The outer wall of the return air section 3 is also provided with a fresh air inlet 34, and a rain cover 35 is installed above the fresh air inlet 34, which can prevent rainwater from entering the inside of the box 1, thereby ensuring the normal operation of the system.

[0045] The outdoor air enters the return air section 3 through the fresh air inlet 34, and the return air in the air film building 2 enters the return air section 3 through the return air valve 32, and mixes with the outdoor air in the return air section 3.

[0046] Preferably, in the embodiment, the return air section 3 and the heat exchange section 6 are also connected with a filtering section 5, which is used for filtering the inhaled air.

[0047] A disinfection and sterilization section is also provided between the filtering section 5 and the heat exchange section 6, which is used for disinfecting and sterilizing the filtered air. Ultraviolet lamps or other disinfection equipment are used to sterilize the air to improve the air quality.

[0048] After the air in the return air section 3 is filtered by the filtering section 5, it enters the disinfection and sterilization section, and after the disinfection and sterilization treatment in the disinfection and sterilization section, it enters the heat exchange section 6.

[0059] The pressure maintaining mode is a mode in which the return air valve 32, the exhaust air valve 33, the cold water heat exchange coil 61 and the spray heat exchanger 62 are all closed and each of the fans 71 is turned on.

[0060] It should be noted that in the circulation mode, the exhaust air valve is automatically opened or closed according to the carbon dioxide concentration in the air film building 2, and the control mode is a prior art.

[0061] Preferably, in the embodiment, the controller is a PID proportional integral controller, the fan 71 is a variable frequency fan 71, and the fan 71 operates according to the frequency adjustment of the air film pressure in the three operation modes. Through the PID proportional integral controller and the variable frequency fan 71, the working frequency of the fan 71 can be automatically adjusted according to the pressure in the air film, so as to realize accurate pressure maintaining control.
