A vapor-compression cycle heat pump using R-134a as the working fluid is to be designed for heating a house. The evaporator is to be buried in the ground below the frost line and consequently will remain at 14.0°C year-round. The condenser is to be inside a house and will operate at a constant 20.0°C. The refrigerant enters the condenser as a saturated vapor at 7.30 kg/min and exits as a saturated liquid. Assume the isentropic efficiency of the compressor is 91.0%. Determine

a. The coefficient of performance of this system.

b. The amount of heat (in kW) transferred into the house.
