The data center space is one of the most quickly evolving spaces, in terms of cooling system design, when compared to the rest of the HVAC market. Many engineered solutions to improve data center cooling efficiency and operation come to market every quarter, and many are rapidly accepted into new data center construction due to the benefits they provide. But the fast pace of data center construction means many of these solutions have come and gone.
However, one solution that remains is the simple idea of containing the cold and/or hot air paths in the space, separating them, and increasing site efficiency while providing a more predictable operating environment. Often, this solution is deployed before companies gain a full understanding of the ramifications these changes may have on the operating space. This article explores a recently discovered issue that can occur when using hot and cold aisle containment — server leakage induced by positive differential pressure.
