飞机座舱温度扰动实验研究

Experimental Investigation on Temperature Disturbance in Aircraft Cabin

为研究飞机座舱引气温度扰动对座舱温度及舒适性的影响,在波音737飞机五排模拟座舱中分别采用天花板和天花板+侧壁两种送风形式进行座舱温度扰动实验。改变座舱引气温度,测量座舱总体和局部温度变化过程并简单评价了座舱的热舒适性。结果表明:引气状态相同,天花板送风对应的温度扰动值为0.32℃,天花板+侧壁对应的温度扰动值为0.59℃。两种送风形式所对应的座舱内总体温度平均值基本相等,为23.5℃,而天花板+侧壁送风形式使局部位置温度更接近人体舒适感觉温度范围。

In order to investigate the influence of temperature and thermal comfort caused by temperature disturbance of ventilation in aircraft cabin,experiments of temperature disturbance under both ceiling and side plus ceiling ventilation type were implemented respectively in a cabin mock-up of Boeing 737 which contains five rows of seats. The temperature of ventilation air was changed then the process of whole and local temperature changes in cabin mock-up was measured,the thermal comfort was assessed simply as well. The results indicate that the disturbed value of these two ventilation types is 0. 32 ℃ and 0. 59 ℃ positively under the same ventilation condition. The main temperature average value under both ventilation types are equal to 23. 5 ℃ approximately,but temperature under side plus ceiling ventilation type is more close to the range of people's comfort sensation in some parts of the cabin mock-up.
