RE: [EnergyPlus_Support] Re: SVG Flow Chart and Nodes

There is a list in the I.O Ref. Manual, to guide you on what are the fields or nodes that can be autosized.

If you are using HVACtemplate models in IDF and try to change the fields in the expIDF, the changed number may be ignored, as the next simulation of the IDF will have a different or original expIDF again.

If you are changing the number using a text editor or IDFeditor, you may have changed some other objects or the order of a branch.

For example, if you deleted a branch object and insert a new object with your changed field, the order in the file is changed. IDFeditor can only append and not insert. This is one possible way to generate connection errors.

There are other possibilities, such as an extra comma in the object.

When you first intriduce autosize in your IDF, you may be asked for a sizing object or to do sizing run.

I currently have a system where if I run it and have the CFM rate of the fan entered (lets say 5,000 CFM) it runs fine. However, when I try to autosize it, I get a bunch of Node Connection errors.

Is there an obvious cause of this?

But the order of these listing may not be the same as those in the SVG diagram as there are coordinates associated with these captions to draw them. The .bnd listing follows your IDF ordering. Dr. Li
