Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation structure for a building in which a translucent body such as glass is provided on a window side in a room at predetermined intervals in a horizontal direction.

[0002]

2. Description of the Related Art The following is conventionally known as this type. A. First conventional example (Japanese Patent No. 2597395) There is a sash that is provided with double glass inside and outside between the upper and lower frames of a building opening, and the space between the glasses is an air chamber, and the air chamber and the outdoor are separated from each other. An open / close valve is provided on the communicating outer duct, an inner duct is provided for communicating between the air chamber and the room, an air conditioner is provided for communicating with the inner duct, and the air discharged from the air conditioner is guided to the air chamber before the building It is configured to release to.

B. Second conventional example (Japanese Patent Publication No. 62-48142)
(Japanese Patent Laid-Open Publication No. 2004-242242) A double glass window with a built-in blind is provided with a heat exchanger for exchanging heat between the exhaust air from the room and the introduced air from the outside, and after passing the exhaust air from the room through the glass window. It is configured to pass through the heat exchanger and be discharged.

[0004]

However, the above-mentioned conventional example has the following drawbacks. a. Disadvantages of the first conventional example By guiding the air-conditioned air that has been air-conditioned in the room to the air chamber, the contaminated air in the room is not directly sent to the air chamber and the inner surface of the glass is not contaminated. , The temperature difference between the temperature inside the air chamber and the temperature inside the room is reduced to improve the thermal characteristics of the room.
The outside air before air conditioning used for air conditioning is directly introduced into the air conditioner, and the air conditioning load on the outside air before this air conditioning cannot be reduced. In addition, for each floor, air-conditioned air is exhausted from the air chamber to the outside of the building, and each floor must be equipped with an atmospheric emission structure to prevent rainwater from entering and to the outside of the building. However, in the case of a multi-story building, there is a drawback in that a large number of atmospheric emission structures are required and the cost is high.

B. Disadvantages of Second Conventional Example Although heat is exchanged between the exhaust air from the room and the introduced air from the outside by a heat exchanger, the exhaust air from the room passes through the glass window and then the heat exchanger. However, since the amount of heat recovered from the air introduced from the outside is small, the air conditioning load on the outside air before air conditioning used for air conditioning cannot be sufficiently reduced. Further, similarly to the first conventional example, the air-conditioned air is discharged to the outside of the building through the heat exchanger for each floor.
There is a drawback in that a large number of atmospheric emission structures are required and the cost becomes high.

As described above, in any of the conventional examples, there is still room for improvement in reducing the air conditioning load on the outside air before air conditioning used for air conditioning. Also,
When applied to a multi-story building, there is a drawback that construction costs are high due to the atmospheric emission configuration.

The present invention has been made in view of such circumstances, and the invention according to claim 1 is to make it possible to satisfactorily reduce the air conditioning load on the outside air before air conditioning used for air conditioning. The invention according to claim 2 is intended to simplify the structure of releasing into the atmosphere and reduce the construction cost when applied to a multi-story building.
An object of the present invention is to prevent defective discharge of air-conditioned air due to the occurrence of dew condensation.

In addition, the invention according to claim 5 aims at simplifying the atmospheric emission structure and reducing the construction cost when applied to a multi-story building, and the invention according to claim 6 prevents the occurrence of dew condensation. It is an object of the present invention to prevent defective discharge of air-conditioned air due to the object, and an object of the invention according to claim 7 is to increase the degree of freedom in design and to effectively utilize the perimeter zone.
