Abstract
A high-efficiency, enhanced, generator-absorber heat exchange (EnGAX) cycle, particularly useful in gas-fired, air-cooled absorption heat pumps, increases the heat output of the absorber in the temperature overlap range with the generator to equal the heat usable by the generator. This is accomplished by establishing a solution pathway from a portion of the absorber in the temperature overlap region to a portion of the generator in order to increase solution flow in the high temperature regions of the absorber and generator. Further improvements in cycle efficiency are obtainable by increasing the operating pressure of the absorber.
