内保温住宅的户间传热温差

以目前新建住宅中较为普遍的钢筋混凝土内保温外墙、陶粒混凝土内墙结构的居住建筑为对象，建立房间不稳态传热的数学模型，通过数值求解，得出了四种典型房间，在北京地区供暖室外设计温度下，采用分室调节最低值（即停止采暖）时，其室温和邻室的户间传热温差及房间围护结构温度分布的变化规律，为进行住宅按户计量供暖设计热负荷的确定，提供了户间传热计算的依据，也为按户计量收费和建筑保温及防结霜研究提供了参考依据。

Heat Transfer Temperature Differences between Houses with Inner Thermal Insulation

Based on the house with reinforced concrete and inner thermal insulation for external wall and ceramsite concrete for internal wall that is common in newly building houses at present, this paper establishes the mathematical model of room unsteady heat transfer at the heating calculating temperature out of the door. By means of numerical solutions, the variation patterns of the indoor temperature, the temperature differences between the room of a study object and its neighbor rooms and the temperature distribution of the envelope were obtained at the lowest point of regulation i.e. when stopping heating for four kinds of typical rooms. The result can be adopted for reference in calculating the transferred heat between neighbored rooms for determining system heat load of household based heat metering heating system designing,and charging ,in building thermal insulation and in protecting frost study.
