顶棚辐射桌面送风舒适性数值模拟研究

摘要

以人体周围的环境温度、风速和PMV值为指标,对顶棚辐射条件下的桌面送风热舒适性进行了数值模拟研究.以某一会议室为例,通过模拟确定了满足人体舒适性的桌面送风温度与速度参数.结果表明,顶棚辐射桌面送风时,在合理的送风参数下均能满足人体舒适性要求.%Taking the temperature, velocity and PMV of human environment as standard, human thermal comfort was researched for desktop task air-conditioning system combined with Ceiling Radiant Cooling Plate (CRCP). The reasonable parameters got, which could satisfy human thermal comfort at the conference room through numerical simulation. The results showed that the reasonable combination of the supply air temperature and velocity could satisfy human comfort requirements.
