The HVAC-Diagram program is a simple utility that can be used to generate a svg file based on the bnd file generated by EnergyPlus. It is a stored in the primary EnergyPlus\PostProcessor folder upon installation.
It creates a series of diagrams for the layout of the HVAC system components. The SVG file can be viewed with a number of internet browser plug-ins such as produced by Adobe that can be downloaded at www.adobe.com/svg. To get help within the Adobe viewer, right click anywhere on the drawing.
Each diagram should be read from left to right, which is the direction of the flow of the fluid through the components.
The HVAC-Diagram program is automatically called when using EP-Launch but can also be included in other batch files. To view the drawing in EP-Launch, click on the drawing button. You can zoom in on this drawing and with the “copy” command, paste a zoomed in portion as a bitmap in your document.
