Description

  The present invention relates to an air-conditioning outlet installed on the back of a ceiling in a building as a part of an air-conditioning facility, and an air-conditioning system using the same.

  In conventional perimeter air conditioning, a line-type air outlet having a slit-like air outlet is used, and air-conditioning air is blown from the air outlet over the entire window surface to perform air conditioning load processing on the window surface. In particular, in the case of a system ceiling formed by arranging T-bars in a grid pattern, a typical line-type air outlet for the system ceiling employed in this system has a longitudinal dimension of about 1000 mm.

  On the other hand, as a prior art related to the present invention, for example, there is a “linear air outlet” described in Patent Document 1. This “linear air outlet” is used by being attached to the ceiling surface of a building, and has an elongated linear opening for blowing cool air or warm air toward the room.

Japanese Utility Model Publication No. 51-31342

  In recent years, in the system ceiling method, as shown in FIGS. 20 and 21, the adoption of a grid ceiling 1 (lattice ceiling) formed by arranging a plurality of T bars 2 in a grid at intervals of 600 mm has become mainstream. Yes. When a conventional line ceiling outlet 200 for system ceiling is used for such a grid ceiling 1, the line outlet 200 does not fit within the range of one grid (unit grid), so one It must be installed across the area of two unit cells across the T-bar 2. For this reason, the conventional line-type outlet 200 is difficult to handle, and a great deal of labor is spent on transportation to the site and construction.

  Moreover, when installing the line-type outlet 200 over the area | region for two unit grids in the state straddling T-bar 2, it is necessary to notch the part 201 which interferes with T-bar 2 in the outlet main body 203. Therefore, not only is it difficult to generate an airflow that hits the entire window surface, but the shape of the outlet body 203 is complicated, and the manufacturing process becomes complicated.

  Further, as described above, in the case of the line-type air outlet 200 for the system ceiling, the portion 201 that interferes with the T-bar 2 of the air outlet body 203 is cut out, so that the conditioned air flow blown out from the air outlet 202 is changed. There is no residual wind speed at the lower part of the duct connection port 204. For this reason, the airflow distribution from the blowout opening 202 is divided into right and left as shown by the curves 20w and 21w in the figure, and is concentrated on both ends of the blowout opening 202, and is therefore uniform on the window surface. As a result, the heat load processing of the perimeter cannot be performed efficiently.

Note that a curve 20w in FIG. 20 shows that when the cooling air having an air volume of 300 m ³ / h is supplied to the system ceiling line-type air outlet 200, the final air velocity in the air flow that blows out from the air outlet 202 is 0. The part which is 5 m / s is shown. Further, a curve 21w in FIG. 21 shows that when the heating air having an air volume of 300 m ³ / h is supplied to the system ceiling line-type air outlet 200, the final air velocity is 0 in the cooling air flow blown out from the air outlet 202. The part which is 5 m / s is shown.

  On the other hand, in the field of air conditioning equipment for buildings, downsizing of air-conditioning outlets (particularly, line type outlets for system ceilings) is required. Reducing the size not only narrows the conditioned air diffusion area in the longitudinal direction of the blowout opening, but also increases the noise of the blown airflow generated from the blowout opening, so it is not possible to deal with simple size reduction alone. is there. Such problems in the air-conditioning outlet cannot be solved even if the “linear air outlet” described in Patent Document 1 is used.

  Therefore, the problem to be solved by the present invention is to achieve a reduction in the size of the air-conditioning outlet while ensuring a wide conditioned air diffusion region in the longitudinal direction of the outlet opening and reducing the size of the air-conditioning outlet. It is an object of the present invention to provide an air-conditioning outlet and an air-conditioning system using the same, which can suppress the noise level of the blown airflow generated from the outlet opening during the air-conditioning operation that increases due to the air-conditioning operation.

