A vapor-compression cycle heat pump has been developed that uses R-22 as the working fluid. The evaporator is at 0.00°C and the condenser is at 30.0°C. The refrigerant enters the condenser as a saturated vapor at 0.0800 kg/s and exits as a saturated liquid. The isentropic efficiency of the compressor is 83.0%. Determine
a. The coefficient of performance of this system.
b. The power (in kW) required to drive the unit.
