严寒地区农村住宅外墙节能优化研究

Study on energy-saving optimization of rural residential external walls in severe cold region

对大庆市杜蒙县杏树岗村的农宅外墙节能进行研究,发现农村住宅外墙大多采用无保温37黏土砖墙,采暖期的室内舒适度低,能耗高。在Ecotect中建立建筑模型,通过逐时温度曲线和逐月能耗模拟2个方面对农宅的外墙进行能耗分析,提出外墙保温层厚度设计最优值,得出大庆市农宅的外墙采用55 mm聚苯乙烯泡沫板作为外保温系统最为经济和节能,为寒地农宅室内热环境优化提供指导。

To study the investigation of the exterior wall of the farmhouse in Xingshugang Village,Dumeng County,Daqing City. It is found that most of the external walls of rural houses use no insulation 37 wall,which has low indoor comfort and high energy consumption during heating period. The building model was built in Ecotect,and the energy consumption of the external wall of the farmhouse was analyzed by the hourly temperature curve and the monthly energy consumption simulation. The optimal value of the thickness of the outer wall insulation layer was proposed,and the farmhouse in Daqing was obtained. The outer wall is made of 55 mm polystyrene foam board as the most economical and energy-saving external thermal insulation system,which provides guidance for the optimization of indoor thermal environment in cold farms.
