The important thing to consider is that eQUEST?s definition of EER may not match the ARI-rated EER as the fan power and compressor power are usually separated in eQUEST whereas the fan power and compressor power are both included together in the ARI-ratings. This is where the more complicated conversions are coming from, as explained in detail in the RMI document linked by David.
All the best,
Daniel

Thanks Siddharth,
I did browse through this link but could not find the attachment that the
user had mentioned about.
I am looking for the source of the co-efficient; COOLING-EIR = (1/EER -
*0.012167*) / ((1 / 3.413) + *0.012167*)
Jayant, see if this helps ? search for ?EIR? and the section will come up:

Thanks David,
This document is helpful for my purpose of analysis.

Thank you Paul,
This is exactly what I was looking for. Spot on!!

EIR = 1 / COP
EIR = 3.412 / EER
EIR = (kW/ton) * (3.412/12)
