an absorption-cycle heat pump, however, has no moving parts and requires only heat at fairly low temperatures to operate. ... Technicians have been working on solar-driven absorption-cycle heat pumps for over a decade, but the hang-up has been that the best COP's have only been about 0.7, requiring a singledwelling...

The various processes of the vapor absorption cycle are similar to the one in vapor compression cycle, only the method of compression of the refrigerant is different. In vapor absorption system ammonia is used as the refrigerant, which has very high affinity to dissolve in water. ... Various Processes of Vapor Absorption Cycle...

Above shows the schematic arrangement of the actual vapour-absorption cycle and figure below presents its thermodynamic cycle on the hr diagram. The system consists of generator G, analyser AN, dephlegmator D and condenser C on-the high pressure side, and Evaporator E and absorber A on the low pressure side.