In order to solve the above-described problems, the air-conditioning outlet of the present invention is
In order to blow out the conditioned air supplied from the air conditioner into the room, it is a line type air conditioning outlet installed on the ceiling,
A chamber having a substantially trapezoidal shape when viewed from the front, an air inlet opening at the front of the chamber, and a slit-like outlet opening at the bottom of the chamber;
A plurality of diffusion vanes for diffusing conditioned air blown from the blowout opening toward the indoor space in the longitudinal direction of the blowout opening are disposed in a region upstream of the blowout opening in the chamber. To do.

  With such a configuration, it is possible to ensure a wide diffusion region of the conditioned air that blows out from the blowout opening so as to expand in the longitudinal direction of the blowout opening, while realizing downsizing of the air conditioning blowout. For this reason, the conditioned air blown out from the blowout opening can be widely diffused in the required region. Further, it is possible to minimize the noise level of the blown airflow generated from the blowout opening that increases due to the downsizing of the air conditioning blowout.

  In addition, the diffusion vane provided in the upstream area of the blowout opening in the chamber diffuses the conditioned air blown from the blowout opening toward the indoor space over a wide range while being a compact air-conditioning blowout opening. Therefore, it is possible to ensure the same performance as that of the conventional-sized line-type air-conditioning outlet while ensuring the remaining wind speed of the conditioned air blown out from the vicinity of the lower portion of the air inlet of the outlet opening.

Here, in the air outlet for air conditioning, the plurality of diffusion vanes are arranged at a plurality of positions symmetrical with respect to the center line of the chamber passing through the center in the longitudinal direction of the outlet opening of the chamber. Is arranged in an opposite inclined posture that is symmetric with respect to the end,
An inclination angle of the first diffusion vane disposed at a position closest to the center line is an angle closer to a vertical than an inclination angle of the inclined wall portion of the chamber;
The inclination angle of the plurality of second diffusion vanes arranged closer to the inclined wall portion than the first diffusion vane is an angle closer to the horizontal than the inclination angle of the inclined wall portion,
It is desirable that an inclination angle of the third diffusion vane disposed at a position closest to the inclined wall portion is substantially equal to the inclined wall portion.

  With such a configuration, the conditioned air that has flowed into the chamber from the air inlet passes between the plurality of first diffusion vanes, second diffusion vanes, and third diffusion vanes having different inclination angles, whereby the chamber The diffusion region in the longitudinal direction of the blowout opening of the conditioned air flow blown out from the blowout opening toward the indoor space is greatly enlarged.

  As a result, the diffusion region of the conditioned air flow blown out from the blowout opening of the chamber toward the indoor space can be secured up to about 2 to 4 times the longitudinal size of the blowout opening. In addition, the size of the chamber that forms the air conditioning outlet is smaller than that of the conventional product, but the remaining air velocity at the lower part of the air inlet (lower part of the duct connection port) is ensured while being equivalent to the conventional size of the line type air outlet. The air diffusibility can be realized.

  Further, by providing a plurality of first diffusion vanes, second diffusion vanes, and third diffusion vanes, a predetermined residual wind speed (for example, a residual wind speed of 0.5 m / s at FL + 1200 at a fixed position from the floor of the room) ) Can be secured, and stable air conditioning can be realized.

  In the air conditioning outlet, it is preferable that an airflow adjustment plate hanging in a direction away from the inclined wall portion is disposed on the inner surface of the inclined wall portion of the chamber.

  With such a configuration, the conditioned air that has flowed into the chamber from the air inlet is directed to the diffusion vane in a state of being evenly diffused by the air flow diffusion plate, so that the air conditioning outlet is in operation (air When the conditioned air flowing into the chamber from the inflow port is blown out from the blowout opening toward the indoor space), the noise of the blown airflow generated from the blowout opening can be suppressed. In addition, since the conditioned air flow is reliably guided toward the diffusion vane by the air flow diffusion plate, the conditioned air flow is reliably diffused and stability is improved.

  On the other hand, at the air-conditioning outlet, a movable blade that is rotatable about a support shaft parallel to the long side direction of the outlet opening is disposed in a region downstream of the diffusion vane in the chamber. Is desirable.

