Referring to fig. 1, the present invention provides an energy storage distributed temperature control method for an environmental test chamber, which includes a refrigeration and heating system 100, a heat conductive agent system 200, a control system 300 and a plurality of test chamber bodies 400; the refrigerating and heating system 100 and the heat conducting agent system 200 form a loop, the heat conducting agent system 200 is communicated with a plurality of test boxes 400, and the connection relationship between the test boxes 400 and the control system 300 is parallel;
after the temperature of the heat-conducting agent system 200 reaches the first temperature, the control system 300 controls the heat-conducting agent system 200 to output the same and/or different flow of fluid to each test box 400 according to different temperature requirements of the test boxes 400, and the different test boxes 400 obtain the same or different second temperatures, and after the heat-conducting agent system 200 exchanges heat with the test boxes 400, the temperature of the heat-conducting agent system 200 changes, and when the temperature of the heat-conducting agent system 200 is different from the first temperature, the refrigeration and heating system 100 enables the heat-conducting agent system (200) to reach the first temperature again, namely, the heat-conducting agent system (200) keeps constant temperature, the required power is lower, and the power of the whole unit is smaller.
In this embodiment, the refrigeration and heating system 100 includes a refrigeration compressor 101, a condenser 105, a throttling device 102, an evaporator 103, a heater 104, and related auxiliary accessories not shown. The refrigeration compressor 101, the condenser 105, the throttling device 102 and the evaporator 103 are sequentially connected by copper pipes to form a circulation system, the refrigeration system is filled with refrigerant, and the refrigerant circularly flows in the circulation system. The low-temperature low-pressure gaseous refrigerant is changed into high-temperature high-pressure gaseous refrigerant after working by the refrigeration compressor 101, is changed into a normal-temperature high-pressure liquid state after heat release by the condenser 105, is changed into a low-temperature low-pressure gas-liquid mixture by the throttling function of the throttling device 102, and is then absorbed by the evaporator 103 to be changed into a low-temperature low-pressure gaseous state, and finally returns to the refrigeration compressor 101 to be compressed, thereby completing a cycle.
Preferably, the thermal conductor system 200 comprises a thermal conductor tank 201, a plurality of flow pumps 204, a plurality of heat exchangers 202, a circulation line 203, and a thermal conductor flowing within the system. The heat conducting agent energy storage tank 201, the flow pump 204 and the heat exchanger 202 are sequentially connected through pipelines to form a plurality of circulating pipelines 203, and the heat conducting agent energy storage tank 201 and the pipelines are filled with a proper heat conducting agent. The evaporator 103 and the heater 104 of the refrigeration and heating system 100 are installed in the heat transfer agent storage tank 201, and exchange heat with the heat transfer agent, respectively, to lower or raise the temperature of the heat transfer agent. Each test chamber 400 is provided with a heat exchanger 202 and a set of circulation pipes 203 which are arranged inside, each set of circulation pipes 203 is provided with a flow pump 204, and the flow rate of the heat conducting agent in the circulation pipes 203 is controlled by controlling the operating frequency of the flow pump 204, so that the refrigerating capacity or the heating capacity of the test chamber 400 is further controlled.
It is noted that the control system 300 includes a controller 301, an internal tank temperature sensor 302, and a flow pump 204. The temperature of the inner box of the test box 400 detected by the inner box temperature sensor 302 is compared with the set value of the temperature of the inner box, and the controller 301 controls the cooling capacity or heating capacity of the flow control heat exchanger 202 of the flow pump 204 by PID adjustment. When the cooling load or the heating load of the test chamber 400 is large, the controller 301 increases the flow rate of the heat conductive agent in the circulation line 203 by increasing the operating frequency of the flow pump 204, thereby further controlling the cooling capacity or the heating capacity of the test chamber 400.

