摘要 基于目前关于地板结构层热工性能的二维数值计算方法和解析计算方法的结果对比分析,采用当量热阻法提出相应的修正计算式,由此形成一种可适应于供冷工况地板结构层热工设计的半解析简化计算新方法。利用该方法,可快捷地评价所设计的地板结构层地板表面温度的分布以及供水温度与速度、埋管间距、地板饰面层材料、地板构造特性等因素对地板结构层传热性能的影响,为地板辐射供冷系统热工性能的优化设计提供新的思路和方法。 A simplified calculation method for the thermal design of floor structure was performed, which combined the numerical calculation with analytic method for 2D heat transfer of floor in radiant floor cooling system. The simplified method made it possible to conveniently estimate the floor temperature distribution and the influence of supply temperature, velocity, pipe spacing and floor construction on heat transfer performance of floor structure, and provide a new method and idea for the optimized design of thermal performance of radiant floor cooling system.
