  • an external curtain wall 200 is disposed around three sides of a high-rise building, not all the four side thereof. That is, the external curtain wall 200 is not disposed in the remaining one side of the building.
  • the external curtain wall 200 is disposed in the eastern, western and southern side of the building where receive sunlight, not in the northern side thereof.
  • FIG. 3 two southern sides thereof can be installed with the external curtain wall 200, and two northern sides can be installed with no external curtain wall 200.
  • an external air suction port 210 Provided in the lower story portion of the external curtain wall 200 is an external air suction port 210 that can be closed and opened.
  • the upper end portion of the external curtain wall 200 is structured in such a way to be extended in horizontal direction and cover part of the rooftop of the building.
  • An air stream exhaust port 220 is provided between the end portion of the extended external curtain wall 200 and the rooftop of the building.
  • the air stream exhaust port 220 is formed of a damper that can be opened and closed.
  • a forcible exhaust port 230 is installed in parallel to the air stream exhaust port 220 and forms a separate exhausting space, as shown in FIG. 1.
  • the forcible exhaust port 230 is provided between the end portion of the extended external curtain wall 220 and the rooftop of the building, separately from the air stream exhaust port 220.
  • the air stream exhaust port 220 is in charge of natural ventilation, and the forcible exhaust port 230 performs forcible ventilation using an air blower 235, which induces an artificial upstream air.
  • the air blower 235 When the air blower 235 generates a forcible upstream air and exhausts the upstream air through the forcible exhaust port 230, it is desirable that the pivot slit is closed to block the air stream exhaust port 220. That is, in case where the air blower operates, if the air stream exhaust port 220 is open, the air near the air stream exhaust port 220 can flow back to the inside of the air stream exhaust portion 220, thereby degrading the effect of forcible exhaust.
  • the air blower 235 installed in the forcible exhaust port 230 may be set to automatically operate when the velocity of the upstream air being generated in the space between the external curtain wall 200 and the outer wall 22 of the high-rise building is decreased below a certain value.
  • the window 11 provided in the building side having the external curtain wall 200 is formed with a pivot in such a way that the upper side of the window 11 can be opened outwards, thereby enabling to discharge the internal thick air more efficiently.
  • the internal thick air which is discharged through the space between the external curtain wall 200 and the outer wall 22, ascends along the upstream air and then is discharged through the air stream exhaust port 220 or the forcible exhaust port 230 to the outside.
  • the air introduced through the window 11 is circulated in the internal space 33, then led into the space between the external curtain wall 22 and the outer wall 22, ascends by the upstream air, and is discharged back to the outside through the air stream exhaust port 220 or the forcible exhaust port 230.
  • the external curtain wall 200 includes a glass. As enlarged in FIG. 1, a solar heat shielding film 44 is attached to the inner face of the glass.
  • the solar heat shielding film 44 prevents radiation heat of the sun from reaching the internal space 33.
  • the temperature in the inner side of the external curtain wall 200, to which the solar heat shielding film 44 is attached, is increased.
  • the solar heat shielding film 44 blocks radiation heat of the sun from reaching the internal space 33. Simultaneously it induces the upstream air in the space between the external curtain wall 200 and the outer wall 22 so that the heated air in the inner side of the external curtain wall 200 can be prevented from being transferred to the internal space.
  • FIGS. 4 and 5 show a ventilation system according to another embodiment of the invention, in which a shielding glass 100 is further installed.
  • the shielding glass 100 is disposed in the space between the external curtain wall
  • the solar heat shielding film 44 is attached to the surface (outer or inner surface) of the shielding glass 100.
  • the purpose of attaching the solar heat shielding film 44 on the surface of the shielding glass 100 is the same as in attaching the solar heat shielding film 44 on the inner face of the external curtain wall 200.
  • the surface temperature of the shielding glass 100 is increased by the sunlight.
