摘　　要：从散热机理、舒适性和节能性等方面,对比分析了散热器、低温地板辐射、毛细管平面辐射、电热膜辐射等供暖方式的特点,并计算了此四种供暖方式的熵值变化。结果表明:地板辐射供暖符合人体"脚暖头凉"的舒适性理论;毛细管平面辐射供暖最舒适、最节能,是最值得推广的供暖方式。In view of heat rejection mechanism, thermal comfort and energy saving, the features are analyzed in regard to radiator, low-temperature radiant floor, capillary radiant plane, electric thermal film heating mode and so on, and their entropy changes are also calculated with entropy principle. The analysis indicates that floor heating is mostly in line with the principle of ＂warming feet instead of head＂ and capillary radiant plane heating is of the greatest comfort, efficiency and energy saving, thus bing the most valuable for promoting.
