  Thus, the radiation unit helps to create a comfortable space, but there is a problem that the structure is complicated and the cost is high.

In order to solve the above-mentioned problems, the present invention has a rectangular flat shape and a first chamber portion through which air for air-conditioning flows in the long side direction thereof, and a rectangular flat shape and the first chamber portion in the flat direction. A second chamber portion provided adjacent to each other so as to overlap , wherein the first chamber portion is in contact with the second chamber portion and emits the air-conditioning air to the second chamber portion, The second chamber section includes a second ventilation section that contacts the air-conditioned space and outputs the air-conditioned air to the air-conditioned space, and a heat storage section, and is parallel to the short side of the first chamber section. the airflow passage cross-sectional area of Do the conditioned air, the long side sequentially narrowed toward the downstream side in the direction a and the windward side of the air-conditioning air, said first vent is the second from the first chamber portion First through-hole for discharging the air-conditioning air to the chamber The second ventilation part includes a plurality of second through holes that let out the air for air conditioning from the second chamber part to the air-conditioned space, and the heat storage part is the first of the first ventilation part. The second air-conditioning air is arranged so as to be spaced apart from each other along the direction of flow of the air-conditioning air passing through the through-holes, and the air-conditioning air is allowed to flow in a rectifying manner while being diffused and diffused into the gap. The air is discharged from the second through hole of the ventilation part to the air-conditioned space, and heat of the air-conditioning air is stored and transferred to the second ventilation part to be transmitted from the second through hole and the second ventilation part. The main feature is the provision of a plate that radiates to the air-conditioned space .

According to the first aspect of the present invention, since the first chamber portion is gradually narrowed from the windward side toward the leeward side, the wind speed of the air for air conditioning increases from the windward side toward the leeward side, Air-conditioning air can be spread over the entire space of the second chamber portion. Therefore, it is possible to equalize the discharge and radiation of air-conditioning air to the air-conditioned space, and to perform comfortable air-conditioning without a draft feeling and temperature unevenness . Since it is a simple structure in which the first chamber portion is narrowed and a through hole is formed in the second chamber portion, the cost can be reduced, and the weight and weight can be reduced while increasing the rigidity, so that construction and maintenance are facilitated . The thermal storage unit, can be also used as heat storage and rectification of the air-conditioning air, heat radiation force be reduced to ensure improved airflow unevenness and temperature unevenness. Because the total body of flat shape can also be easily installed in narrow bosom ceilings, construction and maintenance becomes easier.
According to invention of Claim 2, since a 2nd ventilation part is a corrugated sheet shape, a radiation area can be expanded and a radiation capability can be improved further.

It is the perspective view which looked at the pneumatic type radiation unit of the present invention from the bottom side. It is a bottom view of FIG. Example 1 It is AA sectional drawing of FIG. It is BB sectional drawing of FIG. It is CC sectional drawing of FIG. It is a bottom view of another pneumatic radiation unit. (Example 2) It is DD sectional drawing of FIG.

  1 to 5 show the pneumatic radiation unit of the present invention. The pneumatic radiating unit includes a first chamber portion 1 through which air-conditioning air flows, a second chamber portion 2 that radiates air-conditioning air that has entered from the first chamber portion 1 to the air-conditioned space S such as a room, It has. The thick dotted arrows in each figure indicate the direction in which air-conditioning air flows.

  The first chamber section 1 includes an air inlet section 3 into which air-conditioning air enters, a flat plate-shaped first ventilation section 4 that comes into contact with the second chamber section 2 and emits air-conditioning air into the internal space of the second chamber section 2, It has. The second chamber part 2 is attached to the flat plate-shaped second ventilation part 5 that comes into contact with the air-conditioned space S and emits air-conditioned air to the air-conditioned space S, the heat storage part 6, the second ventilation part 5, and the heat storage part 6. And a frame 7 with a flange.

  A pneumatic radiation unit is installed on the ceiling or the like of the air-conditioned space S so that the second ventilation portion 5 faces the air-conditioned space S. The air inlet 3 is connected to an air outlet of an air conditioner (not shown) via a duct 11, and air for air conditioning is supplied from the air conditioner to the internal space of the first chamber 1.

A first chamber portion 1 having a rectangular flat shape in which air for air-conditioning flows in the long side direction thereof and a rectangular flat second chamber portion are provided adjacent to each other so as to overlap in the flat direction. In the illustrated example, the first chamber portion 1 and the second chamber portion 2 are rectangular flat shapes, but they can be freely changed to various flat shapes such as elongated, square, and round shapes.

The air-flow passage cross-sectional area of the air-conditioning air parallel to the short side of the first chamber section 1 (the area of the cross-section parallel to BB in FIG. 2) is the long-side direction from the leeward side to the leeward side of the air-conditioning air. Set to narrow gradually. In the illustrated example, both the outer surface and the inner surface of the first chamber portion 1 are inclined and narrowed, but only the inner surface may be inclined and narrowed without tilting the outer surface.

  The first ventilation part 4 includes a first through hole 8 that emits air for air conditioning from the first chamber part 1 to the second chamber part 2. In the illustrated example, the partition between the first through-hole 8 and the first through-hole 8 is also used as a rib to increase the rigidity. The 2nd ventilation part 5 is provided with many 2nd through-holes 9 which let the air for an air conditioning from the 2nd chamber part 2 to the to-be-conditioned space S so that it may become a predetermined opening ratio. The aperture ratio of the second ventilation part 5 is set to 70 to 80%, for example. The first through hole 8 and the second through hole 9 can be freely changed to various shapes such as a perfect circle, an ellipse, a long hole, and a narrow groove, and can be changed in number and size.

  The heat storage unit 6 stores the heat of the air-conditioning air to radiate each other so that there is a gap along the direction in which the air-conditioning air flows through the first through hole 8 of the first ventilation unit 4. Arranged at a distance. The plate 10 and the second ventilation part 5 use aluminum or the like having high heat transfer and thermal emissivity.

  The air-conditioning air passes through the plate 10 in a rectifying manner while being shunted and diffused, and exits from the second through hole 9 of the second ventilation portion 5 to the air-conditioned space S. The heat of the air for air conditioning is transferred to the plate 10 and the second ventilation part 5, and is radiated from the second through hole 9 and the second ventilation part 5 to the air-conditioned space S.

  6 and 7 show the second chamber portion 2 of the first embodiment in which the second ventilation portion 5 having a large number of second through holes 9 is formed in a corrugated plate shape. In addition, change of the inclination angle and height of a corrugated plate shape, and the number of unevenness | corrugations is free. The other configuration is the same as that of the embodiment of FIG.
