What are economizer systems and how do they improve energy efficiency?
This is the year that discussions around using outside air economization will be heard at many seminars. The introduction of Liebert’s DSE, as well as ASHRAE’s proposal to increase the server air inlet temperatures, will certainly allow considerable energy cost savings to those early adopters. Don Beaty, DLB Associates, recently conducted a US Government seminar on Data Centers speaking to how efficient we can become utilizing outside air as an economization strategy, as well as (dare I say it) primary means of cooling a Data Center. ASHRAE has recently released a study on areas of the United States where outside air, properly filtered and metered for gaseous and particulate contamination, can be considered as your primary source of cooling. Does your outside environment play a role in this decision? Absolutely. A thorough site assessment with a knowledgeable company is well worth the cost. We all need to ask ourselves why Facebook, Microsoft and others are choosing locations conducive to utilizing outside air.
