Hi all,
For designing a total flooding high pressure carbon dioxide system in a 3,500
cubic feet computer room with electrical equipment and cable runs, I have
specified my room as "Dry electrical hazard" with flooding factor of 0.083
lb/cubic.feet and 50% design concentration according to NFPA-12.
My questions are as below:
1)- Is a computer room fire a deep seated fire?
2)- NFPA 12 states that "For deep-seated fires, the design concentration
shall be achieved within 7 minutes, but the rate shall be not less than that
required to develop a concentration of 30 percent in 2 minutes." Is it a
problem if the total discharge time would be only 1 minute for this case?
Many thanks for your help in advance.
Reza
