Abstract

This research is about the effect of heat exchanger in terms of Coefficient of Performance car air conditioning system. Suction-liquid heat exchanger are used in this experiment while for the material is used aluminum alloys after the consideration of selection material. In this research, Proton Wira’s air conditioning system is used for the experiment. The experimental with different lengths of suction-liquid heat exchanger and without heat exchanger are presented and analyzed. There are three different lengths of suction-liquid heat exchanger include in this report. A comparison of COP that is calculated between different lengths of suction-liquid heat exchanger and without heat exchanger is enclosed. An increase of COP has been found by using longer length of heat exchanger. The improvement COP of the refrigeration system up to 33.33% between the longer length of heat exchanger and without heat exchanger. Besides that, this research also includes the experiment for fuel consumption in car engine. The fuel that has been used is increase when the rotational speed increase.
