ÂIf you do not expect the outdoor temperature to exceed 43C, then disregard the 3rd inflection. If high outdoor temperatures are expected then try using the table objects to model performance. See Table:TwoIndependentVariable.

Great, Thanks. Also, Jim, I have a VRF system (Mitsubishi City Multi, Simultaneous Heating and cooling with heat recovery outdoor unit). The performance curves are different than I came across before, it have three diversion, see attached (different than the one found in the publications of  R Raustad). Do you know how to model these performance curves to get a linear, quad or cubic fit equation?
ThanksKindest RegardsWasee,
