【摘要】 本文针对一个实际的壁挂式空调房间,建立了模型并进行数值模拟研究,模拟了在制热工况条件下,不同羽根扫风角度的房间内有效区流场和温度场,并对有效区选取测点进行舒适性和均匀性评价。结果表明:在制热运行时,空调羽根左右扫风功能对房间内的热舒适性、温度及速度的均匀性都有明显的改善。羽根左右扫风的角度对房间内有效区的热舒适性及均匀度都有很大影响,在本文研究中,羽根左右扫风角度90°(工况B)相对于其他几种工况,热舒适性和温度及速度均匀性最好,制热效果最好。更多还原

【Abstract】 The distribution characteristics of airflow and temperature field in an actual room with wall airconditioner were studied under different swept angle of fin when the air-conditioner was running at heating condition.Then the impact of fin swept angle on thermal comfort and uniformity was analyzed by choosing measure points in effective area.The results show that when the air-conditioner was running at heating condition,fin swept function can improve the thermal comfort and uniformity of temperature and velocity in room.Meanwhile,swept angle of fin has great impact to thermal comfort and uniformity in effective area.In this article,when swept fin angle is 90,effective area has the best thermal comfort,best temperature and velocity uniformity and highest temperature.更多还原
