摘要
低温地板辐射供暖地板与外围护结构内表面存在辐射换热 ,散热器供暖房间的散热器附近以及散热器上部热气流与外围护结构存在热流短路。文章在低温地板辐射供暖室比散热器供暖房间室内设计温度降低2℃的情况下 ,分别对三个典型地区这两种供暖方式在上述情况下造成的房间热负荷和供暖季平均耗热量进行计算。结果表明此条件下 ,低温地板辐射供暖房间的热负荷可降低 1 0 %～ 1 5 % ,节能率约为 1 5 %～ 2 0 %。
The composing of heating load in a typical room with radiant floor heating system or radiator heating system was analyzed. Then, the heating load and heat loss of the room with two systems in three typical city were calculated respectively under the condition that the indoor air design temperature of radiant floor heating is 2 ℃ lower than that of radiator heating. Result shows that 10% to 15% of heating load and 15% to 20% of heat loss can be saved in radiant floor heating systems compare to radiator heating systems.
