“天宫二号”空间实验室密封舱热舒适性评价
|
摘要
基于在轨飞行数据,采用PMV(predicted mean vote)方法对"天宫二号"空间实验室密封舱热舒适性进行评价,获得了密封舱热舒适性值;并将其与"神舟十一号"载人飞船和"天宫一号"目标飞行器密封舱热舒适性进行比较,分析热舒适性差异存在的原因,以及密封舱空气温度、相对湿度和舱壁温度对热舒适性的影响,结果表明空气温度对热舒适性影响最为明显。本研究可为后续载人航天器密封舱热设计提供参考。
The thermal comfort of the airtight cabin of the Tiangong-2 space lab is assessed using the PMV model based on the flight data,as compared with that of the Shenzhou-11 manned spaceship and the Tiangong-1target vehicle.The causes of the difference are discussed.The influence of the air temperature,the relative humidity and the temperature of the cabin wall on the thermal comfort are discussed in detail,which indicates that the air temperature is the most important factor.The result may serve as a reference for the thermal design of subsequent manned spaceships.
