燃气三联供在建筑节能中的意义

CCHP system significance in building energy saving

能源是全球经济与社会发展的基本动力,随着人类社会发展的需求,以化石燃料为代表的能源变得越来越少,能源供应方式日益紧张.从能源消费结构中可以看出煤炭是我国主要的消费能源,伴随煤炭大量燃烧产生了粉尘、二氧化碳、二氧化硫、二氧化氮等大量污染物,严重污染大气环境.天然气作为一种清洁能源,因其效率高、污染少而越来越受到人们重视,并且燃气三联供系统具有投资省、损耗低、效率高、系统可靠性高等优点.通过实例论证分析,燃气冷热电三联供是建筑供热的最佳方式.

The energy like fossil fuel as the basic power for the advance of global economy and social development has decreased sharply,and ways for energy supply are still faced with an acute situation.However,coal still keeps the main position in energy consumption.With the appearance of pollution like powder,CO2,SO2,NO2,dust from the increasing burning of coal,air environment is destroyed.Natural gas,a kind of high-efficient and little-polluted energy,draws more attention.Meanwhile,CCHP system based on natural gas has such advantages as less investment,low loss,high efficiency and reliability.It is demonstrated that CCHP system is the best way for heat energy supply in buildings by the analysis of a living example in the paper.
