Description

  The present invention relates to a building capable of natural ventilation.

  In recent years, with the development of air conditioning equipment, air conditioning equipment is used for air conditioning. Therefore, in a building such as a house, in order to enhance the air conditioning effect, to prevent indoor and outdoor air from entering and exiting, to prevent indoor heat from leaking to the outside, and to reduce energy loss in the air conditioning inside the building Highly airtight and highly heat-insulated buildings with high indoor airtightness and heat insulation are used.

In such a highly airtight and highly insulated building, the indoor and outdoor air is blocked from entering and exiting, so the building must be well ventilated.
Therefore, in order to ventilate a highly airtight and highly insulated building, a central ventilation device is used that collectively ventilates a plurality of partitioned spaces such as a living room in the building (see, for example, Patent Document 1).
However, when such a ventilator is used, it is costly to install the ventilator and consumes a lot of energy. Therefore, in summer, it is desired to perform natural ventilation without using the ventilator.
By the way, the conventional natural ventilation has been performed by opening the windows and doors of each room to introduce outside air into the building and replacing it with the air inside the building.

Japanese Patent Laid-Open No. 11-344253

  However, simply opening the windows and doors of each room has a problem that warm air accumulates near the ceiling of each room. In addition, it is difficult to increase ventilation efficiency because windows and doors are not always provided facing the direction in which the wind blows.

  The objective of this invention is providing the building which can perform natural ventilation efficiently.

Therefore, the present invention intends to achieve the object by adopting the following configuration.
The invention described in claim 1 is a building 1 including a building main body 3 and a roof 4 provided on the upper portion of the building main body 3, and the building main body 3 has a flow for taking outside air into the room. An entrance 270A, 300A, a passage through which the outside air taken in from the inflow ports 270A, 300A passes through a plurality of rooms, and a part of the ceiling in the passage protrudes upward from the ceiling of the other part of the passage. A ventilation ceiling 255 formed at a high position, and an exhaust port 252 that discharges air that has flowed in from the inlets 270A and 300A and accumulated in the ventilation ceiling 255. The inlets 270A and 300A A room 25 having a ventilation ceiling 255 that faces the direction in which the wind blows most frequently in a given season is located in the shed 5 formed between the building body 3 and the roof 4.

In addition, although the main dining room 15 and the kitchen 17 provided with the ground windows 150B and 170B are ventilated by the upward flow, other rooms in the outside air passage may be ventilated by the upward flow. The upward flow makes it possible to ventilate the entire other room.
In addition, vertical axis windows 150A, 170A, etc., which are the inlets of outside air, are provided on the east wall where the wind blows most in summer, but on the wall facing the direction in which the wind blows most in autumn or spring, and in some cases winter. It may be attached.

(The invention's effect)
According to the first reference example of the present invention, since the building is provided with an inlet and an exhaust port for taking in the outside air, the outside air passes through the building, and natural ventilation is performed inside the building without using a ventilation device. Can save energy. In addition, since a ventilation ceiling with a ceiling position higher than the ceiling of other parts is formed in a part of the ceiling in the passage through which the outside air passes, air that accumulates in the vicinity of the ventilation ceiling is exhausted from the exhaust port. can do. Therefore, the air flow inside the building is improved and natural ventilation can be performed more efficiently. Moreover, warm air does not accumulate in the living space below the ventilation ceiling, and the living space can be made more comfortable.
Furthermore, since the inflow port is provided in a predetermined season, for example, the direction in which the wind blows most frequently in summer, the outside air can be efficiently taken into the building.
In addition, since the outside air passage is formed through a plurality of rooms, even if there is a room where it is difficult to take in outside air, it is possible to ventilate the room by forming the outside air passage through the room. .

According to the second reference example of the present invention, the vertical axis rotation window is provided at the inlet, and the outside air is more efficiently taken into the building by adjusting the opening angle of the rotation window according to the wind direction. Can do.
According to the third reference example of the present invention, since the inflow port is formed in the lower part of the outer wall of the room, the outside air can be taken in from the lower side of the room and discharged from the vicinity of the ceiling. Therefore, the whole room can be ventilated by the upward flow.

According to the fourth reference example of the present invention, if the ventilation ceiling is formed at a position higher than the height of the occupant, the occupant does not feel the warm air collected on the ventilation ceiling. Can be made comfortable.
According to the fifth reference example of the present invention, the support strength of the ventilation ceiling can be increased by providing the beam on the wall that supports the ventilation ceiling. In addition, when the height of the ceiling formed at a position lower than the ventilation ceiling of the room provided with the ventilation ceiling is lowered and this room is used as a warehouse, the lower part of the ceiling is not handled as a living room, Not included in the floor area of the building. However, since the ceiling for ventilation is high, the lower part of the ceiling for ventilation is handled as a normal living room and may be included in the floor area. In contrast, in the present application, a beam is provided below the ventilation ceiling, and the ceiling height is calculated based on the height of the beam. Therefore, the floor area of the building is also below the ventilation ceiling. Will not be counted. Therefore, a building can be configured by making the best use of the determined volume ratio.
