背景技术Background technique
随着经济的发展我国提升人们生产水平的需求越来越高，高品质农副产品需求愈发旺盛，催生出农业生产现代化转型，其中农副产品冷藏存储为重要一环，农副产品冷藏仓库正大规模建设。With the development of the economy, my country's demand for improving people's production levels is getting higher and higher, and the demand for high-quality agricultural and sideline products has become increasingly strong, giving rise to the modernization of agricultural production. Among them, refrigerated storage of agricultural and sideline products is an important part, and refrigerated warehouses for agricultural and sideline products are being built on a large scale. .
目前，冷藏仓库即冷库包括：室外侧冷凝机组与室内侧冷风机，并且，这两个独立的设备仅靠冷媒联机管进行连接。这样，室外侧冷凝机组无法及时获取冷库实时库温参数，仅靠出厂或施工现场设置的默认目标蒸发(温度)压力，来控制冷凝机组中压缩机的启停。但是，冷库在实际使用过程中存在的多变情况，包括：存放货物种类不固定，往往随农业生产季节存较大变化；冷库存货量/出货周期不固定，仓储负荷不稳定；以及库建设施工标准及选材非统一标准，往往存在不同的偏差，整体负荷漏热不同等等，并且，冷库的使用者多为农业生产从业人员，大多欠缺冷库运维专业经验，对冷凝机组设备调试及参数设置操作经验欠缺。At present, the refrigerated warehouse, that is, the cold storage, includes: an outdoor condensing unit and an indoor air cooler, and these two independent devices are connected only by the refrigerant connection pipe. In this way, the outdoor condensing unit cannot obtain the real-time temperature parameters of the cold storage in time, and only relies on the default target evaporation (temperature) pressure set at the factory or at the construction site to control the start and stop of the compressor in the condensing unit. However, there are many changes in the actual use of cold storage, including: the types of goods stored are not fixed, and often vary greatly with the agricultural production season; the volume/shipment cycle of cold storage is not fixed, and the storage load is unstable; and warehouse construction Construction standards and material selection are not unified standards, and there are often different deviations, different overall load heat leakage, etc. Moreover, most users of cold storage are agricultural production practitioners, and most of them lack professional experience in cold storage operation and maintenance. They are not familiar with the equipment debugging and parameters of the condensing unit. Lack of experience in setting up operations.
鉴于上述多变情况，单独设置一个目标蒸发(温度)压力来控制冷凝机组运行方式，会产生上述的一些冷凝机组与冷库库温响应不及时性问题，更有甚者达不到目标库温或降温时间过长，导致仓储货物品质恶化问题。In view of the above-mentioned changeable situation, setting a target evaporation (temperature) pressure alone to control the operation mode of the condensing unit will cause some of the above-mentioned problems of untimely response of the condensing unit and the cold storage temperature, and even worse, the target storage temperature or If the cooling time is too long, the quality of warehoused goods will deteriorate.

本公开实施例提供的用于冷库冷凝机组控制的方法、装置、设备和存储介质，可以实现以下技术效果：The methods, devices, equipment and storage media for controlling cold storage condensing units provided by embodiments of the present disclosure can achieve the following technical effects:
在冷凝机组的当前蒸发压力值处于当前目标蒸发压力值的设定范围内的情况，若当前冷库温度未到要求，电磁阀仍处于吸合状态，启动计时，且持续吸合时间大于或等于设定时间时，冷凝机组中压缩机仍然需要运行，且提升压缩机的当前运行频率，直至当前冷库温度达到要求，才断开电磁阀。这样，随着压缩机频率的升高，蒸发压力值会逐步降低，冷风机换热温差加大，冷量输出加大，库温逐步降低，会加快冷库温度达到要求的速度，减少冷库温度达不到目标库温或降温时间过长，而导致仓储货物品质恶化问题出现的几率，提高了冷库库温的稳定性。When the current evaporation pressure value of the condensing unit is within the setting range of the current target evaporation pressure value, if the current cold storage temperature does not reach the requirement, the solenoid valve is still in the closing state, starts the timing, and the continuous closing time is greater than or equal to the set value. When the time is set, the compressor in the condensing unit still needs to run, and the current operating frequency of the compressor is increased. The solenoid valve is not turned off until the current cold storage temperature reaches the requirement. In this way, as the frequency of the compressor increases, the evaporation pressure value will gradually decrease, the heat exchange temperature difference of the air cooler will increase, the cooling output will increase, and the storage temperature will gradually decrease, which will speed up the temperature of the cold storage to reach the required speed and reduce the temperature of the cold storage to the required level. If the target storage temperature is not reached or the cooling time is too long, the quality of the stored goods will deteriorate, which improves the stability of the cold storage temperature.

