摘要
本文利用组合式电热辐射板实验研究了电加热地板采暖辐射板内的传热特性。研究结果表明:辐射板的结构材料及其物性参数对表面温度分布和采暖能耗具有重要的影响。即使在实验条件下加热板内各层温度,使其呈周期性波动,但室内地板表面温度分布仍然非常均匀。在辐射板的热量损失中,通过辐射板下表面的损失热量接近辐射板全部的热量损失。
In this paper, the heat-transfer characteristics of the heating panel of an electric heating radiation floor system were investigated. The experimental results showed that the material and characteristics of heating panel have a great influece on the surface temperature distribution and the energy consumption. Although the temperature inside the panel fluctuated periodically in the experiment, the temperature on the surface of the panel was basically uniform. The heat loss through the under surface of the electric radiant panels was almost equal to the total heat loss of the radiant panel.
