CONSTITUTION:When a high pressure side solenoid valve 14 and a recovery gas cylinder side solenoid vale 16 are opened and a low pressure side solenoid valve 15 is clod, the high pressure side of a refrigerant circuit 21 is connected to a recovery gas cylinder 10, and high pressure liquid refrigerant cooled and condend by a compressor 6 and a condenr 7 of the circuit 21 is fed into the low pressure cylinder 10. In this ca, the liquid refrigerant is pasd through an oil parator 20, and impurities in the refrigerant such as oil, etc., of the compressor 6 flowing out together with the refrigerant are removed. When the recovery of the refrigerant is started, a recovery timer 17 is simultaneously operated, and the solenoid valve 16 is clod after about two minutes. Then, a differential pressure nsing timer 18 is operated, and the valve 16 is relead after 15 conds. Thus, if a small space is provided around a facility, the refrigerant can be recovered, and the recovering time can be greatly shortened.社会保险基金管理
