FUEL ECONOMY POTENTIAL OF A COMBINED ENGINE COOLING AND WASTE HEAT DRIVEN AUTOMOTIVE AIR-CONDITIONING SYSTEM

An organic fluid engine cooling system combined with a novel jet-vapor-compression automotive air-conditioning system is considered as an alternative to conventional belt driven vapor compression systems added on to the water cooled power plant. The energy significance of accessory dead weight and engine drag is evaluated and the value of shifting from a prime shaft driven system to a waste heat recovery system is derived. Based on a single model year fleet equipped with the hypothetical heat recovery system it is shown that the annual energy cost of automotive air-conditioning usage could be reduced by more than 70%. The salient features of this novel Rankine bottoming cycle approach and some of its eccentricities are also described.
