数据中心冷冻水空调系统多级制冷方案研究

摘要

Data center chilled water supply and return water temperature differential flow control has become an ideal model to reduce the transmission of chilled water, but this model will reduce the end heat transfer efficiency of the room air conditioning.This article presented a high power cabinet in a closed thermal channel scene using cooling water tower.This pre cooling mode can reduce the air temperature differences, improve the thermal efficiency of airconditioning terminal fan coil.%数据中心冷冻水供回水高温差变流量控制已经成为一种降低冷冻水输送的理想模式,但这种模式会降低机房空调末端换热效率.对此,文章中提出了一种高功率机柜在密闭热通道场景采用冷却塔自来水的方式,在密闭热通道中采用预冷方式能够降低回风温差,提升空调末端风机盘管换热效率.
