The controller 1 is connected to the compressor 2 and the condenser 3, respectively, for controlling the operating frequency of the compressor 2 and/or controlling the power of the two-speed fan condenser, so that energy consumption can be saved and the power consumption can be reduced while meeting the heat dissipation requirement. pollutant emission.
值得说明的是，上述第一类部件4是指在工作过程中易发热，需要降温至合适温度以提高部件性能的一类部件，可以包括电机41、电子电力单元42、充电机43以及发动机中的至少一种。为了能够精确控制第一类部件4的温度，每一第一类部件4上可以设置有温度传感器，用于实时检测每一第一类部件4的温度，控制器1则根据温度传感器实时检测到的第一类部件4的温度，调节冷凝管道6流向第一类部件4的蒸发器5的冷媒流量，以调节第一类部件(4)的温度。示例地，蒸发器5设置有冷媒入口61以及冷媒出口62，冷凝管道6通过膨胀阀与蒸发器5相连，控制器1通过调节膨胀阀的开度值，以调节冷凝管道6流向蒸发器5的冷媒流量。其中，冷媒是空调冷冻***中用以传递热能，易发生吸热/放热反应从而产生冷冻效果的工作流体，例如物质R1234yf和R1234ze都是新一代环保冷媒。It should be noted that the first type of component 4 refers to a type of component that is prone to heat during operation and needs to be cooled to a suitable temperature to improve the performance of the component, and may include a motor 41, an electronic power unit 42, a charger 43, and an engine. At least one of them. In order to be able to accurately control the temperature of the first type of component 4, each of the first component 4 may be provided with a temperature sensor for detecting the temperature of each of the first component 4 in real time, and the controller 1 detects the real time according to the temperature sensor. The temperature of the first type of component 4 regulates the flow of refrigerant to the evaporator 5 of the first type of component 4 of the condensing conduit 6 to regulate the temperature of the first type of component (4). For example, the evaporator 5 is provided with a refrigerant inlet 61 and a refrigerant outlet 62, and the condensing duct 6 is connected to the evaporator 5 through an expansion valve, and the controller 1 adjusts the opening value of the expansion valve to adjust the flow of the condensing duct 6 to the evaporator 5. Refrigerant flow. Among them, the refrigerant is a working fluid used in the air conditioning refrigeration system to transfer heat energy and is prone to heat absorption/exothermic reaction to produce a freezing effect. For example, the substances R1234yf and R1234ze are new-generation environmentally friendly refrigerants.
在一种可能的实施方式中，控制器1可以是整车控制器，每一第一类部件4的标准温度阈值可以根据实际情况进行实车标定，在设置于第一类部件4上的温度传感器检测到的该部件的温度大于标准温度阈值时，控制器1控制压缩机2将低温低压的气态冷媒压缩为高温高压的气态冷媒，该高温高压气态冷媒流经冷凝器3后可以转变为高温高压液态冷媒，所生成的高温高压液态冷媒通过膨胀阀的节流孔后成为低温低压的雾状的液态冷媒，在进入蒸发器5后，随即蒸发为低温低压的气态冷媒。由于液态冷媒气化过程是吸热过程，能够带走周围空气的热量，从而可以对第一类部件4的工作环境起到制冷作用。In a possible implementation manner, the controller 1 may be a vehicle controller, and the standard temperature threshold of each of the first type components 4 may be calibrated according to actual conditions, and the temperature set on the first type component 4 When the temperature of the component detected by the sensor is greater than the standard temperature threshold, the controller 1 controls the compressor 2 to compress the low-temperature low-pressure gaseous refrigerant into a high-temperature high-pressure gaseous refrigerant, and the high-temperature high-pressure gaseous refrigerant can be converted into a high temperature after flowing through the condenser 3. The high-pressure liquid refrigerant generates high-temperature and high-pressure liquid refrigerant through the orifice of the expansion valve and becomes a low-temperature low-pressure mist-like liquid refrigerant. After entering the evaporator 5, it is evaporated into a low-temperature low-pressure gaseous refrigerant. Since the liquid refrigerant gasification process is an endothermic process, the heat of the surrounding air can be taken away, so that the working environment of the first type of component 4 can be cooled.

When the temperature detected by the temperature sensor for detecting the temperature of the cab air conditioner 81 connected to the controller 1 is less than the set temperature, the controller 1 controls the selection switch to turn on the electronic fan and the heater 71, and the electronic fan 72 operates. The air in the cab air conditioner 81 circulates, and the air is heated by the heater 71 to heat the vehicle cab.
