What is Data Center Economizer?
Data center economizers are technologies commonly used in data centers to cool data center infrastructure. These primarily consist of two things – Air economizer methodologies and water economizer methodologies. Air-side methodologies use direct, fresh air blown into the data center with hot air extracted and discharged back outdoors, or they may use an air-to-air heat exchanger. Cooler outdoor air is used to partially or fully cool the interior data center air. The other, water methodology removes heat from the chilled water loop by a heat exchange process with outdoor air. When the cooling tower water loop is cooler than the return chilled water, it is used to partially or fully cool the chilled water.
