Abstract

Living in the Asia Pacific and other tropical countries presently with high temperatures and humidity, people tend to look forward to better lifestyle with technology which is more environmental friendly and energy efficient. Two-phase ejector as expansion valve in air-conditioning system has been studied since 1900s for a better performance of the system. This study aims to investigate the performance of an improved ejector air-conditioning system as compared to that of the conventional air conditioning system. The conventional air-conditioning system and an improved ejector air-conditioning system are studied experimentally using R22 as the working fluid. The coefficient of performance (COP) of both air-conditioning system were conducted and analysed based on the results collected from the experiments. It was found that the improved ejector air-conditioning system has COP of 12% - 14% higher than that of conventional air-conditioning system.
