摘要:

针对严寒地区村镇住宅屋顶能耗现状和保温技术特点,并基于对目前严寒地区村镇住宅屋顶保温和节能目标的要求,提出了符合当代村镇住宅特征的屋顶上层与下层分设保温层的复合保温构造模式;阐述了该模式的设计理念及模式内涵,建立了该模式下的吊顶封闭空间热平衡数学模型,给出了不同保温层选材的厚度参考值.该模式的提出为我国严寒地区村镇住宅屋顶保温和节能设计提供了新的设计对策.

Abstract:

According to the energy consumption status and roof insulation technical characteristics of rural housing in severe cold region,a double-layer composite roof insulation model for roof insulation and energysaving is proposed,which adapts to the contemporary rural housing roof features.The design of the model is described;a mathematical model of heat balance of the enclosed space under the ceiling of the pattern is set up,and the thickness of different reference insulation materials is given.The model proposed is a new design for rural housing roof insulation and energy-saving in severe cold region.

Key words:  severe cold region  rural housing  double-layer composite roof insulation  insulation material thickness
