Why do we use a temp-entropy diagram for the Rankine cycle, while on other hand we use pressure-enthalpy diagram for the refrigeration cycle?
Okay. And what about the pressure-enthalpy diagram for the refrigeration cycle? Why is that useful?
The pressure-enthalpy diagram is useful for the refrigeration cycle because it can show the temperature and pressure of different points in the cycle, which can help to determine the state of the refrigerant. It can also show the amount of work done and heat absorbed or released at each point, which is important for understanding the performance of the cycle.
