A simple vapor compression cycle uses ammonia as a refrigerant. The vaporizing and condensing temperature are -20°C and 35°C, respectively. The system is to be used in producing 10,000 kg of ice at -15°C from water at 25°C in 25 hours. The specific heat of ice is 2.094 kJ/kg-K and the heat of fusion is 335 kJ/kg. Assume that there are 30 percent losses of the heat to be absorbed from the water. Compute the heat rejected in the condenser in kW. (Use h₂ = 1735 kJ/kg)