  With such a configuration, by rotating the movable blade around a support shaft parallel to the longitudinal direction of the blowout opening, the blowout direction is maintained while maintaining the air flow diffusion width according to the indoor layout and the air conditioning load. The degree of freedom in the layout design of the air-conditioning outlet can be improved.

  Furthermore, in the air-conditioning outlet, it is desirable that the blowout opening can be accommodated in a unit lattice area surrounded by the T-bar on the grid ceiling where the T-bar is arranged in a lattice.

  With such a configuration, the air-conditioning outlet is made compact to a size that allows the outlet opening to be accommodated in the unit lattice area, which is the minimum area surrounded by the T-bar forming the grid ceiling. Is reduced, transportability is improved, and workability is also improved. In addition, since the blowout opening is contained in the unit lattice area that is the minimum area surrounded by the T-bar, the design of the ceiling when viewed from the indoor side is not impaired. Furthermore, since the air-conditioning outlet can be arranged for each grid (unit grid area), the arrangement design of the air-conditioning outlet becomes easy, and it becomes easy to deal with an increase in partition by changing the layout.

  In addition, since the blowout opening does not straddle the T-bar, it is not necessary to change the shape, such as cutting out a part of the chamber located in the portion straddling the T-bar, as in the conventional line-type air-conditioning air outlet, The structure is simple. Furthermore, since it is not necessary to provide a notch in the chamber, the remaining wind speed of the conditioned air blown out from the vicinity of the lower portion of the air inlet of the blowout opening can be secured, and the air conditioning efficiency is not impaired.

  Next, in the air conditioning system of the present invention, any one of the air conditioning outlets described above is arranged on the ceiling on the perimeter side of the living room, and the longitudinal direction of the outlet opening of the air conditioning outlet and the window surface of the living room are parallel to each other. It arrange | positions so that it may make.

  With such a configuration, a conditioned air flow that blows out from the blowout opening of the chamber toward the living room and covers the entire window surface of the living room while being a smaller air conditioning blower than the conventional air conditioning blowout. Therefore, the air conditioning load on the perimeter side can be efficiently reduced. In addition, by reducing the size of the air-conditioning outlet, it is possible to reduce production materials and improve transportability and workability.

  According to the present invention, the noise of the blown airflow generated from the blowout opening during air-conditioning operation that secures a wide conditioned air diffusion area and increases due to the miniaturization while realizing the downsizing of the air conditioning blowout outlet. It is possible to provide an air conditioning outlet and an air conditioning system using the same, which can suppress the level to the minimum.

  Hereinafter, based on FIGS. 1-19, the air outlet 100 for air conditioning which is embodiment of this invention and an air conditioning system using the same are demonstrated.

  As shown in FIGS. 1 to 10, the air conditioning outlet 100 of the present embodiment blows a plurality of T-bars 2 in a lattice shape in order to blow out conditioned air supplied from an air conditioner (not shown) into the room. It is the air-conditioning equipment installed in the grid ceiling 1 formed by arrangement. The air conditioning outlet 100 includes a chamber 10 having a substantially trapezoidal shape in front view, an air inlet 11 provided in front of the chamber 10, and an outlet opening 12 provided in the bottom surface of the chamber 10. Yes. The air inlet 11 is provided with a short cylindrical neck 11a in a protruding shape.

  As shown in FIGS. 9 and 10, the blowout opening 12 can be accommodated in a unit lattice region surrounded by a T bar 2 that forms the grid ceiling 1. As shown in FIG. 8, a plurality of conditioned air diffused in the longitudinal direction L of the blowout opening 12 from the blowout opening 12 toward the indoor space R in a region upstream of the blowout opening 12 in the chamber 10. Diffusion vanes (first diffusion vane 21, second diffusion vane 22, and third diffusion vane 23) are provided.

  As shown in FIGS. 6 and 7, support shafts 16 a and 17 a parallel to the longitudinal direction L of the blowout opening 12 are provided in regions downstream of the first to third diffusion vanes 21, 22 and 23 in the chamber 10. A plurality of movable blades 16 and 17 that are rotatable about the center are provided at a predetermined distance. Each of the movable blades 16 and 17 is an elongated strip-like member, the side surface near each neck 11a has a smooth convex curved surface, the other side surface has a smooth concave curved surface, and the vertical cross-sectional shape is a substantially banana shape. I am doing.

