A large refrigeration plant is to be maintained at 10C. It requires refrigeration rate of 150kW. The condenser of the plant is to be cooled by liquid water, which experiences a temperature rise of 10C as it flows over the coils of the condenser. Assuming the plant operates on an ideal vapor-compression cycle using refrigerant R134a between the pressure limits of 100 and 700kPa, determine the following: (1) Using didactic sketches, evaluate the operating principles of a refrigeration system (2) the mass flow rate of the refrigerant. (3) the power input to the compressor. (4) the mass flow rate of the cooling water. (5) The coefficient of performance for the ideal cycle operating between 100 and 700KPa using thermodynamic tables. (6) The coefficient of performance for the ideal cycle operating between 100 and 700KPa using the p-h chart. (7) Illustrate the contradiction between refrigeration cycles and the second law of thermodynamics
