数据中心余热利用现状及在建筑供暖中的应用

碳中和背景下，将数据中心余热资源作为建筑供暖的热源，是降低建筑供暖碳排放的一种途径。为了系统掌握数据中心余热在建筑供暖中的技术应用现状，对近年来数据中心余热利用相关政策及标准进行了梳理，对影响数据中心余热利用的可行性因素展开了分析，整理了中外数据中心余热在建筑供暖中的应用案例。分析发现，政策与技术标准是数据中心余热回收利用的有力推动力；数据中心余热回收量受冷却技术、热量散发位置等多种因素影响，可以结合数据中心实际情况，综合选取余热回收位置；国外数据中心余热在建筑供暖中的应用较多，国内需要更多的实践和积累。

Development Support Status of Data Center Waste Heat Utilization and its Application in Building Heating

Under the background of carbon neutralization, taking the waste heat resource of data center as the heat source of building heating is a way to reduce the carbon emission of building heating. In order to systematically grasp the technical application status of data center waste heat in building heating, the policies and standards related to waste heat utilization of data center in recent years were combed, the feasibility factors affecting the utilization of waste heat in data center were analyzed and the application cases of data center waste heat in building heating at home and abroad were sorted out. It is found that policies and technical standards are a powerful driving force for the recovery and utilization of waste heat in data centers; The waste heat recovery capacity of the data center is affected by many factors such as cooling technology and heat emission location. The waste heat recovery location can be comprehensively selected in combination with the actual situation of the data center; Foreign data center waste heat is widely used in building heating, and more practice and accumulation are needed in China.
