Granular Airflow Control for Constant IT Load
The Multi-zone Opposed Blade Damper when installed beneath a DirectAire directional airflow grate significantly reduces bypass air and enables the airflow delivery to be balanced based on the specific load in a 14U section of the rack. The damper allows data center operators to individually adjust airflow to three zones within the rack (top, middle and bottom) without removing the DirectAire panel, ensuring fast and accurate balancing to the fixed IT load.
When the Multi-zone Opposed Blade Damper is fully open, it restricts airflow by just 10 percent, which represents a dramatic airflow improvement over traditional manual slide dampers. The damper’s drop-in design allows for easy installation by decoupling the damper from the panel. This means that standard, undampered directional airflow panels can be ordered as needed, with separate opposed blade dampers purchased so they can be added whenever and wherever necessary.
The Multi-zone opposed blade damper can also be used when blanking panels cannot, to shut off or dampen airflow to different sections of the rack where large portions are left empty. This is especially important in data centers where co-location operators are unable to install blanking panels in their customers’ racks, or IT managers are unable to keep blanking panels installed in their own racks. Zoned dampening can allow IT managers to optimize the airflow quantity far more accurately.
Another advantage to the data center operator is an increase in potential available critical power. The reduction in airflow volume as a result of using DirectAire’s directional airflow and closing off airflow to unused sections of racks reduces the energy usage for cooling at the CRAC unit level. This can allow an increased efficiency of the datacenter proportional to the deployment of the technology.
