The condenser of a room air conditioner is designed to reject heat at a rate of 15,000 kJ/h from refrigerant-134a as the refrigerant is condensed at a temperature of 408C. Air (cp 5 1005 J/kg?K) flows across the finned condenser coils, entering at 258C and leaving at 358C. If the overall heat transfer coefficient based on the refrigerant side is 150 W/m2?K, determine the heat transfer area on the refrigerant side.
