A window-mounted air conditioner supplies 29 m³/min of air at 15°C, 1 bar to a room. Air returns from the room to the evaporator of the unit at 22°C. The air conditioner operates at steady state on a vapor-compression refrigeration cycle with Refrigerant 22 entering the compressor at 4 bar, 10°C. Saturated liquid refrigerant at 11.5 bar leaves the condenser. The compressor has an isentropic efficiency of 70%, and refrigerant exits the compressor at 11.5 bar. Determine: (a) the compressor power, in kW. (b) the refrigeration capacity, in tons. (c) the coefficient of performance.
