摘　　要：研究飞机客舱内人体热舒适性,需对桥载空调的控制进行优化。在热舒适性分析中,应建立合理的人体模型,并针对以往定表面温度法和定热流法的缺陷问题,建立了具有温度调节能力的简化人体模型,采用PMV(预测平均投票数)作为热舒适性的评价指标,运用CFD软件对客舱内三维流场和温度场建立了数值仿真模型。按照ASHRAE标准的规定的高度在头部等部位建立数据采样点,计算得到了身体不同部位附近PMV随送风速度变化的情况。仿真结果表明,当送风温度不变,送风速度在一定值之间时人体热感觉舒适,仿真结果为桥载空调优化控制提供了相关参考。The studies about thermal comfort analysis in aircraft cabin are of great significance for the reasonable control of air-conditioning under the Corridor bridge. In the analysis of thermal comfort,reasonable human body model is critical. Giving the defeats of the traditional methods of fixed surface temperature and constant heat flux,the paper established a simplified human body model capable of temperature regulation. Taking Predicted Mean Vote（ PMV） as the thermal comfort evaluation index,CFD software was applied for numerical simulation of three-dimensionflow field and temperature field in cabin. In accordance with the provisions of the ASHRAE standard,the sampling points of specific heights on the head and other parts of human body were established,and the change trend of near different parts of human body PMV value under different air supply velocity was calculated and obtained. The simulation results show that when air supply temperature is constant,air supply velocity keeps a certain value,and the thermal sensation is comfortable. The results provide a reference for the control of air-conditioning under the Corridor bridge.
