In August, 2012 the Swedish construction giant Skanska together with the American IT company Inertech patented technology of energy saving cooling of server racks eOPTI-TRAX, Wall Street Journal reports.

As you know, issues of cooling in data centers are crucial, considering rapid growth of loading as well as growth of popularity of cloud services, high-performance computing and so forth.

According to tests, the new technology allows to cool air in data centers from 70 to 24 degrees.

The uniqueness of technology consists in coolant. When using it will be transformed from liquid state to gaseous and cools a rack due to heat exchange. It is possible to return it to liquid state already at a temperature of 30 degrees using chillers and the cooling equipment and to reuse as much as necessary long.

Thus, the technology allows to raise the time spent in the mode of free cooling of the server room to 83% a year without additional mechanical cooling. At the same time, traditional cooling systems in the same mode can stay no more than 24% a year.

At the same time, energy consumption of the solution counting on one 300 Watt server will be 0.3-0.5 Watts while traditional cooling systems consume up to 90 Watts on one server.

"The cold wall" as it is called by the senior vice president of Skanska company Jacob Karnemark, will be delivered in eHive or eComb options. eHive - autonomous a container which can be established in passes between racks or directly be mounted on a back cover of a rack. eComb can be placed in the existing DPCs or at construction of the new building as the main cooling system.

The similar solution on cooling of the server hardware provides IBM. IBM Heat eXchanger fastens to a back cover of a rack, replacing it thereby, and cools the server.

Skanska and Inertech patented the technology in department of the USA for patents and trademarks in the field of energy saving.
