Awindow-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 14 bar leaves the condenser. the compressor has an isentropic efficiency of 70%, and refrigerant exits the compressor at 14 bar.
determine the compressor power, in kw, the refrigeration capacity, in tons, and the coefficient of performance.
