DOUBLE EFFECT AIR CONDITIONING SYSTEM

摘要

An 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 (16) with improved heat transfer characteristics and with interchangeable liquid flows accomplished through actuation of a conventional reversing valve (78). Also, the system is provided with improved recuperative heat exchangers to further increase system energy conversion efficiencies.
