Definition: KyotoCooling

A water-free cooling system for data centers from KyotoCooling that uses a rotating heat exchanger wheel that resides above the equipment floor. Commonly used in combination with traditional air conditioning, which can be idle as much as 75% of the year depending on geographic location, KyotoCooling saves water and power. In addition, KyotoCooling data centers can have equipment on cement floors rather than raised floors, allowing heavier equipment to occupy the same footprint.

Thus far, KyotoCooling has not been used for AI data centers because moving air is not sufficient for the heat dissipated by huge numbers of GPU servers. See rack mounted, data center cooling and underwater data center.

The KyotoCooling System

The rising hot air from the servers is absorbed in the massive spinning honeycomb-like KyotoWheel in the server plenum, which is cooled in the outside-air plenum. The cooler air is sent down to the servers.
