Hi,
how can i do if my project's heat pump /chiller manufacturer doesn't provide efficiencies AHRI-rated?
I need to model with COP and EER at nominal and part load tested under US AHRI codes.
Does an alternative method exist to compare efficiencies calculated under european codes to US AHRI test procedures?
Thanks in advance,
Alessandro Zuanon

I would first compare the rating conditions of the European codes to the AHRI efficiencies to confirm that they are in fact different (after converting units of Celsius to Fahrenheit, for example). If they are different, then I would check if the energy modeling software has an option to use the European efficiencies as an input. As a last resort, you could simply model the heat pump chiller at the ASHRAE 90.1 minimum efficiency requirement.
