چکیده انگلیسی

The personnel in refuge chamber absorb O2 and exhale CO2 all the time. Supplying O2 and removing CO2 are the basic function of refuge chamber. After disaster occurs, the supply of the compressed air or oxygen for personnel in refuge chamber is limited. Thus, how to effectively use the compressed air and oxygen and try to improve the time of supply has a great significance. Supplying more oxygen will result in waste, while supplying less oxygen will cause its concentration to be lower, and harm life safety. This research uses the theoretical calculation and numerical simulation, finds critical gas supply for refuge chamber, and illuminates the change law of gas concentration with critical gas supply in refuge chamber, which provides theoretical guidance for effective use of compressed air and oxygen in refuge chamber.
