数据中心采用冷却塔供冷系统形式的初探与展望

The Application and Prospect of Cooling Tower System in Data Center

面临能源与环境的双重压力,在数据中心运用新的节能技术来减少能耗,提高制冷效率,同时将环境污染减少到最低程度,已成为数据中心制冷行业发展的首要任务。在借鉴各类文献及实际测试的基础上,介绍了2种数据中心常用的冷却塔供冷系统。延伸的又提出3种有望实现的冷却塔供冷系统在数据中心的应用方案。着重介绍了这5种冷却塔供冷系统的原理、特点和运行模式,提出该系统的设计难点,并总结出几个提高空调系统能效比的设计要点。为该类空调系统在数据中心的应用提供参考依据。

Facing the pressure of energy and environment, the application of new energy-saving technologies in data center to reduce energy consumption, improve the refrigeration efficiency, and reduce the environment pollution to the lowest degree at the same time, has become the primary task of data center refrigeration industry. In this paper, based on the literature and the actual test, two cooling tower systems commonly used in the data center are introduced. The extension of the proposed three kinds of cooling tower systems are expected to achieve the application of the data center. Therefore, this paper focuses on the principle, characteristics and operation modes of the five cooling tower systems, puts forward the design difficulties of the system, and summarizes several design points to improve the energy efficiency ratio of the air conditioning system. Hoping to provide reference for the application of the air conditioning system in the data center.
