You probably need to use some of the archived eQUEST releases:
Download a <http://www.doe2.com/download/equest/eQUEST_v3-61b_Setup.exe>
complete eQUEST version 3.61b installation
Download <http://www.doe2.com/download/equest/eQUEST_3-55_Refrig-Add-On.exe>
the eQUEST version 3.55 refrigeration version add-on
<http://doe2.com/download/DOE-22/DOE22Vol2r-DictionaryRefrigeration.pdf>
Volume 2R: DOE-2.2 Language Dictionary: Refrigeration Version
These are made to work on refrigeration (i.e. cold rooms), and should avoid
the below 55°F issue

Hussein,
I had this problem in 1985 when we simulated an ice rink with DOE-2. This
was documented in the paper:
Haberl, J., Claridge, D. 1985. Retrofit Energy Studies of a Recreation
Center, ASHRAE Transactions-Research, Vol. 91, Pt. 2, pp.
1421 - 1433 (June).
We seemed to be able to estimate the answer by raising the "A" in the "U x A
x delta T" expression that relates to the conduction. A similar expression
could be used to account for the heat gain from the
infiltration/ventilation...

hello;
I am trying to simulate a walk in cooler in eQuest, but the zone entering
supply air temperature under coil capacity/control, cooling control and
reset is not allowing me to enter value below 55F. I need to set it up to 25
F. is there a way to overcome this problem.
thank you for your help
