Problem: A refrigeration cycle using R123 operates between 25 psiA and 75 psiA.
Given: 25 psiA and 75 psiA; 25 psiA; 25 psiA saturated we got 24
Approach: Refrigerant enters the compressor with 20 degrees of superheat and leaves the condenser as a saturated liquid.
Calc: So the difference in the enthalpy as we go through the compressor from state 1 to state 2 on the refrigeration cycle.
Calc: So as a reminder, we can draw the refrigeration cycle and really the best way to do this problem is to draw that cycle on the a...
Result: Now the question is what's the enthalpy at state one so there's two ways to go about that the first is to come vertically up or suppose you could g...