The specific control method is as follows:
when refrigeration is needed: the heat conducting agent energy storage box 201 is filled with a proper amount of heat conducting agent, before the test box 400 is used, the refrigerating and heating system 100 reduces the temperature of the heat conducting agent in the heat conducting agent energy storage box 201 to a certain temperature in advance to achieve the purpose of cold storage, the temperature is defined as cold storage temperature, the cold storage temperature is lower than the lowest test temperature of all the test boxes 400, and the refrigerating and heating system 100 stops running after the temperature of the heat conducting agent is reduced to the cold storage temperature. As the cooling amount of the heat transfer agent is consumed, the temperature of the heat transfer agent in the heat transfer agent storage tank 201 is gradually increased, and when the temperature is increased to a certain temperature, the cooling and heating system 100 is turned on again, so that the temperature of the heat transfer agent is reduced to the cooling storage temperature again. When each test box 400 needs to be refrigerated, the respective control system 300 regulates and controls the flow of the heat conducting agent of each circulation pipeline 203 according to the respective cooling load in a PID regulation mode so as to meet the refrigeration requirement of each test box 400.
When heating is needed: before the test box 400 is used, the refrigerating and heating system 100 heats the heat conducting agent in the heat conducting agent energy storage box 201 to a certain temperature in advance to achieve the heat storage purpose, wherein the temperature is defined as a heat storage temperature, the heat storage temperature is higher than the highest test temperature of all the test box 400, and the refrigerating and heating system 100 stops running after the temperature of the heat conducting agent rises to the heat storage temperature. As the heat of the heat-conducting agent is consumed, the temperature of the heat-conducting agent in the heat-conducting agent energy storage tank 201 gradually decreases, and when the temperature decreases to a certain temperature, the refrigeration and heating system 100 is turned on again, so that the temperature of the heat-conducting agent increases again to the heat storage temperature. When each test box 400 needs to be heated, the respective control system 300 regulates and controls the flow of the heat conducting agent of each circulation pipeline 203 according to the respective heat load in a PID regulation mode so as to meet the heating requirement of each test box 400.

The evaporator 103 and the heater 104 of the refrigeration and heating system 100 are installed in the heat transfer agent storage tank 201 to exchange heat with the heat transfer agent, so that the temperature of the heat transfer agent is lowered or raised. Each test chamber 400 is provided with a heat exchanger 202 and a set of circulation pipelines 203 which are arranged in the test chamber, each set of circulation pipelines 203 is provided with a three-way proportional valve 206, and the opening degree of the three-way proportional valve 206 is controlled to control the flow rate of the heat conducting agent in the circulation pipelines 203 and further control the refrigerating capacity or the heating capacity of the test chamber 400.

The low-temperature low-pressure gaseous refrigerant is changed into a high-temperature high-pressure gaseous refrigerant through the work of the refrigeration compressor 101, the high-temperature high-pressure gaseous refrigerant enters the precooler 106 to release a certain amount of heat and reduce the temperature, then flows through the condenser 105 to release heat and then is changed into a normal-temperature high-pressure liquid state, the refrigerant at the outlet of the throttling device 102 is changed into a low-temperature low-pressure gas-liquid mixture through the throttling effect of the throttling device 102, the refrigerant enters the evaporator 103 again to absorb heat and is changed into a low-temperature low-pressure gaseous state, and finally returns to the refrigeration compressor 101 to be compressed, so that one cycle is completed.

The evaporator 103 and the heater 104 of the refrigeration and heating system 100 are installed in the first group of heat-conductive agent storage tanks 201 to exchange heat with the heat-conductive agent, respectively, so that the temperature of the heat-conductive agent is lowered or raised. Precooler 106 is mounted within a second set of heat-transfer agent storage tanks 201 and emits heat to raise the temperature of the heat-transfer agent. Each test chamber 400 is provided with a heat exchanger 202 and a set of circulation pipes 203 which are arranged inside, each set of circulation pipes 203 is provided with a flow pump 204, and the flow rate of the heat conducting agent in the circulation pipes 203 is controlled by controlling the operating frequency of the flow pump 204, so that the refrigerating capacity or the heating capacity of the test chamber 400 is further controlled.
It should be noted that the specific control manner is as follows:
the heat transfer agent in the first group of heat transfer agent storage tanks 201 can be cooled or heated, so that the test tank 400 forming a loop with the first group of heat transfer agent storage tanks 201 can be subjected to a low temperature test or a high temperature test.
When refrigeration is needed: the first group of heat-conducting agent energy storage boxes 201 are filled with a proper amount of heat-conducting agent, before the test box 400 is used, the refrigerating and heating system 100 reduces the temperature of the heat-conducting agent in the first group of heat-conducting agent energy storage boxes 201 to a certain temperature in advance to achieve the purpose of cold storage, the temperature is defined as cold storage temperature, the cold storage temperature is lower than the lowest test temperature of all the test box 400, and after the temperature of the heat-conducting agent is reduced to the cold storage temperature, the refrigerating and heating system 100 stops running. As the cooling capacity of the heat transfer agent is consumed, the temperature of the heat transfer agent in the first group of heat transfer agent storage tanks 201 is gradually increased, and when the temperature is increased to a certain temperature, the refrigeration and heating system 100 is turned on again, so that the temperature of the heat transfer agent is reduced to the cooling storage temperature again. When each test box 400 needs to be refrigerated, the respective control system 300 regulates and controls the flow of the heat conducting agent of each circulation pipeline 203 according to the respective cooling load in a PID regulation mode so as to meet the refrigeration requirement of each test box 400.
