摘要
以置换通风水平方向送风角度为变量,对设有冷却顶板和置换通风复合空调系统会议室室内环境进行动态模拟研究,并从气流温度场、速度场、PMV和PPD值等角度进行模拟结果分析.结果表明室内会议桌对空调房间气流场会造成较大影响;通过分析几组置换通风水平方向不同送风角度模拟结果,可知送风角度处在稍小于"临界角"范围内时较传统送风角度下的室内空气品质有所提高.
Taking the displacement ventilation air supply angle in horizontal direction as the variable, this paper does a study of dynamic simulation on the meeting room equipped with cooling ceiling and displacement ventilation air-conditioning system, and analyzed the simulation results of airflow temperature field, velocity field, PMV value and PPD value. Research results showed that the indoor obstacle had a large effect on the air flow field of the air-conditioning room. After the analysis of the displacement ventilation air supply angle in horizontal direction, it concludes that when the air supply angle in the interval is smaller than the critical angle, the indoor air quality will be better than that with traditional air supply angle
