Therefore, the present invention uses all or part of the ventilator attached according to Article 28-2 of the revised Building Standard Law, is efficient, has a simple structure, has a remarkable cooling effect, and is also maintenance-friendly. It is an object of the present invention to provide a cooling device that can be easily installed at a low price in a new building as well as under a floor or a ceiling of a used or existing building.

In order to achieve the above-mentioned problems, the present invention solves the problems by adopting the inventions described in the claims. That is, a cooling device attached to a house where a ventilation device with a blower fan is provided in a part of the house,
1) A group of thin tubules made of a large number of good thermal conductors are provided so as to be able to come into contact with the water surface in the water tank through a pair of opposite side walls in a flat water tank. A sheet or tape cloth for sucking water by a capillary phenomenon made of a kind of synthetic resin sponge having a knitted fabric and a nonwoven fabric open cell is wound, and 2) a lid is provided on the upper surface of the water tank. Has a water tank exhaust port and a water tank air intake port that removes humid air generated in the water tank outside the house, and this water tank exhaust port can communicate with an exhaust port equipped with a ventilation device exhaust fan installed in the house And the water tank intake port is provided so as to be able to communicate with the air intake port that opens into the house. 3) The air intake side of the large number of air blow tube groups collectively includes the air intake port that opens into the house.

The blast tube group is an invention to which a requirement is added, characterized in that the blast tube group is composed of two groups, a group of water surface portions in the water tank and a position where the water surface part is completely submerged.
In addition, the configuration in which both ends of each blown tubule are integrated is a configuration in which a header adjacent to the water tank is interposed.
In addition, a requirement is added that a heat conduction plate having a diameter or a radial direction is formed integrally with each of the blower thin tubes inside each of the blower thin tubes.
In some cases, at least a portion below the water surface of the water tank is covered with a heat insulating material.

In the invention described in the above claims, when the indoor air temperature is comfortable, the water in the water tank is drained. Thus, the cooling fan is stopped and used as a normal ventilation device.
In this case, the indoor air once passes through the empty water tank and is exhausted outdoors.
Next, when using a cooling device, water is supplied to the water tank, and water is filled to such an extent that a portion of the air thin tube around which the sheet or tape cloth is wound reaches the water surface.
Thus, this water evaporates by wetting the sheet or tape wound around each air capillary tube by capillary action, and when the blower fans of both the ventilation device and the cooling device are operated, each of the ventilation capillary tubes is caused by the latent heat of vaporization. And cool the water in the aquarium.

The evaporated humid air is exhausted together with the dirty air in the room by the exhaust fan of the ventilator.
Therefore, since air is always supplied from the room to the air section in the water tank, the water vapor is not saturated, the evaporation continues to be accelerated, the group of tubules in the water tank and the water temperature are reduced by the latent heat of vaporization, Usually lower than temperature.
On the other hand, the air in the room is also sucked in from the air intake of the cooling device, passes through the air thin tube group, is cooled therein, is discharged into the room as cool air from the discharge port, and cools the room.
If air conditioning is temporarily unnecessary due to the weather conditions of the day, the ventilation device will function normally if only the cooling device fan is stopped.
The exhaust fan of the ventilator is provided on the exhaust side of the water tank so that the water in the tank has a slightly negative pressure, which promotes the evaporation of water and the cooling effect.
During the period where cooling is required, it is not necessary to drain water from the water tank when cooling is rarely required.

In the invention according to claim 2, the air tube group is composed of two groups of positions where the water surface portion in the aquarium and the water surface portion are completely submerged. Through the contact conduction of the cooled water in these tubes, the water temperature in the aquarium is lower than the ventilation air flow above it, effectively exchanging heat with the air flowing inside the submerged blast tube count, The heat exchange area of the blast thin tube group is increased, and the heat exchange efficiency is increased.

In the invention according to claim 3, since both end portions of each blower thin tube are gathered together by a header adjacent to the water tank, the structure is simplified, and on the discharge side, condensed water can be separated by this header, Prevent carryover of condensed water.
In the invention according to claim 4, since the inside of each blown tubule is formed with a diameter or radial heat conduction plate integrally with each of the blown tubules, The heat is also conducted to the surface of the blower thin tube group through the inner peripheral surface of the blower thin tube and the heat conduction plate, and the air is efficiently cooled.

In the invention according to claim 5, since at least a portion below the water surface of the water tank is covered with a heat insulating material, the water temperature in the water tank is kept particularly low, and the cool air is discharged from the discharge port accordingly.
However, when this water tank is installed on the ceiling, the ceiling is cooled by that amount without covering with the heat insulating material, and the cooling effect is assisted.
