air conditioner.
所以，降低风速时，首先如步骤S213所示，判定实时温差所属的设定区间；然后如步骤S214所示，按照所属数值区间对应的设定速率降低目标风速，如果实时温差属于第一设定区间，则按照第一设定速率降低目标风速值；如果实时温差属于第二设定区间，则按照第二设定速率降低目标风速值，如果实时温差属于第三设定区间，则按照第三设定速率降低目标风速值。其中第一设定区间、第二设定区间和第三设定区间的上限阈值依次递减，第一设定速率、第二设定速率和第三设定速率依次递减。一组可选的取值为，第一设定区间为[3℃，2℃)，第二设定区间为[2℃，1℃)，第三设定区间为[1℃，0℃)。当实时温差属于第一设定区间时，第一设定速率为50r/min, 当实时温差属于第二设定区间时，第二设定速率为40r/min，当实时温差属于第三设定区间时，第三设定速率为30r/min。Therefore, when reducing the wind speed, first, as shown in step S213, determine the setting interval to which the real-time temperature difference belongs; If the real-time temperature difference belongs to the second setting interval, then reduce the target wind speed value at the second setting rate; if the real-time temperature difference belongs to the third setting interval, then reduce the target wind speed value at the third setting interval. Set the rate to reduce the target wind speed value. The upper thresholds of the first setting interval, the second setting interval and the third setting interval decrease successively, and the first setting rate, the second setting rate and the third setting rate decrease successively. A set of optional values, the first setting interval is [3°C, 2°C), the second setting interval is [2°C, 1°C), the third setting interval is [1°C, 0°C) . When the real-time temperature difference belongs to the first setting interval, the first setting speed is 50r/min; when the real-time temperature difference belongs to the second setting interval, the second setting speed is 40r/min; when the real-time temperature difference belongs to the third setting In interval, the third setting speed is 30r/min.
为了使得用户几乎感受不到风速的变化，优选的，设定第一设定区间、第二设定区间和第三设定区间的取值范围依次递增，这样风速较快下降的时间比较短，较慢下降的时间比较长，用户的实际感受差异性更小。如以上举例，可以选定第一设定区间为[3℃，2.5℃), 第二设定区间为[2.5℃，1.5℃), 第三设定区间为[1.5℃，0℃)。In order to make the user hardly feel the change of the wind speed, preferably, the value ranges of the first setting interval, the second setting interval and the third setting interval are set to increase sequentially, so that the time for the wind speed to drop quickly is relatively short. The slower decline takes longer, and the difference in the user's actual experience is smaller. As the example above, you can select the first setting interval as [3°C, 2.5°C), the second setting interval as [2.5°C, 1.5°C), and the third setting interval as [1.5°C, 0°C).
在实时风速发生变化的条件下，为了兼顾空调器的节能性，如步骤S315所示，每一个所述降速周期结束时，根据降速周期结束时的实时风速以及一致的风速与频率的对应关系获取第三频率。定义目标风速值为R1，则在一个降速周期结束时，即执行目标风速值R1一分钟，或者若干个一分钟之后，通过查表的方式获取第三频率，并去第一频率和第三频率中的较小值作为目标频率，控制空调器的运行，以同时达到节能的效果。Under the condition that the real-time wind speed changes, in order to take into account the energy-saving performance of the air conditioner, as shown in step S315, at the end of each deceleration cycle, according to the real-time wind speed at the end of the deceleration cycle and the corresponding correspondence between the wind speed and the frequency Relationships acquire a third frequency. Define the target wind speed value R1, then at the end of a deceleration period, that is, execute the target wind speed value R1 for one minute, or after several one minutes, obtain the third frequency by looking up the table, and go to the first frequency and the third frequency. The smaller value in the frequency is used as the target frequency to control the operation of the air conditioner, so as to achieve the effect of energy saving at the same time.
参见图3所示为本发明所公开的空调器控制方法第二种优选实施例的流程图。还可以通过温冷感的检测结果确定。Referring to FIG. 3 , it is a flow chart of the second preferred embodiment of the air conditioner control method disclosed in the present invention. It can also be determined by the detection results of the sense of warmth and coldness.
如步骤S312，采集温冷感传感器的实时检测信号。In step S312, the real-time detection signal of the temperature sensor is collected.
步骤S313，判断温冷感传感器的实时检测信号的温冷感等级。在夏季制冷状态，温冷感传感器会输出很热、热和舒适几个等级。Step S313 , judging the thermal sensation level of the real-time detection signal of the thermal sensation sensor. In the cooling state in summer, the temperature and cold sensor will output several levels of very hot, hot and comfortable.
步骤S314, 按照温冷感等级对应的设定速率降低目标风速。Step S314, reducing the target wind speed according to the set rate corresponding to the level of thermal sensation.
