New projects are one of our specialties.
Cold Aisle Containment Solutions are most commonly used for retrofits applications. The installation of an aisle roof usually eliminates the need to modify fire suppression and fits below existing cable trays and power buss bars. Colocation data centers often prefer Cold Aisle containment because it is easy to reconfigure.
Cold Aisle Containment (CAC) deploys aisle door and, in some designs, a roof systems to contain cold supply air for IT equipment. CAC prevents mixing of cold supply air with hot exhaust air and also prevents “short-cycling” a phenomena in which hot exhaust air is pulled back into the intake of IT equipment.
CAC also ensures stable and uniform delivery of cold air all the way to the top of each rack. This supports total utilization of RU space in every rack. CAC is also easier to install as it does not interfere with overhead cable trays.
Hot Aisle Containment Solutions focus on isolating hot exhaust air and close coupling it to the return of the computer room air conditioner (CRAC). This method of containment is clearly the trend for most new enterprise data center builds. Hot Aisle Containment (HAC) works well with “air side economizer” systems which use “outside air” to cool the supply side of the room. Isolating and containing the hot air also makes the general access area of the data center more comfortable for humans.
AFCO Systems fabricates and designs all of our containment solutions at our factories. Many “containment companies” use third party fabricators adding cost and lead time to your order.
Hot Aisle Containment deploys a physical barrier that guides hot exhaust air from IT equipment back to the return of the cooling system. In some design applications, the hot exhaust air can be expelled from the building or even re-routed to warm other areas for creature comfort. HAC can increase cooling efficiency by 30% or more. Cost savings can be achieved in many ways, including; adjustments in temperature and humidity set points, lower fan speeds and higher chilled water temperatures.
