This month, Fujitsu Laboratories Limited announced the development of cooling technology that employs waste heat generated by CPUs to produce chilled water that can be used to cool server rooms.
The Fujitsu technology can chill water from relatively low-temperature sources that have not been usable in the past. At 55°C, water produced from water-cooled type CPUs is of a relatively low temperature, which fluctuates depending on load. However, it is possible to continuously produce chilled water even from this waste water.
This technology offers the ability to use a CPU's waste heat to cool a datacenter, which had previously been impossible, and could save about 20% of the power used to air condition datacenters, which accounts for approximately 40% of all power used by datacenters. For a single server rack, which consumes up to 12,000 kWh per year, this is equivalent to the volume of CO2 cut by 360 cedar trees.
