Your company needs to install a cold room which will maintain a temperature of -15 degrees operating in a room where the temperature is 20 degrees. A new member of staff has considered the specifications of two manufacturers and asked you to check their figures. Explain what your decision would be.
Company A : coefficient of performance 8.5
Company B: coefficient of performance 9.7
CoP = desired output / required output
The Attempt at a Solution
Does higher CoP simply mean that the efficiency of the cold room is higher?
I tried to use the temperature values given:
T(cold) / (T(hot)-T(cold)) = 7.37
