ABSTRACT:
A process and apparatus for evacuating refrigerant for recovery from a conventional refrigeration sytems, e.g. automobile air conditions, preferably by attachment to a manifold having multiple evacuation devices, e.g. compressor, vacuum pump, transfer pump with the evacuation devices discharging through self-closing quick connect valves into at least one flexible accumulator, e.g. a bag mounted onto a manifold, and with an additional transfer pump evacuating the bag gradually to a recovery system which can be a conventional refrigerant recovery condensing unit with purification. Facilities for receiving bags filled from refrigeration systems which are remote from the system, e.g. home refrigerators, can be provided to weigh the contents into the manifold for recovery.
