ABSTRACT:
A high capacity refrigerant apparatus is made up of a heat exchanger which receives refrigerant from the system to be drained in heat exchange relation to a coolant from a vapor compressor circuit, and a liquid pump discharges the refrigerant from the heat exchanger so long as the liquid refrigerant in the heat exchanger remains at a particular level; otherwise, the refrigerant is drawn through a second vapor compressor circuit and completely condensed prior to discharge. In a modified form, a lower capacity refrigerant reclamation apparatus, a reciculating coolant tube vaporizes a limited amount of refrigerant and returns it back through the heat exchanger so as not to require a separate vapor compressor system for the heat exchange cooling medium.
