摘要
基于不同的气流组织利用CFD技术对空调客房室内的速度场、温度场、PMV、PPD值进行数值模拟,通过对3种气流组织速度场、温度场比较,结果显示散流器送风能够得到均匀的温度场、速度场。同时,PMV、PPD值更靠近推荐值范围,热舒适性更好,从而为改善空调客房的热舒适性设计提供了方法和理论依据。
Based on the different air supply mode and using the CFD method makes numerical simulation about the velocity field,the temperature field,the PMV and PPD of the air conditioning room.Through comparing of the velocity field and the temperature field on three typical air distribution forms,the result indicates that the best way is air diffuser that can obtain uniform temperature field and velocity field.In addition PMV and PPD values are closer to range of recommended values and thermal comfort is more better which provides the method and the theoretical basis to improve the thermal comfort of air-conditioning rooms.
