Air Conditioning system of Automobile using Turbocharger

Conventional automobile air conditioning system draws power from the engine. The air conditioning system consumes quite a reasonable amount of fuel energy. This paper aims to utilize the kinetic energy of the exhaust gas from automobile engine as a prime mover for Air Conditioning system. This avoids the extraction of power from the engine. Turbocharger works on kinetic energy of exhaust gas. It is used for suction of fresh air from atmosphere to deliver at engine inlet. This function of turbocharger is used for circulation of refrigerant for air conditioning system of automobile. In this paper we have discussed various ways for using kinetic energy of exhaust gas for circulation of refrigerant. One of the way is that, turbocharger can be used itself as AC compressor by principle of centrifugal compression; else a separate AC compressor can be coupled with the turbocharger. This project validates the use of gas turbines as a power input for AC compressor. Third option is to use kinetic energy for generating alternating current which can be used for electric supply for AC compressor; else to get thermoelectric cooling. Also part cooling effect from AC system can be used as intercooler for the compressed air. Thus achieving regeneration system in automobiles itself. This brings out better use of exhaust gas. Thus it proves to be very helpful.
