Performance Improvement of Air Conditioning System using Applications of Evaporative Cooling: A Review Paper

Abstract

In present situation, reduction of energy consumption is necessary due to continuous increase in energy demand and reduction in global energy supply. Coefficient of performance of air conditioning system can be increased with evaporative cooled condenser in place of air cooled condenser. This paper presents a broad review of evaporative cooled condenser used in residential and commercial cooling systems. Evaporative cooled condenser increases the heat rejection process with the cooling effect of evaporation and therefore improve coefficient of performance. It is found by using evaporative cooling condenser, the power consumption can be decreased upto 20 % and coefficient of performance can be increased around 50%.

Performance Enhancement of Split Air Conditioner During Evaporative Cooling Application

“…In small-size residential air conditioners such as split-type air conditioners, air condenser performance drops down during the vapor compression cycle due to the increase of condensing temperature. It increases the pressure ratio across the compressor; thus, the compressor work increases, leading to more power consumption [10][11][12]. It is well known that when the temperature of condenser increases at each °C, the coefficient of performance (COP) of the refrigeration system decreases around 2-4 % [13].…”
