Description

[Detailed description of the invention] (Technical field) This invention relates to air conditioning in buildings, and improves the temperature environment especially near windows by ventilating indoor air using windows, thereby improving indoor air conditioning and heating. Concerning windows designed to reduce load.

(Prior Art) Buildings have traditionally been provided with windows for purposes such as letting in sunlight, while office buildings and the like use air conditioning to maintain a constant temperature inside the building. However, when cooling the room, heat enters from outside through the window, and when heating the room, heating heat escapes from inside the room, so extra energy is consumed for air conditioning. For this reason, conventional efforts have been made to reduce the amount of heat entering and exiting the window by making the window a double-glazed structure and forming an air layer between the double glass plates.

However, double-glazed windows do not sufficiently improve the temperature environment inside the room, especially near the windows.
When radiant heat is considered in addition to indoor air temperature, the temperature felt by the human body (hereinafter referred to as the working temperature), which is composed of the indoor air temperature and the average radiant temperature, increases during cooling and decreases during heating, and the energy used for air conditioning increases accordingly. An increase in the amount used was unavoidable.

That is, during cooling, the indoor glass is directly heated, or the outdoor glass and the air inside the double-glazed window are heated by solar heat rays that directly irradiate the window and heat rays from the sky that diffuse into the atmosphere and irradiate indirectly. These heated the indoor side glass, and heat entered the room due to radiant heat from the indoor side glass plate and heat transfer to the indoor air. In addition, even on cloudy days when there was no direct sunlight, a similar amount of heat penetrated through the indoor glass panel heated by the heat rays from the sky and the outside temperature.

Particularly during heating, there is a large temperature difference between the inside and outside, and the temperature of the indoor glass plate becomes low due to heat transfer and radiation through the air layer between the outdoor glass plate and the double-glazed window. Therefore, the heat radiated from the heated indoor objects and human bodies is absorbed by the cooled indoor glass plate and radiated away.

On the other hand, in buildings such as buildings where many people live, the amount of ventilation required per person is regulated, and the conditioned air inside the room is discharged outdoors by some method.

(Purpose of the invention) The purpose of the invention is to effectively utilize the exhaust of indoor air to the outdoors for ventilation, which was also required for air conditioning in conventional buildings. A window that reduces energy consumption for air conditioning by increasing the operating temperature.In other words, by discharging indoor air through the space formed between the double-layered glass panels, the indoor glass panel is heated and the effect near the window is increased. To provide a window that lowers or increases the temperature, and also allows the air heated by the solar heat to be circulated between the double-glazed windows indoors on surfaces exposed to sunlight in winter, thereby reducing energy consumption for air conditioning. That's true.

(Structure of the invention) The above purpose is to form a space whose lower part communicates with the sky between the two inner and outer glass plates surrounded by the window frame, and A cross-flow type fan is provided in the space so that the suction side of the fan faces the space, and the space between the glass plates is connected to the inside and outside of the one window frame material through the internal space of the window frame material. The gap leading to the outdoor exhaust port is formed in a labyrinth shape with a hanging wall, a rising wall, and a water return provided at the upper end of the rising wall. A damper is provided inside the window frame material to selectively guide the air flow blown by the fan toward the indoor exhaust port or the outdoor exhaust port on the blowout side of the window frame material, thereby reducing energy consumption for air conditioning. This is achieved by windows.

(Embodiments) Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, a rectangular window frame composed of an upper frame 1, a lower frame 2, and a vertical frame 3 is attached to an opening formed in the outer wall of a building. A rectangular double glass shoji corresponding to the window frame is fitted into the window frame.

The shoji has a shoji main body 8 in which an outdoor glass plate 7 is fitted into a framework composed of an upper casing 4, a lower casing 5, and a vertical casing 6.
and a small shoji 10 attached to the indoor side of the shoji main body with hinges 9. Similarly, the small shoji 10 has an upper case 11,
An indoor glass plate 14 is fitted into a frame composed of a lower casing 12 and a vertical casing 13, and can be opened indoors by hinges 9. The illustrated shoji is attached to a window frame via a rotating shaft 15 in the form of a horizontally rotating window.

As can be seen from Fig. 3, a space 16 that opens upward and downward is formed inside the shoji, and a blind 1 is formed within the space.
7 may be provided. Further, when providing a blind, it is convenient to use a known blind that is formed so that it reflects solar heat outdoors in the summer and absorbs solar heat and is heated in the winter. This example uses such a blind. Further, an indoor air intake port 18 communicating with the interior of the space 16 is provided with a shutter 19 that can be opened and closed.

