[Equest-users] Refrigeration Load in a refrigerated warehouse

[Kevin Campbell]

Hi,

First time poster here, my name is Kevin and I'm pretty new to eQuest and I have a few questions about a current model I'm working on.

I'm working on a refrigerated warehouse in eQuest Refrig 3-61, I've created a refrigeration system and assigned the refrigeration system as the Cool Source for Pkgd VVT system for each freezer zone.  When I run a simulation and view the output there is no energy attributed to "Refrigeration" it seems to all be put into "Space Cooling" is this normal or is there any way to separate the energy consumed by the refrigeration system for easier analysis?

Secondly, I get the following errors following a simulation while viewing the output files, and have tried a quite a few things to try to correct them and I'm not exactly sure of the cause but I cannot seem to find anything to fix them.
