建筑环境设计嵌入式辐射供暖和制冷系统的设计、尺寸确定、安装和控制第7部分:能量计算的输入参数

[中文适用范围]： 本文件规定了确定水基和电表面加热和冷却系统中相对于系统介质温差的热流的程序和条件。 水基表面加热和冷却系统的热性能及其与本文件的符合性的确定是根据设计文件和模型通过计算进行的。 这使得能够对水基表面加热和冷却系统进行统一评估和计算。 加热/冷却表面的表面温度和温度均匀性，水或电加热层与空间之间的标称热流密度，相关的标称介质温差，以及热流密度与确定值之间关系的特征曲线场变量作为结果给出。 本文件适用于住宅、商业和工业建筑中的水基嵌入式表面加热和冷却系统。 本文件也适用于电加热嵌入式系统。 这些方法适用于集成到墙壁、地板或天花板结构中且没有任何开放空气间隙的系统。 它不适用于未集成到建筑结构中的具有开放气隙的天花板安装面板系统。 [外文原描述]： This document specifies procedures and conditions to enable the heat flow in water-based and electrical surface heating and cooling systems to be determined relative to the medium differential temperature for systems. The determination of thermal performance of water-based surface heating and cooling systems and their conformity to this document is carried out by calculation in accordance with design documents and a model. This enables a uniform assessment and calculation of water-based surface heating and cooling systems. The surface temperature and the temperature uniformity of the heated/cooled surface, nominal heat flow density between water or electrical heated layer and space, the associated nominal medium differential temperature, and the field of characteristic curves for the relationship between heat flow density and the determining variables are given as the result. This document is applicable to water-based embedded surface heating and cooling systems in residential, commercial and industrial buildings. This document is also applicable for electrical heated embedded systems. The methods apply to systems integrated into the wall, floor or ceiling construction without any open air gaps. It does not apply to ceiling mounted panel systems with open air gaps which are not integrated into the building structure.
