Abstract: Air conditioning of automobile is essential for modern luxurious life. Today’s automobile air conditioning system is based on vapour compression refrigeration cycle and refrigerant R134a is used for this purpose. In this paper Lithium Bromide-water, Aquaammonia and Lithium Chloride -water refrigeration systems is run by waste exhaust heat or low grade energy of four cylinder four stroke diesel engine situated at mechanical department at Rajeev Gandhi technical university Bhopal. The capacity of refrigeration system is one ton and five litres kirlosker diesel engine is used for this purpose . A common counter flow shell and tube type generator or heat exchanger is used for all three vapour absorption refrigeration systems. The performance of all refrigeration systems depends on performance of diesel engine exhaust. This automobile air-conditioning system is run by waste heat or low grade energy, required minimum maintenance, used environment friendly refrigerants and reduce the mileage of the vehicle.
