Jakob has recently purchased a mini fridge for his office to keep his lunch cool at work. He wants to calculate the a) isentropic efficiency and b) the second law efficiency of the refrigerator's compressor. After performing the necessary measurements, he determines that the refrigerant used is R-134a and enters the compressor at 100 kPa and 0°C. The refrigerant is then compressed adiabatically to 800 kPa and 80°C with the power meter reading 600W. He also noted that the kinetic and potential energies can be ignored and surrounding air temperature was 28°C.
