冀东地区既有农居节能改造的全寿命周期碳排放分析
Life cycle carbon emission analysis of existing rural residential energy-saving transformation in eastern Hebei
摘要：
建立了碳排放减排率模型，并对所提出的节能改造方案进行了计算与验证。结果表明：农居围护结构改造后的碳排放较改造前可降低52.85%~86.72%；外墙、屋顶的材料生产碳排放量比门窗的材料生产碳排放量大。在农居围护结构改造的基础上分析了3种热源改造方案的投资回收期，其结果为节能型燃煤炉的投资回收期最短，其次分别为空气源热泵和燃气壁挂炉。
Abstract：
In this paper, the carbon emission reduction rate model is established, and the proposed energy-saving transformation scheme is calculated and verified. The results show that the carbon emission of the rural residential building envelope after reconstruction can be reduced by 52.85% to 86.72% compared with that before reconstruction, and the carbon emission of material production of exterior wall and roof is greater than that of door and window. On the basis of the reconstruction of the building envelope of the rural residence, the payback periods of three heat source reconstruction schemes are analysed. The result is that the payback period of the energy-saving coal fired furnace is the shortest, followed by the air-source heat pump and the gas wall mounted furnace.