  • the surface temperature of the shielding glass 100 increases, consequently the air temperature between the external curtain wall 200 and the outer wall 22 increases. This increase in the air temperature generates an upstream air by means of the chimney effect.
  • the heated air ascends along the upstream air up to the upper end portion of the external curtain wall 200 and is discharged through the air stream exhaust port 220 and the forcible exhaust port 230.
  • the shielding glass 110 and the solar heat shielding film 44 are used to prevent radiation heat of the sun from reaching the internal space 33, and simultaneously generate an upstream air in the space between the external curtain wall 200 and the outer wall 22, so that the heated air on the surface of the shielding glass 100 can be blocked from being transferred to the internal space.
  • this shielding glass 100 is installed so as to be spaced apart from the external curtain wall 200 and also from the outer wall 22 by a certain distance, so that the upstream air can be induced in both the outer and inner sides of the shielding glass 100.
  • a fire-retardant damper 55 is installed at the boundary area between neighboring stories in the space between the outer wall 22 and the external curtain wall 200 of a high-rise building.
  • the fire-retardant damper includes a pivot slit so as to be closed and opened.
  • a fire-retardant damper 55 is installed at the boundary area between adjacent stories. Therefore, in the case of a fire, the pivot slit can be closed so that the fire can be prevented from propagating into the upper stories, which is caused by the upstream air.
  • the fire-retardant damper 55 may be configured in such a way that the pivot slit is automatically closed by sensing the fire (using a temperature or gas sensor), or is operated by a separate switch.
  • the external air suction port 210 is opened when the window 11 of the building is closed and an air cooler is operated. When the window 11 is closed, the external air is not supplied into the internal space and the internal air is not discharged. Thus, the external air suction port 210 is opened to introduce external air into the space between the external curtain wall 200 and the outer wall 22. The introduced air ascends to discharge, through the air stream exhaust port 220 or the forcible exhaust port 230, the heated air in the inner face of the curtain wall 200 or the surface of the shielding glass 100 to which the solar heat shielding film 44 is attached.
  • the external fresh air is supplied through the window 11 provided in the building side where the external curtain wall 200 is not installed.
  • the internal thick air is discharged through the window 11 provided in the building side, where the external curtain wall 200 is installed, into the space between the curtain wall 200 and the outer wall 22.
  • the discharged internal thick air ascends along the natural upstream air by means of the chimney effect, and is discharged to the outside through the air stream exhaust port 220.
  • the air blower 235 lifts forcibly the thick air and discharges it to the outside through the forcible exhaust port 230.
  • the solar heat shield film 44 is attached to the inner face of the curtain wall 200 or the surface of the shielding glass 100 to block radiation heat of the sun from reaching the internal space 33 and thus dramatically reduce the cooling cost during the summer time.
  • the solar heat shielding film 44 is not attached to the window 11 of the high-rise building, but the external curtain wall 200 or a separate shielding glass 100, so that the heated air in the inner face of the external curtain wall 200 or the surface of the shielding glass 100 is discharged to the outside along the upstream air between the curtain wall 200 and the outer wall 22, thereby enabling to prevent effectively the temperature increase in the internal space 33 caused by sunlight. If the solar heat shielding film 44 is attached directly to the window 11, it can block radiation heat of the sun, but the temperature increase in the internal space cannot be avoided, due to the heated air of the heated window 11.
  • the solar heat shielding film 44 does not always block all the sunlight, but par of visible lights can pass through the solar heat shielding film 44 to effectively block radiation heat of the sun while the right of a view is not infringed.
  • the fire-retardant damper 55 which has a pivot slit capable of being closed and opened, is installed at the boundary area between adjacent stories in the space between the external curtain wall 200 and the outer wall 22 of the building. When in a fire, the fire-retardant damper 55 is closed to prevent the fire from being propagated into the upper stories.
  • the heating cost in winter can be saved by controlling so as not to generate the chimney effect in the winter season.
