Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention Field of the Invention The present invention is a window of a building, particularly a window suitable for an office building. More specifically, it is a double window having two glass inside and outside, and has excellent heat load low-range effect and thermal environment improving effect of exhausting indoor air to the outside through the space inside the double window. .

2. Description of the Related Art Recently, air-conditioning equipment is installed in buildings, and many of them constantly control the room temperature to a constant temperature. Most office buildings are equipped with this air conditioning system. With this air conditioning system, the temperature inside the room is controlled to be appropriate for human activities during the summer and winter. Normally, the room is kept at a uniform set temperature according to the season.

By the way, windows are always installed in buildings. Glass is fitted in this window. As is well known, glass has poor heat insulation and has a small heat capacity. In addition, it is easy for sunlight to pass through. Therefore, the window is easily affected by outside weather conditions such as outside temperature, wind, and sunlight. Therefore, the heat loss or heat acquisition from the window is larger than that of the general outer wall. Further, since glass is easily affected by the outside air temperature, the glass temperature is higher than the room temperature set value in summer and lower in winter, and the long-wavelength radiant heat from the glass surface deteriorates the living environment near the window. If solar radiation transmitted through glass is added to this, the living environment will be further deteriorated. Therefore, even if the room temperature is kept constant by the air conditioning equipment, the living environment in the vicinity of the window is worse than that in the place away from the window. Taking this into consideration, taking measures such as lowering the set temperature in summer and increasing the set temperature in winter increases the energy consumption of air conditioning. Therefore, various measures have been conventionally made to reduce heat loss or heat acquisition from windows. The simplest is to install blinds on the windows.
In addition, the window itself is a double-glazed window with two inside and outside glass attached,
It is well known that improved ones such as a double window with a built-in blind in which a blind is provided in the space of the double window have appeared. The double glazing with a built-in blind is the most efficient, and the heat loss at low temperature in winter can be reduced to about 1/4 of that with a blind.

However, the methods such as installation of blinds, double glazing, and double glazing with built-in blinds are mainly aimed at heat loss or the low range of thermal lodging, and are not intended to improve the thermal environment near the window. There wasn't. Therefore, for example, when there is insolation, the indoor glass temperature of the blinds and double windows with built-in blinds installed in the room is 10 ° C or more higher than room temperature in the worst case. Residents feel very hot. If the long wavelength radiation environment near the window can be improved, the room temperature setting temperature can be relaxed,
A great energy saving effect can be obtained. Room temperature set temperature is 1
It is said that air conditioning energy consumption can be saved by 10% if the temperature is relaxed.

In consideration of these, the applicant has proposed a double-glazed window in which the air in the room is exhausted to the outside through the space between the inner and outer windows (Japanese Patent Application No. 57-220330). According to this, since the air in the room is brought into contact with both surfaces of the glass on the room side, the temperature of the glass can be brought close to the room temperature. Therefore, long-wavelength radiation from the window member was mitigated, and the actual thermal environment was improved. Furthermore, since the air passing through the glass collects and removes the heat immediately before entering the room, for example, the solar heat absorbed by the blinds, the heat load is greatly improved.

Further, in a building such as a building in which a large number of people live, the required amount of exhaust gas per person is regulated, and the air-conditioned air in the room is wastefully discharged to the outside by some means. The air part of the double window is used to exhaust the indoor air to the outside through the air part (hereinafter referred to as the ventilation window). In addition to being excellent, it is possible to improve the low heat load from the window and the thermal environment near the window by using the exhaust function, and it is also useful for reducing the air conditioning duct equipment.

Problems to be Solved by the Invention In office buildings, continuous windows are often used.
The exhaust port is always open to the outside, connecting the inside and outside of the room. Therefore, there is a possibility that rainwater may enter when it rains, and in the case of continuous windows, since each window is provided with an exhaust port, the possibility of rainwater entering increases.

Also, when exhausting air using a blower, the conventional ventilation windows must be equipped with individual blowers, which is uneconomical, and at the same time, noise from the blowers overlaps and the overall noise level becomes considerably large. It will be different.