本公开实施例中，室外测的冷凝机组，不在仅仅靠目标蒸发压力值，来控制冷凝机组中压缩机的运行，而是，还可根据由库温控制的电磁阀的状态，来控制冷凝机组中压缩机的运行，这样，会加快冷库温度达到要求的速度，减少冷库温度达不到目标库温或降温时间过长，而导致仓储货物品质恶化问题出现的几率，提高了冷库库温的稳定性。In the embodiment of the present disclosure, the condensing unit measured outdoors no longer relies solely on the target evaporation pressure value to control the operation of the compressor in the condensing unit. Instead, the condensing unit can also be controlled based on the state of the solenoid valve controlled by the storage temperature. This will speed up the speed at which the cold storage temperature reaches the required temperature, reduce the chance that the cold storage temperature will not reach the target temperature or the cooling time will be too long, resulting in deterioration of the quality of the stored goods, and improve the stability of the cold storage temperature. sex.
其中，冷库包括：位于室内侧的冷风机，以及位于室外测的冷凝机组，两者之间通过气管以及液管连接，其中，连接冷风机与冷凝机组的内外联机液管的管路中配置了电磁阀。Among them, the cold storage includes: an air cooler located indoors and a condensing unit located outdoors. The two are connected through air pipes and liquid pipes. Among them, the internal and external liquid pipes connecting the air cooler and the condensing unit are equipped with The electromagnetic valve.
图1是本公开实施例提供的一种用于冷库的结构示意图。如图1所示，冷库包括：位于室内侧的冷风机，以及位于室外测的冷凝机组，其中，在室内侧冷风机可包括：冷风机、冷风机控制装置、位于液管上的热力膨胀阀、电磁阀；而室外测冷凝机组可包括：压缩机、冷凝器总成、高压储液器、冷凝机组控制装置、以及位于液管上的液管截止阀、视液镜、干燥过滤器，以及位于气管上的气管截止阀和低压传感器。Figure 1 is a schematic structural diagram of a cold storage provided by an embodiment of the present disclosure. As shown in Figure 1, the cold storage includes: an air cooler located on the indoor side, and a condensing unit located outdoors. The air cooler on the indoor side may include: an air cooler, an air cooler control device, and a thermal expansion valve located on the liquid pipe. , solenoid valve; while the outdoor measuring condensing unit can include: compressor, condenser assembly, high-pressure liquid reservoir, condensing unit control device, liquid pipe stop valve located on the liquid pipe, sight glass, dry filter, and Tracheal shutoff valve and low pressure sensor located on the trachea.
当然，冷风机控制装置可分别与冷风机、膨胀阀、电磁阀电控连接，并且，冷凝机组控制装置可分布与压缩机、冷凝器总成、液管截止阀、气管截止阀和低压传感器等电控连接。并且，在本公开实施例中，冷凝机组控制装置还可与冷风机控制装置之间进行通讯连接。Of course, the air cooler control device can be electrically connected to the air cooler, expansion valve, and solenoid valve respectively, and the condensing unit control device can be distributed with the compressor, condenser assembly, liquid pipe stop valve, air pipe stop valve, and low pressure sensor, etc. Electrical control connection. Moreover, in the embodiment of the present disclosure, the condensing unit control device can also communicate with the air cooler control device.
这样，低压传感器可实时检测整套冷凝机组的运行的实时蒸发压力值Ps，与目标蒸发压力值Ps0进行比较计算，控制压缩机升频或降频动作，使系统机组蒸发压力值处于Ps0-ΔPs≤Ps≤Ps0+ΔPs之间稳定运行。In this way, the low-pressure sensor can detect the real-time evaporation pressure value Ps of the entire condensing unit in real time, compare it with the target evaporation pressure value Ps0, and control the frequency increase or decrease of the compressor so that the evaporation pressure value of the system unit is at Ps0-ΔPs≤ Stable operation between Ps≤Ps0+ΔPs.
