Presently, the reduction in energy consumed by an air conditioner working on a vapor compression refrigeration cycle is a major issue. Application of evaporative cooling on a small-scale refrigeration and air conditioning system is limited due to its larger size and economy. In the present work, porous wick cloth is used on the condenser tube which is combined with direct evaporative cooling. Evaporation of fluid entrapped in the pore of wick cloth increase the heat transfer rate. The effect of evaporative cooling of the condenser on the performance of the air conditioner is experimentally investigated. The result shows about 32.4% enhancement in COP with a maximum ambient temperature of 35°C and 10-11% reduction in energy consumption and relative humidity about 21-26%. Refrigeration effect increased up to 30.6% with respect to the water cool condenser.
