A window-mounted air conditioner supplies 19 m3/min of air at 22℃, 1 bar to a room. Air returns from the room to the evaporator of the unit at 29℃. The air conditioner operates at steady state on a vapor-compression refrigeration cycle with R134a entering the compressor at 7 bar, 28℃. Saturated liquid refrigerant at 12 bar leaves the condenser. The compressor has an isentropic efficiency of 75%, and refrigerant exits the compressor at 12 bar. Determine the compressor power, in kW, the refrigeration capacity, in tons, and the coefficient of performance.
