Sample with a cold aisle depth of 1000mm

A cold aisle containment (CAC) system with a depth of 1000mm can be custom-engineered to enclose the cold supply air, ensuring efficient cooling and preventing hot air recirculation.

Overview

Cold aisle containment systems are designed to isolate cold supply air from hot exhaust air, directing cooled air directly to IT equipment intakes. This improves energy efficiency, reduces hot spots, and ensures servers operate within manufacturer-recommended temperature ranges. A 1000mm aisle depth is feasible and can be accommodated with custom CAC solutions, particularly in raised floor environments where underfloor plenums supply cold air.

Design Considerations

Aisle Width and Depth: While standard cold aisle widths often range from 1. 2m to 1. 8m, a depth of 1000mm (1m) is achievable with bespoke containment panels and doors.

The system should ensure that the cold air is fully enclosed along the aisle length to prevent bypass and mixing with hot air. Doors and Panels: CAC systems use sliding or hinged doors at aisle ends and roof panels above racks. For a 1000mm depth, single or double doors can be installed depending on aisle length and accessibility requirements.

Materials: Robust aluminum frames and polycarbonate panels are commonly used, providing durability and visibility while maintaining airflow containment. Integration with Cooling Units: The system should align with CRAH or CRAC units, capturing cold air from the underfloor plenum and directing it efficiently to server intakes.

Benefits

Energy Efficiency: Containment reduces the mixing of hot and cold air, allowing higher supply temperatures and lower energy consumption for cooling units. Temperature Uniformity: Cold aisle containment ensures a consistent intake temperature across all racks, minimizing hot spots and improving server reliability. Custom Fit: Systems can be tailored to specific aisle dimensions, including non-standard depths like 1000mm, ensuring optimal use of available space.

Implementation Tips

Ensure continuous runs without gaps between racks to maintain containment integrity. Use blanking panels and ceiling lids to prevent air leakage and maintain uniform airflow. Consider modular designs for flexibility in future reconfigurations or expansions.

By designing a CAC system specifically for a 1000mm deep aisle, data centers can achieve efficient cooling, energy savings, and reliable operation while accommodating space constraints and equipment layout.
