[dsg-eic_dirc] Fresh air intake installed in EEL 108 subroom

[Tyler Lemon]

Hi,

Yesterday, the work to install a fresh air intake in the EIC DIRC QA area in EEL 108 was completed.

The vent is located on the right wall if you are standing in the doorway. Photos from the inside and outside of the room are attached. For reference, the external dimensions of the grate are 16.5" x 16.5" and the diameter of the thru-hole in the wall is 4".

I've turned on the AC unit and will check on it before the end of the day. If all seems okay, I'll let it keep running over the long weekend to mainly confirm that it will hold any condensation it generates inside the AC unit (or at worst, the condensation is able to be contained inside the drain pan).

The next step for the air intake is to design a cover for the grate that will block external light while still allowing proper airflow. George already has a preliminary design for this cover, so it should go smoothly (hopefully...).