Normally, as shown in FIG. 7, the blowing direction of the conditioned air flow blown out from the blowing opening 12 can be changed by rotating the movable blade 16 located on the front side (side close to the air inlet 11). . In the air-conditioning outlet 100 of the present embodiment, the depth dimension of the chamber 10 (dimension in the direction perpendicular to the longitudinal direction L) is set to 80 mm in order to accommodate the plurality of movable blades 16 and 17 in parallel. The depth dimension of the air-conditioning outlet is set wider than 65 mm. The depth dimension setting value of 80 mm is an example, and is not limited thereto.
It is desirable not to exceed mm.

  That is, when the movable blade 16 is set in an upright state (state indicated by a solid line), conditioned air is blown out from the blowout opening 12 in the downward direction (along the direction of the solid arrow V), and the movable blade 16 is inclined ( When set in a state indicated by a two-dot chain line), conditioned air is blown out from the blowout opening 12 in an oblique direction (along the direction of the two-dot chain line arrow T). In the air-conditioning outlet 100 of the present embodiment, the direction of the two-dot chain arrow T with respect to the direction of the solid arrow V is set to be 30 degrees, but is not limited to this.

  As shown in FIG. 6 and FIG. 7, a plurality of fall prevention devices 18 having an L-shaped cross section are fixed to the front and rear surface portions of the air conditioning outlet 100 near the bottom surface of the chamber 10. A hanger 19 is attached to a portion near the upper surface of the hanger. An air-conditioning outlet 100 is provided by engaging the suspension 19 with a suspension bolt (not shown) suspended from the building and sandwiching the upper edge 2a of the T-bar 2 between the fall prevention device 18 and the chamber 10. Is fixed to the grid ceiling 1.

  As shown in FIG. 8, the plurality of diffusion vanes 21, 22, and 23 are at a plurality of positions that are symmetrical with respect to the center line 10 c of the chamber 10 that passes through the center 12 c in the longitudinal direction L of the outlet opening 12 of the chamber 10. Further, they are arranged in a counter-inclined posture having a divergent shape symmetric with respect to the center line 10c.

  The inclination angle of the pair of first diffusion vanes 21 arranged closest to the center line 10 c is closer to the vertical than the inclination angle of the inclined wall portion 13 of the chamber 10, and the inclined wall is more inclined than the first diffusion vane 21. The inclination angles of the plurality of second diffusion vanes 22 arranged closer to the portion 13 are closer to the horizontal than the inclination angle of the inclined wall portion 13, and a pair of third third electrodes arranged at positions closest to the inclined wall portion 13. The inclination angle of the diffusion vane 23 is equal to the inclination angle of the inclined wall portion 13. In addition, the said equivalent shall be in the range of about ± 2 degrees.

  In the present embodiment, the inclination angle of the first diffusion vane 21 is 8 degrees, the inclination angle of the second diffusion vane 22 is 56 degrees, and the inclination angle of the third diffusion vane 23 with respect to the vertical direction (center line 10c). Is set to 33 degrees, but is not limited to these inclination angles.

  As shown in FIG. 8, airflow adjustment plates 14 are provided on the inner surfaces of the two inclined wall portions 13 that form a part of the chamber 10, respectively, depending on the direction away from the inclined wall portion 13. The pair of airflow adjustment plates 14 is provided on the inner surface of the inclined wall portion 13 near the blowout opening 12. The pair of airflow adjustment plates 14 are inclined in a direction in which they approach each other as they approach the blowout opening 12 (in a direction that approaches the center line 10c).

  In the present embodiment, as shown in FIG. 8, the inclination angle of the inclined wall portion 13 is set to 35 degrees and the inclination angle of the airflow adjusting plate 14 is set to 25 degrees with reference to the vertical direction (center line 10 c). However, it is not limited to these angles.

