A refrigerator with a cooling capacity of 5 ton uses ammonia as the working fluid. The condenser and evaporator maintain a pressure of 1500 kPa and 200 kPa respectively. The compressor has an isentropic efficiency of 80%. If the vapor leaving the evaporator is superheated by 5°C and the liquid leaving the condenser is supercooled by 5°C, determine:
a) The power input to the compressor

b) The mass flow rate of ammonia

c) The COP of the refrigerator

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...
