Greetings,
I am aware of the energyplus example files, the input/output reference, and engineering reference, and i have spent a while with all of the above.
I'm still not able to figure out what is required to model an HVAC system in energyplus, or how to properly model VAV controls so that the volume of airflow changes to meet the load in each zone. There are terminal HVAC objects, fans, airloop objects, supply loops, demand loops, branches, branchlists, controllers, nodes, schedules, and plenty more. How do they all fit together?
Can someone explain in a concise response, what energyplus objects are required for a VAV system, and what the role of each object is? I've read the documentation on most all of the objects in the VAV system example files, but there are just too many, and I can't keep it straight. Perhaps a comprehensive, brief summary exists somewhere that I haven't looked?