  As shown in FIGS. 9 and 10, the air-conditioning outlet 100 has a size that allows the outlet opening 12 to be accommodated in the unit lattice area U that is the minimum area surrounded by the T-bar 2 that forms the grid ceiling 1. It is compact. Therefore, compared with the conventional line-type outlet 200 for system ceiling shown in FIG. 20, materials are reduced, transportability is improved, and workability is also improved. Further, in the case of the air-conditioning outlet 100, since the outlet opening 12 is accommodated in the unit lattice area U that is the minimum area surrounded by the T bar 2, the design of the ceiling when viewed from the indoor side is not impaired. Furthermore, since the air conditioning outlet 100 can be arranged for each grid (unit grid area U), the layout design of the air conditioning outlet 100 is facilitated, and it is easy to cope with an increase in partition by changing the indoor layout. is there.

  In addition, a plurality of diffusion vanes (first to third diffusion vanes 21, 22, 23) provided in a region upstream of the blowout opening 12 in the chamber 10 allows the compact blowout opening 12 to enter the indoor space R. Since the conditioned air blown out toward the outside can be diffused over a wide range, a conventional line-type air-conditioning outlet and Equivalent performance can be obtained.

  Further, the movable blade 16 provided in the region downstream of the diffusion vanes (first to third diffusion vanes 21, 22, 23) in the chamber 10 is provided with a support shaft 16 a parallel to the longitudinal direction L of the blowout opening 12. By turning to the center, it is possible to adjust the air flow diffusion width and the blowing direction according to the indoor layout and the air conditioning load, so that the degree of freedom in the layout design of the air conditioning outlet 100 is improved.

  In the air-conditioning outlet 100, the first diffusion vane 21, the second diffusion vane 22, and the third diffusion vane 23 are disposed at the aforementioned inclination angles at the aforementioned inclination angles. The conditioned air that has flowed into the interior passes between the plurality of first diffusion vanes 21, second diffusion vanes 22, and third diffusion vanes 23 having different inclination angles. The diffusion region in the longitudinal direction L of the blowout opening 12 of the conditioned air flow blown out toward is greatly enlarged.

  As a result, the diffusion region of the conditioned air flow blown out from the blowout opening 12 of the chamber 10 toward the indoor space R can be secured up to about 2 to 4 times the size of the blowout opening 12 in the longitudinal direction L. In addition, while the size of the air-conditioning outlet 100 is smaller than that of the conventional air-conditioning outlet, the conventional line is secured while ensuring the remaining wind speed of the conditioned air blown out from the vicinity of the lower portion of the air inlet 11 of the outlet opening 12. Airflow diffusivity equivalent to that of a blower for type air conditioning can be realized.

  Further, in the air conditioning outlet 100, the air conditioning outlet 14 is provided on the inner surface of the inclined wall portion 13 of the chamber 10 so as to hang down in the direction away from the inclined wall portion 13, so that the air conditioning outlet 100 operates. The noise generated when the conditioned air flowing into the chamber 10 from the air inlet 11 is blown out from the blowout opening 12 toward the indoor space R can be suppressed. That is, the noise level of the blown airflow generated from the blowout opening during operation (during air-conditioned air blowout operation), which is increased due to the downsizing of the air conditioning blowout port 100 from the conventional product, is minimized. it can.

  Next, an air conditioning system 50 using the air conditioning outlet 100 will be described with reference to FIG. The air-conditioning system 50 of this embodiment has the air-conditioning outlet 100 shown in FIG. 1 in the grid ceiling 1 on the perimeter side of the living room R1 and the longitudinal direction L of the outlet opening 12 of the air-conditioning outlet 100 (see FIG. 1). And the window surface W of the living room R1 are arranged in parallel.

  If it is set as the air conditioning system 50, it will blow out from the blowing opening part 12 of the chamber 10 into the room R1, and it will be a window of the room R1, although it is the air conditioning outlet 100 smaller than the conventional air conditioning outlet. Since the conditioned air flow covering the entire surface W can be generated, the air conditioning load on the perimeter side can be efficiently reduced.