当与控制器1相连的用于检测驾驶室空调81的温度的温度传感器检测到的温度大于预定的温度时，控制器1控制选择开关导通电子风扇和蒸发器5，并根据检测到的温度调节冷凝管道6流向温控装置7中的蒸发器5的冷媒流量，以对车辆驾驶室进行温度的调节，从而起到降温的效果。When the temperature detected by the temperature sensor for detecting the temperature of the cab air conditioner 81 connected to the controller 1 is greater than a predetermined temperature, the controller 1 controls the selection switch to turn on the electronic fan and the evaporator 5, and according to the detected temperature The flow rate of the refrigerant flowing through the condensing duct 6 to the evaporator 5 in the temperature control device 7 is adjusted to adjust the temperature of the vehicle cab, thereby exerting a cooling effect.
示例地，图7是本公开提供的一种设置有温控装置的电池箱体的结构示意图，如图7所示，第二类部件8还可以是电池箱体82。为提高车辆电池的能量转换效率以及使用寿命，该电池箱体82的内的环境温度需要控制在标准温度阈值的一定范围内。例如，标准温度阈值可以是23℃，环境温度需要控制在18℃～28℃的范围内。当与控制器1相连的用于检测电池箱体82的温 度的温度传感器检测到的温度小于环境温度范围的下限时，控制器1控制选择开关导通电子风扇和加热器71，电子风扇72运转可以使电池箱体82内的空气循环流动，空气经过加热器71加热后，与电池箱体82内的电池发生热交换，从而对车辆电池起到加热的效果。由于电池在使用过程中自身会产生热量，同时电池箱体82密闭，因此利用温控装置7在气温较低时对车辆电池加热的过程高效且节能。For example, FIG. 7 is a schematic structural diagram of a battery case provided with a temperature control device provided by the present disclosure. As shown in FIG. 7 , the second type component 8 may also be a battery case 82 . In order to improve the energy conversion efficiency and service life of the vehicle battery, the ambient temperature inside the battery case 82 needs to be controlled within a certain range of the standard temperature threshold. For example, the standard temperature threshold can be 23 ° C and the ambient temperature needs to be controlled in the range of 18 ° C to 28 ° C. When the temperature detected by the temperature sensor connected to the controller 1 for detecting the temperature of the battery case 82 is lower than the lower limit of the ambient temperature range, the controller 1 controls the selection switch to turn on the electronic fan and the heater 71, and the electronic fan 72 operates. The air in the battery case 82 can be circulated, and the air is heated by the heater 71 to exchange heat with the battery in the battery case 82, thereby heating the vehicle battery. Since the battery itself generates heat during use and the battery case 82 is sealed, the process of heating the vehicle battery when the temperature is low is utilized by the temperature control device 7 to be efficient and energy-saving.
当与控制器1相连的用于检测电池箱体82的温度的温度传感器检测到的温度大于环境温度范围的上限时，控制器1控制选择开关导通电子风扇和蒸发器5，并根据检测到的温度调节冷凝管道6流向温控装置7中的蒸发器5的冷媒流量，以对电池箱体82进行温度的调节，从而起到加热的效果。When the temperature detected by the temperature sensor connected to the controller 1 for detecting the temperature of the battery case 82 is greater than the upper limit of the ambient temperature range, the controller 1 controls the selection switch to turn on the electronic fan and the evaporator 5, and according to the detection The temperature-regulating condensing duct 6 flows to the refrigerant flow rate of the evaporator 5 in the temperature control device 7 to adjust the temperature of the battery case 82, thereby exerting a heating effect.
采用上述车载温控***，可以对第二类部件8的工作环境的温度进行控制，确保第二类部件8工作在合适的温度范围内，以提升第二类部件8工作性能以及寿命。其中，对于受温度影响较大的车辆电池而言，稳定的温度控制可以实现电池能量的高效转换，并为车辆电池***升级为石墨烯电池提供保障。With the above-mentioned vehicle temperature control system, the temperature of the working environment of the second type of component 8 can be controlled to ensure that the second type of component 8 operates within a suitable temperature range to improve the working performance and life of the second component 8. Among them, for vehicle batteries that are greatly affected by temperature, stable temperature control can achieve efficient conversion of battery energy and provide guarantee for upgrading vehicle battery system to graphene battery.
