Abstract
This study deals with the performance investigation of vehicle air conditioning system under different heat load. The effect of different heat load on system temperature, system pressure, compressor work, cooling capacity and coefficient of performance was investigated. The heat load is simulated using electrical bulbs with the power range between 300 to 900 watt. In addition, R134a was used as refrigerant. The heat greatly affect the performance of air conditioning system. Meanwhile, the speed of compressor, speed of blower fan and ambient temperature is fixed. Measurements were taken during the 10 minutes experimental period for evaporator inlet temperature of air which 30℃. The data has been analysed in statistically and graphically by using Refprop. It seems that the result has risen up and fall regularly almost every parameter in this experiment which is not corresponding with the previous research due to some error. The result shows that the performance of the vehicle air conditioning system increase about 9.86% in 34℃ to 37℃ when the evaporator inlet temperature of air increased (heat load increase). Therefore, the best coefficient of performance of vehicle air conditioning system with different heat load is 4.57 at 37℃.
