Description

Description: TECHNICAL FIELD The present invention relates to a building having an atrium and capable of heating and cooling using natural energy.

[Conventional technology]

2. Description of the Related Art In recent years, a large number of so-called atriums having a transparent roof made of glass on the upper part of an atrium space mainly in an office building have been adopted.

This atrium secures a bright atrium space in the building by natural light, and this space provides people working in the office with amenities (comfort).

[Problems to be solved by the invention]

However, the atrium only played a role as a space, and the value of use had always been to create a relaxed atmosphere in the building due to such a space.

SUMMARY OF THE INVENTION An object of the present invention is to solve the disadvantages of the conventional example and to provide a building using natural energy that can realize energy saving while providing amenity by positively using an atrium as a source of natural energy. It is in.

Means for Solving the Problems According to the present invention, in order to achieve the above object, in a building having an atrium, a solar cell is provided on a roof of an atrium, and an exhaust driven by the battery is provided on the roof and a suitable place. The gist is that a fan is provided, the underfloor of the living part facing the atrium is formed so as to communicate with the atrium, and a pit that communicates with this atrium and also communicates with the outside air is provided under the atrium. .

[Action]

According to the present invention, in winter, outside air is taken into the pit through the outside air intake pipe during the daytime, and the outside air exits the pit to the atrium and is warmed by solar radiation. The exhaust fan is driven by using the solar cell as a drive source, and the warmed air is sent to the ventilation space under the floor of the living part facing the atrium, and heat is stored on the floor to perform floor heating.

In summer, the power generated by the solar cell is stored in a storage battery, and the exhaust fan is driven at night to exhaust air from the roof of the atrium. In this way, the outside air is taken into the pit while being cooled down in the ground through the outside air intake pipe, and the cold air is stored in the pit and then goes out to the atrium, and the living room facing the atrium is acted upon by another exhaust fan. It enters the ventilation space under the floor of the part and cools under the floor.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a longitudinal sectional front view showing an embodiment of a building utilizing natural energy according to the present invention. A building 1 such as an office building is provided with a lighting roof 2a made of glass or other equal members at the upper part of a stairwell 2b. Atrium 2.

In the present invention, a solar cell 3 and an exhaust fan 4 driven by the cell 3 are provided on a daylighting roof 2a of the atrium 2. A storage battery 5 composed of a capacitor is connected to the solar cell 3, and an exhaust fan 4 composed of an AC motor is connected to the solar cell 3 and the storage battery 5 via an orthogonal converter 6 such as an inverter.

A ventilation space 9 communicating with the atrium 2 is formed below the floor of the dwelling part 7 facing the atrium 2 by an inverted beam 8 with a beam turned upside down, and further, the ventilation space 9 and the ventilation in the ceiling are formed between partition walls and the like. A vertical duct 11 communicating with the space 10 is formed.

The ventilation space 10 in the ceiling was connected to the atrium 2 via the exhaust fan 12.

This exhaust fan 12 is also driven by the solar cell 3 like the exhaust fan 4.

Further, a pit 15 communicating with the atrium 2 at the outlet 13 is provided below the atrium 2, and a cool air tube is used, and an outside air intake pipe 14 which passes through the ground and opens to the ground is provided in the pit 15.

 Next, usage and operation will be described.

First, in winter, as shown in FIG. 2, the exhaust fans 4, 12 are driven in the daytime using the solar cell 3 as a drive source.

The air in the atrium 2 is exhausted from the roof 2a by the exhaust fan 4, and the outside air is taken into the pit 15 via the outside air intake pipe 14 by that amount. The outside air taken into the pit 15 is slightly warmed while passing through the ground by the outside air intake pipe 14 and accumulates in the pit 15. Then, the outside air enters the atrium 2 through the outlet 13 from the pit 15 and is heated by the solar radiation from the daylighting roof 2a.

In other words, the atrium 2 exerts a greenhouse effect. By driving the exhaust fan 12, a circulation air path of the atrium 2 → the ventilation space 9 → the vertical duct 11 → the ventilation space 10 → the atrium 2 is formed. The air warmed in 2 is stored on the floor in the ventilation space 9 below the floor of the living part facing the atrium 2 to perform floor heating.

In addition, the operation of the exhaust fan 4 may be stopped as necessary, and the filled warm air may be stored in the atrium 2.

In the summer, the power generated by the solar cell 3 is stored in the storage battery 5 in the daytime, and the exhaust fans 4, 12 are driven at night using the storage battery 5 as a power source as shown in FIG.

The air is exhausted from the atrium roof 2a by the exhaust fan 4, and the outside air is taken into the bit 15 while being cooled in the ground through the outside air intake pipe 14 by that amount. This cold air is in the pit
After being stored in the air outlet 15, the air enters the atrium 2 through the outlet 13, and further enters the ventilation space 9 under the floor of the living room facing the atrium 2 by the action of the exhaust fan 12, and is stored under the floor.

After the cold storage, the air passes through the vertical duct 11, circulates in the ventilation space 10 in the ceiling, and is exhausted to the atrium 2 by the exhaust fan 12.

〔The invention's effect〕

As described above, the building using renewable energy of the present invention can be used not only as a place for simply providing amenities as in the past, but also as a source of natural renewable energy by the sun in a building with an atrium. By doing so, heating and cooling can be used and energy saving can be realized.

In addition, the exhaust fan uses a solar cell as a driving source, does not require running costs, and requires a small amount of electric power unlike an active system using mechanical power, and requires a small number of solar cells.
