| 摘 要： | 建立了干式地板辐射供暖系统传热模型并编制相关软件,对软件计算值作实验验证的结果表明,地板表面平均温度的软件计算值与实验值误差小于10%,作用温度误差在3%范围内.应用软件计算得出,地板表面平均温度、室内空气温度和作用温度随管间距的增加而降低,随供回水平均温度的升高而升高,且室内空气温度变化率小于地板表面平均温度变化率.实验研究表明,水平和竖直方向作用温度分布均匀,竖直方向作用温度出现正的温度梯度.系统稳定时辐射换热量占总换热量的份额约为60%,但相对于湿式地面供暖,地板表面温度分布均匀性略差.

| Abstract: | Presents the heat transfer model and develops the corresponding software. The experimental results show that the error between software calculation value and experimental result of the average floor temperature is less than 10 % and that of the operation temperature is 3 % . Based on the software calculation concludes that the average floor temperature,indoor air temperature and operation temperature are decreased with increasing of the tube spacing and increased with increasing of the average temperature o... |
