A refrigerator using R-12 as the working fluid keeps the refrigerated space at ?16? in an environment at 27?. You are asked to upgrade this refrigerator by replacing R-12 with the ozone-friendly R-134a. What changes in the pressure levels would you suggest in the new system? How do you think the COP of the new system will compare to the COP of the old system?

A commercial refrigerator with refrigerant 134a as the working fluid is used to keep the refrigerated space at TL = -35°C by rejecting 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 50°C and leaves at the same pressure and 41.3°C. If the compressor consumes 3.3 kW of power, determine (a) the mass flow rate of the refrigerant, (b)...

A refrigerator is running with tetrafluoroethane (R1-34a) as the fluid and working based on the following cycle. Saturated vapor at -12oC is entering the compressor and leaving it at 40oC. The superheated vapor after the compressor then condensed at constant pressure to saturated liquid, which ethers the “Joule-Thompson” throttling valve and back to the initial pressure. Assume your system is operating ideally, with a cooling load of 0.2 kW (200 J/s). (a) Draw the cycle on the P-H diagram and...
