QUESTION: Problem 29P
The low temperature of a freezer cooling coil is –15°C, and the discharge temperature is 30°C. What is the maximum theoretical coefficient of performance?
ANSWER:
Solution 29P
Step 1 of 2:
The cold temperature of a freezer TL and the discharge temperature TH are given. We are going to find the maximum theoretical coefficient of performance.
The cold temperature TL = -15°C = 258 K
The hot temperature TH = 30°C = 303 K
