针对目前围护结构蓄热性能评价方法和指标不能有效评价蓄热量的问题,该文基于"日间热容"概念和有限差分法,提出一种新的围护结构蓄热性能评价方法和相关指标.该方法可获得围护结构逐时动态蓄热量、不同构造层次的蓄热情况以及材料层和围护结构在一定时间段和一定面积内的累积蓄热量.以一个简化的建筑模型为例,运用该方法得出建筑不同朝向、不同部位围护结构各材料层的蓄热量情况.该文的方法可为建筑围护结构实际蓄热效果提供系统全面的定量评价,为太阳能建筑分朝向、分部位的蓄热设计提供方法和依据.
Aiming at the problem that the evaluation method and index of heat storage performance of enclosure structure cannot effectively evaluate heat storage,a new evaluation method and related index of heat storage performance of enclosure structures are proposed based on the concept of diurnal heat storage capacity and finite difference method.The method can obtain the hourly dynamic heat storage of the enclosure structures,the heat storage of different structural levels and the accumulated heat of the material layer and the enclosure structure in a certain period of time and a certain area.Through a simplified building model,this paper obtains the heat storage of different material layers of building envelope in different directions and different parts.The method in this paper can provide a systematic and comprehensive quantitative evaluation method for the actual heat storage effect of building envelope structure,and also provide a method and basis for the design and layout of solar energy buildings in different directions and parts.
