This paper discusses data center scale performance characterization of hybrid liquid-air cooling solutions for a full 42U rack of servers. Using data collected in a production data center at Lawrence Berkeley Laboratories, we interpret the results with a simple three parameter model which allows characterization of the major factors affecting heat recovery efficiency of the system. The model is shown...
Our theoretical studies showed that absorption refrigeration (AR) system and organic Rankine cycle (ORC) are the most promising technology candidates in utilizing the waste heat dissipated by data centers. Since both candidates work with heat of temperatures not less than ∼65°C, this study is limited to water-cooled and hybrid two-phase cooled data centers. However, there exist challenges in the integration...
