    • Abstract
  • We build survival simulation test system and test its tightness and make it has the basic function of refuge chamber to provide an efficient and fast experimental platform for research environmental parameters of refuge chamber. What's more, we found out that the more pressure difference between external and internal of refuge chamber, the faster speed of air leakage rate. Above all, we should avoid too much pressure difference to improve the usage of compressed gas in refuge chamber under the condition of the limited number of stored compressed gas in the interior department of chamber.