而室内冷库侧根据实际使用情况配置冷风机，根据冷库热负荷的大小，可配置一套或多套机组，一个冷凝主机配置一台冷风机组成成套制冷系统，如图1所示，其中内外联机液管管路上配置有热力膨胀阀，进行冷媒节流；热力膨胀阀前端设置有电磁阀，控制冷媒的通断。电磁阀受冷风机控制装置控制动作，当实时冷库温度T小于第一设定值(Ts-ΔT)时，则控制电磁阀关闭，即冷库内温度达到用户设定库温目标值，电磁阀关闭截断液管供液；同时电磁阀供电断开信号，即电磁阀断开指令，可由冷风机控制装置传至外侧冷凝机组控制装置，此时，冷凝机组控制装置可控制压缩机停止运行；当实时冷库温度T回升至≥第二设定值(Ts+ΔT)后，冷风机控制装置控制电磁阀重新上电，打开电磁阀恢复液管制冷剂通路状态，即发送电磁阀吸合指令，这样，室外侧冷凝机组控制装置收到电磁阀吸合指令后控制压缩启动，开启冷库制冷模式。其中，Ts为冷库控制柜用户设定的目标控温温度，用户可根据不同的仓储物料种类进行设定；而ΔT可为冷库控制柜控温精度值，用户根据冷库内物品不同可进行调整。The indoor cold storage side is equipped with an air cooler according to the actual usage. According to the heat load of the cold storage, one or more sets of units can be configured. A condensing host is equipped with an air cooler to form a complete refrigeration system, as shown in Figure 1, in which the internal and external units are connected A thermal expansion valve is installed on the liquid pipe to throttle the refrigerant; a solenoid valve is installed at the front of the thermal expansion valve to control the on and off of the refrigerant. The solenoid valve is controlled by the cooling fan control device. When the real-time cold storage temperature T is less than the first set value (Ts-ΔT), the solenoid valve is controlled to close. That is, the temperature in the cold storage reaches the user-set target temperature, and the solenoid valve closes. Cut off the liquid supply of the liquid pipe; at the same time, the solenoid valve power supply disconnection signal, that is, the solenoid valve disconnection command, can be transmitted from the air cooler control device to the outer condensation unit control device. At this time, the condensation unit control device can control the compressor to stop running; when real-time After the cold storage temperature T rises to ≥ the second set value (Ts+ΔT), the air cooler control device controls the solenoid valve to re-power on, opens the solenoid valve to restore the liquid pipe refrigerant passage state, that is, sends the solenoid valve pull-in command, so that, After receiving the solenoid valve closing command, the control device of the outdoor condensing unit controls the compression start and turns on the cold storage refrigeration mode. Among them, Ts is the target temperature control temperature set by the user of the cold storage control cabinet, which can be set according to different types of storage materials; and ΔT can be the temperature control accuracy value of the cold storage control cabinet, which can be adjusted by the user according to the different items in the cold storage.
并且，本公开实施例中，实时获取的当前蒸发压力值处于设定范围内时，即Ps0-ΔPs≤Ps≤Ps0+ΔPs，且电磁阀仍处于吸合状态时，表明当前冷库温度T还大于或等于第一设定温度值，此时，若控制压缩机频率不变，那么冷库温度还比较高，存在达不到目标库温或降温时间过长的问题，因此，本公开实施例中，此时，可启动计时，记录电磁阀对应的持续吸合时间，在记录的当前持续吸合时间大于或等于设定时间的情况下，提升压缩机的当前运行频率，直至接收到冷风机在确定当前冷库温度小于第一设定温度的情况下发送的电磁阀断开指令。Moreover, in the embodiment of the present disclosure, when the current evaporation pressure value obtained in real time is within the set range, that is, Ps0-ΔPs≤Ps≤Ps0+ΔPs, and the solenoid valve is still in the pull-in state, it indicates that the current cold storage temperature T is still greater than Or equal to the first set temperature value. At this time, if the frequency of the control compressor remains unchanged, the temperature of the cold storage is still relatively high, and there is a problem that the target storage temperature cannot be reached or the cooling time is too long. Therefore, in the embodiment of the present disclosure, At this time, the timer can be started to record the continuous suction time corresponding to the solenoid valve. If the recorded current continuous suction time is greater than or equal to the set time, the current operating frequency of the compressor will be increased until it receives the confirmation signal from the air cooler. The solenoid valve disconnect command is sent when the current cold storage temperature is lower than the first set temperature.
例如：根据2Hz/s的速度，提升压缩机的当前运行频率，随着压缩机频率的升高，系统低压Ps会逐步降低，冷风机换热温差加大，冷量输出加大，库温逐步降低，这样，当前冷库温度小于第一设定温度(Ts-ΔT)时，冷库库温达到设定目标值，电磁阀关闭，从而，冷凝机组控制装置接收到电磁阀断开指令，从而，不用继续提升压缩机的当前运行频率。这样，提高了冷库制冷的效率，也提高了冷库库温的稳定性。当然，提升压缩机的当前运行频率的方式还有很多种，包括：按照设定比例值进行压缩机运行频率的提高，例如：按照0.3％、0.5％、1％等等的比例值进行压缩机运行频率的提高。For example: According to the speed of 2Hz/s, increase the current operating frequency of the compressor. As the compressor frequency increases, the system low pressure Ps will gradually decrease, the heat exchange temperature difference of the air cooler will increase, the cooling capacity output will increase, and the storage temperature will gradually decrease. Decrease, in this way, when the current cold storage temperature is less than the first set temperature (Ts-ΔT), the cold storage temperature reaches the set target value, the solenoid valve is closed, and the condensing unit control device receives the solenoid valve disconnection command, thus, no need Continue to increase the current operating frequency of the compressor. In this way, the refrigeration efficiency of the cold storage is improved, and the stability of the cold storage temperature is also improved. Of course, there are many ways to increase the current operating frequency of the compressor, including: increasing the operating frequency of the compressor according to the set proportion value, for example: increasing the compressor operating frequency according to the proportion value of 0.3%, 0.5%, 1%, etc. Increase in operating frequency.
