Problems solved by technology

[0005] In the technology described in Japanese Patent Laid-Open No. 2007-115459, the fuel cell is placed on the ground and outdoors. Therefore, the hydrogen in the exhaust gas is diluted by the atmosphere, and the fear of intrusion into the interior of the building is reduced. However, only hydrogen tanks are installed underground and cannot be effectively used. underground space
The technology described in Japanese Patent Laid-Open No. 7-48005 does not assume that fuel cells are arranged in underground spaces

no. 1 Embodiment approach

[0022] The ventilation system 100 of the first embodiment will be described. figure 1 It is a schematic diagram of the ventilation system 100.

[0023] like figure 1 In that case, the ventilation system 100 includes a building 110, which has space 111 inside; underground apparatus 120, which is disposed underground, and has underground space 121 inside; communication passage 130, which makes space 111 and The underground space 121 communicates; and the vent hole 140 that connects the upper ground and underground space 121 of the building 110.

[0024] The use of buildings 110 is not particularly limited, and can be a house or a office. The building 110 has space 111 internally. Preferred space 111 is a living space that people can live. Further, in the case where the building 110 has a basement, the underground device 120 can also be disposed at a position that is more underground than the basement.

[0025] Underground device 120 has underground space 121 internally. The use of t...

no. 2 Embodiment approach

[0037] The ventilation system 200 of the second embodiment will be described. figure 2 A schematic diagram showing the ventilation system 200. The venting system 100 and the vent system 200 differ in the lifting machine which is subjected to the inside of the communication passage 230, which is the same as those other than the structure. Therefore, hereinafter, it is intended to be in connection with the communication passage 230.

[0038] For communication 230, the side wall 231 extends from the ceiling 121a to the ground 121b of the underground space 121, and there is an elevator that can be used to move the article up and down in the inner passage 230.

[0039] Further, the communication passage 230 removes a portion of the side wall 231 on the side 121b side, including: a first opening portion 232 that is opened at a vertical direction formed by the side wall 231 and the ground 121b ( figure 2 Denal line portion). The first opening portion 232 has a door (not shown) capable of...

no. 3 Embodiment approach

[0042] The ventilation system 300 of the third embodiment will be described. image 3 A schematic diagram showing the ventilation system 300. The different point of the ventilation system 200 and the vent system 300 is to provide the eave portion 333 in the communication passage 330, except that the structure is the same. Therefore, the following is focused on the communication 330.

[0043] The sidewall 331 of the communication path 330 has an eave portion 333 that protrudes from the side wall 331 toward the outer side of the communication passage 330. Further, the orientation portion 333 is disposed on the upper side of the first opening portion 332 on the side of the underground space 121 of the communication passage 330, and the secondary passage 330 is disposed on the second of the exhaust port 122a to the vent hole 140 from the fuel cell unit 122. When the opening portion 141 is connected, the sidewall 333 is disposed on the side wall 331 on the side of the exhaust port 122a,...

Abstract

A ventilation system includes a building having a space inside, a subterranean facility arranged in a basement of the building and having a subterranean space inside, a communication passage establishing communication between the space and the subterranean space, and a ventilation hole establishing communication between an earth outside the building and the subterranean space is provided. A fuel cell unit having an exhaust port is arranged in the subterranean space. The communication passage has a lateral wall protruding downward from a ceiling of the subterranean space. The lateral wall is arranged on the exhaust port side when the communication passage is arranged on a straight line linking the exhaust port and a second opening portion of the ventilation hole on the subterranean space side. The lateral wall is arranged on the straight line side when the communication passage is arranged at a position spaced apart from the straight line.

Description

Technical field [0001] This application relates to a ventilation system. Background technique [0002] There is a technique that has an infrastructure equipped with a building, improves safety, and convenience. For example, Japanese Laid-Open 2007-115459 discloses a private power generation system with a fuel cell device outside of the house. Japan's special opening 7-48005 discloses a logistics system, which is formed to communicate between the households and the underground space, and pass through the communication between the household and the underground space. Japanese Laid-Open 2008-151482 discloses a ventilation system that connects the buildings in the atmospheric environment that have a negative impact on people, and the region of the atmospheric environment is connected via connectivity passages, etc., and conducts ventilation of the building. [0003] On the other hand, in recent years, urban ideas for the underground areas and in situ are safe and easily moved in the ...
