[Equest-users] Converting Heat Pump COP to EIR

[Walson, Kristy]

Hi Kathryn,

This is what we use:

EER adjusted = EER/(0.9585-0.01217*EER)

The conversion for EER to COP is:  COP = EER/3.412.

Subject: [Equest-users] Converting Heat Pump COP to EIR

Everyone, is there a relationship written down somewhere that removes fan energy from a heat pump COP value to develop a heating EIR?  Something like the DX cooling EER equation that removes fan energy from EIR  cooling values? It looks like the eQuest wizard is doing something like that when a heat pump heating COP is entered, but I am not sure what.
