从数据中心回收废热仍然是一项困难的任务。对于液冷数据中心来说，水温太低，因此在经济上不可能安装全面的热回收系统。特罗姆瑟大学（UIT）与IT制造商合作，进行了详细的研究，以调查从其当前数据中心获取废热的技术和经济可行性。单机架服务器已转换为液体冷却（仅限CPU）。测试机架的进水温度满足ASHRAE W2-W5液体冷却等级。在所调查的所有进水温度下，关键IT设备的温度保持在规范范围内，同时产生高达147.2华氏度（64摄氏度）的机架排气温度。根据目前的能源成本，并假设1兆瓦数据中心50%的废热被重新利用，每年有可能节省超过37.5万欧元。 随着UiT正在建设一个新的2 MW数据中心，更大的热量回收潜力可以极大地将数据中心废热的再利用扩展到更广泛的校园。引用:2016年冬季会议，佛罗里达州奥兰多，会议论文

Recapture of the waste heat from data centers remains a difficulty undertaking. For liquid-cooled data centers, the temperature of thewater has been too low to make it economically feasible to put full-blown heat recovery systems in place. The University of Tromso (UiT), incollaboration with an IT manufacturer, has undertaken a detailed study to investigate the technical and economic feasibility of capturing thewaste heat from its current data center. A single rack of servers has been converted to liquid-cooling (CPUs only). The rack was testedusing inlet water temperatures that satisfy ASHRAE W2-W5 liquid-cooling classes. Under all inlet water temperatures investigated,the key IT device temperatures remained well within specification, while producing rack exhaust water temperatures as high as 147.2degrees F (64 degrees C). Using the current UiT cost of energy, and assuming that 50% of the waste heat from a 1 MW data center is reused,there is the potential to save over 375,000 Euros annually. As UiT is building out a new 2 MW data center, the potential forgreater heat recapture can greatly expand the re-use of the data center waste heat to the broader campus.
