Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air barrier device for a window that prevents an outdoor heat load from affecting outdoor comfort through a window facing the outdoors.
[0002]
[Prior art]
FIG. 4 shows a room 6 provided with a window 4 facing the outdoor 2, in which conditioned air adjusted to an optimum temperature by an indoor air conditioner 8 is passed through a duct 10. It blows out from the blower outlet 14 provided in the ceiling 12. Further, a window air conditioner 16 is installed near the window of the room 6.
[0003]
This window-side air conditioner 16 blows cool air upward along the window 4 in the summer, blows warm air upward along the window 4 in the winter, and heat transmitted from the outdoor 2 through the window 4. The load is cut off.
However, according to the system of FIG. 4, in addition to requiring a lot of energy to produce hot air and cold air, even if conditioned air is blown out from the outlet 14 to the room 6 at an optimum temperature, the air conditioner for the window The warm air or cold air blown out from 16 mixes with the conditioned air and the room temperature changes, which may impair the comfort of the room 6.
[0004]
[Problems to be solved by the invention]
Therefore, as shown in FIG. 5, a Venetian blind 18 is installed inside the window 4, and instead of the window air conditioner 16 described above, an air supply fan that sucks indoor air and sends it upward along the window 4. 20 and an exhaust fan 22 that is arranged on the ceiling near the upper portion of the window 4 and sucks air from the window 4 and exhausts it to the back of the ceiling. The operation of the air supply fan 20 and the exhaust fan 22 activates the window 4 and the Venetian. There is also a system that creates a flow of air flowing from the lower part of the window 4 to the ceiling between the blind 18 and discharges the heat load from the outdoors 2 to the back of the ceiling with the air flow described above while also being shaded by the Venetian blind It is considered. In place of the Venetian blind 18 described above, there is a roll screen provided with a knitted screen for shading, although not shown.
[0005]
However, in the system of FIG. 5 as well, since a part of the air flow flows toward the interior 6 from the gap between the louvers of the Venetian blind 18 and the stitches of the screen of the roll screen, the interior temperature easily changes. It is difficult to maintain comfort.
Therefore, the present invention has been made in view of the above circumstances, and completely blocks the heat load from the outside from entering the room through the window, and maintains comfort by keeping the room at the optimum temperature. An object of the present invention is to provide an air barrier device near a window.
[0006]
[Means for Solving the Problems]
In order to solve the above problem, the air barrier device at the window of the present invention has a roll screen disposed inside the window, and air in a specific direction is placed in the space between the window and the roll screen in the vicinity of the window. An air flow generating means for generating a flow and exhausting the air to the outside is disposed, and the roll screen transmits the light but transmits the air and the first curtain material that does not transmit the air, and transmits both the light and the air. A screen formed by joining the second curtain material in a longitudinal direction to the end portion in the longitudinal direction, and a winding machine for moving the screen in the longitudinal direction so that the predetermined curtain material faces the window; Consists of.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of an air barrier system at the window of the present invention will be described with reference to FIGS. 1 to 3. The same components as those shown in FIGS. 4 and 5 are denoted by the same reference numerals, and the description thereof is omitted.
As shown in FIG. 1, in this embodiment, an air supply fan 20 is installed in the lower part inside the window 4. The air supply fan 20 is a device that sends out sucked room air upward along the window 4 from the fan outlet 20a. The indoor ceiling 12 near the top of the window 4 is provided with a vent 12a.
[0008]
A roll screen 22 is installed inside the window 4, and a space is provided between the roll screen 22 and the window 4 from the fan outlet 20 a to the vent 12 a.
The roll screen 22 includes a lower winder 24 disposed near the air supply fan 20, an upper winder 26 disposed on the back of the ceiling near the vent 12a, and the lower and upper winders. 24 and 26, and a screen 28 wound around. Here, the screen 28 has a longitudinal first curtain material 28a that transmits light but does not transmit air and a second curtain material 28b that does not transmit light and does not transmit air. It is comprised by joining an edge part. The first curtain material 28a is, for example, a flexible transparent resin curtain material, and the second curtain material 28b is, for example, a flexible black resin curtain material. Is used.
[0009]
The air supply fan 20, the fan outlet 20a, and the vent 12a provided in the indoor ceiling 12 correspond to the air flow generating means of the present invention.
According to the system configured as described above, the sealed space 30 is formed between the window 4 and the roll screen 22 by the screen 28 that does not allow air to pass therethrough. And by the action | operation of the air supply fan 20, the upward air flow generate | occur | produces in the sealed space 30 from the fan blower outlet 20a to the vent hole 12a.
[0010]
Here, in summer, the heat of the outside air enters from the window 4 due to the warm air of the outdoors 2, but most of the heat of the outside air is exhausted to the back of the ceiling by the air flow generated in the sealed space 30, Since the air flow is blocked from entering the room 6 by the screen 28, the temperature of the room 6 does not change and the comfort of the room 6 can be maintained.
Further, in the winter season, the outdoor 2 cool air is transmitted to the window 4 to take heat from the indoor 6 side. However, the air cooled by the air flow generated in the sealed space 30 is exhausted to the back of the ceiling. In addition, since the air in the room 6 moves to the window 4 side by the screen 28, the temperature of the room 6 does not change and the comfort of the room 6 can be maintained.
[0011]
Further, when the sunlight entering the room 6 is blocked, as shown in FIG. 2, the lower and upper winders 24 and 26 are rotated in the direction of the arrows, and most of the screen 28 facing the window 4 is made the second curtain. 28b. Sunlight is blocked by the second curtain material 28b, the temperature inside the room 6 is prevented from rising, and the comfort of the room 6 can be maintained. When putting sunlight into the room 6, as shown in FIG. 3, the lower and upper winders 24 and 26 are rotated in the opposite directions so that most of the screen 28 facing the window 4 is moved to the first curtain material 28b. To do. The sunlight passes through the first curtain material 28 a, so that the sunlight enters the room 6.
[0012]
As described above, according to the present embodiment, the sealed space 30 is formed between the window 4 and the roll screen 22 by the screen 28 that does not allow air to pass therethrough, and the air supply fan 20 operates to open the fan outlet 20 a in the sealed space 30. Since an upward air flow is generated up to the vent hole 12a, the heat load from the outdoor 2 through the window 4 can be completely blocked by the air flow. Can be maintained at the optimum temperature to maintain comfort.
[0013]
【The invention's effect】
As described above, according to the air barrier device at the window of the present invention, a sealed space is formed between the window and the roll screen by a screen that does not allow air to pass therethrough, and an air flow is generated in the sealed space by the air flow generating means. Therefore, it is possible to completely block the heat load from the outside from entering the room through the window by the air flow, and it is possible to maintain the room at the optimum temperature and maintain the comfort.
[0014]
Moreover, when the sunlight entering the room is blocked, the second curtain material that does not transmit both the light and the air constituting the screen is caused to face the window by the operation of the winder. As a result, the sunlight is blocked by the second curtain material, the temperature rise in the room is prevented, and the indoor comfort can be maintained.
