Benefits of technology
The patent describes a ventilation system for a subway platform that helps to efficiently cool it down. This system aims to make the subway platform more comfortable and safe for passengers.
Problems solved by technology
Therefore, in the related art, it is impossible to form the flow of air capable of effectively discharging pollutants from the interior of a subway platform, that is, the flow of air exhausted through an exhaust port in a state including pollutants after air supplied through an air supply port circulates entirely inside the subway platform.
Various techniques have been proposed to solve this, but since it is necessary to change the position of an air supply port and / or an exhaust port or to add a separate air supply device, it is impossible to use an existing duct installed in a subway platform.
Therefore, in the related art, because air supplied through an air supply port is deflected in a direction to flow to an air supply duct, as described above, it is difficult to flow air for efficient discharge of pollutants.

case 1
[0047]In [Table 1], [CASE 1] to [CASE 3] are a case where the air guide 320 includes one reverse air guide 321, a case where the air guide 320 includes two reverse air guides 321, and a case where the air guide 320 includes two of the reverse air guides 321 and one forward air guide 323, respectively, in an embodiment, and [CASE 4] is a case according to the prior art.
[0048]Referring to [Table 1], it can be seen that in the case of the embodiment, ventilation is remarkably efficient compared to the case of the prior art.
[0049]In the ventilation system for the subway platform according to an embodiment, by supplying air toward the side of the subway platform at an angle with respect to a vertical surface by an air supply hood, the supplied air is exhausted by an exhaust hood with pollutants while circulating evenly along side and bottom surfaces of the subway platform. In particular, in the embodiment, while air is guided in a direction opposite to the direction in which air flows th...

A ventilation system for a subway platform includes: an air supply duct through which air supplied to the interior of a subway platform flows; an exhaust duct through which air supplied to the outside of the subway platform flows; a plurality of air supply hoods that supply air in the air supply duct to the interior of the subway platform and are arranged to be apart from each other in a direction in which air flows through the air supply duct; and a plurality of exhaust hoods that exhaust air from the subway platform together with pollutants in the subway platform to the exhaust duct and are arranged to be apart from each other in a direction in which air flows through the exhaust duct, wherein the air supply hood is arranged to be inclined downward at an angle toward one side of the subway platform to supply air.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to Korean Patent Application No. 10-2019-0151398, filed on Nov. 22, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.BACKGROUND1. Field[0002]One or more embodiments relate to a ventilation system for a subway platform.2. Description of the Related Art[0003]Because subway platforms are often installed underground, ventilation is required to discharge pollutants in the air inside the subway platform. Moreover, because the side of the subway platform is open for boarding or getting off the subway, a ceiling of the subway platform is provided with an air supply port for supplying air into the subway platform for ventilation and an exhaust port for exhausting air supplied to the interior of the subway platform together with pollutants to the outside of the subway platform.[0004]However, in general, the air supply port and the exhaust po...
