Awindow-mounted air conditioner supplies 19 m3/min of air at 15 oc and 1 bar to a room. air returns from the room into 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, 10 oc and exiting at 9 bar. saturated liquid refrigerant leaves the condenser. assuming the compressor has an isentropic efficiency of 70%, determine: (a) the mass flow rate of refrigerant in kg/min,(b) the compressor power, in kw,(c) the refrigeration capacity, and(d) the coefficient of performance.
