Emerson Network Power announced global availability of air- and fluid-side economization solutions for data centers on Thursday.

The announcement included a chiller plant, a system for dynamic control of compressor and pump operation guided by outside air temperature and an air economization system for pumping outside air inside the data center.

“When a data center is located where weather conditions are favorable, economization can be a viable strategy for reducing energy use … and cutting costs,” Emerson VP of Marketing Fred Stack said in a statement. “However, because business continuance is the ultimate goal of any data center, it is important to weigh the benefits of different types of economizers against their associated costs and risks.”

Emerson emphasized the importance of evaluating climate conditions in the area where a data center is located to find out whether deployment of economization solutions will yield energy savings that will justify the investment.

The chiller plant Emerson announced this week uses outside temperature to cool water in its chilled-water loop before it is delivered to multiple cooling units, reducing the time of chiller operation. Hours of economization depend on several factors, including wet bulb temperature and the temperatures of supply and return water.

If used with Liebert CW, the precision cooling system pictured above, the new chiller plant may lead to substantial energy savings, according to Emerson

The compressor and pump control system, named Liebert Glycool System works like a typical glycol-cooled DX system as long as outside air temperature is not cold enough to cool fluid in the heat rejection loop. Once outside air temperature drops to an adequate level, the system switches off or reduces operation of the compressor and the pump, using outside air instead.

Finally, the Liebert air economizer pumps outside air into the data center, resulting in operation-time reduction for compressors within the cooling unit and the chiller plant. Optional sensors can be installed along with the economizer to control an outside air damper in accordance with conditions.
