Improving the performance of air conditioning system experimentally by a new type of heat pipe heat exchanger

Abstract

The air conditioning system efficiency is measured by it is coefficient of performance (COP). Higher COP means better system. However, the improving of COP is not an easy work since it linked the heat rejected by the system to power consumed by mechanical part in system, especially the compressor. In this study, a smart employing of heat pipe heat exchanger (HPHE) is used to reduce the power consumed by compressor through super heating the refrigerant vapor pre-enter the compressor and improve the cooling capacity. The results show that using (HPHE) improves the COP of the system by 10% compared to other conventional system.
