A company wants to design a vapor-compression cycle heat pump that uses ammonia 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 0.120 kg/s and exits as a saturated liquid. The compressor has an isentropic efficiency of 85.0%. Determine

a. The coefficient of performance of this system.

b. The amount of heat (in kW) transferred from the cold to the warm region.
