To improve the performance of cars i.e enviromental quality, fuel, economy etc. It is required to use of high technology research and design tools. One of the tool is Ansys. Whether it is the study of external flow or internal flow over the body. Ansys helps engineers to understand better about the physical flow processes, and in turn to design improved vehicles. Working with the software by choosing applications where it is difficult to check the validity of the results, so that the engineers can see the strength and weakness of given computation technique against the background of known, exact analytical solution. In today generation where new designs, speed, cooling system is mandatory in cars, likewise air condition is also necessary to provide cooling comfort in cars. As cars having air condition which is more likely vapour compression system which uses some amount of fuel which contains HCFC refrigerants, which contribute to depletion of earth's ozone layer. HCFCs are due to be phased out and are largely being replaced by ozone friendly HFCs. In replacement vapour absorption system is used which uses heat as a source in generator. Generator is a main component of vapour absorption refrigerator which replaces compressor as a main unit in cars. In this project thermal analysis of vapour absorption system is done. The different component of vapour absorption system which includes generator, condensor, evaporator, absorber are analised in ansys at different conditions, materials, and design model. Models being converted from 3 dimension to 2 dimension solid to be analyzed in APDL software where the different material of fins and tube is analysed according to the different conditions and effect of atmospheric air is taken into account.
