  1. Which option is better, hot aisle or cold aisle containment?

  2. Numerous data centres are experimenting with new or creative cost-cutting strategies in an effort to maintain their customer base. Keeping the data centre cold so that the equipment runs at its best efficiency is another significant power consumer. And as you are all aware, paying the electricity bill for air conditioning might leave your pocketbook feeling somewhat thin. Due to this, most data centres switched many years ago to containment structures that divide the cool airflow from the hot airflow brought on by equipment exhaust. Server racks and other IT equipment in a data centre may be arranged in a hot or cold aisle containment configuration. By managing airflow, cold or hot aisle containment aims to increase cooling efficiency, resulting in reduced cooling costs and improved energy consumption.

  3. The arrangement of server racks in alternating rows with cold air intakes on one side and hot air exhausts on the other is known as a cold or hot aisle containment design. The rows made up of rack fronts are referred to as cold aisles. Cold aisles face the direction of the output ducting for the air conditioner. Hot aisles, meanwhile, face the direction of the return ducts for the air conditioner. Cold and hot aisles are kept separate from one another by containment devices. To avoid the mixing of hot and cold air, this is done. Initial containment systems were Plexiglas coverings or vinyl plastic sheets used to physically divide hot and cold aisles. To further aid prevent the mixing of cold and hot air, companies now offer plenums and other alternatives that integrate containment with variable fan drives (VFDs).

  4. Is It Better to Contain The Hot Aisle or The Cold Aisle? Remember that improving the intake air temperatures for IT equipment and creating an environment where adjustments may be made to lower operating costs and boost cooling capacity are the same objectives of hot and cold aisle containment. That, however, doesn't actually address the query. This brings us to the specifics. The containment of cold aisles consists of doors at each end as well as a canopy or barrier covering the cold aisle. The same doors on either end of the hot aisle serve as hot aisle containment, and some kind of ducting connects the hot aisle to the AC return vents. For the purposes of this discussion, let's assume that the design of our hypothetical data centre allows for the choice of either hot aisle or cool aisle containment. Due to efficiency and something known as ride-through advantages, hot aisle may be the superior choice in this situation. However, because our fictitious data centre is flawless, it might not be the best for everyone. Choose the best solution for your need. Thank You !
