First time here? Check out the Help page!
for my project in DesignBuilder i used the VRF system in the simple HVAC but when i stimulate the project i get some confusings results so as you can see in the image the VRF consume electricity but i get 0 KWH the cooling and heating should be in the electricity column not the distrect cooling/heating column C:\fakepath\Capture.PNG
Designbuilder "Simple HVAC" option uses the EneryPlus Ideal Loads object where the loads are considered to be met directly without use of HVAC equipment through a district heating/cooling system. EnergyPlus displays the unprocessed loads under 'District heating' and 'District cooling' at Summary tab ( Simulation screen).
To model the VRF equipment in detail you will need to use the "Detailed HVAC" model option. As a starting point I suggest to use one of the VRF HVAC templates. For more information see DesignBuilder Program Help.
i appreciate your answer i did what you've told me but when i get to the stimulation part this is what i get : Program Version,EnergyPlus, Version 8.9.0-40101eaafd, YMD=2020.09.22 10:20, * Severe * Regular expression "Etage1:Client1 Unité intérieure DRV" for variable name "Zone VRF Air Terminal Total Cooling Rate" in input file is incorrect * ~~~ * invalid UTF-8 * Fatal * Error found in regular expression. Previous error(s) cause program termination. ...Summary of Errors that led to program termination: ..... Reference severe error count=1 .....
Could you confirm that you are using the latest DBv6.1.6 release? This looks like one issue identified in v6.0 that has already been fixed.
i'm using designbuilder v6.1.0.006
I can confirm that this fix has been made after v6.1.2.009.
