Description

GRILL TYPE INDUCING DIFFUSER [0002]

The present invention relates to a grill-type attracting air outlet.

There is a low-temperature ventilation and air-conditioning system in which air supplied from an air conditioner is cooled to a lower temperature than usual and the air flow rate is reduced to supply air from an air outlet provided in an air-

Japanese Patent Application Laid-Open No. 2001-153448

In such a low-temperature ventilation air conditioning system, when a conventional grill-type air outlet is used, there is a problem that cold draft and condensation occur due to the low temperature of the supplied air.

In order to solve the above problems, the present invention has a main body for entraining air in an air-conditioned space to the air supplied from the outside and extracting the mixed air into the air-to-air space, A mixed blow-out air passage for blowing the mixed air of the feed air and the attracting air into the air-conditioned space; A plurality of inlet ports communicating with the mixed take-out air passage are provided for attracting the drawn-in air, and a plurality of the downward-flowing downwind-side inlet ports are arranged in the upwind- And is arranged so as to be blown in succession into the inlet port.

According to the invention of claim 1,

(1) Since the temperature difference between the air taken out from the mixed take-out air passage into the air-conditioned space and the air to be air-conditioned space is reduced according to the reheating by the air- It is possible to prevent temperature variations, condensation, and the like of the cold draft and the air-conditioning space caused by being taken out as it is, thereby improving the comfort.

(2) Since the low-temperature supply air and the attracting air of higher temperature are taken out from the inside of the main body, condensation can be prevented from occurring on the wind side near the air blow-out port. Therefore, it is unnecessary to heat the inlet port and the mixed blow-out air passage, thereby reducing the heat insulating treatment range and making it easy to manufacture.

(3) Since the attracted air can be gradually increased in the plurality of attracting holes serving as the air outlet, it is possible to secure a large amount of the attracted air (mixing ratio) with respect to the supplied air volume. Therefore, the blow-out air volume of the mixed air can be increased, and the diffusibility is improved and the temperature fluctuation is eliminated.

(4) Since the air outlet and the inlet port can be used together, the manufacturing is simplified, and the production is easy and cheap.

(5) It is possible to arbitrarily change the manned air volume by increasing or decreasing the number of attraction points, and by adjusting the attracting amount of air in the air-conditioned space, it is possible to select the optimum mixed air take- .

According to the invention of claim 2,

(1) Since two attraction plates can be formed by one partitioning member, the structure is simplified, and the production becomes easy.

(2) Since the wind speed can be increased by reducing the opening toward the wind-blowing side, the attracting performance is not lowered and the attracting amount can be stably secured.

Fig. 1 is a view of the grill-type induction blow-out port viewed from the take-out opening side.
2 is a sectional view taken along the line AA in Fig.
Fig. 3 is a view seen from the direction B in Fig.

1 to 3 show an embodiment of the grill-type attracting and delivering opening of the present invention. In this embodiment, the supply side of the supply air is referred to as "wind blowing side ", and the blow-out side of the mixed air is referred to as" The grill-type manhole outlet port is provided with a main body 1 for introducing the air in the air-conditioned space S to the air-to-air space S from the outside, and mixing the air in the air- The air-conditioning space (S) is a space such as a room or hall of an office building, a hospital, a hotel, or the like. A grill type manhole outlet port is provided on a wall surface or a ceiling of the air-conditioned space S. In the grill type manhole outlet port, air for conditioning or the like is supplied from a not shown air conditioner through a duct or the like. In each figure, thick arrows of dotted lines indicate the wind direction.

The main body 1 is provided with an air jetting port 2 for jetting the supply air, an attracting air passage 3 for drawing the attracting air from the air-conditioned space S, and a mixed air of the supply air and the attracting air, And a plurality of inlet ports 5 for connecting the inlet and outlet air paths 3 and 4 to the inlet and outlet air passages 4 and 5 and a plurality of inlet ports 5, And the attracted mixed air is sequentially blown into the wind-driven entrance port 5b at the wind-driven inlet port 5a.

The air outlet 2 is linearly formed along the opposite sides of the elongated outlet opening 11 of the main body 1. [ The connecting portion between the attracting air passage 3 and the mixed take-out air passage 4 is partitioned by one partitioning member 6 so that two attracting holes 5 are linearly formed along the air ejecting opening 2. The air outlet 2 and the inlet 5 are formed so as to reduce the cross-sectional area of the passage so that the opening becomes smaller toward the windward side to increase the wind speed.

The main body 1 has an outer wall body 8 and an inner wall body 9 each having an opened end at both ends and a partition member 6 and a plurality of fans 10. The wall 9 is provided inside the outer wall member 8 at a predetermined interval. An induction air passage 3 is formed on the inner surface of the outer wall member 8 and the outer wall surface of the inner wall body 9 to form a mixing takeout air passage 4 on the inner surface of the inner wall body 9. Further, the composition and structure of the mixed takeout air passage 4 and the attracting air passage 3 can be changed, and the present invention is not limited to the embodiments described in the drawings.

The supply air sent to the main body 1 passes through the air blow-off port 2 and is blown toward the blow-in port 5a. At this time, the air gap between the air blowing port 2 and the inlet port 5a on the blowing side becomes a negative pressure, and the air in the air-to-air space S is attracted through the air blowing path 3. The attracted air is mixed with the supplied air to become mixed air having increased air flow, and the attracted air is blown toward the attracting port 5b on the wind-blowing side while increasing the wind speed in the narrow channel in front of the attracting port 5a. Accordingly, the space between the inlet port 5a on the wind-blowing side and the inlet port 5a on the wind-blowing side becomes negative and the air in the air-conditioning space S is attracted through the manned air passage 3, Resulting in increased mixed air. In this way, since the attracted mixed air is blown in succession to the wind-driven inlet 5 at the wind-driven inlet port 5, the mixed-air blow-out air flow rate Can be increased.

The mixed air passes through the mixed take-out air passage (4), diffuses toward the air-conditioned space (S) and is taken out. For example, in the cooling inlet 5 and the mixed take-out air passage 4, low-temperature supply air at 13 ° C is reheated by mixing induction air at room temperature of 27 ° C, which is higher in temperature, so no condensation occurs. Further, the supply air is set to be higher in temperature than the dew point temperature of the air-conditioned space S and lower in the absolute humidity at the time of manhour mixing, but the change is possible.

Further, the present invention is not limited to the above-described embodiments, and design changes can be made without departing from the gist of the present invention. For example, it is also possible to increase or decrease the number of the attraction ports 5 and the manned airways 3.
