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.
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