当然，在接收到电磁阀断开的断开指令的情况下，可控制压缩机处于关闭状态，并且，由于电磁阀关闭，处于断开状态，因此，可关闭计时，将记录的当前持续吸合时间清零。Of course, when receiving a disconnection command to disconnect the solenoid valve, the compressor can be controlled to be in a closed state, and since the solenoid valve is closed and in a disconnected state, the timing can be turned off and the recorded current continuous closing Time cleared.
本公开实施例中，目标蒸发压力值是可以进行自动修正和更新的，这样，无需专业的冷库从业人员，即可实现冷凝机组设备的自动调试以及参数设置，进一步扩展了冷库应用场景，也节省了资本。因此，目标蒸发压力值的修正更新过程可包括：在接收到电磁阀断开的断开指令的情况下，获取冷凝机组的第一蒸发压力值并记录；在记录的第一蒸发压力值的个数等于设定个数的情况下，得到设定个数的第一蒸发压力值的平均蒸发压力值；将当前目标蒸发压力值替换为平均蒸发压力值。In the embodiment of the present disclosure, the target evaporation pressure value can be automatically corrected and updated. In this way, the automatic debugging and parameter setting of the condensing unit equipment can be realized without the need for professional cold storage practitioners, which further expands the application scenarios of cold storage and saves money. capital. Therefore, the correction and update process of the target evaporation pressure value may include: upon receiving a disconnection instruction to disconnect the solenoid valve, obtain the first evaporation pressure value of the condensing unit and record it; When the number is equal to the set number, the average evaporation pressure value of the set number of first evaporation pressure values is obtained; the current target evaporation pressure value is replaced by the average evaporation pressure value.
例如：在接收到电磁阀断开的断开指令的情况下，获取并记录了第一蒸发压力值Ps，并且，查看记录的第一蒸发压力值的个数，若有5个，则可将记录的5个第一蒸发压力值进行相加并求平均，得到平均蒸发压力值Psm，然后，当前目标蒸发压力值替换为平均蒸发压力值Psm，这样，修正的冷凝机组将根据平均蒸发压力值Psm进行压缩机评论控制，使得系统机组蒸发压力只处于(Psm-ΔPs)≤Ps≤(Psm+ΔPs)之间稳定运行。For example: when receiving the disconnection command to disconnect the solenoid valve, the first evaporation pressure value Ps is obtained and recorded, and the number of recorded first evaporation pressure values is checked. If there are 5, then the The five recorded first evaporation pressure values are added and averaged to obtain the average evaporation pressure value Psm. Then, the current target evaporation pressure value is replaced by the average evaporation pressure value Psm. In this way, the corrected condensing unit will be based on the average evaporation pressure value. Psm performs compressor evaluation control so that the evaporation pressure of the system unit can only operate stably between (Psm-ΔPs) ≤ Ps ≤ (Psm + ΔPs).
当然，将当前目标蒸发压力值替换为平均蒸发压力值之后，还包括：清空记录的第一蒸发压力值。这样，可来时新的一轮目标蒸发压力值的修正更新过程。Of course, after replacing the current target evaporation pressure value with the average evaporation pressure value, it also includes: clearing the recorded first evaporation pressure value. In this way, a new round of correction and update process of the target evaporation pressure value can be started.
压缩机停止运行后，冷库温度会有所上升，在当前冷库温度大于或等于第二设定温度(Ts+ΔT)的情况下，电磁阀会重新上电吸合，此时，冷凝机组控制模块可接收到电磁阀吸合指令，此时，需要启动压缩机，并制压缩机根据当前目标蒸发压力值进行运行，即在接收冷风机在确定当前冷库温度大于或等于第二设定温度的情况下发送的电磁阀吸合指令的情况下，控制压缩机根据当前目标蒸发压力值进行运行，其中，第二设定温度大于第一设定温度。After the compressor stops running, the temperature of the cold storage will rise. When the current cold storage temperature is greater than or equal to the second set temperature (Ts+ΔT), the solenoid valve will be powered on again. At this time, the condensing unit control module The solenoid valve pull-in command can be received. At this time, the compressor needs to be started and the compressor must be operated according to the current target evaporation pressure value, that is, when the receiving air cooler determines that the current cold storage temperature is greater than or equal to the second set temperature When the solenoid valve pull-in command is sent, the compressor is controlled to operate according to the current target evaporation pressure value, where the second set temperature is greater than the first set temperature.
