Handling method of refrigeration and air conditioning cycle equipment, refrigerant recovery mechanism of refrigeration and air conditioning cycle equipment

摘要

PROBLEM TO BE SOLVED: To surely recover even a minute amount of refrigerant in moving to surely prevent the unsafety caused by leakage of the refrigerant in a refrigeration air conditioner using the combustible refrigerant, and the harmful refrigerant of even a minute amount.;SOLUTION: A refrigerant recovering container is connected to a discharge port of a vacuum pump to recover the refrigerant discharged from the discharge port, when the refrigerant used in the refrigeration air conditioning cycle is recovered in an outdoor machine by pumping-down operation, and then the refrigerant remaining in an indoor machine and a connection pipe is recovered by using the vacuum pump. Whereby this handling method of the refrigeration cycling device of high safety, effective even for the protection of the global environment can be achieved.;COPYRIGHT: (C)2004,JPO
