Mobile air –conditioning system efficiency become more important to improve fuel efficiency and reduce green housegas emissions, so internal heat exchanger(IHX) applications become necessary for R134a refrigerant air-conditioning system as well as anR1234yfrefrigerant air-conditioner. In this study, R134arefrigerant air-conditioning system was investigated with three different type of coaxial IHX. The experimental results showed three different types of IHX havethe similar cooling capacity, but spiral type IHX shows slightly better coefficient of performance(COP) than other type of coaxial type IHXs. Type 3 IHX increas COP about 0.5~1.5% and 0.9~1.0% than Type 1 IHX and Type 2 IHX respectively.
