Definition: KyotoCooling


A water-free datacenter cooling system from KyotoCooling (www.kyotocooling.com) that uses a rotating heat exchanger wheel that resides above the equipment floor. The rising hot air from the servers is absorbed in the wheel, which is cooled with outside air. The cooler air is sent back down to the servers.

Commonly used in combination with traditional air conditioning (DX compressors), which can be idle as much as 75% of the year depending on geographic location, KyotoCooling saves water and power. In addition, KyotoCooling datacenters can have equipment on cement floors rather than raised floors, allowing taller, heavier equipment racks to occupy the same footprint. See rack mounted and datacenter.



The KyotoCooling System
A massive, spinning corrugated aluminum wheel (the KyotoWheel) is cooled with outside air in one plenum while it absorbs the heat from the server racks in another.
