摘要
飞机停靠站时,需要桥载空调来维持飞机客舱和廊桥内部的热舒适性,合理的桥载空调控制既能保证要求的舒适程度,又可实现节能环保。为此对飞机客舱与登机廊桥环境进行数值模拟(CFD),分析其温度场和速度场,应用两者内部的空气分布特性和温度、风速的不均匀系数作为热舒适性评价指标,研究桥载空调送风速度与飞机客舱和廊桥内部热舒适性的关系。研究显示只有当送风速度选取适当才能保证空气分布特性指标(ADPI)取得最大值,在最佳送风速度时,不同的气流组织形式对热舒适性的影响不同,均匀的送风模式能更好地满足人们对热舒适性的要求。CFD研究得到的桥载空调送风速度及送风模式与热舒适性的关系,可为桥载空调的合理控制提供依据。
Bridge-load air conditioning is used to maintain the thermal comfort inside aircraft cabin and lounge bridge when an aircraft docks at airport. Reasonable bridge-load air conditioning control should keep the required thermal comfort, and realize energy saving for environmental protection. Numerical simulation （CFD） of aircraft cabin and lounge bridge environment including temperature field and velocity field is made. ADPI （air diffusion performance index）, irregularity coefficient of temperature and speed are chosen as thermal evaluation indicators to study the relationship between fresh air supply speed of bridge-load air conditioning and thermal comfort inside the aircraft cabin and lounge bridge. CFD simulation results show that only when the speed of air supply is set appropriately, the ADPI reaches maximum. With the optimum air supply speed, different modes of air supply have different effect. Uniform air supply mode is better than central air supply mode. The results will improve bridge-load air conditioning control.
