Re: [Bldg-sim] Tools to draw HVAC diagrams

If you are familiar with AutoCAD for drawing schematics then you will be able to use Draftsight from Dassault systems. It's free.

Sorry for cross-posting,

Does anyone use MS Visio for sketching HVAC diagrams? 

Is it a good alternative to Ms Word, which is somehow tolerable for simple diagrams, but gets really out of hands for bigger diagrams?

The shapes, which are included in Visio, are they helpful, meaningful, give professional look?

Somebody is using Excel (might be lacking flexibility when topology is unknown).

Somebody is using Inkscape.
Any other thoughts

Thank you,

Pavel Dybskiy

No “tool” Pavel, just Excel with formatted cells and arrows – pretty unsophisticated, but easier (I think) than learning Inkscape.  I know of others using Inkscape, however, and it looks like a very capable tool.

Hi Jim,

What tool do you use to draw your diagram?

 

Dear List,

I'm wondering if you can share your thoughts on your favorite tool to draft efficiently such diagrams.

Is there anything better than pencil and paper?

 

Thanks,

 

Paul

Dear Forum,

The schematic I have attached is a common boiler plant piping configuration in my experience, using an individual constant speed pump for each boiler, plus a variable speed distribution pump.

Officially it’s a “primary – secondary pumping loop”.

I cannot make the primary pumps shut off when the corresponding boiler is inactive.  Has anyone successfully modeled this configuration?  Do you know of an example file with this configuration?

Thanks in advance.

 

Making me think….

Why is it?  We routinely use miracles of creativity and technology that 50-100 years ago would be considered impossible or black magic … and also assume that whole segments of society are incapable of helping themselves  or acting intelligently.  Is it a self-fulfilling expectation?
