Your diagrams are very good and well illustrated. However, it does not have a topological view that shows relationship of the whole HVAC system.
The attached diagram is modified from the EPlus lecture notes.
Which tool is used to produce the diagram is not important. I think, the diagram provide more information and in a complete system view. It can be enhanced to show all the IDF objects, when enlarged in sections.
The diagram can be enlarged in sections and preserving the relative demand and supply relationship. More additional special equipment may be added in the same demand/supply relationship.
I have also seen one diagram with the demand on top and supply at the bottom, in three long pages with heating and cooling plants side by side. If you then add list, connection, equipment side by side onthe diagram, it make the IDF tracing very easy. Set point managers can be added to show the set values, and control actuators.
The arrow between the branches should mean "use the outlet node name as the next inlet node name".
The round dots should be replaced with an arrow.
The zone and OA mixer box is actually, a mixer and splitter with by-pass branch inside them.
Infiltration and ventilation in a zone are additional branches feeding the mixer from OD air, and exhaust the zone air via the internal splitter to OD.
I do not like the diagrams in the New OpenStudio. It only show part of a system. The connection number in the new format are also not for human interface. Building geometry input is from a third party.

Here is a Visio-made diagram
What do I miss? Is it satisfactory for a report/manual/paper?
First round, about 3 hours, about 10 iterations.
Just one click to get all formatting you need.
Very fast learning track.
Very useful Format painter and very flexible connectors
Less frustrating experience comparing with Word which I used before.
Next time, I hope, it's gonna take 20-30 min

Would you say that Open studio is finally "ready" for real world projects? I have been a fan, and have made effort to use it for years but just never found it to work very well (looks great tho)If Open studio has got the bugs out I am sure many users would jump on board- so is it ready?Best regards-

I would humbly submit OpenStudio (openstudio.nrel.gov) as a tool for diagramming these systems. The OpenStudio application has a visual HVAC system design tab in the interface that has been engineered to allow idiots like me to create ASHRAE standard system types, and customize from there as needed. While the graphics may not be super sexy, they tell the story. Further, after you've dragged and dropped your way to a functional and valid HVAC system description, you not only have a series of graphics that illustrate it, you also have underlying code describing this system in OpenStudio-speak, as well as EnergyPlus-speak, ready for simulation.

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?.M.A.Sc<http://M.A.Sc>. Candidate, Department of Architectural Science
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?
