Question

in mechanical refrigerator low temp coils are at temp of -13 degree celsius and compressed gas in condenser has a temp of 27 degree celsius . what is coefficient of performance?

Answer 1

Dear Student

T_hot = 27 C⁰
T_cold =-13 C<sup>0
Coefficient of Performance (COP)=$\frac{T_{hot}}{T_{hot}-T_{cold}}=\frac{27}{27-(-13)}=\frac{27}{40}=0.675$
