Task 3 An ideal vapor-compression refrigeration cycle that uses refrigerant-134a as its working fluid maintains a condenser at 800 kPa and the temperature of the evaporator is -15 C. Given 300 kW of cooling load, determine the following: 1. Construct didactic sketches, showing the operating principles of a refrigeration system. 2. When you select a refrigerant for a certain application, what qualities would you look for in the refrigerant? 3. Estimate the reversible COP values, if the low and high medium temperature are as for the evaporator and condenser. 4. Determine the Refrigeration effect (RE), heat of compression (HOC), and heat of rejection (HOR) and their corresponding rate/power values in kW. 5. Estimate the COPR using thermodynamic tables 6. Calculate the COPR using the P-h chart and show the refrigeration cycle on the p-h chart. 7. Discuss the difference between your answers in 4 and 5 above and which one do you think is more accurate.
