I have a new question when I saw a new chiller curve. It is the DOE2.2 chiller curve. I mentioned that DOE2 curve part load ratio (EIR_PLR) curve used to be a quadratic curve (DOE2.1E I guess). Then when try to convert the DOE2.2 water cooled electric chiller part load curve (EIR_PLR) to E+, I foud it is now defined as "BI-QUADRATIC-RATIO&DT" curve which seems to be new in DOE2.2.
