基于PMV的空调房间舒适性仿真分析与优化
Indoor comfort simulation analysis and optimization of air-conditioned rooms based on PMV
摘要:
空调房间内的气流组织是影响舒适性的重要因素。采用STAR-CCM+软件对冬季制热工况下某空调房间内的气流组织和热环境进行了数值模拟,对人体模型附近的速度场、温度场进行了分析,并对PMV进行了理论计算。结果表明:当导风板角度位于制热默认角度53°时,人体PMV整体偏高,舒适性较差;将默认导风板角度优化调整为28°后,舒适性明显提升。
Abstract:
Air distribution in air-conditioned rooms is an important factor affecting comfort. Simulates numerically the air distribution and thermal environment in an air-conditioned room under heating conditions in winter with STAR-CCM+ software, analyses the velocity field and temperature field around the mannequin, and calculates the PMV with theoretical method. The results show that, when the wind deflector angle is at the default heating angle of 53 degrees, the overall PMV of human body is high, and the comfort is poor, when the default wind deflector angle is optimized to 28 degrees, the comfort is significantly improved.
