At both ends of a closed space, more than one set of honeycomb-shaped water curtain frames and exhaust fans are respectively installed. When the water flow of the water storage tower enters the nozzle hole of the supply water inlet pipe, the water flow in the upward direction is sprayed in an arc shape. A large number of water droplets are formed on the inner surface of the board, and the water droplets are evenly sprinkled on the cardboard, so that the whole cardboard is completely wet and absorbs water after receiving water. At this time, the exhaust fan must be activated to blow the indoor heat and dirty air to the air. At the same time, when the external airflow passes through the frame of the water curtain sheet, it mixes with the water vapor of the water curtain sheet, and after being fully saturated with water, it immediately cools down to a low-temperature airflow, and then fills the entire indoor space, resulting in a smooth flow of airflow. Refreshing effect. When the supply of cold water is sprayed on the entire cardboard of the water curtain sheet, the cardboard will be completely dampened to absorb water. After the cardboard is saturated, the water will drip into the water collection tank, and then go to the water storage tower for purification treatment, so that the water can be recycled.

In the utility model, the cardboard of the multi-lane and continuous undulating water curtain sheet forms a diamond-shaped space with two high points or two low points facing each other to form a honeycomb area.

In the utility model, a breathable sunshade net is attached to the frame of the water curtain, and the supply of external airflow can be regulated through the degree of coverage of the sunshade net.
