5/637839
Inventors:
Frederick Alexander Costello - Herndon VA
Assignee:

Abstract:
A conventional absorption refrigeration system is combined in series with a vapor compression refrigeration system to effect the improvement, which comprises compressing the vapor refrigerant from the evaporator before introducing it into the absorber and/or compressing the vapor refrigerant from the generator before introducing it into the condenser. One bypass permits direct operation as a vapor-compression refrigeration system. Bypasses also permit direct operation as an absorption system.
