Abstract：Theoretical calculation and analysis were made on the air quantity and the number of air purification devices required for air purification according to the rapid purification requirements for CO2 and CO in the refuge chamber. The test of rapid purification capacity for CO2 and CO was carried out by taking a 50-person refuge chamber as the test platform, and through the test of 50 persons staying in the refuge chamber for 8 hours, the variation curve of the harmful gas concentration in the chamber and the metabolic rate of CO2 and CO by a single person under the condition of light labor intensity were obtained. The results showed that three air purification devices could meet the requirements for the rapid purification of CO2 in a 50-person refuge chamber and the purification requirements for CO2 and CO produced by real persons. For the rapid purification of CO, it should increase the number of the air purification devices and the air quantity.
