An investigation is underway to develop air-to-air, gas fired, absorption heat pumps of higher efficiency, by the use of one of the advanced absorption cycles. The program is directed toward residential size equipment. The generator-absorber heat exchange cycle was found to be significantly more practical for the application than others. A preliminary cost estimate indicated the potential equipment price to be competitive with existing heating plus cooling equipment. Experimentally, a breadboard test unit reached its goal of a cycle coefficient of performance of 1.9 in heating mode at the 47/degree/F (8.3/degree/C) ARI test conditions. Outdoor testing of an assembled heat pump and development of components and a prototype heat pump are under way. A related investigation of new refrigerant/absorbent combination determined that the fluid has improved performance capabilities but serious corrosion problems. 4 refs., 8 figs.
