2. Description of the Related Art Conventionally, a flexible duct for connecting a ceiling-suspended air conditioner housed in a ceiling and a rectangular or line type air outlet is provided on the outer periphery of a flexible duct formed of a zinc-plated iron plate. Since it is formed by applying a heat insulating material or formed of a hard glass wool plate having heat insulating properties, its length cannot be adjusted. For this reason, it is necessary to make a flexible duct in accordance with the distance and position between the ceiling-suspended air conditioner and the outlet frame, which are different for each construction site.

For this reason, the position of the opening of the light ceiling is determined by carrying out the light ceiling work, and an opening for mounting the air outlet frame is provided on a board stretched over the light sky, and the air outlet frame is provided in the opening. After installation, a situation arises in which a flexible duct is formed in accordance with the distance and position between the ceiling-suspended air conditioner and the outlet frame which have been suspended in advance, and the flexible duct connects the two. In other words, the work associated with the ceiling-suspended air-conditioning equipment must be interrupted by the light sky work, and the light-weight work associated with the ceiling-suspended air-conditioning equipment becomes congested, and during one construction period, the other work is interrupted. The construction period must be prolonged. An object of the present invention is to provide a ceiling-suspended air-conditioning facility free of such a problem and a method of constructing the same.

Reference numeral 3 denotes an extendable flexible duct for connecting the frame-shaped portion 2b of the outlet mounting frame 2 to the horizontally elongated outlet 1e provided in the ceiling-mounted air conditioner 1, and the flexible duct. Reference numeral 3 is configured to have a sectional shape substantially similar to the frame-shaped portion 2b. The conventional flexible duct has a circular cross section, whereas the outlet mounting frame 2 and the like are rectangular. If the circular flexible duct is used as it is, the flow changes suddenly and turbulent flow occurs. Therefore, by making the cross-sectional shape of the flexible duct 3 substantially similar to the frame-shaped portion 2b, it is possible to prevent a problem due to the disturbance of the air flow from the flexible duct 3 to the outlet 1e, for example, the disturbance of the air flow. As far as possible, the noise and pressure loss associated with turbulence in the air flow can be eliminated. This flexible duct 3 is shown in FIG.
As shown in FIG. 1, a strip-shaped nonwoven fabric is wound around the outer periphery of a steel wire while being formed in a spring shape (a) by a winding machine X, and the nonwoven fabric is sequentially adhered to the cylindrical body (b) (fan coil 1). In the case where the width of the air supply port is 440 mm and the height is 130 mm, a cylindrical body having a diameter of 400 mm is manufactured, and this is formed as shown in FIG. To
The outer periphery of the cylindrical body (b) is brought into contact with a ruler plate Y, and the cylindrical body (b) is pressed against the ruler plate Y from the inside to form a square tube body (c) having a rectangular cross section. A glass wool (d) is wound around the outer periphery of the rectangular tube (c), and a vinyl chloride film tube (e) is further covered around the outer periphery thereof. It is folded into the inside of (c) and stapled, and then a duct tape is wound around the outer periphery of both ends to produce a square shape having ears 3a at both ends.

However, the material and the like of the flexible duct 3 are not necessarily limited thereto, and the flexible duct 3 has heat insulation properties and can be configured to be able to expand and contract as a whole. 1
e, the sectional shape of the flexible duct 3 is not limited to a rectangle, and may be an ellipse or an ellipse. Any shape may be used as long as the flow of cold air or warm air flowing inside does not change suddenly. Before suspending the flexible duct 3 from the ceiling-suspended air conditioner 1 on the ceiling slab, a connection pipe 3b is inserted into one ear 3a of the flexible duct 3, and the ceiling-suspended air conditioner is attached to the connection pipe 3b. After the air outlet 1e of the air conditioner 1 is fitted, the air outlet 1e of the ceiling-suspended air conditioner 1 is tightened and fixed with screws (not shown) or the like.
In the above-described embodiment, a fan coil unit is used as the ceiling-suspended air conditioner 1. However, the ceiling-suspended air conditioner 1 is not limited to this, and includes a package air conditioner, a total heat exchanger, and the like. It is needless to say that it is good.
The connection pipe 3b is connected to the outlet 1 of the ceiling-suspended air conditioner 1.
This can be omitted by increasing e.

According to the ceiling-suspended air conditioner of the first aspect of the present invention, even if the distance and the positional relationship between the outlet mounting frame and the ceiling-suspended air conditioner differ from site to site, Since the flexible duct has flexibility in the length direction, the ceiling-suspended air conditioner and the outlet mounting frame can be connected with a flexible duct prepared in advance, making construction extremely simple. The installation work of the suspension type air conditioner can be greatly shortened, and it is not necessary to prepare flexible ducts having different flexible duct lengths at each construction site, thereby reducing costs. Moreover, since the flexible duct has a cross-sectional shape substantially similar to that of the air outlet, the air flow does not change as much as possible from the flexible duct to the air outlet, thereby reducing pressure loss and noise accompanying the air flow. The occurrence can be suppressed.
