Study on Rural Household Heating Demand and Envelope Insulation Schemes in Northeast China
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.
