Abstract
A refrigerant recovery apparatus has a combination heat exchanger which both serves as a condenser and evaporator. The heat exchanger has spaced apart headers, each header having a plurality of holes. Finned evaporator tubes and finned condenser tubes extend between the headers. The tubes are parallel to each other and perpendicular to the header. A fan blows air through the evaporator. Refrigerant fluid flows through the condenser and evaporator sections of the heat exchanger. The water condensate formed in the evaporator section will evaporate as a result of the heat from the condenser section. In one embodiment, the evaporator tubes are sandwiched between condenser tubes on the forward and rearward sides of the heat exchanger. In another embodiment, the evaporator tubes are located above the condenser tubes.
