标准摘要
[中文适用范围]: 本文件规定了确定水基表面加热和冷却系统中相对于系统介质温差的热通量的程序和条件。 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。 结果给出了加热/冷却表面的表面温度和温度均匀性、水与空间之间的标称热通量、相关的标称介质温差以及热通量与决定变量之间关系的特征曲线场。 本文件包括基于有限差分或有限元方法的通用方法以及取决于管道位置和建筑结构类型的简化计算方法。 [外文原描述]: This document specifies procedures and conditions to enable the heat flux in water-based 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 flux between water and space, the associated nominal medium differential temperature, and the field of characteristic curves for the relationship between heat flux and the determining variables are given as the result. This document includes a general method based on finite difference or finite element Methods and simplified calculation methods depending on position of pipes and type of building structure.
