严寒地区村镇住宅节能体型系数研究

Shape coefficient of energy efficiency of rural residence in severe cold region

我国严寒地区村镇住宅冬季采用分户乡土式采暖方式,采暖期达半年之久,采暖能耗很大.为了提出国家标准《村镇住宅节能设计标准》中有关严寒地区的节能体型系数的控制性指标,本文在严寒气候区实测了57户村镇住宅,通过数理分析,得出了体型系数的实际情况;针对影响严寒地区住宅建筑体型系数的平、剖面形式,面积大小,栋深组合长度等因子进行分析,提出了减少体型系数的各种因子参数控制范围;提出了按照层数不同,分别确定体型系数的结论,一层住宅建筑体型系数宜<0.75,二层住宅建筑体型系数宜<0.59.

Chinese rural residence in severe cold regions uses local type heating in winter.Heating period is six months and the energy consumption of heating is huge.In order to raise the controlling index about shape coefficient of energy efficiency in the ＂design standard for energy efficiency of rural residence＂,the paper measured 57 rural residences in severe cold regions and got the shape coefficient by mathematical analysis.The control range of different factors on reducing shape coefficient according to Plane form,Profile form,acreage,length of building depth group,and slope of roof,which affect the shape coefficient of rural residence in severe cold regions were presented.The shape coefficient can be got according to the floor quantity.The shape coefficient of one-layer residence should be less than 0.75,and that of two-layer residence should be less than 0.59.
