A refrigerator working on an ideal closed reverse Brayton cycle operates between 100,000 Pa and 1,000,000 Pa. Air flowing at 0.15 kg/s is taken from a cold chamber at -10°C. Before entering the expander, the air is cooled to 50°C. The air undergoes isentropic compression and expansion. a. Sketch the complete schematic diagram of the system (include labels). Sketch the P-V and T-S diagram of the system. c. Solve for the Heat rejected in the cooler in kW d. Find the Refrigerating Capacity in kW b.
