Does anyone know if the EER to EIR conversion mentioned below applies to
chiller COP values? For instance, if chiller data lists a full load
efficiency of COP 3.1/EER 10.5, do we then apply the EIR conversion and
enter that into the eQuest chiller EIR space?

Also, does anyone have a way of extrapolating a partial load curve for
any cooling equipment that lists a full load EER and an IPLV EER? The
equation for IPLV is:

IPLV = 0.01A 0.42B 0.45C 0.12D

where

A = COP at 100% load and an ECWT of (85F)

B = COP at 75% load and an ECWT of (75F)

C = COP at 50% load and an ECWT of (65F)

D = COP at 25% load and an ECWT of (65F)

Unfortunately, I think I have too many variables and not enough data
