Abstract: Most current Sports Utility Vehicles in India use fixed or variable displacement type piston compressors in air conditioning system which consumes a lot of power from engine. The AC compressor is the highest consumer of engine power among all the air conditioning system components. It is evident that any effort of reducing power consumption will not have fruitful result without reducing compressor power consumption. The conventional piston compressors are not only higher in weight, its volumetric efficiency is less too. The objective of this work is to derive analytical methodology to select a suitable Scroll Compressor without having any compromise on cooling performance of the vehicle and to articulate benefits by giving objective values for weight reduction, parasitic load reduction and above all fuel economy improvement of the vehicle. In cognizance of the Scroll technology, in the current work piston compressor has been replaced with an energy efficient Scroll compressor of an existing SUV vehicle to achieve weight reduction of 2 Kg, power consumption reduction up to 0.4 Kwatt which has resulted in fuel economy improvement by 0.5 Kmpl. Unlike previous works done on this topic the compressor selection procedure can be applied to all kinds of passenger vehicle to achieve similar objectives.
