If 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. On 7/2/2015 10:09 AM,

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? -- Richard Raustad Florida Solar Energy Center 1679 Clearlake Road Cocoa, FL 32922 Ph: (321)638-1454 http://www.fsec.ucf.edu/en/ Program Director Electric Vehicle Transportation Center http://evtc.fsec.ucf.edu/ __._,_.___ Posted by: Richard Raustad <rraustad@xxxxxxxxxxxx> Primary EnergyPlus support is found at: http://energyplus.helpserve.com or send a message to energyplus-support@xxxxxxxx The primary EnergyPlus web site is found at: http://www.energyplus.gov The group web site is: http://groups.yahoo.com/group/EnergyPlus_Support/ Attachments are currently allowed but be mindful that not everyone has a high speed connection.
