Abstract

Internal or suction line heat exchangers (IHX) are used in some car air conditioning systems with basic objective to optimize the liquescence process of the refrigerant before entering the expansion device. This purpose is achieved by exchanging thermal energy between the cool gaseous refrigerant in the low pressured suction line and the warm liquid refrigerant in the high pressured liquid line in the A/C system. These devices can have either positive or negative influences on the Coefficient of Performance (COP) of the car air conditioning system, depending on the working fluids, the operating condition and the configuration of heat exchanger. The finding from the experimental test indicated the COP of the system with adoption of IHX will be up to 7.92% increment than the system without adoption of IHX if rotational speed of engine was increased.