Next, an embodiment of the present invention will be described with reference to FIGS. In the present embodiment, the air-conditioning outlet 100 shown in FIG. 1 is installed on a grid ceiling 1 formed by arranging a plurality of T bars 2 in a lattice shape, and fed from an air conditioner (not shown). Conditioned air (air volume 300 m ³ / h) was blown out toward the indoor space R via the air conditioning outlet 100, and the airflow distribution was measured. 12 to 15 show the airflow distribution state during the cooling operation, and FIGS. 16 to 19 show the airflow distribution state during the heating operation.

  In the indoor space R, the ceiling height (distance from the floor surface 3 to the grid ceiling 1) is 2700 mm. Further, as preconditions for realizing a comfortable air-conditioning state in the indoor space R, the residual wind speed is 0.5 m / s and the generated noise is 30 dB (A) at the FL + 1200 point (position 1200 mm above the floor 3) during vertical blowing. Is set as a standard.

  12 and 13, the movable blade 16 (see FIG. 7) of the air conditioning outlet 100 is set in an upright state (state shown by a solid line), and is directed vertically downward (in FIG. 7). The airflow distribution state in the indoor space R when the cooling air is blown out (along the direction of the solid line arrow V) is shown. Curves 12w in FIG. 12 and FIG. 13 show portions where the final wind speed is 0.5 m / s in the cooling air flow blown out from the air conditioning outlet 100.

  When FIG. 12 is seen, the diffusion area | region of the longitudinal direction L (refer FIG. 4) of the blowing opening part 12 of the cooling airflow which blows off perpendicularly | vertically toward the indoor space R from the air-conditioning blower outlet 100 is the length of the blowing opening part 12 It can be seen that up to about 2 to 4 times the size of the direction L is secured. Moreover, when FIG. 13 is seen, it turns out that the spreading | diffusion area | region of the orthogonal | vertical direction of a cooling airflow has reached to the part of the grid ceiling 1 about 2400 mm (floor surface 3 to 300 mm).

  When the air conditioning outlet 100 according to the present embodiment is compared with a conventional size air conditioning outlet, the noise generated by the conventional size air conditioning outlet is lower than that of the air conditioning outlet 100, but the outlet airflow is divided. The air conditioning outlet 100 is compact in size and has a good airflow shape (in the vicinity of the lower portion of the air inlet 11 of the outlet 12) in contrast to the conventional size air conditioning outlet that cannot achieve efficient air conditioning. The remaining wind speed of the conditioned air blown out from the air can be secured), and the standard noise of 30 dB (A) can be cleared with respect to the generated noise.

  Next, in FIGS. 14 and 15, the movable blade 16 (see FIG. 7) of the air-conditioning outlet 100 is set in an inclined state (indicated by a two-dot chain line) and obliquely downward from the outlet opening 12. The airflow distribution state in the indoor space R when the cooling air is blown out (along the direction of the two-dot chain line arrow T) is shown. A curve 14w in FIGS. 14 and 15 shows a portion where the final wind speed is 0.5 m / s in the cooling air flow blown out from the air conditioning outlet 100.

  When FIG. 14 is seen, the diffusion area | region of the longitudinal direction L (refer FIG. 4) of the blowing opening part 12 of the cooling airflow which blows off diagonally toward the indoor space R from the air-conditioning blower outlet 100 is the length of the blowing opening part 12 It can be seen that up to about four times the size of the direction L is secured. Moreover, when FIG. 15 is seen, it turns out that the airflow of cooling air is blowing out from the air-conditioning blower outlet 100 at an angle of 30 degrees (30 degrees from the vertical direction). Therefore, even when an air conditioning system 50 as shown in FIG. 5 is constructed, it is possible to generate a cooling airflow that blows off from the air conditioning outlet 100 in an oblique direction by 30 degrees and covers the entire window surface W of the living room R1. Therefore, the air conditioning load on the perimeter side can be efficiently reduced.

