Hi guys

This must be my 1st post, at least for a few years

Is there somewhere a way to calculate what power an evaporator or a condenser is?

For instance, I have a condenser 4/20x300 fin 2,5 with a 16W/D250 (27°) fan.

How can I covert this to f.i. 1/4Hp?

It is a troubling question for me, first of all because I am not a refrigeration engineer but a mechanical engineer
and then 'cause I still haven't figured out what f.i. (again) an 1/4Hp refrigerating power means for a compressor, the refrigerating power stated by the manufactures in Watts does not compute!!!!

Thank you in advance!!!!
