Inrack Calcs with a Grid Overhead system
Inrack Calcs with a Grid Overhead system
(OP)
So calculating a InRack System with the Ceiling having an existing grid system. The overhead system will need to be modified to make the calcs work. The contractor only wants to modify the portion of the grid directly over the racks. Is that acceptable?
When you run a calc like this do you calculate the most hydraulically remote part of the grid to balance with the inrack system or do you only calculate the part of the grid directly over and within 15' of the inrack system?
Thanks in advance for your help.

Since you need to modify the ceiling anyway, did you look at ceiling only ESFR/CMSA options, to avoid the in-racks? You would still need a draft curtain to separate QR from SR heads at the ceiling, but it may be a wash money wise, and you avoid the dreaded in-racks that most operators don't want.
