地面顶棚联合作用辐射供暖房间热舒适性分析

Analysis on Thermal Comfort of Radiant Heating Room with Combined Consideration of Floor and Ceiling Temperatures

提出了在辐射供暖设计中,单一控制辐射体表面温度是不够的,必须综合考虑辐射体表面温度和邻室辐射体背面温度对房间舒适性的影响。采用PHOENICS软件模拟满足ISO7730标准的理论地面、顶棚温度范围,通过对标准房间实测及调查问卷对该温度范围的可靠性进行了验证,验证结果为可靠。

It is proposed that to control only surface temperature of radiator in radiant heating design is not enough, and the comprehensive consideration should be given to the influence of surface temperature of radiator and back temperature of radiator in adjacent room on the room comfort. The theoretical floor and ceiling temperature ranges satisfying ISO 7730 standard are simulated by PHOENICS software. The reliability of those temperature ranges is verified by measuring the standard room and the questionnaire investigation, and the result is reliable.
