Hi everyone I am trying to model a VRF system in OpenStudio with model AirConditioner:VariableRefrigerantFlow. I found many choices for the curve of cooling part, as well as for heating part: My question is if there is some visual or practical guide to choose the curve for a customized VRF system? by default, all the curves seem to be the "6". Or what's the difference amongst these curves in each choice?

Thanks in advance
