An ice-making machine operates on the ideal vapor-compression cycle, using R-134a. The refrigerant enters the compressor as saturated vapor at 140 kPa and leaves the condenser as saturated liquid at 600 kPa. Water enters the ice machine at 13oC and leaves as ice at -4oC, while removing heat at 393 kJ per kg of water. Estimate the mass flow rate of the refrigerant and the power input to the ice machine for an ice production rate of 7 kg/h.
