The working principle is explained as follows: the compressor refrigeration system is connected with the electric heating system through the evaporator 9, when the refrigeration state is achieved, the compressor 1 starts to compress a refrigerant to discharge high-temperature and high-pressure gas, the high-pressure and high-pressure liquid is discharged after the refrigerant exchanges heat with cooling water through the high-low pressure controller to the condenser 3, the refrigerant passes through the liquid storage tank 5 and the drying filter 6 and then reaches the electromagnetic valve 7 and the thermostatic expansion valve 8, the refrigerant is throttled and depressurized through the thermostatic expansion valve 8, and the refrigerant is converted into medium-pressure gas from the high-pressure and high-temperature liquid and enters the evaporator 9 to exchange heat with a heat exchange medium, and then is converted into low-temperature gas and liquid to return to the return port of the compressor 1. When the equipment 27 is started, the circulating system also operates, the circulating pump 13 pumps a circulating medium into the evaporator 9 to exchange heat with the refrigerant, the circulating medium after heat exchange passes through the circulating pump 13 to the used equipment 27, the temperature sensor at the outlet of the equipment 27 detects whether the temperature of the outlet of the equipment reaches the set temperature, and the outlet pressure sensor detects whether the pressure of the outlet of the equipment is within the pressure-bearing range of the equipment.
When the heating state is achieved, the circulating pump 13 is started, the heater 18 is started, and circulating media enter the inlet of the circulating pump 13 through a pipeline, are pumped into the heater 18 through the circulating pump 13 and finally reach the outlet of the equipment 27.

When the device 27 is used for high-temperature testing, the circulating pump 13 is started, the heater 18 is started, when the device 27 is higher than the use temperature, the compressor 1 is started, high-pressure normal-temperature liquid is discharged after heat exchange with cooling water from the condenser 3 through the high-low pressure controller, the refrigerant passes through the liquid storage tank 5 and the drying filter 6 and then reaches the electromagnetic valve 7 and the thermostatic expansion valve 8, the refrigerant is subjected to throttling and pressure reduction through the thermostatic expansion valve 8, the refrigerant is converted into medium-pressure gas from the high-pressure normal-temperature liquid and enters the evaporator 9 to exchange heat with a heat exchange medium, the outlet temperature of the circulating pump of the device is balanced, and the use temperature is reached.
