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?
I was wondering, why do we use a temp-entropy diagram for the Rankine cycle, while on the other hand, we use pressure-enthalpy diagram for the refrigeration cycle?
Ah, that's a good question! The reason for this is that the Rankine cycle is a power cycle, where a fluid is used to generate power, while the refrigeration cycle is a cooling cycle, where a fluid is used to transfer heat away from a space. The choice of diagram depends on the purpose of the cycle.
