A Carnot refrigeration cycle uses refrigerant-134a as the working fluid. The refrigerant evaporates at 120 kPa and condenses at 30ᵒC. The refrigerant changes from saturated vapor to saturated liquid in the condenser as it rejects heat. Determine the heat removal (kJ/kg) from the refrigerated space.
