る。2. Description of the Related Art Conventionally, as an underground structure of this type, there is one disclosed in Japanese Patent Publication No. 64-11788. In this underground structure, a cylindrical earth retaining wall is formed in the ground, an annular air supply vertical hole that forms a space for outside air suction to the ground is formed inside the earth retaining wall, and there are many rooms and passages inside. The circular main body of the floor and the atrium (courtyard space) are sequentially formed toward the center of the retaining wall. That is, an atrium is formed on the inner peripheral side of the annular main body, and an air supply vertical hole is formed on the outer peripheral side of the annular main body with the soil retaining wall. The annular main body has an opening that communicates with the vertical air supply hole and the atrium, and the top surface of the atrium communicates with the outside air. With this configuration, the temperature rise in the atrium portion due to solar radiation causes a pressure difference due to the temperature difference between the air supply vertical hole portion and the atrium portion, causing an updraft in the atrium, thereby supplying the outside air. The air is taken into the room or passage from the vertical hole, and then exhausted from there through the atrium.

いう欠点がある。However, since the ventilation in the above-mentioned conventional underground structure is carried out by utilizing the rise in the air temperature due to the solar radiation, if the presence or absence of natural wind is not taken into consideration, the variation in the amount of solar radiation will occur. The amount of outside air flowing through the living room fluctuates, and when there is no solar radiation, the outside air does not flow.

An air supply vertical hole is formed, and an opening for communicating the atrium side and the air supply vertical hole side is formed in the main body, and the pressure difference caused by the difference between the temperature in the air supply vertical hole and the temperature in the atrium is used. In the underground structure in which the main body is ventilated through the opening, the atrium is covered with a roof having an exhaust port, and the temperature in the atrium is raised above the temperature in the air supply vertical hole. It is characterized by having a heat supply device.

はないので、安定した換気を行うことができる。The atrium 7 is covered with a transparent daylighting roof 25 connected to the roof of the main body 9. An exhaust tower 27 having a heat exchange coil 29, which is an example of a heat supply device, is provided upright in the center of the daylighting roof 25. The heat exchange coil 29 is supplied with hot water of about 60 ° C. which is warmed by the waste heat of the fuel cell.
The temperature inside the exhaust tower 27 is higher than the temperature inside the air supply vertical hole,
For example, the temperature is raised to about 45 ° C. In this way, the temperature of the air is raised above the atrium 7 and a temperature difference is generated between the air supply vertical hole 10 and the air supply vertical hole 10 and the atrium 7.
A pressure difference is generated between the atrium 7 and the ascending airflow in the atrium 7, and the outside air is introduced from the air supply vertical hole 10 into the ceiling 25 and the living room 1.
1, to the atrium 7, and then to the exhaust tower 27 (this air flow is indicated by the arrow in FIG. 1). At this time, since the waste heat of the fuel cell does not fluctuate much like the amount of solar radiation, the inside of the exhaust tower 27 can be maintained at a substantially constant temperature. Needless to say, solar radiation also contributes to the temperature rise in the atrium, but since it is not a method that depends only on solar radiation, stable ventilation can be performed.

塔２７へと空気が流れ、居室１１内が換気される。In addition to the effect of raising the temperature by the heat exchange coil 29, when the indoor space is cooled and warm air is discharged from the outdoor unit 23 into the atrium 7, the temperature inside the atrium further rises. Therefore, even in the summer when the temperature of the outside air is high and natural ventilation is difficult to perform, the temperature of the air in the air supply vertical hole 10 and the temperature in the atrium 7 are combined with the cooling effect of the underground heat in the air supply vertical hole. Since it can be opened, the air flows from the air supply vertical hole portion 10 to the atrium 7 and further to the exhaust tower 27, and the inside of the living room 11 is ventilated.

上好ましいものである。According to the above embodiment, in each floor, air flows from the air supply vertical hole 10 to the atrium 7 and then to the exhaust tower 27, and even if a fire occurs in a living room on a certain floor, There is an advantage that the smoke does not easily enter the living room on the other floor. Further, even if a fire occurs in the atrium 7, the temperature in the atrium 7 rises, so that the air further flows from the air supply vertical hole 10 to the atrium 7 side.
Smoke in the atrium 7 does not easily enter the living room 11, which is preferable for safety.

く換気できる。As is apparent from the above, in the underground structure of the present invention, the atrium is covered with a roof having an exhaust port, and a heat supply device for raising the temperature in the atrium is provided near the atrium. Therefore, the temperature inside the atrium can be kept higher than the temperature in the air supply vertical hole at all times, and the outside air always flows from the air vertical hole to the atrium. Moreover, since the temperature rise by the heat supply device can be controlled so that the temperature difference between the air supply vertical hole side and the atrium side does not fluctuate much, a stable amount of outside air can be introduced into the living room. Also,
Since waste heat or solar heat can be used as a heat source of the heat supply device, ventilation can be performed without consuming extra energy.

すことができる。Further, if the outdoor unit for cooling is used as a heat supply device so that the warm air in the room is discharged to the atrium side, the temperature inside the atrium can be further raised, so that the outside air temperature is low. Even in the summer when the temperature is much higher than the middle temperature and ventilation is difficult, the temperature difference between the air supply vertical hole and the atrium can be generated, and the air can flow from the air supply vertical hole to the atrium.
