【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。
[Abstract]:In order to study the thermal comfort of human body in aircraft cabin, it is necessary to optimize the control of bridge-borne air-conditioning. In the analysis of thermal comfort, a reasonable human body model should be established, and a simplified human body model with the ability to adjust temperature should be established, aiming at the defects of the previous fixed surface temperature method and constant heat flow method, and a simplified human body model with the ability to adjust temperature should be established. The numerical simulation model of three-dimensional flow field and temperature field in cabin is established by using PMV (forecasting average number of votes) as the evaluation index of thermal comfort and using CFD software. According to the height specified in the ASHRAE standard, the data sampling points were established in the head and other parts, and the variation of PMV with the velocity of the air supply was obtained in the vicinity of different parts of the body. The simulation results show that the human body feels comfortable when the supply air temperature is constant and the air velocity is between certain values. The simulation results provide some references for the optimal control of bridge-borne air-conditioning.