可见，在冷库中，冷凝机组控制装置可根据室内侧冷库温度、室外侧冷凝机组的蒸发压力值，对冷凝机组进行控制。It can be seen that in the cold storage, the condensing unit control device can control the condensing unit according to the indoor side cold storage temperature and the evaporation pressure value of the outdoor side condensing unit.
图2是本公开实施例提供的一种用于冷库冷凝机组控制方法的流程示意图。可应用于上述的冷库的冷凝机组控制装置中，如图2所示，用于冷库冷凝机组控制的过程包括：FIG. 2 is a schematic flowchart of a control method for a cold storage condensing unit provided by an embodiment of the present disclosure. It can be applied to the above-mentioned cold storage condensation unit control device. As shown in Figure 2, the process for cold storage condensation unit control includes:
步骤201：在冷凝机组中压缩机处于运行状态的情况下，获取冷凝机组的当前蒸发压力值Ps。Step 201: When the compressor in the condensing unit is running, obtain the current evaporation pressure value Ps of the condensing unit.
在冷库的制冷过程中，冷凝机组中压缩机处于运行状态，可定时或实时获取冷凝机组的蒸发压力值，如图1所示，可通过配置在气路上的低压传感器，获取冷凝机组的蒸发压力值，每次获取的蒸发压力值即为当前蒸发压力值Ps。During the refrigeration process of the cold storage, the compressor in the condensing unit is running, and the evaporation pressure value of the condensing unit can be obtained regularly or in real time. As shown in Figure 1, the evaporation pressure of the condensing unit can be obtained through the low-pressure sensor configured on the gas line. value, the evaporation pressure value obtained each time is the current evaporation pressure value Ps.
步骤202：在当前蒸发压力值在与当前目标蒸发压力值的设定范围内的情况下，启动计时，记录电磁阀对应的持续吸合时间。Step 202: When the current evaporation pressure value is within the setting range of the current target evaporation pressure value, start the timing and record the corresponding continuous suction time of the solenoid valve.
当前目标蒸发压力值可为固定值，用户可预先配置，或者，在一些实施例中，当前目标蒸发压力值可在冷凝机组运行中进行更新，即冷凝机组启动运行时，当前目标蒸发压力值Ps0可设定值，随着冷凝机组运行，当前目标蒸发压力值可修改更新。The current target evaporation pressure value can be a fixed value, which can be pre-configured by the user, or, in some embodiments, the current target evaporation pressure value can be updated during the operation of the condensing unit, that is, when the condensing unit starts running, the current target evaporation pressure value Ps0 The value can be set. As the condensing unit operates, the current target evaporation pressure value can be modified and updated.
若当前蒸发压力值在与当前目标蒸发压力值的设定范围内时，即(Ps0-ΔPs)≤Ps≤(Ps0+ΔPs)，此时，冷凝机组控制器可已达到默认设定蒸发温度，但是，此时未接收到冷风机发送的电磁阀断开指令，即当前冷库温度还未到达设定目标温度，即当前冷库温度大于或等于第一设定温度，因此，电磁阀仍处于吸合状态，则可启动计时，记录电磁阀对应的持续吸合时间。If the current evaporation pressure value is within the setting range of the current target evaporation pressure value, that is, (Ps0-ΔPs) ≤ Ps ≤ (Ps0 + ΔPs), at this time, the condensing unit controller can reach the default set evaporation temperature. However, at this time, the solenoid valve disconnect command sent by the air cooler has not been received, that is, the current cold storage temperature has not reached the set target temperature, that is, the current cold storage temperature is greater than or equal to the first set temperature, therefore, the solenoid valve is still closed. status, you can start the timing and record the corresponding continuous closing time of the solenoid valve.
步骤203：在当前持续吸合时间大于或等于设定时间的情况下，提升压缩机的当前运行频率，直至接收到冷风机在确定当前冷库温度小于第一设定温度的情况下发送的电磁阀断开指令。Step 203: When the current continuous suction time is greater than or equal to the set time, increase the current operating frequency of the compressor until it receives the solenoid valve sent by the air cooler when it is determined that the current cold storage temperature is less than the first set temperature. Disconnect command.
记录了电磁阀对应的持续吸合时间，则可进行查看，若当前持续吸合时间大于或等于设定时间时，电磁阀仍处于吸合状态，则表明经过默认的设定时间这个t0时长后，冷库温度仍未达到设定库温值，说明冷凝机组对应的目标蒸发温度偏高，冷量输出不足，导致库温长时间降不下来，因此，需要提升压缩机运行频率。The continuous pull-in time corresponding to the solenoid valve is recorded and can be viewed. If the current continuous pull-in time is greater than or equal to the set time and the solenoid valve is still in the pull-in state, it means that after the default set time t0, , the cold storage temperature has not yet reached the set storage temperature value, indicating that the target evaporation temperature corresponding to the condensing unit is too high and the cooling capacity output is insufficient, resulting in the storage temperature not being able to drop for a long time. Therefore, the compressor operating frequency needs to be increased.
