Humidification and purification requirements.

The technical solution adopted by the utility model is, an evaporative cooling fresh air window with louvers that can force air supply, and an air inlet and an air supply port are respectively arranged on the opposite side walls of the unit casing, and the outside of the unit casing, the air inlet There are louvers, and in the casing of the unit, there are filter screens, packing a, packing b and axial flow fans in sequence according to the direction of air entry. The upper part of packing a is equipped with dripping nozzles for downward spraying. The lower part is provided with a water collecting tank, and the circulating water pump is connected with the water collecting tank, the low-pressure water supply pipe and the dripping nozzle through pipelines.

The utility model is also characterized in that,

The thickness of filler b is half of that of filler a.

The water collecting tank is provided with a water filter, and the water filter is connected with the circulating water pump through a pipeline. the

Compared with the fresh air window of the prior art, the fresh air window of the utility model has the following characteristics:

1) Install louvers in front of the air inlet to flexibly adjust the air supply volume.

2) The fresh air window with filler can pre-cool, humidify and purify the fresh air, which has a good effect on improving the indoor working environment, and the filler b does not spray water, it can play the role of a water barrier, which can save Flap, reduce costs.

3) The fresh air window is equipped with an axial flow fan, which can realize forced air supply.

4) Compact structure, low cost, convenient installation, low energy consumption, especially suitable for small and medium-sized enterprises.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The evaporative cooling fresh air window with louvers for forced air supply of the utility model has its relative position structure as shown in Figure 1, and adopts the structure of direct contact heat and moisture exchange equipment between water and filler.

An air inlet 2 and an air supply outlet 12 are respectively arranged on the opposite side walls of the unit casing, and louvers 1 are arranged outside the unit casing and at the air inlet 2, and filter screens 3, packing a9, The filler b10 and the axial flow fan 11, the upper part of the filler a9 is provided with a dripping nozzle 8 for downward spraying, the lower part of the filler a9 and the filler b10 is provided with a water collection tank 6, and a water filter 5 is arranged in the water collection tank 6, and the circulating water pump 4 passes through The pipeline communicates with the water collecting tank 6, the water filter 5, the low-pressure water supply pipe 7 and the dripping nozzle 8.

The filler a9, the filler b10, the low-pressure water supply pipe 7, the water collection tank 6, the circulating water pump 4, the water filter 5 and the drip nozzle 8 constitute the direct evaporative cooling section.

The filler adopts the structure of setting front and rear two fillers, the thickness of filler b is half of that of filler a, the front part of filler a9 is used as a direct evaporative cooling section, and the rear part of filler b10 is used as a water baffle.

The evaporative cooling fresh air window of the utility model adopts a direct evaporative cooling section, that is, a packing section, and uses a circulating water pump 4 to spray the water purified by the water filter 5 in the water collection tank 6 through a low-pressure water supply pipe 7 to spray the packing a9, and the water relies on The gravitational force flows downward to wet the filler a9, and forms a thin water film on its surface to exchange heat and moisture with the air, so as to achieve the purpose of cooling and humidifying.

Filler b10 does not spray water, and the water droplets carried in the air passing through filler a9 can form a water film on the surface of filler b10, which further enhances the efficiency of direct evaporative cooling; it can separate water droplets carried in the air to reduce being carried away by the treated air of water.

The filter screen 3 can purify the outdoor air, protect the packing section from dust, and improve the heat and mass exchange efficiency between the water film and the air.

The water in the water collecting tank 6 will be processed through the water filter 5 to prevent the water outlets of the circulating water pump 4 and the drip nozzle 8 from being blocked.

The axial flow fan 11 sends the processed air into the room through the air outlet 12 to cool down the indoor air.

The working process of the new windshield of the utility model:

The outdoor air enters through the louvers 1 and the air inlet 2, and after the dust is filtered by the filter 3, it passes through the direct evaporative cooling section - the direct dripping packing section, and the water flows down by gravity to wet the surface of the packing a9 and form a water film, which is treated The air passes through the filler a9 in the horizontal direction to exchange heat and moisture with it, and the air is cooled and humidified. The filler b10 in the rear part makes the water droplets carried in the treated air enter the filler, which can reduce the amount of water entrained in the air and improve the efficiency of evaporative cooling. Finally, the axial flow fan 11 sends the treated air into the room through the air outlet 12.
