摘　　要：为改善飞机地面空调恒定温度送风所造成的改舱客机舱内乘客热舒适性不佳的问题,建立了改舱后的Boeing 737客舱模型,并通过实验舱对仿真模型进行了试验验证,证明了此模型的合理有效性。在此改舱模型的基础上,运用CFD技术,模拟仿真出地面空调不同送风温度下,改舱客机的风速场与温度场,且针对改舱客机空调送风口与乘客座位距离不一致的特点,采用修正后的加权PMV评价客舱内的整体热舒适性,再结合EQT指标进一步研究每位乘客的局部热舒适性,最终得出满足热舒适性的最佳送风温度区间,为地面空调的合理送风提供理论依据。In order to improve the poor thermal comfort of passengers in the cabin caused by constant temperature air supply of aircraft ground air conditioning,the cabin model of Boeing 737 after the modification was established,and the simulation model was verified by experiments in the experimental cabin,which proves the rationality and effectiveness of the model.On the basis of this cabin modification model,the CFD technology was used to simulate the wind speed field and temperature field of the passenger aircraft at different air supply temperatures of the ground air conditioner.in view of the fact that the distance between the air supply port of the air conditioner and the passenger seat is inconsistent,the modified weighted PMV was used to evaluate the overall thermal comfort in the cabin,and then in combination with the EQT index,the local thermal comfort of each passenger was further studied.Finally,the optimal temperature range of air supply for thermal comfort was obtained,which provides a theoretical basis for the reasonable air supply of ground air conditioner.
