LNG接收站与数据中心冷热源耦合利用技术及经济性分析

Technical and Economic Analysis of Coupled Utilization of Data Centers and LNG Cold Energy-Cold and Heat Sources

在LNG接收站中,LNG气化过程释放大量冷能,通常采用海水作为热源气化LNG,不仅浪费了LNG冷能资源,也对周边海洋环境造成了冷污染。近年来,互联网的蓬勃发展对数据计算、储存、传输等需求呈爆发式增长,数据中心的建设越来越多,但数据中心运行需要消耗大量电力,为保证数据中心正常稳定运行,需要消耗大量的冷量来消除其散热。本文重点分析了数据中心与LNG冷能冷热源耦合利用的技术经济性,分析结果表明:节能减排效果明显、技术经济可行,可为相关行业提供一定的参考。

In LNG terminals,a lot of cold energy is released during LNG vaporizing.Seawater is usually used as a heat source for LNG vaporizing,which not only wastes LNG cold energy resources,but also causes cold pollution to the surrounding marine environment.In recent years,with the booming development of the internet comes an explosive growth in the demand for data computing,storage and transmission,etc.More and more internet data centers have been constructed,the operation of which entails a lot of electricity consumption.To ensure normal and stable operation of internet data centers,a lot of cold energy needs to be consumed for heat dissipation.This paper focuses on analysis of the technology and economy of the coupled utilization of internet data centers and LNG cold energy-cold and heat sources.The analysis results show that it bears obvious energy saving and emission reduction effects and is feasible in both technical and economic terms,which makes it able to provide certain reference for related industries.