  When the air conditioning outlet 100 in which the movable blade 16 (see FIG. 7) is set in an inclined state (indicated by a two-dot chain line) and a conventional air conditioning outlet, the conventional size air conditioning outlet is compared. Although the generated noise is lower than that of the air conditioning outlet 100, the air conditioning outlet 100 has a compact size compared to the conventional size air conditioning outlet where the blown airflow is divided and efficient air conditioning cannot be realized. The airflow shape is also good (the remaining wind speed of the conditioned air blown out from the vicinity of the lower part of the air inlet 11 of the blowout opening 12 can be secured), and the standard noise of 30 dB (A) can be cleared with respect to the generated noise.

  Next, FIG. 16 and FIG. 17 set the movable blade 16 (see FIG. 7) of the air-conditioning outlet 100 to an upright state (state indicated by a solid line), and vertically downward from the outlet opening 12 (FIG. 7 shows the air flow distribution state in the indoor space R when the heating air is blown out (along the direction of the solid line arrow V in FIG. 7). A curve 16w in FIGS. 16 and 17 shows a portion where the final wind speed is 0.5 m / s in the heating air flow blown out from the air-conditioning outlet 100.

  When FIG. 16 is seen, the diffusion area | region of the longitudinal direction L (refer FIG. 4) of the blowing opening part 12 of the heating airflow which blows off perpendicularly | vertically toward the indoor space R from the air-conditioning blower outlet 100 is the length of the blowing opening part 12 It can be seen that up to about four times the size of the direction L is secured. Moreover, when FIG. 17 is seen, it turns out that the spreading | diffusion area | region of the vertical direction of a heating air flow has reached the part about 1700 mm (floor surface 3 to 1000 mm) from the grid ceiling 1. FIG.

  When the air conditioning outlet 100 in which the movable blade 16 (see FIG. 7) is set in an upright state (shown by a solid line) is compared with the conventional size air conditioning outlet, the noise generated by the conventional size air conditioning outlet Is lower than the air-conditioning outlet 100, but the air-conditioning outlet 100 has a compact airflow shape while the air-conditioning outlet 100 is compact in size, whereas the air-conditioning outlet 100 is smaller than the conventional air-conditioning outlet. (The remaining wind speed of the conditioned air blown out from the vicinity of the lower part of the air inlet 11 of the blowout opening 12 can be ensured), and the generated noise can also satisfy the standard of 30 dB (A).

  Next, in FIGS. 18 and 19, the movable blade 16 (see FIG. 7) of the air-conditioning outlet 100 is set in an inclined state (a state indicated by a two-dot chain line) and obliquely downward from the outlet opening 12. The airflow distribution state in the indoor space R when heating air is blown out (along the direction of the two-dot chain line arrow T) is shown. A curve 18w in FIGS. 18 and 19 shows a portion where the final wind speed is 0.5 m / s in the heating air flow blown out from the air-conditioning outlet 100.

  Referring to FIG. 18, the diffusion region in the longitudinal direction L (see FIG. 4) of the outlet opening 12 of the heating air flow that is obliquely blown out from the air conditioning outlet 100 toward the indoor space R is the length of the outlet opening 12. It can be seen that up to about three times the size of the direction L is secured. Moreover, when FIG. 18 is seen, it turns out that the heating airflow blows off 30 degree | times (30 degree | times from a perpendicular direction) diagonally from the blower outlet 100 for an air conditioning. Furthermore, it can be seen from FIGS. 18 and 19 that the vertical diffusion region of the heating airflow reaches a portion of the grid ceiling 1 to about 1300 mm (floor surface 3 to 1400 mm).

  When the air conditioning outlet 100 in which the movable blade 16 (see FIG. 7) is set in an inclined state (indicated by a two-dot chain line) and a conventional air conditioning outlet, the conventional size air conditioning outlet is compared. Although the generated noise is lower than that of the air conditioning outlet 100, the air conditioning outlet 100 has a compact size compared to the conventional size air conditioning outlet where the blown airflow is divided and efficient air conditioning cannot be realized. The airflow shape is also good (the remaining wind speed of the conditioned air blown out from the vicinity of the lower part of the air inlet 11 of the blowout opening 12 can be secured), and the standard noise of 30 dB (A) can be cleared with respect to the generated noise.
