摘要
为建立验证并完善模块带腔地板辐射供暖系统的CFD数值计算模型,运用数值计算模型对影响模块带腔地板辐射供暖系统的参数进行分析.建立模块带腔地板辐射供暖系统的计算模型,利用CFD软件进行模拟计算,分析供回水温度变化时地板表面平均温度,并与实验测得的数据进行对比,验证模型的正确性.利用验证后的模型,分析盘管间距对地板表面温度的影响.结果表明:所建立的CFD数值计算模型与计算方法是可行的;在供回水平均温度相同情况下,地板平均温度模拟结果与测试结果均存在1℃左右偏差,但相对偏差可以控制在5%以内.结论:盘管间距越大,模块带腔地板辐射供暖系统地板表面温度相对越低,间距对本系统的影响不可忽视.
In order to build, validation and improve CFD numerical calculation model of floor radiant heating system with cavity, influencing parameter of floor radiant heating system with cavity was analyzed using numerical calculation model. The calculation model floor radiant heating system with Cavity was built and simulated by using CFD software Fluent. The return water temperature changes in the average floor surface temperature was analyzed, and compared with the experimental measured data. Using the validated model and by changing model coil spacing, the study analyzed the effect of coil spacing on the floor surface temperature. The study results show that the established CFD numerical calculation model and calculation method is feasible. Under the same return water L temperature, floor temperature simulation results and test results are with difference of 1 ~C, and the deviation can be controlled within 5%. The coil spacing greater floor surface relative temperature of floor radiant heating system with cavity the lower, spacing influence can not be ignored.
