摘要
通常以稳定传热过程代替不稳定的传热过程,在工程上虽然是允许的,但并没有反映出围护结构与热耗的本质。论述了不同地区围护结构的热阻和节能率的关系,从而为建筑节能提出理论根据。以严寒地区保温房为例,给出采取的保温措施,由于热阻变大,增加了外墙内表面的热稳定性。改进外围护结构热工性能通常是利用新的保温材料并使其应用在围护结构中,工程实际证明,已取得了明显的效果。
In civil engineering constant heat transmission is often employed to replace non-constant heat transmission,It is allowed in construction,but the relation between enclosing structure and heat consumption is not shown clearly,This paper deals with the relation between the heat resistance of enclosing structure and the rate of energy saving,and puts forward theoretical grounds for energy saving in civil engineering.Heat preservation measures are given for buidings in cold regions.Heat stability of the inner side of the wall is improved because of the increased heat resistance.New heat preservation materials are generally used to improve the heat engineering of the outer enclosing structure.Field application shows that good results have been achieved.
