It is not my call but thanks for the information. We will be seeking help from the experts to analysis the effectiveness of the mixing process
Thanks again for the help. Appreciate it.
Thanks for all the concerns regarding the safety issue of using such a system for fire suppression.
This is an interesting link I came across while trying to find out more about this form of system.

The 15% concentrate of oxygen is what I am concern about because I don’t think I can do a simple calculation to determine the conditions taking that into the account and I am not capable of solving complex mathematic problems as well. We are actually getting an expert to analysis the given...
Hi jistre
I believe that you are right to say that there is something wrong with the calculation. Could you please guide me to the right equation? To be honest, I am not very good in subjects relating to mixtures of gases and that is why I am having problems here.
Could anyone give me more...
Hi dcasto
I must confess that I am not too sure about the calculations process. Could you help me with it? If we are using a property relation between the states:
P1/T1 = P2/T2
3/(273+28) = 1/(273+X)
Nitrogen entering the room will be -173°C. Is this right?
I don’t have a clue to the mixing...
There will be oxygen sensors in the space to ensure that the oxygen level is maintain at a volume of 15%. No oxygen illness on human is reported at this concentration moreover the rooms are used for archives. Any damages to these precious collections are the last thing we want to see.
Thanks a...
There will be a leakage of 17l/s of air from the room. The nitrogen is used for fire suppression in the archive room. As this room condition is controlled between 16°C to 20ºC and RH between 45% to 60%.
I am wondering what will be the impact on the room condition when it enter the space. I...
I would like to know what will be the temperature and relative humidity of a room when compressed nitrogen (72CMH) at an absolute pressure of 3 bar, 28 deg & -50deg C dew point entering it at atmospheric pressure.
Any help would be greatly appreciated.
Can anyone please advice the impact when compressed nitrogen at an absolute pressure of 3 bar, -50deg C dew point entering a room (atmospheric pressure, 20 deg C 45% RH) at a volume flow rate of 72CMH.
Is this consider a polytropic expansion process?
Any help would be greatly appreciated.
