A food refrigerator is to provide a 15,000 kj/h cooling effect while rejecting 22,000 kj/h of heat. calculate the cop of this re
svp [43]
Coefficient of performance or more commonly known as COP is calculated through the equation,
                                 COP = ((T₂)/(T₂ - T₁)) 
where T₂ is the hot temperature and T₁ is the cold temperature. Similarly, these can also be,
                      COP = heat ejected / (heat ejected - heat provided)
 Substituting,
                     COP = 22,000 / (22,000 - 15,000) = 3.14
Thus, the value of the COP is approximately 3.14.
