Abstract

Suction-Jiquid heat exchangers are most often used in the vapor compression cycle to exchange energy between the cool gaseous refrigerant leaving the evaporator and wann liquid refrigerant exiting the condenser. These device improve refrigeration system performance and it is a proven refrigeration system component for greater efficiency. This research study about the heat exchanger effect in term of Coefficient of Perfonnance (COP) in a car air conditioning system. Air conditioning system of Proton Wira is used for the experiment. The experimental with and without the presence of a suction-liquid heat exchanger in the car air conditioning system are presented and analyzed. A comparison of COP that are calculated from the experimental result between the system with and without the presence of heat exchanger is enclosed. An increase of the coefficient of performance has been found using the suction-liquid heat exchanger. The suction-liquid heat exchanger improved COP of the refrigeration system up to 24%.
