Performance Evaluation of Air Conditioning Systems Using Air Pre-Cooler

Abstract

Air conditioning systems contribute to the largest share of energy consumption in building sector. Increasing the coefficient of performance of air conditioner with air-cooled condenser is a challenging problem especially in area with very hot weather conditions. The aim of this study is to minimize the energy consumption and improve the performance of air conditioning systems utilizing condensate & water. Experimental investigation has been carried out to improve the performance of an air-cooled vapour compression system by pre-cooling air entering the condenser using condensate and water. A pre-cooler is incorporated on a 1.5 ton-cooling capacity window type air conditioning system to lower the air temperature entering the condenser sensibly. Performances of the air conditioning system with and without air pre-cooling are compared and recorded in the results.
