Typically, refrigeration systems are modeled with a combination of Refrigeration:Case and Refrigeration:CompressorRack objects. This is how walk-in freezer/cooler and refrigerated display case systems are modeled in the Hospital, RestaurantFastFood, RestaurantSitDown, SchoolPrimary, and SchoolSecondary Commercial Prototype Building Models. There are other ways of modeling refrigeration systems, including Refrigeration:AirChiller and ZoneHVAC:RefrigerationChillerSet (see ExampleFiles), but I don't believe any of these objects support absorption chillers.

Depending on the zone load and the setpoint temperature that your cold storage room needs to maintain, it may be possible to serve the room with an air system that utilizes chilled water from an absorption chiller (similar to a CRAH), but this would probably be classified as a special air handling system rather than a refrigeration system.

That what I concluded also from my research, so I'm trying to get it done with a simple air handling unit. But I'm not sure how I can model the products inside the room, is InernalMass object sufficient for this purpose?
