dc.description	Abstract The aim of this research was to study the air temperature reduction before entering the condenser by condensed water of evaporator passing through heat exchanger. 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. The heat exchanger was made of a copper u-tern bend tube with an external diameter of 6.35 mm, a length of 500 mm with 55 mm spacing between each tube. This copper tube bent into the shape with 7 turns. The results showed that the coefficient of performance was found to be 4.08, the power consumption of compressor of 866.25 W, and the heat transfer rate of condenser and evaporator were 4.40 and 3.54 kW, respectively. It also found that when the air flow passing through the heat exchanger, the average decrease of temperature was 2.1 oC.	en_US
