[Equest-users] Walk-in Refrigeration in eQuest 3.64 DOE-2.2-47h2

[Christopher Rogers]

I am not sure if you have had the help you needed on this, but there is an eQUEST 3.61 Refrigeration version available for download at DOE2.com. This version is fully capable to model walk-in coolers, freezers, and refrigerated cases (ie: grocery store applications). Energy is reported for the standard end-uses for HVAC and lighting, with the addition of "Refrig Display" (compressors, cases, etc) and "Heat Reject" (condensers).

Subject: [Equest-users] Walk-in Refrigeration in eQuest 3.64 DOE-2.2-47h2

  Good morning eQuest users,

Has anyone successfully used the walk-in refrigeration feature under the 
Air-Side Refrigeration Tab?  I am modeling a small retail building with 
a walk-in cooler and freezer, both of which I have set up as PSZ 
systems.  Under the Refrigeration Tab, I selected Separate as the 
Refrigeration Circuit Type with appropriate capacities and EERs.  
Providing the Walk-in Box with a load, location (compressor group 
assignment), and a schedule, results in no change in energy consumption 
for the model.  Providing a Zone Load for Display Refrigeration under 
the Zone Refrigeration Tab results in an appropriate increase in the 
Refrig Display end-use.

I found the Walk-in Box key words in the DOE-2.2 dictionary, but 
virtually no other mention of the Walk-in Box feature in the 
documentation.  Perhaps I have missed something.  Any advice would be 
greatly appreciated.

Thanks,
Vern
