【摘要】 为了进一步完善干式地暖研究,了解干式地暖房间的热环境特点及系统的节能情况,掌握其热工特性,以大庆地区的地暖建筑为模拟对象,建立辐射供暖房间传热物理模型,利用Ansys软件,采用数值计算与理论分析相结合的研究方法,将干式地暖与湿式地暖的房间热环境进行比较。结果表明:在相同的进出水温度及室外计算温度条件下,干式地暖的室内温度、地板辐射温度、地板散热量均高于湿式地暖,且干式地暖比湿式地暖更节能。更多还原

【Abstract】 In order to study the thermal environment characteristics and energy-saving situation of the dry model radiant floor heating,Physical model of floor heating building was established in Daqing.An analysis software was used to compare the thermal environment between wet radiant floor heating and dry model radiant floor heating. The results showed that the indoor temperature,floor radiation temperature and floor heat radiation of dry model radiant floor heating were higher than those of wet radiant floor heating under the same inlet and outlet water temperature and outdoor temperature,and dry model radiant floor heating was more energy-saving than wet radiant floor heating.更多还原
