Custom Mechanical Systems and Critchfield Mechanical collaborate to create advanced in-row cooling technology installation for Brocade’s green data center in San Jose.  …

…   “The Brocade San Jose-based data center incorporates technology from CMS and CMI that provides a cutting-edge in-row cooling system with water-side economizer to minimize fan usage and maximize efficiency, saving half a megawatt of energy at full build-out. 

The custom cooling system from CMS and CMI has played a key role in the Brocade data center, featuring fan efficiencies superior to all other cooling options available on the market today.  

Brocade’s data center and its use of custom in-row cooling units, coupled with a highly efficient chilled water plant inclusive of a water-side economizer, provides a mechanical system with a power usage effectiveness (PUE) of less than 1.3. 

Data centers of this size typically have a PUE of greater than 1.5. 

To ensure a fully-customizable and flexible product, multiple iterations of the design were produced in order to meet Brocade’s specifications; 

CMS also worked with the construction team to design features that will simplify maintenance and improve reliability. 

These features include:

  • variable speed ECM motors, 
  • fan redundancy, and a 
  • low-cost maintenance design. ”   …

Data Center ASHRAE Prescriptive Cooling System Energy Efficiency

Posted in air-economizers, ambient-air-cooling, ashrae, cooling-system, data-center-efficiency-program, economizer, energy-efficiency, google, standards on April 13th, 2010 by FrankM – Comments Off

Google and its industry peers react to ASHRAE cooling standard for data centers. …

… “Unfortunately, the proposed ASHRAE standard is far too prescriptive. Instead of setting a required level of efficiency for the cooling system as a whole, the standard dictates which types of cooling methods must be used. For example, the standard requires data centers to use economizers — systems that use ambient air for cooling. In many cases, economizers are a great way to cool a data center (in fact, many of our companies’ data centers use them extensively), but simply requiring their use doesn’t guarantee an efficient system, and they may not be the best choice. Future cooling methods may achieve the same or better results without the use of economizers altogether. An efficiency standard should not prohibit such innovation. ” …
