Description

  In the present invention, the space between the outdoor sash (hereinafter referred to as “outdoor sash”) and the indoor sash (hereinafter referred to as “indoor sash”) that are installed twice is defined from the floor side of the living room for each floor. Concerning airflow windows configured to allow air to flow through to the ceiling, mainly designed to prevent cold draft in the cavity part from flowing backward to the room side and inflow of condensed water into the room side It is.

  In general, a curtain wall using glass can obtain a view, but the heat insulation performance is not so good as compared with a normal wall, and there is a problem that the cooling efficiency is greatly lowered than a perimeter.

  Conventionally, as a countermeasure of this type, for example, as shown in FIG. 5A, the outdoor sash 30 and the indoor sash 31 are doubled at predetermined intervals to form a double window. By allowing air to flow from the floor side to the ceiling side for each floor between the indoor sashes 31 (hereinafter referred to as “cavity portion A”), the solar heat entering the living room 32 through the windows is mitigated. An airflow window is known in which a rise in room temperature is suppressed and the room temperature can be kept constant.

  In addition, as shown in FIG. 5B, for example, an outside air introduction type double skin that allows the outside air to flow through the cavity portion A is also known.

  In both types, partition members 33 are installed in the cavity portion A so as to have the same height as the floor of each floor. Moreover, the blind 34 is installed in the cavity part A for every floor.

  Further, in the case of an airflow window, as shown in FIG. 5A, a blowout port 35 for blowing air from the living room 32 side to the cavity portion A is provided near the floor surface of the indoor sash 31. The ceiling portion is provided with a suction port 36 for sucking air from the cavity portion A to the ceiling back side.

On the other hand, in the case of an outside air introduction type double skin, as shown in FIG. 5B, an outside air introduction port 37 for introducing outside air into the cavity portion A near the floor surface of the outdoor sash 30 is provided on the ceiling. There are provided outlets 38 for blowing the air in the cavity portion A to the outside.

  However, the former airflow window has a merit such that the cost is generally low due to the fact that an indoor blind can be used as the blind 34. On the other hand, dew condensation water generated inside the outdoor sash 30 is generated. There was a possibility that it would accumulate on the partition member 33 and flow into the living room 32 side from the blowout port 35, and the processing became a problem.

  In particular, in the early morning of winter, there is also a problem of a cold draft in which cold air flows backward from the ceiling side to the floor side and flows into the living room 32 side from the outlet 35 in the cavity portion A. Furthermore, since the partition member 33 is installed at the same height as the floor of each floor, there is a problem that the downward visibility is blocked by the partition member 33.

  In addition, because the partition member 33 is installed at the same height as the floor of the living room 32, the cavity part A is also easily regarded as a living room part in the current method. The building / floor area was calculated with the sash 30 side as the core, and the effective floor area could be narrowed accordingly.

  On the other hand, the latter outside air introduction type double skin has an advantage that the effective floor area can be widened because the area core can be the outdoor sash 30 side, but on the other hand, it is blind because of the atmospheric pressure in the cavity portion A. As 34, it was necessary to install a large-sized external blind.

  The present invention has been made to solve the above problems, and has a function as a conventional airflow window, while the cold draft in the cavity portion flows backward to the room side and the room side of the dew condensation water. It is an object of the present invention to provide an airflow window that can prevent inflow into the house and also a hot feeling in the living room in summer and can secure the effective floor area and view to the maximum.

The airflow window according to claim 1, wherein the airflow window is configured to allow air to flow from the floor side of the living room of each floor to the ceiling side between the outdoor sash and the indoor sash that are installed twice. Between the outdoor sash and the indoor sash, a lower partition member positioned lower than the floor of the living room and a transparent upper partition member positioned higher than the ceiling of the living room are attached to each floor. It is a feature.

  In the present invention, in the airflow window as described above, between the outdoor sash and the indoor sash, that is, in the cavity part, by installing the lower partition member installed for each floor so as to be positioned lower than the floor of the living room, Condensation water that occurs inside the outdoor sash and flows down on the partitioning member is prevented from flowing into the living room as it is, and the portion (space) below the floor surface of the living room in the cavity part receives cold air. By installing the lower partition member so as to be positioned lower than the floor of the living room, the downward partition of the lower part of the room can be prevented from falling by the air draft that flows through the cavity part from the ceiling side to the floor side. It is possible to ensure the maximum field of view by preventing it from being obstructed.

  In the case of the present invention, the outdoor sash can be a vertical curtain wall composed of a vertical frame, a plain, and a panel. In particular, glass with a film is used as the window glass of the outdoor sash, and pair glass is used for the window glass of the indoor sash. By using each, heat insulation performance can be improved and the room temperature of a living room can always be kept constant.

In addition, by installing transparent glass as a transparent upper partition member between the outdoor sash and the indoor sash so that each floor is higher than the ceiling of the living room, the spandrel part between the upper and lower living rooms is attached to the living room. It can be illuminated with light, which makes it easy to light up at night.

Further, by using a pair glass or a LOW-E pair glass as the upper partition member, heat loss of the through air can be prevented. In addition, LOW-E pair glass is a pair glass formed from the glass which gave the surface the LOW-E process (foil is stuck on the surface), and heat insulation is better than normal pair glass.

