某电信机房热管节能改造能效分析

Energy Efficiency Analysis of Heat Pipe Energy Saving Transformation in a Telecommunication Room

目前单元式水冷多联热管被广泛应用于数据中心的冷却。但是系统运行受室外温度的影响较大,需要在不同的模式之间进行切换。传统的热力学分析方法计算粗糙,只能间接的反映系统的实际运行过程。应用有限时间热力学分析方法。真实再现了系统的实际运行过程。针对长沙某电信机房传统的风冷精密空调改造前后的全年能效进行了建模和计算。结果表明全年节能约300万kW·h。

At present,the unit water-cooled multi connected heat pipe is widely used in data center cooling.However,the operation of the system is greatly affected by the outdoor temperature,so it needs to switch between different modes.The traditional thermodynamic analysis method is rough and can only indirectly reflect the actual operation process of the system.In this paper,the finite time thermodynamic analysis method is used.The real operation process of the system is reproduced.This paper models and calculates the annual energy efficiency of the traditional air-cooled precision air conditioner in a telecommunication room in Changsha.The results show that the annual energy saving is about 2 million kWh.
