Re: [EnergyPlus_Support] WaterToAir Heat Pump for Cold Stores

["Michael J. Witte" <mjwitte@xxxxxxxx>]

Air is taken from the hall, chilled, then blown into the cold store?  Where 
does the air leaving the cold store go?  Where does the hall get its makeup 
air?  Is all of the system flow from the hall, or just a fraction of it?  
Perhaps you can configure this as a return plenum?
