Ideal Vapor Compression Cycle

The Ideal Vapor-Compression Refrigeration Cycle . Most compressors do not work well on two-phase mixtures. Solution: Completely vaporize the refrigerant in the evaporator. Turbines are not designed to handle vapor liquid mixtures. Solution: Replace the turbine with an expansion valve.

A heat pump that operates on the ideal vapor compression cycle with refrigerant-134a is used to heat a house and maintain it at $26^{\circ} \mathrm{C}$ by using underground water at $14^{\circ} \mathrm{C}$ as the heat source. Select reasonable pressures for the evaporator and the condenser, and explain why you chose those values.

9-3-2 [rankine-10MPa] Steam is the working fluid in an ideal Rankine cycle . Saturated vapor enters the turbine at 10 MPa and saturated liquid exits the condenser at a pressure of 0.01 MPa. The net power output of the cycle is 150 MW. The turbine and the pump both have an isentropic efficiency of 85%.

Process 1-2: vapor refrigerant is compressed to a relatively high temperature and pressure requiring work input. Process 2-3: vapor refrigerant condenses to liquid through heat transfer to the cooler surroundings. Process 3-4: liquid refrigerant expands to the evaporator pressure. The processes of this cycle are Two-phase liquid- vapor mixture. 5.
