A special high-temperature vapor-compression cycle heat pump for a spacecraft is to be designed that uses water as the working fluid. The evaporator is at 100.°C and the condenser is at 300.°C. The refrigerant enters the condenser as a saturated vapor at 1.80 kg/min and exits as a saturated liquid. Assume that 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 from the cold to the warm region.
