(Example)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a view schematically showing a vertical section of a window space portion of an air barrier fan device according to one embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a window glass facing the outside of a building (for example, a high-rise building whose entire surface is covered with glass) 2, and also shows upstairs and downstairs of the same structure.
Reference numeral 3 denotes a living room on the indoor side, which is constituted by a floor surface 4 and a ceiling 5. Reference numeral 6 denotes a roll (type) blind, which forms a window space 7 (forms an air barrier space) between itself and the inside of the window glass 1 facing the outside. The roll blind 6 is moved up and down (operated) to an appropriate position by a winding machine (not shown) attached to the ceiling 5, and when the air barrier fan 8 is operated (described later), the lower end of the roll blind 6 is moved. The setting is made in advance so as to form a slit-like gap 11 having a predetermined dimension between the step 9 and the step portion 10. The lower end 9 of the roll blind 6 also serves as a weight (for stretching or for preventing runout), a linear tool for forming a gap 11 (slit-shaped suction port), and the like.
A lower part of the window space 7 is provided with a stepped portion 10 slightly higher than the floor surface 4 of the living room 3, and a fence-shaped air barrier fan 8 is installed in the window space 7. Reference numeral 13 denotes a support in the middle of the air barrier fan 8, and both ends of the air barrier fan 8 are supported by, for example, a pillar 14 (FIG. 4 described later) and a wall 15 (FIG. 4 described later). Wiring for controlling the operation of the air barrier fan 8 is provided inside the column 13.
[0016]
FIG. 2 is a schematic longitudinal sectional view showing details of the essential part of FIG. 1, and FIG. 3 is a schematic longitudinal sectional view of an air barrier fan.

Is housed in a cylindrical fence 12 having a cross section, for example (the fence 12 is also used as a casing).
Further, a cover (opening / closing lid) or the like is provided at the corresponding portion of the fence 12 for the operation panel 18 for operation (for switches), maintenance, and the like. The air barrier fan 8 is assumed to be a generic term for these (hereinafter the same).
In this embodiment, the outermost diameter of the fence 12 is 120 mmφ, and the length of the internal cross flow fan is 300 mm and 500 mm. The air barrier fan 8 is installed at an intermediate position where the height is 600 mm above the floor 4, the horizontal distance in the window space 7 is 265 mm from the window glass 1, and 180 mm from the roll blind 6.
The material of the fence 12 and the struts 13 is basically made of metal (for example, an extruded aluminum material; a coating film can be applied) from the viewpoint of strength. However, since electric equipment such as a cross flow fan is provided inside, the casing is used as a casing. Obviously, grounding is an essential requirement. In this sense, it is also possible to use a resin (free coloring in consideration of danger indications and the like).
The step portion 10 is 100 mm slightly higher than the floor surface 4 and forms a lower portion of the window space 7.
The roll blind 6 is basically made of a material having no air permeability (the light transmittance and the material thereof are not limited), but has an adverse effect on the effective formation of the window space 7 (which becomes a main part of the air barrier system). Any material can be used as long as it does not affect the air permeability.
In this sense, a slat (formula) blind is not preferable because it causes turbulence in the airflow and loss in reducing the air volume (wind speed).
[0017]
The gap 11 between the lower end 9 of the roll blind 6 and the stepped portion 10 is 15 mm, and the air in the living room 3 is drawn into the air inlet 16 of the air barrier fan 8 from the gap 11 by the operation of the air barrier fan 8. (Sucked). The sucked air is blown out from the air outlet 17 of the air barrier fan 8 and is blown upward in the window space 7.
The air inlet 16 and the air outlet 17 of the air barrier fan 8 are both opened in parallel in a slit shape in the circumferential direction of the fence 12, and the opening area is the same for the air inlet 16 and the air outlet 17. Designed. In addition, the intake angle a of the intake port 16 is set in a range of “vertically downward to the gap 11 (or the lower end portion 9) (short-circuiting)”, and the blow angle b of the outlet 17 is set to “horizontal”. From 45 ° to 60 ° obliquely upward (toward the window glass 1). The air blowing speed of the air barrier fan 8 is set at 1 to 1.5 m / sec, and the air blowing amount is set at 50 to 100 m ³ / h.
Each of these set values (dimensions) is such that the roll blind 6 does not shake or shake or emit noise due to the air blow by the operation of the air barrier fan 8 (in such a state as to cause occupants to feel uncomfortable). Not designed).
[0018]
Ventilation in the window space 7 by the air barrier fan 8 flows (via) to a duct (not shown) and an air conditioner (not shown) in the five ceilings (in the ceiling, behind the ceiling, etc.), and again in the living room 3. To form a circulation airway. That is, by operating the air barrier fan 8 in the window space 7, an effective circulation air path (air barrier system) can be formed.
In other words, the radiant heat (amount) is detected as a measure against radiant heat in summer (reduction of solar radiation load) and interlocked with the air conditioner (operation control), or the outside temperature is detected as a measure against cold draft and dew in winter. Can be selected to be linked (operation control) with an air conditioner or the like, and an energy saving effect is generally generated. The details of the spring and autumn are not described in detail, but the operation of the air conditioner, the operation of the air barrier fan 8, the operation of the roll blind 6, and the like are appropriately selected according to the situation (necessity).
[0019]
The operation (control) operation of the air barrier fan 8 includes selection of ON to OFF in conjunction with an air conditioner and selection of high to medium to low air flow (air blowing speed) via an operation panel 18 (FIG. 4 described later). Can be done freely. The operation (control / operation) of the air barrier fan 8 is designed for each individual air barrier fan 8 or for each specific block of the air barrier fan 8 according to the size of the living room 3, the purpose of use, the use, the frequency, and the like. -The settings are made.
Reference numeral 19 denotes a (natural) ventilation opening for outside air into the living room 3, and the lid is manually opened and closed as appropriate. Reference numeral 20 denotes an outside air intake (downstairs), which is used for taking outside air into the air conditioner.
As described above, the window space 7 constituted by the fence 12-shaped air barrier fan 8 and the stepped portion 10 makes the section of the living room 3 and the floor surface 4 special, so that the window space 1 approaches the window glass 1 facing the outside. It has a configuration to prevent danger.
That is, structurally, it is configured such that it is difficult for a person to step into the window space 7 and enter the window space 7 (it is more effective if the color tone is devised) (it is not close to the window glass).
[0020]
Furthermore, since the window space 7 is composed of the slightly high step portion 10 and the roll blind 6, dust and dirt enter the window space 7 from the inside of the living room 3 and become trapped in the window space 7. In other words, it is possible to configure the partition as a section for facilitating cleaning work on the floor surface 4 in the living room 3 by preventing, that is, garbage and the like staying at the step portion 10 in the front.
At the same time, with respect to the operation of the air barrier fan 8, the suction (intake / inflow) of dust and the like from the floor 4 in the living room 3 is positively reduced by the roll blind 6 and the gap 11 between the steps 10. Therefore, the frequency of cleaning / replacement (maintenance) of the filter in the air barrier fan 8 can be reduced.
