| 摘 要： | 本文建立了考虑绝热层向下传热的内嵌管式辐射地板传热的简化计算模型,并获取了其解析解。同时对该地板辐射传热进行了数值模拟,计算结果可作为评价解析解准确性的参考标准。计算结果表明,不考虑绝热层向下传热的地板表面温度及热流解析解结果与数值模拟结果有很大的差异;考虑绝热层向下传热的地板表面温度及热流解析解结果与数值模拟结果比较吻合,温度平均误差为0.22℃,热流平均相对误差为3.2%。

| Abstract: | In this paper,a simplified model for obtaining the analysis solution of pipe-embedded radiant floor was developed by considering the downward heat transfer through insulation layer.Numerical simulation for this floor was also conducted,which was taken as the benchmark for evaluating the analysis solution.The results shown the calculated surface temperature and heat flux by the analysis solution without considering the heat transfer through insulation layer had a big difference from the simulation results.However,the calculated surface temperature and heat flux by the analysis solution with considering the heat transfer through insulation layer agreed well with the simulation results.The average surface temperature error was 0.22 ℃,and the relative average error of heat flux was 3.2%. |
