The characteristics of combined carbon dioxide and humidity gathering system based on solid amine
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.
