An industrial scale refrigerator has R134a as the working fluid. The condenser operates on an isobar (that is, at constant pressure) with an exit temperature of 40 °C; the evaporator is at 4 °C. The mass flow rate through the cycle is 5.0 kg/s. The schematic of the cycle is given in the left panel of the figure below; the right panel shows the temperature-entropy (TS) diagram. a. What is the refrigeration rate (0.1? [10 marks] b. What work rate (power) does the compressor need? [10 marks] Use the tables for R134a as provided at the end of typed-up Lecture Notes 4 (on refrigeration & liquefaction). T 3 3 4 3 condenser throttle valve compressor 2 evaporator 2 A S
