Notes
  • cold aisel increased energy consumption,perimeter cooling or hot tile containment can be prefer where high density racks are not present.

    traditional cooling prefer provided direct air short cycling is not there or pex are not giving short cycling alarms

Cold Aisle Containment Overview

  1. 1. Cold Aisle Containment A Brief Overview for Data Centers
  2. 2. Air Mixing Lowers Delta-T • Cooling efficiency suffers • Capacity unnecessarily limited
  3. 3. Containment Stops Mixing • Cooling efficiency surges • Capacity expands

  5. 5. What is Containment? Placing isolation barriers at the front, back, and top of the aisles to eliminate cold air loss and to stop hot air from penetrating into the cold aisle. The reduction in air mixing increases the return air temperature to the CRAC units, raising the delta-T across them which results in more efficient cooling. The isolation also eliminates hot spots and makes the supply air temperature more uniform across the server inlets. This increases reliability while allowing the supply air set points to be safely increased.

  7. 7. Rigid Panels for Across Aisles
  8. 8. Compelling ROI • Payback typically less than a year • Immediately turn off CRAC units • Variable speed fans run slower • Reduce heat related failures • Eliminate unnecessary re-humidification • Increase CRAC set points • Increase chilled water set points • Increase the amount of economizer usage time • Extend the data center’s life
