Carbon dioxide accumulation of space station crew quarters

  • In order to analyze the accumulation process of CO2 expired by crew in pressure cabin without proper ventilation and to evaluate the possible medical hazards, a computational fluid dynamics (CFD)model of crew staying in a given space station quarter was built to simulate the unsteady process of respiration. The concentration of CO2 in exhaled air and the pulmonary ventilation varied with the concentration of CO2 in the inhaled air based on physiological experiments. The results for partial pressure of CO2 at typical locations and different intervals were presented based on simulation. Finally, a maximum allowable time that crew can stay in quarters without ventilation, some placement principles of CO2 monitors and some precautions ensured crew-s life safety in similar conditions were proposed.
