使用空气保护系统已成为数据中心行业日益增长的趋势，也是数据中心优化的重要节能策略。冷通道封闭(CAC)是高密度热负荷应用中最有效的被动冷却解决方案之一。冷通道密封通过封闭冷通道，防止热空气再循环和冷空气旁路，在冷空气和热排气之间提供物理隔离。这种隔离为服务器提供了均匀的入口空气温度，从而进一步提高了数据中心的整体效率。本白皮书包括设置和不设置CAC的数据中心实验室的热测试数据。在两种不同的机房空调回风设定值条件下，对三种不同机柜热负荷条件下，在开放式热通道/冷通道(HA/CA)布置上实施CAC系统的热影响进行了量化。研究了CAC相对于标准HA/CA方案的优势。一个案例研究表明，与标准的HA/CA安排相比，使用CAC系统可节省22%的冷却能源。版权所有©2013，ASME
The use of air containment systems has been a growing trend in the data center industry and is an important energy saving strategy for data center optimization. Cold Aisle Containment (CAC) is one of the most effective passive cooling solutions for high density heat load applications. Cold Aisle Containment provides a physical separation between the cold air and the hot exhaust air by enclosing the cold aisle, preventing hot air recirculation and cold air bypass. This separation provides uniform inlet air temperatures to the servers, which can further contribute to overall data center efficiency.This paper includes the thermal test data for a data center lab with and without a CAC set up. The paper quantifies the thermal impact of implementing a CAC system over an open Hot Aisle/Cold Aisle (HA/CA) arrangement for three different cabinet heat load conditions at two different CRAC (Computer Room Air Conditioner) return air set point conditions. It studies the advantages of CAC over standard HA/CA arrangement. A case study has been presented showing a cooling energy savings of 22% with the use of a CAC system over a standard HA/CA arrangement.Copyright © 2013 by ASME
