after the compressor 1 is started, the vapor of the sucked refrigerant is compressed into high-temperature and high-pressure gas, the gas enters the air-cooled condenser 3 after flowing through the first regulating valve 21 to be condensed and released heat to form medium-temperature and high-pressure liquid refrigerant with a certain supercooling degree, the liquid refrigerant is finally collected in the liquid accumulator 4, the medium-temperature and high-pressure liquid refrigerant enters the expansion valve 7 after flowing through the filter 6, the refrigerant is changed into low-temperature and low-pressure gas-liquid mixture through the throttling and pressure reduction action of the expansion valve 7 to enter the first inlet 8a of the evaporator 8, the liquid refrigerant is violently vaporized in the evaporator 8 to absorb heat, so that the temperature of the cooling liquid passing through the other side of the evaporator 8 is reduced, the refrigerant is in a gas state after absorbing heat and then flows out of the first outlet 8b of the evaporator 8, and returns to the compressor 1 to complete the refrigerant circulation after entering the gas-liquid separator 9. On the other hand, after passing through the first ball valve 121, the coolant in the reservoir tank 11 is delivered to the heat load 15 by the circulation pump 14, and the coolant absorbs heat from the heat load 15, increases in temperature, enters the second inlet 8c of the evaporator 8, exchanges heat with the refrigerant in the evaporator 8, decreases in temperature, flows out from the second outlet 8d of the evaporator 8, and then flows back to the reservoir tank 11, completing the coolant circulation.
When the heat load in the heat load 15 is reduced, the controller controls the opening degree of the first regulating valve 21 and the second regulating valve 22 through the temperature value feedback of the temperature sensor 131 and the temperature sensor 132, a part of high-temperature and high-pressure gas discharged from the compressor 1 flows into the first regulating valve 21 to complete the working process according to the refrigerant cycle, the other part of high-temperature and high-pressure gas flows into the second regulating valve 22 to enter the heat exchange coil 10 to exchange heat with the cooling liquid in the liquid storage tank 11, flows through the check valve 5 after the temperature is reduced, then is merged with the liquid refrigerant flowing out from the air-cooled condenser 3, then enters the liquid storage tank 4, and then completes the working process according to the refrigerant cycle. According to the change proportion of the heat load in the heat load 15, the controller adjusts the opening degree of the first adjusting valve 21 and the second adjusting valve 22, so as to adjust the flow of the refrigerant entering the heat exchange coil 10, adjust the heat exchange amount of the refrigerant and the cooling liquid, and realize the accurate control of the liquid supply temperature of the heat load.
