The cooling type evaporative cooling system for the outdoor sentry box of the present invention has a working process as follows:

In summer, especially when there is sunshine and heat, the evaporative cooling air-conditioning system is in operation; in cloudy or rainy days, the evaporative cooling air-conditioning system is in a stop working state.

1. Evaporative cooling air conditioning system, the working process of its wind system is as follows:

Outdoor fresh air enters the interior of the evaporative cooling air-conditioning system through the air inlet 1, and first passes through the pull-out filter 3 to filter out dust and debris to form clean air;

The clean air flows to the split packing-water distribution joint unit, part of the air flows through the first packing-water distribution joint device, and the other part of the air flows through the second packing-water distribution joint device; in the first packing-water distribution joint In the device, heat and moisture exchange occurs between the air flowing through the plant fiber filler a16 and the water film on the surface of the plant fiber filler a16 (the reason for the formation of the water film is that the water in the circulating water tank 12 is sent through the water supply pipe 18 under the action of the circulating water pump 15 To the water distribution pipe a2, the water is sprayed out by the water distribution pipe a2, and falls on the surface of the plant fiber filler a16 to form a water film), at this time, the air temperature is lowered; similarly, in the second filler-water distribution joint device, the water flowing through the plant The air in the fiber filler b17 and the water film on the surface of the plant fiber filler b17 undergo heat and moisture exchange (the reason for the formation of the water film is that the water in the circulating water tank 12 is sent to the water distribution pipe b4 through the water supply pipe 18 under the action of the circulating water pump 15, and is fed by the cloth The water pipe b4 sprays water out and falls on the surface of the plant fiber filler b17 to form a water film), at this time the air temperature is reduced;
