Cold Aisle Containment
IT equipment uses an enormous amount of energy daily to maintain an acceptable level of temperature. To help save energy, airflow containment systems are specially designed to separate cold supply from hot equipment exhaust air, which improves the cooling capabilities of data centres tremendously.
The cold aisle containment system encloses the cold aisle with ceiling panels above the aisle and with the doors at either end of the aisle. By containing the cold aisle, the hot and cold air streams are fully separated. Cold air will be able to flow from the raised perforated flooring into the aisle to be contained and delivered to the IT equipment air inlets, providing focused cooling.
Benefits
- Cooling systems can be set to a higher supply temperature and still supply the load with safe operating temperatures.
- Hot spots are eliminated.
- More energy-efficient as cooling compressors need not work as hard to diffuse heat.
- More efficient use of cabinet space as the need for traditional cooling equipment (i.e. large fans) are eliminated.
Prerequisites Prior To Installing A Cold Aisle Containment System
For the cold aisle containment system to be the most effective, Data Clean recommends evaluating the following considerations before installation:
1. Fire protection measures
Fire suppression and protection in data centres are crucial. When planning an airflow containment system, it is best to consult local fire authorities to make sure that safety codes and standards are being followed.
2. IT equipment layout
Assess any ergonomic challenges and amount of layout customization that is needed for the cold air containment system to operate optimally.
3. Expandability
The airflow containment system needs to accommodate the growth of the data centre. The containment system should have structures and components that are modular in design that can be easily relocated and expanded upon if necessary.
4. Equipment and personnel safety
Consider the placement of workers and equipment so that they are kept at a reasonable temperature that does not violate OSHA regulations and guidelines.
