<br>
We model a refrigerated warehouse using ESPr and TRNSYS. We did not try
Energy+.<br>
The main reason was to evaluate the effect of the thermal mass stored against
the incoming product that was warmer.<br>
when we compare our result to those of the refrigeration contractor there was a
big difference. Half of their calculated load<br>
And compare to actual energy consumption, it was close.<br>
<br>
So if you use energy+ be shure to include thermal mass.<br>

We had this problem before in the mid-80s simulating an ice rink at a <st1:place
w:st="on"><st1:PlaceName w:st="on">Rec</st1:PlaceName> <st1:PlaceType w:st="on">Center</st1:PlaceType></st1:place>.
This was published in an ASHRAE Transactions paper. We basically got around the
issue by fudging the "U x A x Delta-T"...in this case fiddling with
either the U or the A to adjust for the Delta-T. Results worked well against
metered data.<br>

Subject: [Bldg-sim] Walk-in Coolers/Freezers<br>
<br>
Hi all,<br>
<br>
Is it possible to use EnergyPlus to model a walk-in cooler or freezer? I
have tried but regardless of the temperature setpoint I choose for the freezer,
the modeled temperature does not want to drop below about 42 F.<br>
<br>
Also, has anyone made a model of a cooler that accurately estimates electricity
loads? I was able to model a cooler with a 45 F setpoint but I was way
under the electricity consumption estimates I found for coolers/freezers on the
web. I think my problem was the large amount of electrical usage for
non-compressor loads defrost cycle, evaporator fan, condenser fan, etc.<br>
