标准范围

ISO 13370:2017提供了与地面热接触的建筑构件的传热系数和热流率的计算方法，包括地上楼板、悬挂式楼板和地下室。它适用于位于建筑物边界墙水平面下方的建筑图元或其部分-在地板内表面的水平面上，对于地面上的楼板、悬挂式地板和未供暖的地下室；注1:在某些情况下，外部尺寸系统定义了楼板下表面的边界。-在外部地面的水平面上，用于加热地下室。ISO 13370:2017年包括计算稳态传热部分（年平均热流率）和因温度的年周期性变化引起的部分（热流率的季节性变化约为年平均值）。这些季节性变化按月获得，除附录D中的动态模拟程序外，ISO 13370:2017不适用于较短的时间段。注2:引言中的表1显示了ISO 13370:2017在ISO 52000-1规定的模块化结构背景下在EPB标准集内的相对位置。

ISO 13370:2017 provides methods of calculation of heat transfer coefficients and heat flow rates for building elements in thermal contact with the ground, including slab‐on‐ground floors, suspended floors and basements. It applies to building elements, or parts of them, below a horizontal plane in the bounding walls of the building situated- at the level of the inside floor surface, for slab‐on‐ground floors, suspended floors and unheated basements;NOTE 1 In some cases, external dimension systems define the boundary at the lower surface of the floor slab.- at the level of the external ground surface, for heated basements.ISO 13370:2017 includes calculation of the steady‐state part of the heat transfer (the annual average rate of heat flow) and the part due to annual periodic variations in temperature (the seasonal variations of the heat flow rate about the annual average). These seasonal variations are obtained on a monthly basis and, except for the application to dynamic simulation programmes in Annex D, ISO 13370:2017 does not apply to shorter periods of time.NOTE 2 Table 1 in the Introduction shows the relative position of ISO 13370:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.
