Abstract
In the field of the air-conditioning equipment for vehicles, the conversion to HFO1234yf from R134a is considered in recent years. Furthermore, heating by HP is considered with the spread of a hybrid car, EV(s), etc. Under such circumstances, the demand to a high-efficiency heat exchanger is increasing, and the performance improvement of air-side which affects the performance of a heat exchanger greatly becomes important, especially. In this research, the optimization technique which used CFD and an experimental design method about corrugated louver fin mostly used with the air-conditioning equipment for the present vehicles for the purpose of optimization of the air side heat transfer characteristic of a heat exchanger was established.