如果温冷感等级为很热，则按照第一速率降低目标风速值。如果温冷感等级为热，则按照第二速率降低目标风速值。如果温冷感等级为舒适，则按照第三设定速率降低目标风速值。其中，第一设定速率、第二设定速率和第三设定速率依次递增。这样，当用户实际体验较热时，以较慢的速度降低目标风速，风速较高的时间保持的较长，当用户实际体验不那么热时，以较快的速度降低目标风速，避免造成用户感觉不适。如果用户感受舒适，则保持风速不变，考虑到空调器的能耗，以第三设定速率匀速降低压缩机运行频率，优选的第三设定速率为20Hz/40s。直至实时温差等于0，退出上述程序。If the sense of temperature and cooling level is very hot, then reduce the target wind speed value according to the first rate. If the thermal sensation level is hot, the target wind speed value is decreased according to the second rate. If the temperature level is comfortable, the target wind speed value is reduced according to the third setting rate. Wherein, the first set rate, the second set rate and the third set rate increase sequentially. In this way, when the user's actual experience is hot, the target wind speed will be reduced at a slower speed, and the time when the wind speed is higher will be maintained for a longer time; Feeling unwell. If the user feels comfortable, keep the wind speed constant, and consider the energy consumption of the air conditioner, reduce the operating frequency of the compressor at a constant speed at a third set rate, and the preferred third set rate is 20Hz/40s. Until the real-time temperature difference is equal to 0, exit the above program.
在实时风速发生变化的条件下，为了兼顾空调器的节能性，如步骤S215所示，每一个所述降速周期结束时，根据降速周期结束时的实时风速以及一致的风速与频率的对应关系获取第三频率。定义目标风速值为R1，则在一个降速周期结束时，即执行目标风速值R1一分钟，或者若干个一分钟之后，通过查表的方式获取第三频率，并去第一频率和第三频率中的较小值作为目标频率，控制空调器的运行，以同时达到节能的效果。Under the condition that the real-time wind speed changes, in order to take into account the energy-saving performance of the air conditioner, as shown in step S215, at the end of each deceleration cycle, according to the real-time wind speed at the end of the deceleration cycle and the corresponding correspondence between the wind speed and the frequency Relationships acquire a third frequency. Define the target wind speed value R1, then at the end of a deceleration period, that is, execute the target wind speed value R1 for one minute, or after several one minutes, obtain the third frequency by looking up the table, and go to the first frequency and the third frequency. The smaller value in the frequency is used as the target frequency to control the operation of the air conditioner, so as to achieve the effect of energy saving at the same time.
对于某些具有混风效果的空调器来说，则采用如图4所示的方式降低目标风速值。首先，如步骤S412所示，判定空调器中是否设置有两台风机。如果是，则如步骤S413和步骤S414所示，其中一台风机执行风速调节信号对应的目标风速值，另一台风机按照设定风速运行。设定风速小于所述目标风速值，优选与目标风速值呈比例关系，如为目标风速的80%。两台风机可以形成混风效果，直至实时温差等于0，退出程序。For some air conditioners with wind mixing effect, the target wind speed value is lowered in the manner shown in FIG. 4 . First, as shown in step S412, it is determined whether there are two blowers installed in the air conditioner. If so, as shown in steps S413 and S414, one of the fans executes the target wind speed value corresponding to the wind speed adjustment signal, and the other fan operates at the set wind speed. The set wind speed is less than the target wind speed value, preferably proportional to the target wind speed value, such as 80% of the target wind speed value. The two fans can form a mixed air effect until the real-time temperature difference is equal to 0 and exit the program.
通过本发明上述实施例所提供的空调器控制方法，当用户强制改变空调器程序设定的实时风速，进一步引起空调器压缩机频率变化的情况下，空调器可以根据表征制冷系统运行状况的状态参数，如实际温差，或者表征室内舒适性的参数，如温冷感等级等，调用合理的设定速率降低目标风速值，用户既可以感受到高风带来的舒适感，使得体表温度以较快的速度下降，同时又可以避免长时间高风运行带来的不适感，在降风速的过程中，用户不会感受到风速跃变。Through the air conditioner control method provided by the above embodiments of the present invention, when the user forcibly changes the real-time wind speed set by the air conditioner program, which further causes the frequency of the air conditioner compressor to change, the air conditioner can Parameters, such as the actual temperature difference, or parameters that represent indoor comfort, such as the level of temperature and coldness, call a reasonable setting rate to reduce the target wind speed value, and the user can feel the comfort brought by the high wind, making the body surface temperature at The speed drops faster, and at the same time, it can avoid the discomfort caused by long-term high-wind operation. During the process of reducing the wind speed, the user will not feel the sudden change of the wind speed.
