Connecting the refrigeration compressor to be tested with the refrigeration system 2, opening the high-pressure pipe gate 71 and the low-pressure pipe gate 81, and only enabling the refrigeration compressor and the refrigeration system 2 to form refrigerant circulating refrigeration loop communication.

The electronic control device 11 controls the booster pump 52 to start working, and opens the filling valve 91, and the liquid refrigerant in the storage tank 10 is injected into the refrigerant circulation refrigeration circuit through the filling line 50. Wherein the mass flow meter 53 detects the refrigerant passing through the charging line 50, and when the mass of the charged refrigerant reaches a preset value, the charging valve 91 is closed and the booster pump 52 stops operating.
At this time, the refrigeration compressor to be tested, the condensing fan 25 and the evaporating fan 26 are started, and the refrigerant flows in the refrigerant circulation refrigeration loop, that is, the refrigeration system 2 starts the refrigeration operation, and in this process, the performance of the refrigeration compressor 14 is detected. Since the refrigerant charging system 5 charges the liquid refrigerant between the condenser 21 and the refrigerant filter 22, when the refrigeration system 2 is in operation, the liquid refrigerant directly enters the expansion valve 23 and the evaporator 24 through the refrigerant filter 22 and starts to refrigerate, thereby shortening the performance testing time of the refrigeration compressor. After the detection of the refrigerant compressor is completed, the operation of the refrigerant compressor, the condensing fan 25 and the evaporating fan 26 is stopped.
The electric control device 11 controls the recovery compressor 63 to start and opens the output valve 93 and the bypass valve 29. Meanwhile, the high pressure input valve 73 and the low pressure input valve 83 are opened for a predetermined period of time, and the gaseous refrigerant in the storage tank 10 is injected into the refrigerant cycle refrigerating circuit through the high pressure input valve 73 and the low pressure input valve 83. One path of the gaseous refrigerant enters the condenser 21 through the high-pressure pipe brake 71, the other path of the gaseous refrigerant enters the evaporator 24 through the low-pressure pipe brake 81, so that the liquid refrigerant at the bottom in the condenser 21 and the evaporator 24 is flushed out, and the liquid refrigerant in the evaporator 24 is converged into the output valve 93 through the bypass valve 29, the refrigeration filter 22 and the liquid refrigerant in the condenser 21. The bypass valve 29 shortens the time for the liquid refrigerant to pass through the expansion valve 23, i.e., shortens the refrigerant recovery time. Wherein the preset period of time is the time required for the liquid refrigerant to flow out of the refrigerant circulation refrigeration loop.
After the preset period of time, the high pressure input valve 73 and the low pressure input valve 83 are closed, and the electric control device 11 controls the high pressure recovery valve 74 and the low pressure recovery valve 84 to be opened. The recovery compressor 63 continues to operate, and under the suction action of the recovery compressor 63, the gaseous refrigerant in the refrigerant circulation refrigeration circuit is collected into the recovery filter 61 through the output valve 93, the high-pressure recovery valve 74 and the low-pressure recovery valve 84, and the solid impurities in the refrigerant are filtered by the recovery filter 61.

The frozen lubricating oil remains in the refrigerant oil separator 601, the purified gas refrigerant enters the recovery compressor 63, the recovery compressor 63 pressurizes the purified gas refrigerant and enters the radiator 65 through the second check valve 64 to be depressurized and liquefied, and finally the purified refrigerant enters the storage tank 10. Preferably, the radiator 65 is also another condenser 21, and the purified gas refrigerant is liquefied into the liquid refrigerant to be introduced into the storage tank 10. When the high pressure transmitter 41 and the low pressure transmitter 42 detect that the pressure drop of the refrigerant circulation refrigeration loop reaches a preset value, the recovery compressor 63 and the radiator 65 stop working, the output valve 93, the high pressure recovery valve 74, the low pressure recovery valve 84, the high pressure pipe gate 71 and the low pressure pipe gate 81 are closed, the detected refrigeration compressor can be taken down, and the testing process of the next refrigeration compressor 14 to be tested is performed.
During operation, the refrigerant in the storage tank 10 is recovered, purified and reused. Of course, the inlet system replenishes the storage tank 10 with lost refrigerant. In addition, because the high-pressure pipe gate 71 and the low-pressure pipe gate 81 are closed, the refrigerant circulation refrigeration circuit in the casing 1 is disconnected from the outside air, and therefore, when the next test procedure of the refrigeration compressor 14 to be tested is performed, only the air in the refrigeration compressor to be tested, the high-pressure connecting pipe 12 and the low-pressure connecting pipe 13 needs to be vacuumized, and the vacuum time of the vacuum pump 40 is shortened.
After the refrigerant is recovered, the electronic control device 11 controls the air return valve 604 to open, and the gaseous refrigerant at the high-pressure end of the recovery compressor 63 flows back into the refrigerant oil separator 601 through the air return valve 604. The electric control device 11 controls the oil drain valve 602 to open, and the frozen lubricating oil in the refrigerant oil separator 601 flows out from the oil drain valve 602 at the bottom to the oil receiving bottle 603 under the pressure of the gaseous refrigerant.
The recovery compressor 63 is operated, and the gaseous refrigerant in the storage tank 10 enters the refrigerant circulation refrigeration circuit in the casing 1 through the high pressure input valve 73 and the low pressure input valve 83, respectively, so that the liquid refrigerant in the refrigerant circulation refrigeration circuit is recovered into the storage tank 10 through the high pressure recovery valve 74, the low pressure recovery valve 84, and the output valve 93.
