[Operation and Effect of the Invention] The present invention according to the above-described content has the following operation and effects.

In the method for cooling an object to be cooled using dust collection and filtered air shown in FIG. 1, the outside air taken in by the blower at the top of the cooling tower is cooled in the heat exchanger and at the same time sprayed water is sprayed from the nozzle. Insects and dust are collected and filtered by the bath and water filter effect. Unlike a mesh filter and a fibrous filter, this water filter does not become clogged because it circulates, and is extremely efficient in terms of convenience and maintenance.

Further, by the air blow of the blower, the sprayed water is mixed in the cooling air in the form of mist as it is, is guided to the cooling chamber under the ventilation state through the duct, and is sprayed on the object to be cooled, which requires a large amount of small electric power. Since the air blown by the blower that generates a large amount of air comes into intimate contact with the sprayed water, part of the sprayed water that adheres to the object to be cooled becomes water vapor and evaporates. Heat is taken away from the equipment, energy consumption is saved, the cooling capacity is increased, and the water consumption is small, without enormous equipment costs and running costs.

Further, when it is desired to change the temperature of the cooling air for cooling the object to be cooled in the cooling chamber in accordance with the room temperature, it is sufficient to change the opening degree of the valve body for controlling the water amount of the spray water of the cooling tower. Therefore, it is possible to make a very simple method by disabling huge equipment cost.

Further, in the embodiment shown in FIG. 2, a large amount of objects to be cooled can be dried quickly and efficiently with energy saving, which is extremely convenient.
