ABSTRACT:
A refrigerant handling system that includes a compressor and an evaporator for adding heat to refrigerant fed to the compressor inlet. A first condenser is connected to the compressor outlet and disposed in heat exchange relationship to the evaporator for at least partially condensing refrigerant vapor from the compressor outlet by transfer of heat to refrigerant in the evaporator. A second condenser is not in heat exchange relationship with the evaporator. The first and second condensers are connected in series with the compressor outlet, and one or more valves are connected to the second condenser for selectively bypassing refrigerant from the second condenser, while all refrigerant from the compressor outlet flows through the first condenser that is in heat exchange relation to the evaporator.
