Hi Team,
Seeking your advice regarding vertical grills associated with a drawn wall inside the main layout. Some how the cooling is trapped in between the main walls and drawn wall "corridor" and does not go inside the data hall. Cooling properties for the vertical grills are all same which I modelled.
Any suggestion on how to make the cooling reach the data hall?
By the way I am using ITA ver 952.
Thanks,
Romeo

Hello. I have a couple of follow-up questions regarding your cooling configuration. What type of cooling units are you using in your room (from the screenshot)? Are these downflow devices where the air is pushed into the floor and then up through floor tiles into the room, or are these more like inrows where the air is pulled through the rear of the cooling unit and then out the front supplying the room directly?
Vertical grills must be balanced when deployed. See my above example of a simple room I created to mimic your room. Like your screenshot I have vertical grills on both the external and internal walls. I set their height to be 48" from the floor so they are in the middle of the wall because my cooling unit in my case is an inrow so the air is flowing straight through the hallway and into the room.
The grills are paired with the exact cooling unit airflow coming into the room as well as exiting the room. So if my inrow can supply 1000 cfm, then one pair of grills has 1000 cfm coming into the room, the other pair 1000 cfm exiting the room.
The cooling unit genome used also matters.. If you used a downflow like genome then the air is being pushed into the floor and you'll need grills under the floor to allow the airflow and floor tiles in the DC room to allow the air to floor from underfloor into the room.
