摘要
简单介绍了舱外航天通风系统的结构、功能 ,分析了通风气体、液冷通风系统及环境间的换热过程 ,给出了通风系统传热数学模型。通过舱外航天液冷通风系统与人体的联合热生理实验对该模型进行了验证。
The structure and function are introduced simply about the ventilation system used for EVA (Extravehicular Activity), the heat transfer process is analyzed among ventilating gas, liquid cooling and ventilation system and environment, and a heat transfer mathematical model of ventilation system is developed. Thermal physiological experiment research has been carried out to verify this mathematical model, with the human body wearing LCVG (liquid cooling and ventilation garment) used for EVA in the experiment. This study provides a reliable basis for the design of ventilation systems of the space suit.
