Emerson Network Power (NYSE: EMR), a provider of critical infrastructure for information and communications technology systems, announced that the California Energy Commission (CEC) has approved for use in California data centers the company's Liebert DSE thermal management system, with the Liebert EconoPhase Pumped Refrigerant Economizer.
The Liebert DSE system represents a breakthrough technology that uses no water and saves up to 50 percent of thermal energy, says Emerson, through its patented design and advanced Liebert iCOM controls. According to a press release, the CEC has approved the Liebert DSE system with Liebert EconoPhase as a prescriptive economization option, as part of Title 24 of the the CEC’s 2103 Building Energy Efficiency Standards For Residential and Non Residential Buildings, meeting the code’s requirements for energy efficiency and its prescriptive requirements for economizers.
Emerson notes tha the Liebert DSE system eliminates the need for any water in the heat rejection process and associated chemical water treatment, and it eliminates the risk of exposure to harmful waterbound bacteria. In addition, Emerson claims its modeling for the CEC compliance program demonstrated an 8 to 10 percent reduction in the data center Time Dependent Valuation measure, compared to the water economizer prescriptive option.
The Liebert DSE system design also reduces or eliminates several of the power components associated with water economizers. In actual usage, the entire Liebert DSE system has demonstrated thermal system energy savings of up to 50 percent over older legacy systems.
“The Liebert DSE system is a great environmental steward," asserts John Peter Valiulis, vice president North America marketing, thermal management, Emerson Network Power. "When used in a typical mid-sized data center of one megawatt load, the Liebert DSE is significantly more efficient than current cooling systems, and eliminates the use of around four million gallons of water each year. If deployed broadly in California data centers, the Liebert DSE with EconoPhase could save hundreds of million gallons of water every year.”
