摘要
该文提出了以一种定形相变材料作为贮热介质的新型地板辐射采暖系统 ,建立了相应的理论模型 ,并作了数值模拟。研究发现熔点在 32℃左右的定形相变材料是该系统较理想的贮热材料。计算结果表明相变贮能式地板辐射采暖系统控制简单 ,不仅节省能源 ,而且能提供舒适的热环境。
In this work, a novel radiant floor heating system utilizing a kind of form stable phase change material (PCM) as the thermal mass is investigated numerically. A theoretical model is presented to simulate the thermal performance of the system. It was found out that a form stable PCM with a melting point of 32℃ is an ideal candidate for the system. The results showed that such a system is energy officient and can provide a good thermal environment with simple control strategy.
