[EnergyPlus_Support] Schematics for Example Files

[Eddie Corwin <ecorwin@xxxxxxxxxxxxxxxxxxx>]

Great schematic! I always do the same when I am modeling with E+.  Has anyone ever compiled schematics for all of the example files?  It would be EXTREMELY helpful in understanding how the systems are set up if schematics were included with the example files.  If there is no one on the E+ team that can do this, it could be crowed-sourced and done in a very short time.  Does anyone else think that HVAC system schematics for the example files would save a lot of time?

Dear Greg,

 

Itâ??s very possible!  Iâ??m completing a model which uses the Heat Exchanger in the configuration shown on the schematic, and it is working well.  My particular model does not use 100% OA, but I think all youâ??ll need to do is set up the Controller:OutdoorA ir object to have a minimum fraction which is always = 1 (something like what Iâ??ve shown below).

 

p.s., The example files are helpful, but you have to wade through all of the node names to figure out whatâ??s connected to what.  I always make a schematic to help keep them straight.

It is contradictory to insist that future generations respect the natural environment when our educational systems and laws do not help them to respect themselves.  (Let's do both.)
