Description

Building Circulation System using Stair Hall or Elevator Shaft}

The present invention is a multi-storey building including a household head space 100, a common corridor 200, a stair room 300, and an elevator shaft 400, the household head space (using a staircase room 300 or an elevator shaft 400) The present invention relates to a system for ventilating 100, comprising a first vent opening (10) and a second vent opening (20) communicating a household main space (100) with a staircase room (300) or an elevator shaft (400), and a second vent opening ( 20) is characterized in that the blower 22 is installed.

The conventional multi-storey building connects the air passages provided in each floor to a single ventilation chamber, and operates a blower fan to perform forced ventilation to release air from the air collected in the ventilation chamber to the outside, or is provided on each floor. Although the individual ventilation system is applied to each floor to directly discharge the air in the room to the outside air, all of these conventional ventilation systems not only meet the ventilation required in the interior of each floor, Since the device is complicated, installation and operation costs increase, and there is a problem of causing noise and uncomfortable body caused by forced ventilation.

In addition, the upper floors of multi-storey buildings (especially high-rise buildings, such as modern multi-purpose buildings), have a high temperature in the summer due to the sun's radiant heat. There is also a problem that can not create a comfortable indoor environment.

In order to drastically improve the ventilation of the multi-storey building, it is necessary to prepare a separate vertical passage and to induce a smooth air flow between the living space and the vertical passage. The separate provision is a problem that the residents are inconvenient, even if the cost is aside.

Therefore, it is required to introduce a new ventilation system that can maximize the ventilation effect at the minimum cost by utilizing the existing building structure to the maximum.

The object of the present invention created to solve the above problems is as follows.

First, it is an object of the present invention to maximize the ventilation effect by maximizing the structure of the existing building and providing an unnecessary ventilation system without a separate duct facility.

Secondly, it is another object of the present invention to provide a means for effectively exhausting the heat of the room to the outside by effectively ventilating each floor of a multi-story building.

The configuration of the present invention created to achieve the above object is as follows.

The present invention is a multi-storey building including a household head space 100, a common corridor 200, a staircase room 300, and an elevator shaft 400, which divides the household head space 100 and the shared corridor 200. A first vent hole 10 provided on the vertical wall surface; A second vent hole 20 provided on a vertical wall surface partitioning the common corridor 200 and the staircase room 300 or the common corridor 200 and the elevator shaft 400; A first fire damper (11) installed in the first vent (10) and provided with an openable / closed slit; A second fire damper (21) installed at the common corridor (200) side of the second vent (20) and having a slit to open and close; And, the stair room 300 or the elevator shaft 400 side of the second vent 20, the indoor air passing through the second fire damper 21, the stair room 300 or the elevator shaft 400 Blower 22 to be discharged to); is configured to include, the staircase room 300 or the elevator shaft 400 is connected from the lower floor to the upper floor of the multi-storey building, the staircase room 300 or the elevator shaft 400 It is characterized in that the upper portion of the air flow outlet 30 in communication with the outside;

Technical effects according to the present invention of the above configuration is as follows.

First, it is possible to provide a ventilation system that takes full advantage of the structure of the existing building.

In other words, instead of creating a separate vertical passage, it is a system that utilizes stairs or elevator shafts provided in existing buildings as vertical passages and does not require the installation of a separate duct. In addition, even in the case of renovation of existing buildings, the construction period can be minimized and the air can be shortened to minimize the inconvenience of residents due to the renovation of the building.

Second, it is possible to effectively ventilate each floor of the multi-storey building through the upper floor and the lower floor of the staircase or elevator shaft and quickly discharge the heat of the interior to the outside.

In other words, in the household space, the heat generated from the residents themselves, the heat generated from electrical and electronic products such as computers, refrigerators, TVs, or various lighting appliances, and the heat generated from the heat generated from the main kitchen spaces, solar, The temperature of the room is increased by the radiant heat, etc., the heat must be discharged quickly to prevent the increase of the room temperature and reduce the cooling cost.

In the present invention, the heat of the room discharged to the staircase or the elevator shaft through the household main space and the common corridor may be discharged to the outside through the airflow outlet of the upper part of the staircase or the elevator shaft, or through the lamp communication port of the lower floor of the staircase or the elevator shaft. It may be discharged to the outside.

By implementing an effective ventilation system that takes full advantage of this natural ventilation method, the indoor heat can be quickly discharged to the outside and the cost of indoor cooling can be minimized.The ventilation volume of the head of household is 11 times per hour (11 times the volume of head of household space per hour). When the amount of air is discharged to the outside), the main flow is maintained in the household main space maintaining an average speed of 0.2 to 0.5 ㎧. If a periodic flow of such a speed is formed, there is no need to operate a separate cooling facility up to an outdoor temperature of 27 ° C.

In Korea, the annual time exceeding 27 ℃ is roughly 450 hours, which is concentrated in summer. Therefore, in the case of applying the present invention, if the cooling facility is operated at a minimum within 450 hours, the cooling cost is drastically reduced.

In the case of the ventilation system that removes the odor of the conventional toilet or kitchen, the odor is induced to one narrow vertical duct through the exhaust duct installed in the bathroom or kitchen of each floor of the building, and the vertical duct is discharged to the outside. It is open to communicate with outside air and the lower part is blocked. Therefore, only a small amount of odor can be removed, can not use the downdraft, indoor heat discharge through ventilation is limited in that it is essentially different from the configuration and effect of the present invention.

Third, the ventilation of the common corridor along with the head of household is also effective.

That is, the present invention does not install a separate duct but uses an existing staircase or an elevator shaft as a vertical passage for ventilation, and a separate duct is also used in the process of discharging the heat of a household head of each floor to a staircase or an elevator shaft. Instead of being used, a common corridor is used as the hot air outlet.

Therefore, the ventilation of the common corridor on each floor of the building naturally occurs in the course of the ventilation of the main building spaces on each floor of the building, thereby effectively performing the ventilation of the entire building.

In the conventional ventilation system to remove odors in a bathroom or kitchen of a general building, it is possible to remove odors only in a limited space, and it is not possible to expect ventilation of the entire household space on each floor of the building. As the flow is generated, the structure and effect of the present invention is essentially different from the present invention in that the ventilation of the common corridor cannot be simultaneously performed.

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