 (separate compressors, evaporators, and condensers) while the standard version would have to be forced into modeling it and certain components might not even be able to do that.<o:p></o:p></span></p>

 pick TRNSYS instead just due to the flexibility to build in multiple unique components.  If your model is more of a standard refrigeration system, though, the refrigeration version of eQuest should be fine.  I’d recommend getting in touch with the James Hirsch

<p class="MsoNormal">Dear All,<br>
<br>
We are faced with an ice cream factory where all the production spaces and finished product warehouse spaces are cooled with ammonia absorption chillers. We are trying to understand if there is any need to use the eQuest Refrigeration version? What are the
 advantages of this over the standard eQuest releases? As far as I know, the standard version can also model absorption chillers. In which cases does it make sense to use the Refrigeration version? What are your recommendations on how to approach modeling this
 building?<br>
<br>
Thank you,<br>
