I disagree with all of you,

There is no way to convert HP > TR and COP will not add much,

Its all in the evaporating temperature, head pressure and ambient temp. { and that is if, lets say, the system has been designed perfect}

A 10 HP compressor [maneurop 124] will give output of 7.74 KW at -30° evaporation temp and 42.135 KW at 10°C evaporation. Now, thats only at 27°C ambient...... It will be a different story altogether when the ambient will rise to 45°C.

So?????????? How do you convert now?
