【摘要】 为了研究夏热冬冷地区低温辐射地板供暖影响因素，采用L₂₅（5⁶）的正交试验方法探究供水温度、管间流速、管径、管间距、填充层厚度5因素对地板表面平均温度和均匀度的影响，获得各因素对试验指标的影响趋势、显著性程度和组合的最优解。研究表明：对地板表面平均温度的影响程度为供水温度>管间距>管径>填充层厚度>管间流速，对均匀度的影响程度为管间距>供水温度>填充层厚度>管径>管间流速，最优水平组合为：供水温度取35℃,管间流速取0.4 m/s,管径取16 mm,管间距取100 mm,填充层厚度取75 mm。试验结果为夏热冬冷地区辐射供暖设计提供借鉴，亦可对数值分析软件与统计学的结合提供思路。更多还原

【Abstract】 In order to study the factors influencing low temperature radiant floor heating in hot summer and cold winter locales, the impacts of five variables—water supply temperature, inter-tube flow rate, tube diameter, tube spacing, and filler layer thickness—on the average temperature and uniformity of the floor surface were examined using the orthogonal test technique of L₂₅（5⁶）. The research demonstrates: water supply temperature>tube spacing>tube diameter>filler layer thickness>inter-tube flow rate has the most influence on the floor surface’s average temperature, while tube spacing>water supply temperature>filler layer thickness>tube diameter>inter-tube flow rate has the most influence on the floor surface’s uniformity. The ideal level combination is water supply temperature is taken as 35 ℃, inter-tube flow rate is taken as 0.4 m/s, tube diameter is taken as 16 mm, tube spacing is taken as the test’s findings serve as a guide for designing radiant heating systems for use in hot summer and cold winter climates. They also offer suggestions on how to combine statistics and numerical analytic tools.更多还原
