Abstract

A absorption refrigeration system having cooling and heating modes of operation functions with a double-effect or "split" refrigeration cycle having approximately the same refrigerant concentration span in each cycle loop. The system includes a novel direct expansion combined evaporator and absorber assembly with improved heat transfer characteristics and with interchangeable liquid flows accomplished through actuation of a conventional reversing valve. Also, the system is provided with improved recuperative heat exchangers to further increase system energy conversion efficiencies.
