数据中心正在成为一个大型工业部门，消耗全球电力供应的 3%，同时排放温室气体总量的 2%，其中多达一半最终以热量的形式浪费掉。因此，研究的重点是收集这种废热能的技术。提出了一个框架及其随附的决策支持工具，该工具确定废热源和散热器的兼容性、火用平衡和时间可用性，以及可用换热器技术的经济和环境效益，以提出简化和优化的热回收策略。所包含的案例研究证明了数据中心能源效率的显着提高以及热回收投资回收时间的缩短。
Data Centres are emerging as a large industrial sector, consuming three percent of the global electricity supply while contributing for two percent of total greenhouse gas emissions, with as much as half ultimately wasted as heat. Consequently, research has focused on technologies for harvesting this waste heat energy. A framework and its accompanying decision support tool is presented which identifies the compatibility of waste heat source(s) and sink(s), exergy balance and temporal availability, along with economic and environmental benefits of available heat exchanger technologies to propose a streamlined and optimised heat recovery strategy. Substantial improvement in data centre energy efficiency together with reduction in payback time for heat recovery has been demonstrated in the included case study.
