This question about " Electro-Mechanical Sysrems: Simple vapor compression cycle"

A simple vapor compression cycle works in a residential refrigerator and uses R-410a as a refrigerant. The evaporator temperature is − 20 ºC and the condenser temperature is 35ºC. Saturated vapor enters the compressor. If the refrigerant flow rate is 0.15 kg/s, calculate:

- Compressor power

- Rejected heat from condenser

- The COP of the cycle

- The increase in COP if an internal heat exchanger is used that causes the superheating of vapor to 0°C while subcooling the liquid refrigerant to 20°C.

An ideal vapor-compression refrigeration cycle is modified to include a counterflow heat exchanger, as shown in the figure below. Ammonia leaves the evaporator as saturated vapor at 1 bar and is heated at constant pressure to 5°C before entering the compressor. Following isentropic compression to 18 bar, the refrigerant passes through the condenser, exiting at 40°C, 18 bar. The liquid then passes through the heat exchanger, entering the expansion valve at 18 bar. If the mass flow rate of refrigerant...