提升冷凝机组中压缩机运行频率的方式有多种，包括：根据设定速率，设定值，设定比例等方式提升压缩机运行频率，例如：按照1Hz/s、2Hz/s或5Hz/s的速度提升压缩机运行频率，或，安装0.3％、0.5％、或0.8％的增长比例，来提升压缩机运行频率。There are many ways to increase the operating frequency of the compressor in the condensing unit, including: increasing the operating frequency of the compressor according to the set speed, set value, set proportion, etc., for example: according to 1Hz/s, 2Hz/s or 5Hz/s Increase the compressor operating frequency by increasing the speed, or install an increase rate of 0.3%, 0.5%, or 0.8% to increase the compressor operating frequency.
随着压缩机频率的升高，冷凝机组的蒸发压力值Ps会逐步降低，冷风机换热温差加大，冷量输出加大，冷库温度逐步降低，当冷库温度T小于第一设定温度(Ts-ΔT)时，即冷库库温达到设定目标值，电磁阀关闭；即可接收到电磁阀断开指令。As the frequency of the compressor increases, the evaporation pressure value Ps of the condensing unit will gradually decrease, the heat exchange temperature difference of the air cooler increases, the cooling output increases, and the cold storage temperature gradually decreases. When the cold storage temperature T is less than the first set temperature ( When Ts-ΔT), that is, the cold storage temperature reaches the set target value, the solenoid valve is closed; the solenoid valve disconnection command is received.
可见，在冷凝机组的当前蒸发压力值处于当前目标蒸发压力值的设定范围内的情况，若经过设定时间，冷库温度仍未达到设定库温值，则可提升压缩机的当前运行频率，直至当前冷库温度达到要求，才断开电磁阀，这样，会加快冷库温度达到要求的速度，减少冷库温度达不到目标库温或降温时间过长，而导致仓储货物品质恶化问题出现的几率，提高了冷库库温的稳定性。It can be seen that when the current evaporation pressure value of the condensing unit is within the setting range of the current target evaporation pressure value, if the cold storage temperature has not reached the set storage temperature value after the set time, the current operating frequency of the compressor can be increased. , the solenoid valve will not be disconnected until the current cold storage temperature reaches the requirement. This will speed up the speed at which the cold storage temperature reaches the requirement, and reduce the chance that the cold storage temperature will not reach the target temperature or the cooling time will be too long, which will lead to the deterioration of the quality of the warehoused goods. , improving the stability of the cold storage temperature.
当然，在接收到电磁阀断开的断开指令的情况下，表明当前冷库温度已小于第一设定温度了，可停止冷凝机组的制冷运行了，因此，可控制压缩机处于关闭状态，并关闭计时，将记录的当前持续吸合时间清零。这样，可便于进行下一次的冷凝机组控制。Of course, when receiving a disconnection command to disconnect the solenoid valve, it indicates that the current cold storage temperature is lower than the first set temperature, and the refrigeration operation of the condensing unit can be stopped. Therefore, the compressor can be controlled to be in a closed state, and Turn off the timer and clear the recorded current continuous pickup time to zero. This will facilitate the next condensing unit control.
在步骤202中，描述了当前目标蒸发压力值可在冷凝机组运行中进行更新，在一些实施例中，当前目标蒸发压力值的修正过程可包括：在接收到电磁阀断开的断开指令的情况下，获取冷凝机组的第一蒸发压力值并记录；在记录的第一蒸发压力值的个数等于设定个数的情况下，得到设定个数的第一蒸发压力值的平均蒸发压力值；将当前目标蒸发压力值替换为平均蒸发压力值。In step 202, it is described that the current target evaporation pressure value can be updated during the operation of the condensing unit. In some embodiments, the correction process of the current target evaporation pressure value may include: upon receiving a disconnection instruction for the solenoid valve to disconnect. In this case, obtain the first evaporation pressure value of the condensing unit and record it; when the number of recorded first evaporation pressure values is equal to the set number, obtain the average evaporation pressure of the set number of first evaporation pressure values. value; replace the current target evaporation pressure value with the average evaporation pressure value.
接收到电磁阀断开的断开指令，记录此时的第一蒸发压力值Ps1；并查看记录的第一蒸发压力值Ps1的个数，若个数已经达到设定个数，例如：3个、4个或5个等等，则可求记录的这几个第一蒸发压力值的平均值，得到平均蒸发压力值Psm，然后，将当前目标蒸发压力值Ps0替换为平均蒸发压力值Psm。即下次进行冷凝机组控制的控制过程中，平均蒸发压力值Psm即为当前目标蒸发压力值Ps0。After receiving the disconnection command of the solenoid valve, record the first evaporation pressure value Ps1 at this time; and check the number of recorded first evaporation pressure values Ps1, if the number has reached the set number, for example: 3 , 4 or 5, etc., then the average of the recorded first evaporation pressure values can be obtained to obtain the average evaporation pressure value Psm, and then the current target evaporation pressure value Ps0 is replaced by the average evaporation pressure value Psm. That is, in the next control process of condensing unit control, the average evaporation pressure value Psm is the current target evaporation pressure value Ps0.
