The temperature in the computer room is being increased from 18°C/64°F to 27°C/81°F. What is the impact, if any, on the amount of gas required to…

With Halocarbon fire suppression systems, as the temperature increases, the amount of gas required

for effective suppression decreases. This is because Halocarbon agents are stored as a liquid and

discharge as a gas, expanding more at higher temperatures. As a result, less agent is needed at

higher room temperatures to achieve the desired concentration for fire suppression.

Detailed Explanation:

Halocarbons rely on specific volumetric concentrations to suppress fires. Higher temperatures cause

the agent to expand more rapidly, effectively filling the protected area with less agent needed to

reach the required concentration. This is in contrast to some other gases, where temperature

changes might not have the same effect on discharge quantities.

EPI Data Center Specialist Reference:

EPI data center training on fire suppression indicates that understanding the physical properties of

agents like Halocarbons is key for correct system sizing. As the temperature rises, the gas expands

more readily, thus requiring adjustments in the amount needed for effective coverage.