In addition, the installation of the blower has a disadvantage that the window opening area is narrowed.

Therefore, the object of the present invention is to provide a continuous window which has an effect as a ventilation window, keeps the thermal environment in the vicinity of the window good, reduces noise in the vicinity of the window, and has less possibility of rainwater infiltration. It is to be.

[Structure of the Invention] Means for Solving the Problems In the present invention, a plurality of double windows having two glass inside and outside, in which a space portion is provided between the glasses, are continuously arranged with a vertical side interposed therebetween. In addition, a suction port for sucking indoor air into the space is formed at one end of all the windows, and a duct for passing the air sucked into the windows is formed at the other end of the window. The auxiliary member having a cross-sectional shape substantially equal to the cross-sectional shape of the duct is attached to the end of the window on the side where the duct is provided, and the duct of each window is connected to the auxiliary member, or by avoiding uprightness, all An exhaust device for communicating the window ducts and further for exhausting air to the outside through the communicating ducts is provided at one location common to all the windows, and the flow rate adjusting means is provided in each of the windows or the air passage to the duct in each window. Is provided.

The structure of the windows is exactly the same regardless of whether they are arranged horizontally in parallel or vertically. In the case of the windows arranged side by side, the inlets may be provided on either the upper or lower side, and the vertically parallel ones may have the inlets on the left or right.

Action There is suction on the indoor side of each window, and a duct is formed at the opposite end where the suction port is provided, and the exhaust system is connected to this duct, so the air in the room is doubled from the suction port of each window. It flows into the duct through the space of the window and is exhausted from the duct to the outside by the exhaust device. That is, the window itself can be exhausted. Moreover, since the air in the room passes through the space of the double window during the exhaust, the glass on the indoor side comes into contact with the air in the room on both sides and approaches the temperature in the room. Therefore, heat radiation and cold heat radiation from this glass are eliminated, and the thermal environment near the window is improved.

It is desirable that the exhaust device has a built-in blower,
In the case of a room in which air can be exhausted by utilizing the pressure difference between the inside and outside of the room by the air conditioning equipment for air conditioning the room, the exhaust device may have only an exhaust port.

Example FIG. 4 is a front view of an example as seen from the inside of the room, in which an upright frame 3 and an upright frame 3 are provided between the upper frame 1 and the lower frame 2, and vertical frames 4, 5 are formed at the left and right ends.
The shoji screens 6, 6, 6 are mounted in the frame frame by and. In this embodiment, three windows are arranged side by side in parallel, but two or more windows may be arranged side by side. As shown in FIG. 1, these shoji screens are made up of two sheets inside and outside, and have glasses 7 and 8, respectively. A space 9 is formed between the shoji screens, and a blind 10 is attached to the space. As shown in FIG. 3, each shoji screen is attached to the frame body by a hinge 11 so as to open to the indoor side. The shoji screen may have any shape. The shoji on the indoor side is attached so as to be spaced apart from the lower frame 2, and the space between them is used as the suction port 12. In this embodiment, the suction port is formed by changing the mounting position of the shoji as described above, but depending on the shape of the lower frame, a hole may be formed in the lower frame to serve as the suction port. Further, the suction port may be provided in the stile to which the glass is attached.

The upper frame 1 is a long one common to each window, and is made of an aluminum alloy extruded into a cross-sectional shape shown in FIG. Of course, it is not limited to this. The inside of the upper frame 1 is opened toward the space portion 9, and this space serves as a duct portion 13. Duct part 13
An air volume adjusting plate 14 is attached to the boundary between the space 9 and the space 9. The air volume adjusting plate 14 is provided to make the amount of air passing through the space 9 of each window substantially equal, and a window having a large air resistance is attached to a window close to the exhaust device and a piece having a low air resistance is attached to a distant window. To be In this embodiment, the upper frame 1 itself is a duct as described above, but the duct may be formed separately from the frame.

