Abstract

A physical and mathematical model is proposed, which describes oxygen regeneration and carbon dioxide reduction in a closed system. The system is constructed by considering a man lives in a closed chamber where chlorella is cultivated in a pool of water. Human consumes oxygen and gives out carbon dioxide by respiration in the gas phase. And chlorella takes in carbon dioxide and gives out oxygen in the liquid phase. Computer simulation of the process is carried out by solving a series of S-system differential equations in logarithmic space. The simulation results show that oxygen regeneration and carbon dioxide reduction can be realized in Controlled Ecological Life Support System(CELSS) by means of cultivating chlorella.
