Air cleaning system for the data center - Environmental - Environmental Management
The challenge for data center managers is to maintain or improve availability in increasingly dense computing environments while reducing costs and increasing efficiency. Even though data centers are strategic business assets that continue to grow in importance, data center managers are under pressure to optimize operational expenses and reduce energy consumption without risking downtime.
Previous generations of data center HVAC systems had to operate at full capacity all the time regardless of actual load demands. And Uninterruptible Power Supply (UPS) systems operated most efficiently at full load although full-load operation is the exception rather than norm. A lack of flexibility in the power and cooling systems led to inherent energy inefficiency which has created a large opportunity for HVAC energy savings which can account for 35 percent of data center energy costs.
In any building using pre and post filtration of MERV 8 and 13 or even higher, Dynamic can reduce mid-life static pressure by more than 1 inch and design static by more than 1.75 inches.
Lower static pressure corresponds directly to lower brake horsepower. Brake horsepower drives fan energy and so on. With Dynamic Air Cleaners, and using the prescriptive option under section 6.5.3 of ASHRAE 90.1, engineers can reduce energy and provide every customer with a payback worth investing in.
Dynamic Air Cleaners integrate perfectly with newer data center cooling technologies that utilize variable speed fan drives to adapt to changes and deliver high efficiency at reduced loads, which can result in fan energy savings of 50 percent or more.
Using an example of a 34,000 cfm air handler and a $.16 blended utility rate, using a Dynamic V8 Air Cleaning System instead of 85% cartridge filters can save over $8,000/year in fan energy costs. Just from the reduction in static pressure in this model, design brake horsepower is reduced 14.3 bhp.
