Abstract: The objective of this research was to study the Coefficient of Performance (C.O.P.) of split type air conditioner using condensed water from evaporator to exchange heat with refrigerant at condenser outlet for reducing temperature of refrigerant before entering expansion device. The research was conducted on split type air conditioner which having cooling capacity 12,000 BTU/h at actual operation. The refrigerant was R22. Room temperature was controlled at 25°C. The results of this research were found that refrigerant temperature was decreased at inlet expansion device and outlet compressor. On the other hand, refrigerant temperature was increased at evaporator outlet and compressor inlet. Pressure of the refrigerant was decreased at compressor outlet and condenser inlet, whereas, increased at before compressor and evaporator. The average C.O.P. of the system was increased by 3.79% while the system was installed with device collecting the condensed water from evaporator to reduce refrigerant temperature at condenser outlet.