当然，将当前目标蒸发压力值替换为平均蒸发压力值之后，还需清空记录的第一蒸发压力值。这样，可进行下一次的当前目标蒸发压力值的修正和更新。Of course, after replacing the current target evaporation pressure value with the average evaporation pressure value, the recorded first evaporation pressure value also needs to be cleared. In this way, the next current target evaporation pressure value can be corrected and updated.
冷凝机组停止制冷运行了，冷库室内侧的冷库温度降回升，若当前冷库温度大于或等于第二设定温度(Ts+ΔT)时，室内侧的冷风机控制装置将会控制电磁阀吸合，即发送电磁阀吸合指令，这样，外侧冷凝机组将重新启动制冷运行，因此，在一些实施例中，在接收冷风机在确定当前冷库温度大于或等于第二设定温度的情况下发送的电磁阀吸合指令的情况下，控制压缩机启动运行，其中，第二设定温度大于第一设定温度。The condensing unit stops refrigeration operation, and the temperature of the cold storage inside the cold storage room drops and rises. If the current cold storage temperature is greater than or equal to the second set temperature (Ts+ΔT), the indoor air cooler control device will control the solenoid valve to close. That is, the solenoid valve pull-in command is sent, so that the outer condensing unit will restart the refrigeration operation. Therefore, in some embodiments, after receiving the electromagnetic valve sent by the cooling fan when it is determined that the current cold storage temperature is greater than or equal to the second set temperature, In the case of a valve closing command, the compressor is controlled to start running, where the second set temperature is greater than the first set temperature.
当然，在压缩机处于运行状态时，在当前蒸发压力值不在与当前目标蒸发压力值的设定范围内的情况下，可根据当前蒸发压力值以及当前目标蒸发压力值，控制压缩机的运行。这样，简单易操作，进一提高了制冷效率。Of course, when the compressor is in operation, if the current evaporation pressure value is not within the setting range of the current target evaporation pressure value, the operation of the compressor can be controlled based on the current evaporation pressure value and the current target evaporation pressure value. In this way, it is simple and easy to operate and further improves the refrigeration efficiency.

可见，本实施例中，室外测的冷凝机组，不在仅仅靠目标蒸发压力值，来控制冷凝机组中压缩机的运行，而是根据当前蒸发压力值、目标蒸发压力值以及当前冷库温度，来控制冷凝机组中压缩机的运行，这样，会加快冷库温度达到要求的速度，减少冷库温度达不到目标库温或降温时间过长，而导致仓储货物品质恶化问题出现的几率，提高了冷库库温的稳定性。并且，在冷凝机组运行过程中，还可自动修正和更新目标蒸发压力值，减少了冷库从业人员对冷库运行的影响，进一步提高了冷库控制的智能性。It can be seen that in this embodiment, the condensing unit measured outdoors no longer relies solely on the target evaporation pressure value to control the operation of the compressor in the condensing unit, but controls the operation based on the current evaporation pressure value, the target evaporation pressure value and the current cold storage temperature. The operation of the compressor in the condensing unit will speed up the speed at which the cold storage temperature reaches the required temperature, reduce the chance that the cold storage temperature will not reach the target temperature or the cooling time is too long, which will lead to the deterioration of the quality of the stored goods, and increase the cold storage temperature. stability. In addition, during the operation of the condensing unit, the target evaporation pressure value can be automatically corrected and updated, which reduces the impact of cold storage employees on the operation of the cold storage and further improves the intelligence of cold storage control.

下面将举例说明本发明实施例提供的用于冷库冷凝机组控制装置的控制过程。The following will illustrate the control process of the control device for the cold storage condensing unit provided by the embodiment of the present invention.
本实施例中，冷库可如图1所示，冷风机控制装置可分别与冷风机、膨胀阀、电磁阀电控连接，并且，冷凝机组控制装置可分布与压缩机、冷凝器总成、液管截止阀、气管截止阀和低压传感器等电控连接。并且，冷凝机组控制装置还可与冷风机控制装置之间进行通讯连接。In this embodiment, the cold storage can be as shown in Figure 1. The air cooler control device can be electrically connected to the air cooler, expansion valve, and solenoid valve respectively, and the condensing unit control device can be distributed with the compressor, condenser assembly, and liquid Pipe shut-off valve, tracheal shut-off valve and low-pressure sensor are electrically connected. Moreover, the condensing unit control device can also communicate with the air cooler control device.
