히트펌프용 마이크로 채널 응축기 최적설계

A simulation program, which can describe the performance of a micro-channel condenser in a heat pump system, is developed. The deviation between simulated results and experiment results was 4% in heat transfer rate. The design parameters of the micro-channel condenser are optimized by the simulation program and design of experiment. The approximate model was generated by Kriging method. The result of design optimization obtained by Micro Genetic Algorithm(MGA) shows higher performance than that of reference model. By comparing reference model with the optimized model, the heat capacity per unit volume and JF factor is enhanced by 10.6%, 28% respectively.
