数据机房双冷源空调系统设计与分析
Design and analysis of double cold source air conditioning system for a data center
摘要：
介绍了数据中心常用的3种空调系统形式——常规冷水空调系统、单冷源+板式换热器空调系统和双冷源+板式换热器空调系统，结合北京某数据中心机房，通过损失和效率分析得出，中温双冷源和板式换热器空调系统相对于传统系统有较低的能耗和较高的效率。

Abstract：
Presents three air conditioning systems commonly used in data centers — conventional chilled water air conditioning system, single cold source plus plant heat exchanger air conditioning system and double cold sources plus plant heat exchanger air conditioning system. With a data center in Beijing as example, by analysing the exergy loss and exergy efficiency, concludes that the middle temperature double cold sources plus plant heat exchanger air conditioning system has lower energy consumption and higher energy efficiency than that of the conventional system.
