Abstract
A portable refrigerant recycle unit is disposed adjacent to a recycle (reclamation) unit for receiving excess or waste heat discharged therefrom. Liquid and gas refrigerant (e.g., freon) flow from the unit being evacuated to a heat exchanger. A fan draws discharged heat from the reclamation unit across the fins of the heat exchanger. Liquid freon flowing through the heat exchanger is vaporized as it is heated by the air drawn by the fan containing the heat discharged from unit. Gaseous freon flows from the heat exchanger to an oil seperator. Freon vapor then flows from the oil seperator through a filter to the recycle unit output. The reclamation unit condenses the recycle unit output of vapor freon to a liquid. The liquid freon flows from the output of the reclamation to a refrigerant receiver.
