Abstract

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.
