带自然冷源的风冷冷水机组应用于数据中心的节能潜力分析

Energy- saving Potential of Air- cooled Water Chillers with Natural Cold Source in Data Center

数据中心的能耗正逐年上升,如何降低能耗已成为数据中心关注的焦点。以某地实际工程中带自然冷源的风冷冷水机组为例,比较使用常规制冷机组与带自然冷源的风冷冷水机组两种条件下的能耗。分析了在我国华北、西北及东北地区使用免费冷能的节能率及节电费,对全国范围内可使用免费冷能的气候条件进行了可行性探讨。

The energy consumption of data center has increased year by year, so how to reduce it has become the focus. This paper compared the energy consumption between the conventional refrigeration unit and the air-coaled water chillers with natural cold source that based on the practical engineering. Then the energy saving rate and electricity charge of using free cooling energy in north, northwest and northeast regions of China are analyzed, as well as the feasibility of free cooling energy for various weather conditions.
