CS-2009 EAp2: Minimum Energy Performance
Goodmorning,
i haven't understood how to consider the performance of the baseline's chiller: is it enough to consider a costant COP/IPLV ( tab. 6.8.1) or do i need a performance curve?
Thank you.

Hello Fabio,
I think it is enough.
90.1 requires that the software has the capability for the chiller to follow a performance curve, not that you need to enter one for the baseline. So you enter the COP/IPLV and the IPLV is the part-load efficiency based on the weighted average performance at various load capacities. Not certain without some more digging but I have assumed that the software creates a curve based on the COP and IPLV entered.
I'll check around and let you know if I am not accurate or someone else feel free to correct me.

To be more accurate the software would typically use a default curve adjusted to the COP/IPLV.
