questions about HVAC modelling
I am trying to model the HVAC system of the building that I'm studying for my thesis and am having some difficulties regarding which fields I should fill and which not. I have filled the fields up to group-airflow and I don't know what to do after that.
I read in the BigLadderSoftware site that Sizing:Zone, Sizing:System, and Sizing:Plant will be generated by the HVAC system so, I guess I don't have to fill anything in these fields?
Also, do I have to create nodes and branches? Or do I just fill the fields that are required for my HVAC system?
The HVAC system that exists in the building is a 2 pipe fan-coil so, so either choose the 4 pipe option or the ideal loads one.
Why don't you use a GUI as OpenStudio ? I find modeling a whole HVAC system in E+ really difficult, specially without strong knowledge of the software.
I don't think someone can really help you, as your question is too general. You should read HVAC documentation of E+ and try some simple examples to begin. Then you will probably have more specific questions.
