[0018] The working principle and use process of the utility model are as follows:

[0019] Refrigeration working principle: controller 14 provides start signal, and the compressor 1 is started to run, and the low-temperature and low-pressure gas is compressed into high-temperature and high-pressure gas and is discharged from the exhaust port of the compressor 1; the high-temperature and high-pressure gas enters the oil separator 3 through copper pipe one 2; the oil separator 3 separates the oil in the refrigerant gas and enters the condenser 6 through copper pipe two 4; the condenser 6 cools the high-temperature and high-pressure gas into high-temperature and high-pressure liquid by heat dissipation, and the high-temperature and high-pressure liquid is stored and pressure stabilized in the liquid reservoir 7; after pressure stabilization, the high-temperature and high-pressure liquid enters the drying filter 8 through copper pipe four 17, absorbs moisture in the refrigerant and removes impurities in the refrigerant. After the drying and cleaning of the refrigerant liquid, the high-temperature and high-pressure liquid enters the liquid mirror 11 through copper pipe five 18 to check whether the refrigerant injection amount needs to be increased, and then the clean refrigerant liquid enters the evaporator through the liquid supply valve 12 through copper pipe six 19 to be gasified and evaporated, and is evaporated into low-temperature and low-pressure gas; the low-temperature and low-pressure gas enters the unit through the back gas valve 13, and the low-temperature and low-pressure gas-liquid mixed refrigerant is separated into gas and liquid in the gas-liquid separator 10, and the low-temperature and low-pressure gas is compressed through the suction port of the compressor 1 to become high-temperature and high-pressure gas and circulate again.

[0020] Liquid injection protection working principle: when the exhaust temperature sensor on the controller 14 detects that the exhaust temperature exceeds a certain value, the liquid injection expansion valve 9 starts to work, and the expansion valve is continuously opened according to the rising trend of the exhaust temperature, and the cooling capacity is continuously increased, so that the exhaust temperature is always controlled in a safe operation interval of the compressor 1. When the exhaust temperature decreases, the expansion valve is continuously closed. Until the expansion valve is completely closed.

[0021] The working principle of the exhaust air is as follows: the controller 14 provides a starting signal, the condensing fan 5 is started to work, the low-temperature air from the outside is exchanged with the high-temperature and high-pressure refrigerant through the condenser 6. The positive pressure flow guide is formed by the shell 15, and the air is discharged from the front of the machine. The condensing fan 5 continuously works, and the heat generated by the refrigerant is continuously discharged.
