Refrigerant COP Comparison Question
Refrigerant COP Comparison Question
(OP)
For a given ideal refrigeration cycle with an evaporator temperature of -20 deg C and condenser temperature of 40 deg C, what is responsible for the COP differences between R-12, R-22, and R-410A? After setting it up in EES, I get COPs of 3.174, 3.149, and 2.915, respectively. I am trying to understand what it is about the thermophysical properties of R-12 that make it a better choice (efficiency-wise) than the other two in this particular cycle. This question is purely theoretical.





RE: Refrigerant COP Comparison Question
You probably know this book if you use EES. I'm glad more people using EES. Is this a homework by any chance? Are you at UW MAdison by any chance?
