How much power do the comp add to the system?

[taz24]

COP is the ratio of the heat removed in KW to energy used in Kw, I am unsure how this relates to energy added to refrigerant could you clarify?

Another way of looking at it is this..

COP is a calculation that needs working out and
quite a few factors can effect COP, but it only deals with heat energy imparted
into the refrigerant (Enthalpy)

EER takes into account all the running costs of the system in KW so if you use 3 KW
in power and you get 12 KW of heating you divide 12 by 3 and the EER would be 4...

Or 3 KW in power and 9 KW of cooling = 9 divided by 3 = 3, EER would be 3.

EER is used to find out how efficient the system is in real life not just on paper.

Hope that helps
