Abstract

The aim of this research was to examine performance enhancement of air conditioning with refrigerant temperature reduction before entering the condenser using heat exchanger storage tank. The experimental unit consisted of a vapor compression of 3.52 kW (12,000 BTU/hr) capacity with R-22 refrigerant and air cooled condenser. This study was divided into two experimental systems – the system without the heat exchanger storage tank and the system with the heat exchanger storage tank. Considering the system with the heat exchanger storage tank, the results showed that the refrigerant temperature at the compressor outlet passing through the heat exchanger storage tank decreased at 11.03 oC while the refrigerant temperature at the evaporator outlet passing through the heat exchanger storage tank increased to 5.63 oC. Nevertheless, comparable results between the system without the heat exchanger storage tank and the system with the heat exchanger storage tank indicated that the heat transfer rate of condenser increased to 12.11 %, reduced power consumption by up to 3.10 %, and the highest coefficient of performance with an increase of 15.38 %.
