<p class=MsoNormal>
I am modeling a laboratory with several large walk-in coolers and freezers. I
am interested to hear anyone’s opinion on this modeling strategy as I
have found very little guidance in the literature.<o:p></o:p></p>
<p class=MsoNormal style='text-indent:.5in'>I am not using the refrigeration
version of eQUEST. I am using the built-in refrigeration tab. I understand,
from the help file, that this model assumes a refrigerated case rather than a
walk-in. A schedule was assigned for the cover with a value of 0 for all hours
to represent a closed case. A dummy value is entered in the Zone load to enable
refrigeration (I believe that this value is negated by the cover) and the case
temperature is specified.<o:p></o:p></p>
<p class=MsoNormal>
I then made sure that all the walls in each of the refrigerated zones is
adiabatic including the external walls (effectively by creating a construction
with a zero U-val). I am now specifying the actual heat rejection of the
equipment (from the designer) in the plenum (where it is actually being
rejected). The heat will be divided between each plenum space weighted by area
to simulate an open return plenum.<o:p></o:p></p>
