数据中心园区供冷供热方案浅析
Analysis of cooling and heating solution for data center campuses
摘要：
对于同时有供冷供热需求的数据中心园区，有些数据中心会采用冷热源独立设置的方式，例如供冷采用间接蒸发冷却空调系统，供热采用市政热水或燃气锅炉。也有些数据中心会使用冷凝热回收技术，采用热泵机组夏季供冷，冬季同时供冷供热。本文针对冷热都有需求的数据中心园区进行系统分析，通过数据对比，探讨不同方案的可行性和应用场景。
Abstract：
For data center campuses that require both cooling and heating, some data centers use independent cold and heat sources. For example, indirect evaporative cooling air conditioning systems are used for cooling, and municipal hot water or gas-fired boilers are used for heating. Some data centers use condensate heat recovery technology, using heat pump units for cooling in summer, and cooling and heating in winter. This paper analyses data center campuses that require both cooling and heating, and explores the feasibility and application scenarios of different solutions through data comparison.
