Principle of snow prevention

It shows the principle of snow protection for the IKP louver.

The principle of snow prevention involves installing snow-deflecting blades on the front of the IKP louver, raising the snow prevention wrap height, and preventing snow from blowing in from the front. The height of the large hood is diversified by the shape of the blades. Photo 4 shows the appearance of the IKP louver with snow-deflecting blades attached. Photo 5 depicts the situation during snowfall, where snow naturally falls off once it accumulates to a certain extent. Due to the angle of the photograph being from below, the front appears to be in a closed state because of the snow accumulation; however, in reality, it is in the situation shown in Figure 4, and the intake is hardly hindered. Additionally, in cases where a large amount of air is drawn in by fans or similar devices, the snow carried by the suction airflow collides with the IKP louver, causing the snow crystals to break apart and appear as diamond dust of less than 1 mm, which is then brought inside. As shown in Photo 5 and Figure 4, the intrusion of blown snow was effectively blocked. The snow carried in diamond dust form by the intake airflow came into contact with the rear filter and turned into water. By installing a water collection bucket between the rear filter of the IKP louver, the dead milk from the snow itself was effectively prevented.
