[BLDG-SIM] eQUEST: Bypass damper for Heat Recovery

DOE-2.2, and thus eQUEST, does not currently have models of CO2 sensors 
and controls but does model many types or heat recovery; look in the
DOE-2.2 Dictionary (Volume 2) on page 344-358 (PDF page 346-360) for the
details of keywords that are used to define the Energy Recover Ventilator (ERV)
capabilities.  Links to the six volumes of DOE-2.2 documentation for eQUEST
are found below the program download links (for the standard and refrigeration
system version of eQUEST - currently version 3.51 pre-release) at the website

   http://DOE2.com/eQUEST/ 

(Direct link to DOE-2.2 command and keyword dictionary in PDF format is

We have a project underway to adds some forms of CO2 sensors and
controls into DOE-2.2; those features may not be available until early
next year.  Until that time you would need to use a scheduled minimum
OA damper position to approximate the CO2 controls.

> Hi All,
> I am trying to modeling a system in eQUEST with an
> outdside air heat recovery. The unit has a built in
> bypass dampers on the return air to the energy wheel
> and the outside air.The outside air will be reduced by
> use of a CO2 monitor and the bypass dampers on the
> energy recovery wheel, that allows the return air to
> go directly to the coil section.
> 1) What is the method of installing a bypass damper in
> to the heat recovery in equest.
> 2) Is there a method of adding a CO2 meter which would
> regulate the outside to do in directly to the coil?
> 
> Thanks,
> Gerald
