ABSTRACT:
A portable, electrically powered refrigerant recovery system and method uses a single manifold to reduce fabrication time and costs. A hot gas discharge port in combination with a check valve allows the recovery system to be utilized as a vacuum pump as well as a refrigerant recovery device. A rectangular aluminum oil separator has internal baffles and is located between the inlet and a compressor. A low-voltage control circuit uses a latching circuit to avoid short cycling of the compressor and thereby increase compressor life. The system provides an improved push-pull recovery method in which superheated refrigerant vapor from the compressor is diverted directly to the system being recovered so that the superheated vapor is returned to the unit being emptied to speed the recovery process.
