Moving the air conditioner closer to the equipment rack ensures a more precise delivery of inlet air and a more immediate capture of exhaust air. Close-coupled cooling aims to bring heat transfer closest to its source: the equipment rack. Though their solutions vary in terms of configuration and capacity, their approach is the same. A potential remedy for these problems is close-coupled cooling, where the once distant air conditioner is moved closer to the actual compute load.Ĭlose-coupled cooling is a recent entry into the data center lexicon, and many manufacturers apply the term to describe their latest generation cooling products.

With high performance, denser computing, the traditional layout of perimeter CRACs, fans, and perforated floor tiles struggles to deliver the required volume of cool air, to maintain a uniform server inlet temperature, and to expel exhaust air from the room. Close-Coupled Cooling Solutions for Server Racks, Computer Rooms & Data CentersĬlose-Coupled Cooling is an ideal solution for high-density configurations, eliminating hot spots while improving energy efficiency.
