AisleLok Aisle Containment – The easy way to improve Row Airflow Management
AisleLok Aisle Containment is a unique aisle containment system that can be self-installed straight out-of-the-box and start delivering improvements in Row airflow management and efficiency.
We conclude Airflow Management Awareness Month and our recent series of blog articles by looking at the improvements that can be made at the rack Row level. Our first blog article, ‘Improving Raised Floor Airflow Management Helps Optimise Data Centre Cooling’, looked at the changes that can be made to improve airflow management at the Raised Floor level. Next, we looked at the improvements that could be made at Rack level in our blog ‘Improve Data Centre Rack Airflow to Help Optimise Cooling’.
As with Raised Floor and Rack levels, the aim of good airflow management at Row level is to prevent the mixing of air streams between the cold air cooling the IT equipment and the hot exhaust air expelled by it. The best way to do this is through the installation of an aisle containment system.
Aisle Containment is an established and effective means of improving airflow management within Data Centres and IT rooms. It involves segregating the hot and cold aisles and in doing so it greatly improves the management of both conditioned air delivery and hot air return paths. Aisle containment solutions reduce the risk of hot and cold air mixing, bypass airflow, and air re-circulation – all of which contributes to cooling optimisation & potential energy efficiency gains at the CRAC unit.
There are two types of aisle containment systems:
- Cold Aisle Containment – Where the cold aisle is enclosed via a roof and end of aisle doors. It is then flooded with conditioned air that cools the equipment. As the aisle is enclosed the hot exhaust air is unable to wrap over the top or around the sides of the cabinets and mix with the cold air.
- Hot Aisle Containment – This is where the hot aisle is contained and hot exhaust air is directed into the ceiling plenum where it returns to the CRAC units cooling the Data Centre.
Both methods have their Pros and Cons, but essentially deliver similar results. Aisle Containment systems normally need to be designed and expertly installed which can be a costly process, particularly where the need to add additional racks to rows is a requirement.
