[0035] The working principle of this utility model:

[0036] Working Principle 1:

[0037] In summer, fresh air is used for evaporative cooling. The summer air inlet valve 1 is opened, and the winter fresh air valve 7 is closed; the water pump 16 is turned on, and the water is distributed to the wet curtain 17 through the water distributor 4; the fan 11 is turned on; the fresh air is filtered through the filter cotton 9, and then evaporatively cooled and humidified through the wet curtain 17, and then the cold air is sent into the room through the air supply port 5 to achieve the summer cooling effect.

[0038] Working Principle 2:

[0039] When cooling down in winter, open the winter fresh air valve 7, close the summer fresh air valve 1, turn off the water pump 16; turn on the fan 11; the fresh air is filtered through the filter cotton 10, and then the cold air is sent into the room through the air supply port 5 to achieve the winter cooling effect.

[0040] Working Principle 3:

[0041] When humidifying and cooling in winter, open the return air valve 3, close the summer fresh air valve 1, and close the winter fresh air valve 7; turn on the water pump 16, and distribute water to the wet curtain 17 through the water distributor 4; turn on the fan 11, and the return air is humidified through the wet curtain 17, and then the cold air is sent into the room through the air supply port 5 to achieve the winter humidification effect.

[0042] Working Principle 4:

[0043] Automatic filter cotton replacement function. When the filter cotton is clogged due to fresh air filtration, the pressure difference sensor 18 senses the internal and external pressure difference to the set value. The roller curtain in the filter material storage bin 2 or 6 is opened to automatically replace the filter cotton, achieving the effect of automatic filter cotton replacement.

[0044] The utility model does not pass through the humidifying device in winter for the air inlet channel, passes through the humidifying device in summer, and passes through the humidifying device in winter for the return air channel. When the humidity in the machine room is lower than the specified value in winter, the return air channel is opened and humidified through the humidifying device.
