摘要
通过建立相变地板蓄热供暖房间的三维物理模型以及室内空气温度场的非稳态传热数学模型,用Fluent软件对室内空气速度及温度分布进行模拟计算,并对模拟计算结果进行分析.研究结果表明,相对其它供暖方式而言,相变地板蓄热采暖的房间空气温度分布较均匀,在较低的空气温度条件下也可以达到同样的室内舒适性.相变地板采暖完全可以满足人们热舒适度的要求,同时也可实现节能、电力移峰填谷的目的.
The three-dimensional physical model and the unsteady heat transfer process mathematical model of under- floor heating system with PCM plates was developed. The study then calculated the speed and temperature of air inside simulation room with Fluent software and analyzed the result of the simulation. To be compared with other heating methods, the heating system with PCM can provide the well-proportioned temperature in the room. It can also meet to the same comfort standard in lower temperature condition. It is honestly indicate the PCM plates system can provide a good and warm environment. Besides, it can reduce consumption of power and balance electric providing.
