Water-to-water heat pumps are recently being employed to produce hot water, in-stead of gas water heaters. a water-to-water vapor compression heat pump cycle using 134-a as a working fluid operates between pressure limits of 200 kpa and 1600 kpa to produce hot water in winter. assume the isentropic efficiency of the compressor to be 85 percent determine the energy required to produce 100 gpm of hot water for 4000 hours of operation per year. what is the maximum temperature at which hot water can be produced? note: there should be at least 10°c of temperature difference between the water and the refrigerant fluid in the evaporator and condenser of the heat pump at inlet and exit of each device.
