摘　　要：模拟了低温地板辐射供暖与对流散热器供暖系统在不同太阳辐射照度下的动态热过程。对比了室内温度及供暖耗热量等指标,结果表明在高太阳辐射照度地区地板辐射供暖系统室内过热现象更明显,地板辐射供暖能耗与散热器供暖能耗比值随太阳辐射照度的增大而增加,因此选择高太阳辐射照度地区的供暖形式时应优先采用热响应较快的散热器供暖形式。Simulates the dynamic thermal process of the low temperature floor radiant heating system and the convector heating system under different solar irradiances. Comparing the indoor temperature and the heating energy consumption of the two systems, the results show that the over heating with the low temperature floor radiant heating system is more notable, and the heating energy ratio of the radiant system to the convective system is increasing with the solar irradiance. Concludes that the convector heating system is more desirable than the low temperature floor radiant heating system in the areas with higher solar irradiance.
