InRow ACSC 100 in non-tbar data room

[BillP]

We have three ACSC 100 in row cooling units that cool 4 cabinets which have rear containment. It is within a data room with an existing AC unit that also cools the data room. Has any body used this scenario but without the option of a t-bar ceiling to vent and intake air? What solution did you use.

Our building has an attic space where it can get hotter than the recommended threshold of cooling the coils of the inrows. We were thinking of using the cool intake from the cold air the inrow and existing AC produces but aware of the negative air pressure it will produce. Another options was putting a chiller to cool the attic.

Any ideas please post.

Thanks,E
