【 摘 要 】

Exergy model and the least exergy loss principle are introduced to analyze the exergy loss distribution in heat transfer and air/water flow process, for a combined server/cabinet cooling network. Based on the optimized case suggested by the exergy model, a multi-stage water cooling scheme is designed, with two-stage heat exchanger in server cabinet, and double-chiller in the water loop. Both thermal and energy performance of such cooling infrastructure has been tested in a data center in China, with the measured performance in good agreement with the designed values, and the exergy loss model has been validated.
