[Equest-users] auxilliary heat and desiccant wheel

[Alan Crittendon]

Thanks that is very helpful.  However, I think I have something
fundamentally wrong with the HVAC.  I have two airside system types.  One is
the packaged hvac heat pump and one is the unit I am going to use as the
fresh air erv.  I have them both assigned to the same shell component under
the first screen shown below.

 



 

When I try to do what you say below and modify the systems under detail
mode, I see this.

 



 

  Where am I supposed to modify the heat recovery?  Under each zone?

Hi Alan!

 

1.       "auxilliary strip heat:" Not totally sure what specifically you're
talking about (vocabulary disconnect probably), but I think you'll find what
you're looking for under the "supplemental heat/defrost tab" in detailed
mode.

2.       Look in the same place first. alternatively you may be able to
specify dual fuel as a pre-heat option

3.       Easiest approach, for projects large and small, generally is to:

a.       Go to the airside system(s) served by the OA unit, 

b.      Enable/define energy recovery inputs (including wheel properties),
and 

c.       Proportion out the delivered flow rates and fan/process energies of
your OA unit between the served systems

How do I factory in the auxilliary strip heat or use a dual fuel heat option
for packaged heat pumps?  Also how do I put in a desiccant wheel for an
outside air unit?
