摘　　要：高热密度机柜的不断应用使得数据中心能耗剧增,高效节能的数据中心冷却技术变得越发重要,提高自然冷源在数据中心冷却系统中的利用率已成为降低数据中心空调系统能耗的重要手段之一。概述了数据中心冷却系统的能耗及发展现状,对旧存数据中心冷却系统存在的自然冷源利用率低和气流组织分配不均等问题进行了总结。简述了蒸发冷却技术在数据中心的应用情况,同时,从除湿技术、装置和材料等方面出发,综述了固体除湿系统的研究进展,对固体除湿系统实际运行性能、节能效果、适用性和可行性方面的研究做出了展望;针对蒸发冷却技术不同地区气候适用性的问题,提出并设计了一种固定床除湿器,其可与蒸发冷却系统耦合应用于数据中心的空调系统,以期降低数据中心冷却系统的能耗。Energy consumption of data centers increases dramatically with continuous application of high thermal density cabinets. Energy-efficient cooling technology plays a more important role in data centers. A significant way to reduce the energy consumption of data center cooling systems is to improve the utilization rate of natural cooling sources. In this regard, the paper outlines the energy consumption and development status of data center cooling systems. Problems such as low utilization of natural cooling sources and uneven distribution of airflow organization in the old data center cooling systems are summarized. Application of evaporative cooling technology in data center is stated, and research progress of solid dehumidification system is reviewed from the aspects of dehumidification technology, devices and materials. Research outlook on the actual operation performance, energy saving effect, applicability and feasibility of solid dehumidification system is also conducted. To reduce the energy consumption of data centers, a solid dehumidification fixed bed focusing on climate adaptability of evaporative cooling is proposed and designed, which can form a cooling system by coupling with evaporative cooling.
