Energy Saving In Data Centers

摘要

Data centers are by far the largest energy users in commercial building space. The biggest potential energy savings can be achieved by utilizing lower outdoor temperatures to cool the data center, thereby reducing mechanical refrigeration power consumption. Various winter free cooling systems are available for large data centers. The most common is the use of a traditional water cooled chiller, which utilizes an outdoor evaporative cooling tower and an indoor plate & frame heat exchanger. When the tower water is cool enough to provide partial or full cooling capacity it is routed through the heat exchanger, which then cools the chilled water supply to the air handlers, CRAC units or rack coolers.
