摘　　要：共捕集技术是物化再生式环境控制与生保系统提质增效的有效途径,作为一种再生式共捕集技术,固态胺能够同时捕集二氧化碳和水,且吸附解吸条件温和,具有小型化、低能耗的潜力,非常适用于载人深空探测任务。当前国内外的系统不能很好地实现吸附与解吸的热交换,效率较低,综合优势不明显。本研究利用多物理场仿真手段优化了系统传热,设计了二氧化碳和水共捕集系统,验证了通风流量、切换周期等各项系统特性。结果表明:本研究中设计的多孔材料导热介质能够有效降低热阻,获取的系统最优装填比例和结构尺寸提升了系统传热效率;通过调节系统特性能够动态满足1~3名乘员不同代谢水平下的二氧化碳和湿度控制需求。本研究验证了再生式二氧化碳和水共捕集系统在重量、功耗和体积方面的优势,获得了系统特性规律,为载人深空探测任务提供了重要技术支撑。Gathering together is an effectual way for improving quality and efficiency of the physical and chemical regenerative environmental control and life support system,as a regenerative gathering together technology,solid amine can simultaneously gather carbon dioxide and humidity with mild adsorption and desorption conditions,thus having the potential for miniaturization and low energy consumption,making it very suitable for manned deep space exploration missions.The current domestic and foreign systems cannot achieve perfect heat exchange between adsorption and desorption,resulting in low efficiency and less obvious comprehensive advantages.This study utilized multi-physics simulation methods to optimize system heat transfer,designed a combined control system for carbon dioxide and humidity,and verified various system characteristics such as flow rate and cycle time.The results show that:The designed porous thermal conductive medium can effectively reduce thermal resistance,and the obtained optimal filling ratio and structural size improve the heat transfer efficiency of the system.By adjusting the system characteristics,it is possible to dynamically satisfy the carbon dioxide and humidity control needs for 1~3 crews at different metabolic levels.This study verified the advantages of the regenerative combined carbon dioxide and humidity gathering system in terms of weight,power consumption,and volume,and obtained system characteristics,providing important technical support for manned deep space exploration missions.
