摘　　要：在碳中和背景下,村镇生物质与太阳能资源具有广阔的应用前景。以河北迁安地区某农宅为基础,建立三维模型,采用Trnsys对农宅能耗进行预测,通过实测数据对模型进行验证。分析不同供能方式的碳排放和经济性,结果表明:该农宅以天然气为燃料的供暖方式具有较高的CO_(2)减排潜力,CO_(2)排放量为2 019.75 kg/年,以生物质+标准煤的供暖方式具有较好的经济性,花费1 034.42元/年;当安装太阳能光伏发电系统时,采用生物质+空调的采暖方式具有较好的经济性,花费464.62元/年,且CO_(2)排放量为3 060.56 kg/年,仅次于天然气。因此,合理利用天然气、生物质和太阳能成为减轻供暖经济负担,降低CO_(2)排放的有效方法。To achieve carbon neutrality,biomass and solar power are of promising prospects in rural areas.A 3D model based on rural housings in Qian'an city,Hebei province is constructed.Energy consumption of these buildings is predicted by Trnsys,and the model is validated by measured data.Analyzing the carbon emissions and economy of different energy supply methods for the buildings,it is found that the heating mode with natural gas as fuel can reduce the carbon emissions to 2019.75 kg/a,and the heating mode integrating biomass and standard coal can bring the cost down to 1034.42 yuan/a.If PV power generation system is installed,the heating mode integrating biomass and air conditioning will reduce the cost to 464.62 yuan/a,and the carbon emissions to 3060.56 kg/a,which is only second to that emitted from the gas heater.Utilizing natural gas,biomass and solar energy reasonably is an effective technique for improving the economy of heating and reducing the CO_(2) emission.
