When the equipment is started, the circulating pump 21 in the electric heating energy storage system also runs along with the equipment, the circulating pump 21 pumps circulating medium into the evaporator 13 to exchange heat with the refrigerant, the circulating medium after heat exchange is pumped out to an equipment outlet through the circulating pump 21, whether the equipment outlet temperature reaches a set temperature is detected by the outlet temperature sensor 31, whether the equipment outlet pressure is in an equipment pressure-bearing range is detected by the outlet pressure sensor, and meanwhile whether the display flow of the outlet flow sensor meets the customer requirement is checked.
When the heating state is adopted, the circulating pump 21 is started, the heater 25 is started, circulating medium is pumped into the pipeline through the circulating pump 21 and enters the inlet of the test equipment, and is pumped into the energy storage tank 22 through the circulating pump 21, and the medium is heated in the energy storage tank 22 by being contacted with the electric heater 25. Whether the temperature of the outlet of the equipment reaches the set temperature is detected by the temperature sensor of the outlet, whether the pressure of the outlet of the equipment is in the pressure-bearing range of the equipment is detected by the pressure sensor of the outlet, and whether the display flow of the outlet flow sensor meets the requirements of customers is checked.

As shown in fig. 1, two temperature points of high temperature and low temperature can be tested simultaneously, when the test requirement is low temperature test, the compressor 1 is started, the circulating pump 21 is started until the equipment outlet temperature sensor reaches the set temperature point, and the circulating system with the equipment energy storage tank can collect the energy rich in the test equipment to the energy storage tank, so that the energy output of the compressor is reduced, the cooling time is shortened, and meanwhile, the power consumption is reduced. When the test equipment is arranged for high-temperature test, the circulating pump 21 is started, the heater 25 is started until the outlet temperature is detected to reach the customer set temperature, when the outlet temperature 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 7 through the high-low pressure controller, the refrigerant passes through the energy storage tank 8 and the drying filter 9 and then enters the electromagnetic expansion valve 11, the refrigerant is subjected to throttling and depressurization through the electromagnetic expansion valve 11, the refrigerant is converted into medium-pressure gas from the high-pressure normal-temperature liquid and enters the primary precooler for cooling and enters the secondary evaporator 13 for heat exchange with a heat exchange medium, the circulating pump outlet temperature of the equipment is balanced, and the use temperature is reached.