The airflow window according to claim 2 is characterized in that, in the airflow window according to claim 1 , an air outlet is provided between the outdoor sash and the indoor sash at a position lower than the floor of the living room for each floor. To do.

  In the present invention, the sash can be set to FiX (inserted window) by providing the outlet on the floor instead of providing the outlet on the indoor sash.

Airflow of claim 3, wherein the window is in airflow window of claim 1 or 2, is characterized in by comprising a transparent glazing is used indoors sash.

The airflow window according to claim 4 is characterized in that in the airflow window according to claim 1 or 2 , glass with film is used for the outdoor sash, and transparent pair glass or LOW-E pair glass is used for the indoor sash. Is.

The invention according to claims 3 and 4 can remarkably relieve the heat (hot feeling) of the room particularly in summer by using a pair glass with glass or a pair glass or a LOW-E pair glass for the sash. it can.

For example, in the case of the invention according to claim 3, it is 1 m away from the window surface under the conditions of a window height of 3 m, an exhaust air volume of 5 m @ 3 / hm, a heat flow rate of 1.09 W / m @ 2 ° C, and a solar radiation penetration rate of 0.14. The average solar radiation temperature at the spot was 27.9 ° C.

Further, in the case of the invention according to claim 4, it is 1 m away from the window surface under the conditions of a window height of 3 m, an exhaust air volume of 5 m 3 / hm, a heat penetration rate of 1.09 W / m 2 ° C, and a solar radiation penetration rate of 0.113. The average solar radiation temperature at the spot was 27.5 ° C.

In the case of a normal airflow window in which both the outdoor sash and the indoor sash are made of a single glass, the window height is 3 m, the exhaust air volume is 5 m ³ / hm, the heat flow rate is 1.16 W / m ² ° C, and the solar radiation penetration rate is 0.195. Under the conditions, the average solar radiation temperature at a point 1 m away from the window surface was 28.6 ° C.

  The present invention is as described above, and in particular, since the partition member installed for each floor is located between the outdoor sash and the indoor sash so as to be positioned lower than the floor of the living room, the inside of the outdoor sash Even if the dew condensation water generated on the glass flows down on the partition member through the glass surface, it does not flow into the living room as it is.

  In addition, a space below the floor of the living room of the cavity portion serves as a cold air receiving (space), thereby preventing a cold draft in which the cold air flowing backward from the ceiling side to the floor side flows into the living room side.

  Furthermore, since the partition member is installed so as to be positioned lower than the floor of the living room, even in the current method, the cavity part is not considered to be a living room part. In some cases, it is possible to obtain the maximum effective floor area by calculation.

  1 to 4 show an example of an airflow window according to the present invention. In the drawings, an outdoor sash 1 and an indoor sash 2 are doubled at a predetermined interval. Further, an upper partition member 3 and a lower partition member 4 are respectively mounted between the outdoor sash 1 and the indoor sash 2 (hereinafter referred to as “cavity portion A”), and the cavity portion A is located on the floor side of the living room 5 for each floor. Air flows from the ceiling to the ceiling.

The outdoor sash 1 is provided with a plurality of blinds 1b arranged at predetermined intervals in the vertical direction between a plurality of vertical frames 1a, 1a installed at predetermined intervals. The glass 1c is fitted in each frame formed by 1b, so that it is configured as a so-called vertical curtain wall that continuously covers the spandrel portion 6 between the living room 5 and the upper and lower living rooms 5, 5 on each floor, In particular, the seamless 1b is configured as a part of the lower partition member 3 and is attached together with the partition member 3 so as to be positioned at a predetermined height H ₁ lower than the floor surface of the living room 5 on each floor.

  The indoor sash 2 is installed for each room 5 on each floor. Moreover, although the single glass is used for the indoor sash 2 in principle, a pair glass is desirable in consideration of heat insulation. Moreover, the blower outlet 7 for blowing off air in the cavity part A from the living room 5 side is formed in the lower end part of the indoor sash 2 for every floor.

  Furthermore, the indoor sash 2 is provided with an opening 8 for entering and exiting the cavity portion A for each floor, and a door 8 a is attached to the opening 8. As shown in FIG. 4B, the outlet 7 may be formed on the floor of the living room 5 so as to communicate with the cavity portion A.

  A decorative panel 9 formed by attaching a ribbed steel plate 9b to a fireproof panel 9a is attached to the spandrel portion 6 of each floor.

The lower partition member 3 is attached to the floor ₁ of the living room 5 so as to be positioned lower than the floor surface of the living room 5 by a predetermined height H ₁ together with the above-described seamless 1b. A space 10 for receiving cold air for receiving cold air flowing backward from the ceiling side to the floor side is formed for each floor so that the cold air does not flow directly into the living room 5 from the outlet 7.

  In this case, the lower partition member 3 is formed by attaching a grating plate 3b on a bottom plate 3a made of a calcium silicate plate or the like. Further, a draining portion 1d for receiving condensed water that has flowed down the indoor surface of the outdoor sash 1 (glass 1c) is formed at the upper end of the seamless 1b.
