Abstract

In a heat activated heat pump apparatus having a generator, condensor, evaporator and absorber, a first coolant pathway through the absorber and condenser and a second coolant pathway through the evaporator. An ambient air heat exchanger and a second heat exchanger in heat exchange relation with the space to be cooled or heated are selectively interconnected with the first and second coolant pathways. In the improvement, rich liquor from the absorber is preheated by heat exchange with a portion of the interior of the absorber, with the weak liquor from the generator and with the refrigerant vapor from the generator.
