cold storages

Well, I don't know where to ask, so i put it here, if here isn´t the forum please send me to the right one hehehe.
It's there a way to evaluate (equipment efficiency) cold storage?. I actually use COP but i think that there's another way to evaluate. Thanks

Using only the COP would show a relative change in performance.

However, you also need to consider the cost of operation and when the expense of the electricity use occurs. If the electrical rates are cheaper in the evening, you may find advantages here also.

So, what I'm saying is; It is not only the COP but also the cost of operation and when it occurs.
