Great Idea! I had proposed doing the same on this forum before, but I did not get much feedback. I have created a few of these (by hand) for my own use, however they would be EXTREMELY helpful for understanding how the HVAC in E+ works, and also for understanding how example files are set up. What program did you use to generate these diagrams?

Maybe the
present forum can help on making a database of HVAC diagrans. I teach E+ and I
am finding it very challenging to explain the modeling of HVAC systems in E+
that is why I try to draw a lot of diagrams (there are other issues as well
like naming nodes and branches etc in an consistent and self explanatory
manner).
I think
that if we can agree to some basic principles we can start building a database
that anyone can contribute.
I attach
two examples of such HVAC diagrams that I use in my lectures. I have several
others using the same logic. I will be happy to share them (actually I was
developing accompanying idfs of a three zone building for each of them but
after a while I did not have the time to update them).

Plus the EnergyPlus Development Team is a diverse set of
developers -- each of whom is responsible for their own documentation.
For better or worse, we don't have a technical editing team that massages (or
worse, tries to explain) the concepts. So, the developers do the diagrams
in the method they prefer or is easiest for them or is what they use when they
create technical papers for publication.

I believe that the diagrams in the manual were created over a number of years as new were implemented. Using a consistent style at this point in time means that someone would have to go back and re-do all the diagrams.

It's hard

suggested unless they are ..... born of water and spirit.
Is there
any historical explanation to that?

The diatrams are good, except that there are many parallel
lines, because the loops are placed side by side.
If you place the zone on top as the first page, followed by
system, heating/ cooling, condensing, etc. , the demand is always on top,
and supply at the bottom. The diagram would line up with the IDF and make
it a better debugging tool.
Node name and data can be included, 9on screen or on the
print out page) may be even as a separate layer, but displaied together.
Linking the set points with the actuaters and the design values.
Just some suggestions.

The new design builder HVAC diagrams (and design tools) are
excellent-see attached.. I recently purchased
a copy and took the training. The soon to be released version also has HVAC
templates for ASHRAE system types + more.. If anyone ever needs an IDF with
some specific systems I could produce one for them rather quickly..

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

If Open studio has got the bugs out I am sure many users would

Hi Rob,
I have installed OpenStudio
I tried to import one of e+ example files,
SolarCollectorFlatPlateWater.idf.
It looks like OpenStudio didn't recognize quite a few

Please
advise.

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.

[Bldg-sim] Tools to draw HVAC diagrams
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

Pavel, just Excel with formatted cells and arrows ? pretty unsophissticated, 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 itâ??s a â??primary ? seecondary pumping loopâ??.
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?
