回收数据中心冷凝热用于北方地区供暖的效果分析
Performance analysis of condensing heat recovery from data centers for heating in northern China
摘要：
一方面，我国北方地区冬季的供暖能耗巨大，另一方面，近年来数据中心的数量和规模快速增长，其空调系统的冷凝热通常直接排放到大气中。采用逐时稳态模型，分析了热虹吸/蒸气压缩复合空调系统回收数据中心排热用于我国北方地区典型城市居住建筑的供暖效果。结果表明：每回收1 000 m2常规数据中心的冷凝热可为哈尔滨1.3万m2、北京1.6万m2的居住建筑供暖；如果能够提供10%的辅助供暖热量，其供暖面积将增大60%以上，且系统的投资回收期短于2 a。
Abstract：
The heating energy consumption in northern China is huge, meanwhile, with the rapid development of data centers, a large amount of exhausted heat from data centers is usually emitted directly into the ambient. Based on a steadystate hourly energy model, adopts the thermal siphon / vapor compression integrated air conditioning system, and analyses the heating effect in typical cities in northern China. The results show that the condensing heat recovery from a common data center of 1 000 square meters could provide heating for a residential building of 13 000 square meters in Harbin or 16 000 square meters in Beijing. Furthermore, the heating area would increase by more than 60% and the payback period be no longer than two years if 10% of the total amount of heating could be provided with assisted heating system.