The structure of the upper frame 1 will be explained with reference to FIG. 3. A hanging wall 21 is provided in a hanging shape from the outdoor end of a ceiling wall 20 that extends almost horizontally in the indoor and outdoor directions of the upper frame. The first one from the lower end of the hanging wall 21
A bottom wall 23 that slopes upward extends toward the indoor side with a gap 22 (corresponding to an outdoor exhaust port described later). A rising wall 24 rises from the indoor end of the bottom wall 23 in a manner substantially parallel to the hanging wall 21. A water return 25 having a U-shaped cross section is provided at the upper end of the rising wall 24, and a second gap 26 is formed between the water return 25 and the ceiling wall 20.

Further, an indoor vertical wall 27 extending downward is provided at the indoor end of the ceiling wall 20. This vertical wall 27 has an upper end hooked to the ceiling wall 20, a lower end formed in the shape of a cover screwed to the auxiliary upper frame 28, and an indoor side exhaust port 29 formed in the shape of a grid fitted in the upper part.
As described above, the upper frame is composed of the ceiling wall 20, the bottom wall 23, and the auxiliary upper frame 28, which are fixed to the vertical frames 3, 3.

An indoor space 30 is formed by the ceiling wall 20, the rising wall 24, and the indoor vertical wall 27. This space 30 is open at the bottom and communicates with the space 16 between the glass plates. At the lower part of the space 16 is a cross-flow fan 3 such as a cross-flow fan that sucks air between the spaces 16 and discharges it upward.
1 is fixed to a rising wall 24, for example. Further, in the indoor space 30 and above the cross-flow type fan 31, a damper 32 is provided which rotates so as to alternately open and close the second gap openings 26 and 29 from the cross-flow type fan 31. The cross-flow type fan 31 can be operated from the indoor side by a switch, and the damper 32 can be operated by a conventional means such as a link mechanism.

In operation, when a fan 31 disposed in the space 30 is operated, the opening/closing valve 19 made of lightweight material such as plastic or aluminum foil, which opens automatically due to the negative pressure, is opened in the space 1 by the suction force of the fan.
6 Open the indoor air intake port 18 at the bottom of the damper 3.
2 is set to the position shown by the solid line in FIG. 3 and the cross-flow type fan 31 is turned, indoor air enters the space 16 through the intake port 18 and is discharged into the room through the indoor side exhaust port 29. At this time, even when it is raining, the second gap 2
6 is almost blocked by the damper 32 and there is a hanging wall 21 on the outdoor side, so rainwater does not enter the upper frame 1. In addition, even if a small amount of rainwater enters due to strong winds, etc., the floor wall 2 slopes downward toward the outdoors.
3 drains water, and since there is a water return 25 on the rising wall 24, the water is completely waterproof.

When the damper 32 is turned to the position indicated by the two-dot chain line, the indoor air is similarly discharged outdoors through the outdoor exhaust port 22. In this case, since the airflow has an outward velocity, there is no need to worry about rainwater intrusion.

In order to facilitate maintenance and repair of the cross-flow type fan 31, in the present invention, the indoor vertical wall 27 is formed in the shape of a removable cover, and the indoor side exhaust port 29 is formed with a fitted grid member. It can be removed and cleaned separately.

In the present invention, a rotating window with a space 16 provided therein has been described, but it may also be formed into a closed window.

(Effect of the idea) During cooling, part of the cold air inside the room is transferred to the space 16.
When the air is discharged outdoors through the indoor glass plate 17, the air in the space 16, which has been heated by heat transfer through the indoor glass plate 17, is cooled down by the low-temperature indoor air. Therefore, the indoor surface of the outdoor glass plate 7 and the outdoor surface of the indoor glass plate 14 are cooled, the radiation of heat from the indoor glass plate is reduced, and the operating temperature in the indoor area near the indoor glass plate is reduced. Also, during heating, when the temperature in the space 16 is lower than the indoor temperature, if the air is exhausted outdoors in the same way as described above, the temperature of the outdoor surface of the indoor glass plate will rise. This eliminates the escape of heat through the indoor glass plate due to heat transfer from the indoor air, and in particular, eliminates heat radiation from the human body toward the indoor glass plate, thereby reducing the operating temperature inside the room. In any of the above cases, energy consumption for air conditioning can be reduced.

Furthermore, during heating, when the temperature in the space 16 is higher than room temperature, circulating this warm air indoors through the indoor exhaust port helps to reduce energy consumption for indoor air conditioning. Furthermore, since a cross-flow type fan is used, the air between the windows can be exhausted in a predetermined direction over a wide area, so that the above-mentioned energy saving effect can be effectively generated.

In addition, to prevent rainwater and moisture from entering the air passing through the fan, indoor air is sucked in and discharged outdoors, and there is also a maze-like gap on the outdoor exhaust side of the fan, even if rainwater accompanied by the wind is generated. This prevents rainwater from reaching the fan. Therefore, there is no possibility that the fan portion will be damaged by rainwater or moisture.
