Performance curves are created from manufacturers data for the installed/simulated system. Once you have the data, use the curve tool provided with E+ in folder C:\EnergyPlusV9-1-0\PreProcess\HVACCurveFitTool or see this document for a description of how curves are created. This is for VRF systems but creating curves are basically the same. http://www.fsec.ucf.edu/en/publications/pdf/FSEC-CR-1910-12.pdf
Dear all,
I want to simulate the energy demand of a Supermarket. As I want to place it in warm and humid climates I won't need heating but cooling.
I am using the energyPlus Sumpermarket_Detailed.idf example file and size it down to my Prototyp (800 m²), where they are applying an DX Cooling Coil. Now I want to change the capacity so that it fits to my cooling load. Where or how do I get the performance Curves? They are using a temperature curve, a flow fraction curve an Energy Input Ratio Function of Temperature Curve and an Energy Input Ratio Function of Flow fraction curve. How can i calculate them? Are those curves already those describing the compressor and condenser of the AC System?
I would like to compare an average system using still R22 as a refrigerant with an AC using R290. How do I get the curves for such a system?
Thank you in advance for your help.
Kind regrads
Lara
