Economizer Fundamentals: Smart Approaches to Energy-Efficient Free-Cooling for Data Centers is an important reference piece. It explains what Data Center professionals need to know about utilizing outdoor air as a tool to optimize energy savings and climate control within the data center facility. The promise of economizer technology has drawn interest not only for environmental reasons but cost savings as well. However, there are geographical considerations and differences between systems.
This graph rich whitepaper compares the two types of economizers - fluid and air. The pros and cons of each one are explained in detail and how they can be utilized in places as diverse as Atlanta and Chicago. Considerations range from capital expenditure costs, best operating hours, duct work, estimating annual energy savings and safely bringing in outside air.
Special consideration must be given to the data center climate control system because sensitive electronics should only be subject to systems that are proven. However, with a potential of 50% energy cost savings this technology cannot be overlooked and deserves a serious review from the IT strategist.
