[October 21, 2009] Emerson Network Power: Emerson Network Power Digital Technologies Improve Energy Efficiency in Data Centers Tweet Marlow, Oct 21, 2009 (M2 PRESSWIRE via COMTEX) -- Emerson Network Power, a business of Emerson (NYSE: EMR) and the global leader in enabling Business-Critical Continuity, is the acknowledged provider of data center environmental solutions, characterized by the Liebert HPM precision air conditioning system. The Liebert HPM uses rugged refrigeration components that are designed to operate 24 hours a day, every day of the year, providing the precise temperature and humidity control required by sensitive electronic computer equipment. Nevertheless, Emerson Network Power offers optional additional features, utilizing the latest digital technology that improves operating efficiency. Consequently, the Liebert HPM Digital provides even greater energy efficiency, made possible in several different ways. The compressor is a key component but is a major consumer of energy within the air conditioning system if it is necessary to power on and off as the level of the cooling capacity varies. The Liebert HPM Digital, through innovative Digital Scroll technology, provides precise thermal management, without involving powering on and off, allowing continuous modification of the compression cycle and enabling capacity and load to be closely matched at all times. The resulting increased energy efficiency is further enhanced by two important thermodynamic advantages. The operation of the digital technology allows higher evaporating temperatures, leading to higher sensible cooling capacity, together with lower condensing temperatures, which result in reduced compressor power consumption. The Liebert HPM Digital has as a standard an electronic expansion valve (EEV) which allows the compressor to work with the lowest condensing temperature possible. The EEV ensures control of superheating throughout the entire length of the evaporator, provides immediate response to changes in environmental conditions and accurately controls the refrigerant flow. These qualities ensure that the compressor will never be flooded, enabling tolerance to lower condensing temperatures during winter time. Power input can be reduced further if the Liebert HPM Digital is equipped with an optional electronically commutated (EC) fan, which adapts the air volume to the cooling requirement. The EC fan also significantly lessens noise and heat emissions and its infinitely variable speed control extends the working life of moving parts, reducing maintenance costs and making a significant contribution towards overall savings in lifetime costs. The innovative technology utilized in the Liebert HPM Digital has the effect of improving the energy performance of an already energy efficient product. Taken together, it may be possible to reduce energy consumption by up to 50 percent, depending on the particular architectural and environmental characteristics of the installation.
