I am a beginner in the DB modelling and I have a simple question: considering the efficiency of cooling systems is expressed in EER (Energy Efficiency Ratio), why DB asks for the COP (Coefficient of Performance) as if it were a heating system?
For example, if I have a multi split system with EER=3.32 (cooling) and COP=3.9 (heating), should I find out a way to convert the EER to COP or it's just a "name issue" and I can insert the EER value (3.32) where it asks for the COP of the cooling system in the DB?
Thanks!
