Abstract

This research is about the efficiency of mini type shell heat exchanger in a car air conditioning system. Mini type Shell heat exchanger was used in this experiment by implying heat exchanger in car air conditioning system. Compressor will need less power in order to compress the air. Material used in this experiment was aluminum alloys after consideration of selection material. In this research, Proton Wira’s air conditioning system is used for the experiment. During the experiment with heat exchanger installed, the temperature reading has been for 10 minutes were taken and been repeated with different engine rotational speed. Data from the experiment has been calculated and analyzed. From the experiments, the highest value of Coefficient of Performance (COP) was 3.40 without heat exchanger installed and at 1000 RPM engine rotational speed. Meanwhile, the highest value of Coefficient of Performance improvement by using shell tube heat exchanger was 33.96%.In addition, the value of fuel consumption also taken during conducting the experiment. The data shows that, the fuel consumption increased when engine rotational speed increasing.
