A cooling rate of 120 kW is needed to maintain a storage facility at -18'C. The condenser of the
refrigeration system utilizes a cooling liquid water. The liquid water leaves the condenser after
experiencing 10'c temperature rise. The refrigeration system uses refrigerant-134a and
operates between the pressures of 120 and 800 kPa. The refrigerant leaves the evaporator as a
saturated vapor and leaves the condenser as a saturated liguid. Determine the lowest possible
power input to the compressor in kW.
