A window-mounted air conditioner supplies 19 m3/min of air at 15oC, 1 bar to a room. Air returns from the room to the evaporator of the unit at 22oC. The air conditioner operates at steady state on a vapor-compression refrigeration cycle with Refrigerant-22 entering the compressor at 4 bar, 10oC. Saturated liquid refrigerant at 9 bar leaves the condenser. The compressor has an isentropic efficiency of 70%, and refrigerant exits the compressor at 9 bar. Determine the compressor power, in kW, the refrigeration capacity, in kW, and the coefficient of performance.
