摘要
在能源危机与“双碳”背景下,农村建筑节能减排的压力与日俱增。目前,北方农居建筑采暖方式通常为燃煤锅炉,能源效率低、环境污染严重,探索一种舒适、健康、绿色的农村低能耗建筑新能源采暖系统,已成为亟须解决的现实问题。研究基于绿色低碳理念,以北方地区农村居住建筑供暖系统为研究对象,在全面了解北方地区采暖现状的基础上,从全生命周期的视角,对比分析燃煤、电加热、燃气等多种采暖方式节能潜力及经济性,有重要的经济、节能、环保意义。研究结果表明:原农居建筑结构优化后,可明显减少约40%的污染物排放;环境负荷最大的是电采暖方式,SO_(2)、NO_(X)、CO_(2)排放量分别是燃气壁挂炉对应排放量的200倍、30倍和5倍。哈尔滨市采暖能耗和经济成本最高,环境负荷为4.04。
Against the background of the energy crisis and"Double Carbon",the pressure on energy saving and emission reduction in rural building is increasing day by day.At present,the heating method for rural building in the north is usually coal-fired boilers,which have low energy efficiency and serious environmental pollution.Exploring a comfortable,healthy and green new energy heating system for rural low-energy building has become a practical problem that needs to be solved urgently.Based on the concept of green and low carbon,this research takes the heating system of rural residential building in the northern region as the research object.On the basis of a comprehensive understanding of the heating status in the northern region,this research compares and analyzes various heating methods such as coal-fired heating,electric heating,and gas heating from a full-life-cycle perspective.Analyzing their energy-saving potential and economic feasibility is of great economic,energy-saving,and environmental significance.The research results show that after the optimization of the original rural building structure,pollutant emission are significantly reduced by about 40%;the largest environmental load is electric heating,and the emission of SO_(2),NO_(x),and CO_(2) are 200 times,30 times and 5 times the corresponding emission of gas wall-mounted boilers respectively.Harbin City has the highest heating energy consumption and economic costs,with an environmental load of 4.04.