图5是本公开实施例提供一种用于冷库冷凝机组控制装置的结构示意图。如图4所示，包括：获取模块410、计时模块420以及第一控制模块430；还可包括：关闭清零模块440、修正更新模块450、清空模块460、启动模块470以及第二控制模块480。Figure 5 is a schematic structural diagram of a control device for a cold storage condensing unit provided by an embodiment of the present disclosure. As shown in Figure 4, it includes: an acquisition module 410, a timing module 420 and a first control module 430; it may also include: a shutdown and clearing module 440, a correction and update module 450, a clearing module 460, a startup module 470 and a second control module 480. .
冷凝机组中压缩机处于运行状态时，获取模块410可，获取冷凝机组的当前蒸发压力值Ps，在(Ps0-ΔPs)≤Ps≤(Ps0+ΔPs)成立时，计时模块420可启动计时，记录电磁阀对应的持续吸合时间。When the compressor in the condensing unit is running, the acquisition module 410 can obtain the current evaporation pressure value Ps of the condensing unit. When (Ps0-ΔPs) ≤ Ps ≤ (Ps0 + ΔPs) is established, the timing module 420 can start timing and record The corresponding continuous closing time of the solenoid valve.
这样，若获取的当前持续吸合时间t≥t0，则第一控制模块430可根据2Hz/s的速度提升压缩机的当前运行运行频率。In this way, if the obtained current continuous suction time t ≥ t0, the first control module 430 can increase the current operating frequency of the compressor according to the speed of 2 Hz/s.
而接收到冷风机在确定当前冷库温度小于第一设定温度的情况下发送的电磁阀断开指令后，关闭清零模块440可控制压缩机处于关闭状态，并关闭计时，将记录的当前持续吸合时间清零。并且，修正更新模块450获取冷凝机组的第一蒸发压力值并记录，在记录的第一蒸发压力值的个数等于5个时，得到记录的5个第一蒸发压力值的平均蒸发压力值Psm，并将当前目标蒸发压力值Ps0替换为平均蒸发压力值Psm。而清空模块460即可清空记录的第一蒸发压力值。After receiving the solenoid valve disconnection command sent by the air cooler when it is determined that the current cold storage temperature is less than the first set temperature, the closing and clearing module 440 can control the compressor to be in a closed state and close the timing, and record the current continuous The pickup time is cleared. Furthermore, the correction and update module 450 obtains the first evaporation pressure value of the condensing unit and records it. When the number of recorded first evaporation pressure values is equal to 5, the average evaporation pressure value Psm of the recorded 5 first evaporation pressure values is obtained. , and replace the current target evaporation pressure value Ps0 with the average evaporation pressure value Psm. The clearing module 460 can clear the recorded first evaporation pressure value.
当然，接收冷风机在确定当前冷库温度大于或等于第二设定温度的情况下发送的电磁阀吸合指令后，启动模块470可控制压缩机启动运行。这样，在冷凝机组中压缩机处于运行状态时，若(Ps0-ΔPs)≤Ps≤(Ps0+ΔPs)不成立时，第二控制模块480则仍然可根据当前蒸发压力值以及当前目标蒸发压力值，控制压缩机的运行。Of course, after receiving the solenoid valve closing command sent by the air cooler when it is determined that the current cold storage temperature is greater than or equal to the second set temperature, the starting module 470 can control the compressor to start running. In this way, when the compressor in the condensing unit is in operation, if (Ps0-ΔPs) ≤ Ps ≤ (Ps0 + ΔPs) does not hold, the second control module 480 can still determine based on the current evaporation pressure value and the current target evaporation pressure value. Control the operation of the compressor.
可见，本实施例中，用于冷库冷凝机组控制的装置根据当前蒸发压力值、目标蒸发压力值以及当前冷库温度，来控制冷凝机组中压缩机的运行，这样，会加快冷库温度达到要求的速度，减少冷库温度达不到目标库温或降温时间过长，而导致仓储货物品质恶化问题出现的几率，提高了冷库库温的稳定性。并且，在冷凝机组运行过程中，还可自动修正和更新目标蒸发压力值，减少了冷库从业人员对冷库运行的影响，进一步提高了冷库控制的智能性。It can be seen that in this embodiment, the device used to control the cold storage condensing unit controls the operation of the compressor in the condensing unit according to the current evaporation pressure value, the target evaporation pressure value and the current cold storage temperature. In this way, the cold storage temperature will be accelerated to reach the required speed. , reduce the probability that the cold storage temperature fails to reach the target temperature or the cooling time is too long, resulting in the deterioration of the quality of the stored goods, and improves the stability of the cold storage temperature. In addition, during the operation of the condensing unit, the target evaporation pressure value can be automatically corrected and updated, which reduces the impact of cold storage employees on the operation of the cold storage and further improves the intelligence of cold storage control.
