含高热密度机柜的IT机房空调的节能措施

如今设有高热密度机柜的IT机房越来越多,传统机房空调设计中存在着使这种机房空调能耗增加的误区,即单纯追求机房内的环境温度,而忽略了如何有效地带走每台高热密度机柜的散热量这一核心问题。本文针对此问题,总结如下4个简单易行的节能措施:当单个服务器容量超过5kW时,可采用冷气流或热气流通道封闭;当单个服务器容量超过8kW时,可采用行级制冷或机柜级制冷;当高热密度机柜和普通机柜并存时,应均匀分布高热密度机柜;合理布局机房空调。

Energy conservation measures of air-conditioner for IT computer room with high heat density cabinets

Nowadays, high heat density cabinets are used more and more in IT computer room. There are many misunderstandings in air-conditioner design for traditional com- puter rooms that result in the growth of their energy consumption. Traditional design is simply pursuing temperature in computer room while neglecting how to effectively release heat from each high density cabinet. In order to solve the problem,the following four sim- ple solution measures are summarized： taking use of cold or hot aisle containment when single server capacity is over 5 kW, using row level refrigeration or cabinet level refrigeration when single server capacity is over 8 kW, evenly distributing high heat density cabinets when there are both high heat density cabinets and common cabinets, making rational distribution of air-conditioners for computer room.
