摘要
对安徽某半开放的演出建筑冬季采暖设计进行了优化。论文采用数值模拟的方法,通过改变送风口的射流角度,对该建筑在3种不同空调供暖方式9种工况下的室内气流分布和热环境进行优化选择,从喷口尺寸,送风速度,喷口高度,喷口排列方式进行优化,对优化过的方案进行热舒适性分析,通过PMV、PPD等热舒适性指标验证优化方案的合理性,最终确定喷口送风+地面辐射复合供暖为最优方案。
The winter heating design of the performance building in Anhui Province was optimized. The paper uses numerical simulation method to optimize the indoor air distribution and thermal environment of the building under three different air conditioning modes. The nozzle size, air supply speed, nozzle height and nozzle arrangement was optimized,and the thermal comfort of the optimized solution was analyzed, and the rationality of the optimization scheme was verified through thermal comfort indicators such as PMV and PPD. It is finally determined that the nozzle air supply +ground radiation composite heating is the optimal solution.
