You have been hired as an industrial spy and have been asked to learn more about the Freeze-Fast refrigeration plant in Salt Lake City. The plant uses r-134a as the working fluid. Sneaking into the plant and looking at the pressure gauges, you note that one part of their cycle operates at about 50 kPa, the other part operates at 1.8 MPa. You also note that an expansion valve is present as part of their system. From the above information, please determine the coefficient of performance of the refrigeration plant if everything operates ideally. Approximate solution: COP = 1.
