Abstract
An apparatus and methodology are provided for advantageously increasing heat transfer between the evaporator/oil separator ('accumulator') and condenser of a refrigerant recovery/recycling system, to increase the efficiency of the system and to simplify the system. Embodiments include a refrigerant recovery/recycling device comprising a compressor having a suction inlet and a discharge outlet; an accumulator fluidly connected to a refrigerant source and to the compressor suction inlet; a recovery tank fluidly connected to the compressor discharge outlet; and a heat exchanger for transferring heat from the recovery tank to the accumulator, for raising the temperature of the accumulator and lowering the temperature of the recovery tank.
