Building circulation system using curtain wall as ventilator

Abstract

A ventilation system for a high-rise building is disclosed. The ventilation system comprises an external curtain wall 200 disposed to surround the building. The external curtain wall is spaced apart outwardly from the outer wall 22 by a certain distance. An external air suction port 210 is disposed in lower story portion of the external curtain wall 200. External air is introduced through the external air suction port 210. An air stream exhaust port is provided in a space between the rooftop of the building and the upper end of the external curtain wall 200 extended horizontally to cover part of the rooftop of the building. The air stream exhaust port 220 has a pivot slit capable of being closed and opened. The external curtain wall 200 does not surround the entire four sides of the building, but part of the building sides is open without installing the external curtain wall 200 such that external air is directly introduced into the internal space of the building through a window 11 provided in the respective stories of the building, thereby using the external curtain wall as an exhausting space.

Description

TECHNICAL FIELD[0001]The present invention relates to a ventilation system for a high-rise building for blocking radiation heat of the sun from being transferred to the internal space and simultaneously for utilizing an external curtain wall as an exhausting space, and more particularly to a ventilation system for a high-rise building, in which an external curtain wall 200 is disposed to surround the building, the external curtain wall is spaced apart outwardly from the outer wall 22 by a certain distance, an external air suction port 210 is disposed in lower story portion of the external curtain wall 200, external air is introduced through the external air suction port 210, an air stream exhaust port is provided in a space between the rooftop of the building and the upper end of the external curtain wall 200 extended horizontally to cover part of the rooftop of the building, the air stream exhaust port 220 has a pivot slit capable of being closed and opened, the external curtain wa...

AI Technical Summary

Benefits of technology

[0005]The first object of the present invention is to provide a ventilation system, in which natural ventilation mode and forcible ventilation mode are harmonized to minimize the maintenance cost of the ventilation system and enable to reduce operation noises of the ventilation system and discomforts to the residents.

[0006]The second object of the invention is to provide a ventilation system, in which the increase in the internal temperature by radiation heat of the sun can be prevented.

[0007]The third object of the invention is to provide a ventilation system, in which radiation heat of the sun can be effectively discharged by means of the chimney effect.

[0008]The fourth object of the invention is to provide a ventilation system, in which radiation heat of the sun can be blocked and the right of a view can be secured.

[0009]The fifth object of the invention is to provide a ventilation system, in which a separate vertical duct for exhaustion is not necessitated, thereby enabling to secure a maximum residential space.

[0010]The sixth object to of the invention is to provide a ventilation system, in which a fire can be prevented from being propagated into other stories, and the heating cost in winter can be saved by controlling so as not to generate the chimney effect in the winter season.Technical Solution

Problems solved by technology

These conventional ventilation systems do not meet the required capacity for the internal space of each story.

In addition, the system is complicated to increase the installation and maintenance cost, and to generate noises due to forcible ventilation, leading to discomfort to the residents.

Further, in case of a high-rise building (in particular, a recently popular residence-commercial combination building), the upper story portion thereof has a high internal temperature during the summer time due to radiation heat of the sun, thereby significantly increasing the operation cost of a cooling system.

In certain cases, a comfort internal environment cannot be obtained, even if the cooling system is operated with a maximum load.
