山西某银行数据中心冷水机组选用对比分析

Comparative analysis of the chiller selection in a bank’s data center in Shanxi

根据银行数据中心全年不间断运行,显热量大,潜热量小的运行特点,结合焓湿图,介绍了蒸发冷凝式冷水机组和自然冷却风冷式冷水机组在数据中心机房的应用,并对二者运行费用、COP等进行了对比分析。得出结论:西北、华北地区数据中心建议采用蒸发冷却结合压缩机制冷的复合冷却式制冷方式。

Based on the bank data center’ s continuous operation throughout the year,the sensible heat is large,and the latentheat is small.Combined with the enthalpy-humidity diagram,the application of evaporative condensing chiller and natural coolingair-cooled chiller in the data center room is introduced.A comparative analysis of the two operating costs,COP,etc..It is conclu-ded that the northwest and north China data centers recommend a combined cooling method of evaporative cooling combined withcompressor cooling.
