摘　　要：东北地区清洁取暖改造工作正处于关键时期,围护结构节能改造是保障该项工作顺利实施的重要环节,但现有关于东北地区农房围护结构节能改造技术节能率及经济性的综合性研究较为缺乏,难以指导技术方案选取。通过实地调研获取东北地区典型户型、围护结构特点和采暖需求特征,利用DeST建模计算多种围护结构节能改造技术的节能率,并综合考虑节能效果和经济效益确定适宜当地的围护结构节能改造方案。结果表明,当地农房主要为三间半式和两间半式户型,采暖房间数主要为2-3间,且70%的农户主要在1间有炕的卧室活动,呈现部分时间全部采暖空间为主的采暖特征。简易阳光房+30mm北墙EPS保温的围护结构节能改造方案,节能率达到17.4%,总改造费用最低,仅为2354元,是兼顾节能与经济的优选方案。研究结果可为东北地区农房围护结构节能改造和清洁取暖工作提供理论和数据支撑。Clean heating project in Northeast China is at a critical stage,and envelope insulation implementation is a key part to the success of this project.Existing research on the energy-saving efficiency and economy of rural house envelope insulation technologies in Northeast China is relatively lacking,which makes it difficult to guide the technical schemes of rural house envelope insulation in this region.Therefore,based on the field survey and DeST modeling methods,this study obtained the characteristics of typical house thermal characteristics,heating demands,and the energy saving efficiency of a variety of envelope insulation technologies in Northeast China,and combined the energy-saving effect and economy to determine the appropriate envelope insulation scheme.The results showed that rural houses in Northeast China were mainly three-and-a-half-room and two-and-a-half-room house types,and most had 2-3 heating rooms and 70%of the households were mainly in one bedroom,which presented a part-time-part-space heating characteristic.Simple sunroom and north wall insulation with 30mm of EPS can save 17.4%energy for heating,and the total renovation cost was 2354 RMB,which was the suitable solution based on economy and energy saving effect.This study can provide theoretical and data support for the implementation and popularization of rural house envelope insulation in Northern China.
