Problem 2 (30 pts): Consider a two-stage vapor-compression refrigeration system operating between the pressure limits of 1.5 MPa and 150 kPa with refrigerant-134a as the working fluid. The refrigerant leaves the condenser as a saturated liquid and is throttled to a flash chamber operating at 0.45 MPa. The mass flow rate of the refrigerant through the low pressure compressor is 0.15 kg/s. Assuming the refrigerant...

Problem #4 (20 points) A commercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -30°C by rejecting its waste heat to cooling water that enters the condenser at 18°C at a rate of 0.25 kg/s and leaves at 26°C. The refrigerant enters the condenser at 1.2 MPa and 65°C and leaves at 42°C. The inlet state of the compressor is 60 kPa and-34°Cand the compressor is estimated to gain a net heat of...
