Homework Statement
Does Coefficient of Performance for refrigeration cycle depend on refrigerant used? In reference to vapor-compression cycle
Homework Equations
COP = [itex]\frac{1}{\frac{T_{H}}{T_{L}}-1}[/itex]
The Attempt at a Solution
I am split in my answer to this question.
I understand that the COP isn't a material property of a refrigerant, but rather a measure of the performance of the refrigeration cycle. To increase coefficient of performance, we can minimize the gap between T_H (condenser) and T_L (evaporator). So in this case, it seems the only thing limiting the COP is the rate of heat removal (from load) by the evaporator and the rate of heat rejection from the system by the condenser.
However, would using different refrigerants allow for higher values of T_H and T_L to be removed or rejected?
