摘要:

众多学者对冬季睡眠热舒适的研究表明,人体在夜间睡眠状态下对温度的需求低于白天水平。在此基础上,对太阳能供暖的常用末端方式——地板辐射供暖系统与低温强制对流散热器供暖系统进行了实测。结果显示:低温强制对流散热器供暖工况下的太阳能保证率比地板辐射供暖高7%左右;夜间降低供暖温度后,地板辐射供暖和低温强制对流散热器供暖的太阳能保证率均提高11.5%。

Abstract:

Many scholars’ studies on thermal comfort during winter sleep show that the human body’s demand for temperature during night sleep is lower than the daytime level. On this basis, measures the common terminal modes of solar heating—floor radiant heating system and low-temperature forced convection radiator heating system. The results show that the solar guarantee rate of low-temperature forced convection radiator heating is about 7% higher than that of floor radiant heating, and after lowering the heating temperature at night, the solar guarantee rate of floor radiant heating and low-temperature forced convection radiator heating both increases by 11.5%.
