Otherwise, when the oxygen proportion 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 proportion in the defense collecting space 10.
And when the oxygen proportion is smaller than the preset value and the pressure difference is larger than the first preset difference value and the blower of the booster fan 14 is started, the frequency of the booster fan 14 is increased and the opening degree of the pressure release valve is increased.
When the oxygen proportion is greater than or equal to a preset value, the pressure difference is greater than a first preset difference value, and when the radiation and/or biochemical pollutants are detected outside the centralized protection space 10, the opening degree of the pressure release 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 gas to enter the centralized protection space 10 is treated by the medium-efficiency filter 16, the carbon adsorption device 17 and the nuclear-grade high-efficiency filter 18.

For example, the first evaporator 45 is turned on to perform dehumidification according to an excessive humidity outside the waterproof collecting space 10. When the temperature outside the containment space 10 is lower than the temperature inside the containment space 10, the heater 13 is turned on, and the condensing unit 42 may be used to perform auxiliary heating.
When the purification module 22 is turned on, the second evaporator 46 is controlled to be turned on or off according to the temperature and humidity in the defense collecting space 10. When one or both of the temperature and the humidity in the defense collecting space 10 are higher than the corresponding preset values, the second evaporator 46 can be controlled to be turned on to cool or dehumidify.
