Datacenter airflow management is a cost-effective way to ensure that your existing cooling system is as efficient and effective as possible. Benefits include increasing cooling capacity, lowering operating costs, increasing equipment reliability, and reducing bypass airflow. There are several key areas that facility managers must manage to optimize their cooling system and airflow in their critical facilities.
Air Filter Maintenance
One of the most important data center maintenance tasks is ensuring equipment runs at optimum efficiency with clean air filters. Industry best practices recommend changing data center air filters every quarter for best results.
Floor Grommets & Blanking Panels
Raised floor brush grommets and blanking panels are designed to decrease bypass airflow. Bypass airflow is any supply airflow delivered into the data center that is not consumed by the IT equipment. Floor grommets and blanking panels increase capacity, enable higher equipment density, and lower energy consumption.
Directional Airflow Panels & Grates
Directional airflow panels and grates direct the supply airflow at the server cabinets. By directing the airflow at the cabinet, servers capture more cooling and help decrease bypass airflow. Directional airflow panels can help reduce temperatures at the top of cabinets.
Dampers and Controls
Delivering the right amount of airflow to the right place is a key component of an energy-efficient data center. Automatic and manual floor dampers can be adjusted to match heat loads in the data center. Dampers significantly reduce bypass air and improve PUE.
Aisle containment can be categorized into cold and hot aisle configurations. The cold aisle confines the cold supply air so that it is only available to the equipment and cannot escape out the aisle ends or over the top of the aisle. Hot Aisle Containment focuses on isolating hot exhaust air on its return to the CRAC units or on its way out of the building. Aisle containment is the most efficient way of managing airflow in a data center.
