Automobile air-conditioning is a necessity of present life. vapour compression refrigeration cycle (VCRS) used in modern automobile and refrigerant 134a are available in automobile. The compressor of automobile air-conditioning is run by engine crankshaft, which reduces the mileage of the automobile. This project present a vapour Absorption air conditioning system (VARS) generator is run by exhaust waste heat of internal combustion engine. A shell and tube counter flow type heat exchanger is used as a generator of absorption refrigeration system This system is saves the break power that is utilized in the compressor in a vapour compression refrigerat ion system (VCRS) Also reduce ozone depletion potential (ODP) and Global warming Potential (GWP).