As shown in FIG. 2, the upright 3 is fixed to the upper frame 1 by a short auxiliary member 15 made of a metal material such as stainless steel, which is formed to have the same shape as the inside of the duct portion 13 of the upper frame 1. That is, the upper surface of the auxiliary member 15 is fixed to the upper frame 1 with screws 16 and 16, and the partition 18 of the vertical 3 is attached to the bracket 17 fixed to the lower surface thereof. Since the auxiliary member 15 is a plate-shaped member and is formed to have a space, the duct portion 13 is not blocked at this portion.

An exhaust device is provided on either of the left and right vertical frames 4 and 5 (5 in this embodiment). The exhaust device of this embodiment is shown in FIG. 5, and is connected to the upper frame 1 at the upper end and has a blower 19 in the middle.
Is attached, and an exhaust port 20 facing the outside is formed at the lower end. A damper 20a is mounted on the exhaust port 20 to rotate when air flows backward to close the interior of the vertical frame 5. The shape of the damper is not particularly limited, and any damper may be used as long as it operates when the positive air pressure outside the room rises and flows backward from the exhaust port 20 and closes the inside. Further, the installation position may be anywhere. Although the blower 19 uses an axial flow fan, it is possible to use a fan that is appropriately small and has low noise.

The exhaust device of this embodiment is composed of a blower 19, an exhaust pivot 20 and a damper 21. The air is exhausted by utilizing the pressure difference between the inside and outside of the room caused by the blowing pressure of the air conditioner for air conditioning the room. It is not necessary to provide 19. Further, the exhaust port 20 may be in the middle or above instead of below the vertical frame 5.

Since this embodiment has the above-mentioned configuration, when the blower 19 is driven, the air in the room is sucked from the inlet 12 of each window to the duct portion 13 of the upper frame 1 through the space portion 9 and from the exhaust port 20 through the duct portion 13. Exhaust outdoors. At this time, since the air in the room passes through the space 19 and comes into contact with the back surface of the glass 7 as described above, the glass 7 approaches the temperature of the air and eliminates heat radiation in the summer and cold radiation in the winter, thereby reducing the heat environment near the window. Can be improved. That is, it can function as a ventilation window.

The indoor air is sucked in through the suction port 12 of each window and is sucked almost uniformly by the air volume adjusting plate 14, but exhaust is performed only by the exhaust device provided in the vertical frame 5.
Only one blower 19 is required. Also, the exhaust port is 1 as a whole.
Only in places. Therefore, noise is less likely to occur, and the possibility of rainwater intrusion is less than that of an individual exhaust port. In this embodiment, the exhaust device is formed on the right vertical frame. However, when there are many windows, a vertical frame having an exhaust device is installed in the middle of each window so that air can be sucked evenly from both left and right windows. Is desirable.

FIG. 6 shows a case where a plurality of windows are arranged vertically in parallel,
A vertical frame 2 in which the suction ports 21 and 21 serve as ducts on the left side in the drawing
2 is located on the right side. An exhaust device having a blower 23 and an exhaust port 24 is attached to the lower side of the vertical frame 22 as shown in FIG. If the exhaust port is directed right below as shown in the figure, the intrusion of rainwater can be reliably prevented. In this case, the blower 23 may be directly attached to the exhaust port 24 facing downward.

[Advantages of the Invention] As described above, according to the present invention, since the air in the room is exhausted to the outside through the space of the double window, the glass on the indoor side is brought close to the temperature of the air in the room and further passes between the glasses. Since the heat immediately before entering the room into the room, for example, the heat absorbed by the blinds is collected and eliminated, it is possible to improve the thermal environment near the window in the room and reduce the heat load from the window.

In addition, the intake ports are formed in each of the windows, and the common duct leads to the exhaust device so that the exhaust air can be exhausted from one exhaust device, so even if a blower is installed, only one is required, which is economical. At the same time, there is less noise. Also,
Since there is only one exhaust port, the absolute amount of infiltration of rainwater is small,
Therefore, the possibility of rainwater intrusion is reduced, and the means for preventing rainwater intrusion is also simplified.

Further, according to the present invention, since the flow rate adjusting means is provided in the air passage from the space portion to the duct in each window, even if one exhaust device is commonly used for a plurality of windows, the inflow amount of air into each window can be reduced. It can be kept constant and the indoor environment can be kept almost uniform.
