Emerson’s Data Center Cooling Technology Receives Patent

by | Jan 23, 2013

Emerson Network Power has received a US patent for its Liebert XD cooling technology that the company says can reduce a data center’s air conditioning energy consumption up to 30 percent when utilized as supplemental cooling and up to 70 percent when deployed as the primary cooling.

Implementing the Liebert XD solution requires 15-50 percent less chiller plant capacity, as well as less diesel generator and switch gear capacity, resulting in a potential energy savings of 40-50 percent for data center energy consumption, according to the company.

Emerson Network Power says its pumped refrigerant-based cooling technology used in the Liebert XD family of high heat density cooling solutions was the first rack- and row-based cooling solution to address high density at the rack level.

The Liebert XD family includes the Liebert XDV rack-mount, Liebert XDO ceiling-mount, Liebert XDH row-based and Liebert XDR rear door cooling modules. Originally designed to address hot spots or zones within the data center, the Liebert XD cooling modules provide cooling directly at the source of the heat without overcooling the whole data center.

The Liebert XD cooling technology can meet the needs of current 10, 20 and 30kW racks, and has the ability to support densities of 60kW or higher in the future, according to Emerson Network Power’s Steve Madara, vice president, global cooling. The flexible configuration of the Liebert XD system modules also allows scalability for future growth, and the ability to add redundant units for maximum reliability in the most mission-critical applications.

Additionally, the company says the Liebert XD approach improves floor space utilization compared to an installation using only floor-mounted cooling units. Because of the variety of cooling module sizes and placement, installing more Liebert XD capacity typically uses little or no additional floor area.

A fall 2012 survey by Emerson Network Power found data center energy costs and equipment efficiency are the top-of-mind issues for data center managers.

Earlier this week, the company introduced a team dedicated to serving the needs of massive data centers.
