The commonly used air conditioning system is the air conditioning system with vapor compression cycle. However, vapour compression cycle has an operation problem, which is the high energy consumption caused by air cooled condenser type. The condensors disadventages is temperature will increase when ambient temperature increases, it reduced the heat rejected by condenser. This studies used evaporative cooler moduleon condenser inlet to reduce the entering air temperature. The module efect on standard vapour compression cycle performance was tested using experimental methods by testing the effect of water discharged (0.88, 1.04, 1.2 L/min) with the power input.

The hybrid air conditioning systems can improve the energy efficiency by recovering waste heat of condenser that can be useful for various purposes. There are many experimental studies about this system which aimed to investigate and improve the energy efficiency. This experimental study aims to investigate the effect of cooling loads to system temperatures of hybrid air conditioning with trombone coil type of dummy condenser using 1/4″ diameter of copper pipe as water heater.
