The Effects of Fluctuations in Plant Growth Rate on Material Circulation in ECLSS | CU Experts

An Environmental Control and Life Support System (ECLSS) is; an essential system for living in outer space. Beyond; low-Earth orbit, where resupply becomes more difficult, it; is necessary to regenerate and circulate more of the; materials in the system. To increase the regeneration rate; of substances from the current level and close the material; circulation, a hybrid system of physicochemical and; bioregenerative processes will become essential. One of the; major problems with bioregenerative processing is the; uncertainty of the processing amount. In this paper, we; focus on plant cultivation as a method of food production,; oxygen regeneration, and carbon dioxide reduction. We; calculated the changes in input and output amounts by; changing the plant growth rate of a plant growth model. As; a result, there is a large impact on the material; circulation environment, and it is necessary to design; physicochemical treatment equipment that can absorb these; effects.
