Re: [EnergyPlus_Support] Re: could anyone help checking my input file

I was out for several days.
I have uploaded the idf. But do not know where to find the link. It is in the file tag, with introduction "leebye to yuanlu li"
Thank you very much.

I think, I did ask you to post your IDF.  Have you done It?

Debugging EPlus is not difficult.  Simply follow the error messages and trace the problem systematically.

Node list and branch list, etc. are used to help you organize yourself and save you typing wrong names when using the IDFeditor to input to EDF..  When the content of an object is the same, you may use a nodelist and let the computer to do the expansion work.

If you have posted your IDF, please let me have the link.

A little bit. You mean use nodelist to reference more than one nodes?

I take it as that the inlet and outlet may correspond to more than one nodes each.. If so, in the nodelist in the node-branch management, you should fill in the names.

Thus, the outlet node of the AHU shall be the zone inlet node. The component inlet node depends on where the air is from. If it is from the return air of a zone, it shall be the zone return node. If it is from the outdoor air, it shall be listed in the outdoor air nodelist.

The input column does not contain any place to input "outlet node".It only contains "zone inlet node". That is, for unctrolled component, the atu inlet node is also the zone inlet node(that's true according to input output reference doc). But error comes like"the inlet node is "not connected to any zone". I cannot find any place to put the zone inlet and component outlet together.

Include all the componants and sub componants. concentrate just on air for the time being (later you can do the same for the water loops) and make sure to illustrate the nodes with their respective node names.
