民机客舱中太阳辐射对热舒适性的影响

乘客出行过程中对于热舒适度要求不断提高，对民机客舱的整体热舒适性提出了更加严格的要求。通过对南北飞行的航班实际测量发现，由于受到太阳辐射的影响，客舱内部向阳和背阴两侧温度分布极不均匀，特别是窗户周围，平均温差达到20℃，客舱向阳和背阴两侧的热舒适性相差较大；结合CFD动态仿真，基于实际客舱各区实时测量数据，建立等比例客舱仿真模型，以实际测量的温度和压力数据作为仿真边界条件，再现民机客舱内部温度和热舒适度PMV的分布情况，为定量分析南北飞行航班客舱的热舒适性提供理论依据。 

Effect of solar radiation on thermal comfort in civil aircraft cabin

The requirement of thermal comfort for passengers is constantly increasing, which puts forward more urgent requirements for the overall thermal comfort of civil aircraft cabin. Based on the actual measurement of flights flying from north to south, it is found that the temperature distribution on both sides of the cockpit is extremely uneven due to the influence of solar radiation, especially around the windows, the average temperature difference reaches 20℃, and the thermal comfort on both sides of the cockpit is quite different. Combined with the CFD dynamic simulation, based on the actual situation, the thermal comfort of the cockpit on both sides of the cockpit is quite different. Real-time measurements of temperature and thermal comfort PMV in the cabin of civil aircraft are reproduced by setting up a simulation model of equal proportion cabin. The simulation boundary condition is temperature and pressure data measured in practice. The theoretical basis for quantitative analysis of thermal comfort in the cabin of north-south flights is provided.
