Comparation on Automotive Air-Conditioning Cooling Load Computation

The precondition of optimized designing of automotive air-conditioning system is accurate air-conditioning cooling load computation, while the current load computation is mostly estimated according to the experiences, and it is on the stage of exploring for the dynamic load computation. Three kinds of methods on load computation are discussed in this paper based on city model according to typical weather condition of Changchun with a car structure. It is indicated that the results of the dynamic load are lower than those of steady state load.
