Optimization of Automotive Refrigeration Systems Using Load Maps 971801

Load maps show the relative frequency of ambient temperatures and driving states divided in several classes. They are a means to determine the yearly average of performance or power consumption of an automotive air-conditioning system. The load maps for California, Central and Southern Europe are used to illustrate the differences in power consumption. The possible power savings using an evaporator control concept are discussed and assessed as an example for an new technique which has low effect at high load but large impact at part load conditions.
