Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to the air conditioning structure of a house, and in particular makes it possible to introduce cooling air into the house from under the floor and to systemize the ventilation route throughout the room. This relates to the air conditioning structure of houses.

<Prior art> Conventionally, for example, as in the Iranian cooling system shown in FIG. Ideas for cooling air using the earth existed, such as the cool tube method, in which the air taken in from the ground is cooled and humidified by passing through the ventilation passage 1, and then taken out from the cold air intake port 4, and this cooled air is used for cooling buildings, etc. .

<Problems to be solved by the invention> However, in the above-mentioned cool tube method, etc., burying the tube is a special work, and it is not compatible with conventional construction methods for houses, and furthermore, these techniques simply introduce cooled outside air. However, the issue of how to efficiently systemize the entire room remained unresolved.

The present invention relates to a completely new technique developed in view of these conventional problems.

<Means for Solving the Problems> The present invention provides an outside air intake in the side wall under the floor of a building, an intake damper in the outside air intake, and a cooling air duct or supply in the building that communicates with the underfloor. This is an air conditioning structure for a house that is constructed with vents.

<Function> As described above, in the present invention, an outside air intake is provided under the floor, and a cool air duct or air supply opening that can directly take in the air under the floor into the house is provided in the building. It is possible to directly introduce air into the house, especially on each floor, to distribute the air supply.

<Example> To specifically explain an example of the air conditioning structure according to the present invention with reference to the drawings, in FIGS. A peripheral wall 5a that is under the floor and also serves as the foundation of the outer periphery of the building, and a floor surface 5b that has soil moisture countermeasures such as concrete or moisture-proof sheet + sand paving.
In addition, an outside air intake port 6 is provided in the peripheral wall 5a on the north side, which is not exposed to sunlight. An intake damper 7 that can open and close the outside air intake 6 is provided along the inside of the outside air intake 6. Furthermore, under the floor 5, there is a
As is clear from Figure (A), there is a sand embankment 8 near the outside air intake port 60 to prevent sand from entering under the floor, and several ms inward to lengthen the ventilation route of the under floor 5. Partition slope 9 has been erected.

It is also possible to use the foundation inside the building for this partition plate. 10 is a cool air duct for the second floor installed along the vertical wall surface of the building, the lower end of which is open to the underfloor 5,
The upper end is open to the floor 11 of the second floor, and an air supply fan 12 and an air supply rod damper 13 are provided at the upper end. Reference numeral 14 denotes an air supply port bored in the floor surface 15 of the first floor so as to communicate with the underfloor 5, and an air supply fan 12 and an air supply rod damper 13 are provided inside the air supply port. Furthermore, exhaust ducts 17 and 18 having exhaust ports 16 are provided in the ceilings of the first and second floors of the building, respectively, and an exhaust fan 19 is installed in the middle of the ducts. Furthermore, the two types of air supply fan 12 and the exhaust fan 19 described above are configured to be operated by a timer switch 20 for the supply and exhaust fan, which can be operated in conjunction with each other or individually.

To explain the operation of the air conditioning structure according to the present invention, first, as shown in FIG. 2, in the middle seasons such as spring and autumn, and in the summer, the intake damper 7 of the outside air intake 6 is opened to draw outside air into the underfloor 5. , Cooled air is passed through the floor surface 5b under the floor 5 (e.g. outside air?! 30°C).
Cooling air at 24-25°C) is supplied by the air supply fan 12.
By operating the exhaust fan 19 etc., the cool air duct 1
The air is taken into the room on the second or first floor from the air supply port 14 and circulated inside the room, and then exhausted from the exhaust port 16, thereby cooling the room on the second and first floors and refreshing the air.

Next, in the winter, as shown in Figure 3, the space under the floor 5 is sealed by closing the outside air intake 6 in the underfloor 5 with a damper 7, thereby making the underfloor space lower than the outside temperature by the action of geothermal heat. It is possible to maintain a high temperature (for example, 5 to 10 degrees Celsius even when the outside air is 0 degrees Celsius), and it is possible to obtain the effect of indirect radiant heating for the rooms on the first floor, thereby reducing the cold phenomenon in winter. can be prevented.

<Effects of the Invention> As described above, the spatial structure of the house according to the present invention has an outside air intake under the floor, so in summer, etc., the outside air taken in under the floor is cooled by passing through the underfloor. Furthermore, since the underfloor area is connected to each room of the building via ducts or air supply ports, the cooling air that has passed under the floor is sent directly to each room to cool each room, and also to cool each room. The air can be kept fresh all the time, and as a result, there is almost no need for air conditioning on summer days or during the middle of the summer, which allows natural air conditioning to be used and saves on electricity costs. By closing the outside air intake, the space under the floor can be kept higher than the outside temperature using geothermal heat to prevent it from getting cold, and the above-mentioned air circulation system such as under the floor, duct, air supply opening, fan, etc. By using this, you can automatically adjust the air conditioning in the room even if the windows are completely closed, and this allows for sufficient ventilation when sleeping or when you are away. Foundation.

It has the characteristics of preventing flooring materials from rotting due to moisture and making buildings last longer.
