That is, the radiation and/or biochemical contaminants within the defense space 10 are treated to be the most preferred level to secure the environment within the defense space 10.

Otherwise, when the oxygen ratio is smaller than the preset value, the booster fan 14, the first electric air valve 31 and the third electric air valve 33 are opened to increase the oxygen ratio in the air collecting and preventing space 10.
And, when the oxygen ratio is smaller than the preset value and the pressure difference is larger than the first preset difference, and when the blower of the booster fan 14 is turned on, the frequency of the booster fan 14 is increased and the opening of the pressure reducing valve is increased.
When the oxygen ratio is greater than or equal to the preset value and the pressure difference is greater than the first preset difference, and when the radiant and/or biochemical pollutants are detected outside the collecting and preventing space 10, the opening of the pressure reducing valve is increased, and the booster fan 14, the first electric air valve 31 and the fourth electric air valve 34 are opened, so that the medium-efficiency filter 16, the carbon adsorption device 17 and the nuclear-grade high-efficiency filter 18 process the gas to be introduced into the collecting and preventing space 10.

When the booster fan 14 is turned on, the first evaporator 45 and the heater 13 are controlled to be turned on and off according to the temperature and humidity in the air collecting and preventing space 10 and the temperature and humidity outside the air collecting and preventing space 10. For example, the first evaporator 45 is turned on to dehumidify according to the excessive humidity outside the trap space 10. When the temperature outside the defense space 10 is lower than the temperature inside the defense space 10, the heater 13 is turned on, and the condensation module 42 can be used for auxiliary heating.
When the purification module 22 is turned on, the second evaporator 46 is controlled to be turned on and off according to the temperature and humidity in the defense space 10. When one or both of the temperature and the humidity in the air collecting and preventing space 10 is higher than the corresponding preset value, the second evaporator 46 can be controlled to be started for cooling or dehumidifying. When none of the booster fan 14, the purification module 22 and the second electric air valve 32 is turned on, the synchronous start and stop of the sixth electric air valve 36, the air conditioner fan 21, the second evaporator 46 and the fifth electric air valve 35 are controlled according to the temperature and humidity in the air collecting space 10.
