隧道废热回收研究现状

A survey of research in tunnel waste heat recovery

隧道在公共交通中的应用越来越广泛,山岭隧道、地铁隧道和海底隧道都是交通建设中必不可少的一部分.隧道中列车或机动车等运行会产生大量热量,相应设备以及车站内照明、人员等也会产热,大量废热堆积造成了隧道热环境恶化.近年来国内外研究人员先后提出了多种有关隧道废热回收的方法,使得隧道废热加以利用,既改善了隧道热环境,又使废热变为一种供热能源,达到节能减排,保护环境的效果.重点对目前相关研究现状进行总结,为今后研究提供参考.

Tunnels are becoming more and more widely used in public transportation.Mountain tunnels,subway tunnels and submarine tunnels are all indispensable parts of traffic construction.The operation of trains or motor vehicles in the tunnel tend to generate a lot of heat.And the corresponding equipment,lighting and personnel in the station also generate heat.The accumulation of waste heat will cause damage to the tunnel thermal environment.Researchers at home and abroad have proposed a variety of methods for tunnel waste heat recovery in recent years.Through the utilization of tunnel waste heat,such methods not only improve the tunnel thermal environment,but also turn waste heat into a kind of heating energy to achieve the effects of energy saving,emission reduction and environmental protection.This paper focuses on a survey of current research and provides reference for future research.
