Description

  The present invention relates to an air supply chamber for supplying air into a room from a small air conditioner such as a packaged air conditioner.

  Conventionally, when a small air conditioner such as a packaged air conditioner (PAC) or a fan coil unit is disposed on an exposed ceiling of a store or the like, for example, as shown in FIG. 127, cold air and warm air are diffused over a wide area of the air-conditioning area. Specifically, first, the PAC is suspended from the exposed ceiling, and the air supply chamber 110 is connected to the downstream side. And the spiral ducts 121-127 are constructed from the air supply chamber 110 to a predetermined position in the air conditioning area. And the blower outlets 131-137 are connected to the front-end | tip of the spiral ducts 121-127. In this way, the airflows f11 to f17 are formed by the outlets 131 to 137.

Thus, since it is necessary to construct the spiral ducts 121 to 127 in a wide area in the room in order to diffuse the cold air and the warm air, the spiral ducts 121 to 127 become long and the construction cost increases. Specifically, for example, in order to disperse the supply air in an area of 10 m ² , the total length of the spiral ducts 121 to 127 (250Φ) is several kilometers. In addition, since the spiral ducts 121 to 127 are long, it is necessary to construct a heat insulating material on the outer periphery of the spiral ducts 121 to 127 in order to keep cool air and warm air in the flow path, which increases costs. Furthermore, the positions of the air outlets 131 to 137 are fixed by the installed spiral ducts 121 to 127. For this reason, for example, even if the layout is changed due to the renovation of the tenant, it is difficult to change the positions of the air outlets 131 to 137, and the air conditioning equipment needs to be repaired.

  By the way, the technique regarding the air distribution apparatus for indoor air conditioning which distributes adjustment air to the important point of a room without using a duct is known (for example, refer patent document 1). Moreover, the technique regarding the ventilation unit for large spaces which can switch the blowing direction from a blower outlet is known (for example, refer patent document 2).

Japanese Utility Model Publication No. 60-015048 JP 2007-192530 A
