Homework Statement
The COP for heat pumps and refrigerators achieved in the industry is almost 50% of the Carnot limit. Make estimates for the following case:
For refrigerator to achieve -10°C in the freezer area with an external temperature of 25°C
Homework Equations
COP for refrigerator = T(low) / [T(high)-T(low)]
The Attempt at a Solution
Using this equation, I find that the COP is 7.5, but this seems high. Where have I made a mistake?
