Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air system in a building, and more particularly to an individual ventilation type air conditioner suitable for a room provided with a partition wall.

Conventional technology Generally, in the office air conditioning system, a space behind the ceiling is formed between the floor slab on the upper floor and the ceiling plate, and a supply duct leading to the air conditioner is installed in this space above the ceiling and installed on the ceiling plate. Air is evenly sent into the entire room from a plurality of air outlets.

However, recently, machines with large heat generation such as OA equipment have become scattered in the room, and partition walls (partitions) have been installed to block the noise generated by the equipment. This made it difficult to achieve uniform air conditioning. At the same time, there has been a demand for a personal air conditioning system that performs air conditioning suitable for the sensible temperature of an individual.

Japanese Unexamined Patent Publication No. 61-159034 “floor installation unit” is configured so that air can be supplied only to a desired place by using an air supply passage provided under the floor. It is necessary to cover the whole with a thick flat plate to form a strong double floor, and there is a drawback that the cost is remarkably high especially in a building with a large floor area.

No. 62-63637 "Partition wall with duct" and No. 62
In −67016 “Indoor structure of office buildings,” a ventilation duct is attached to the partition wall, and a flexible duct is connected to the ventilation duct in communication with the ventilation duct, but the partition wall and the ventilation duct are integrated. However, there are restrictions on the degree of freedom when changing the layout of the room.
Further, since the chamber-in-ceiling is formed between the floor slab on the upper floor and the ceiling plate, there is a drawback that the vertical dimension when connecting the flexible duct is limited.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The object of the present invention is that the number and arrangement of air outlets can be freely selected, and the degree of freedom in changing the indoor layout is large and can be applied to existing buildings at low cost To provide a blower type air conditioner.

Means for Solving the Problem and Its Action The above-mentioned object of the present invention is to provide a horizontal duct installed on the lower surface of the floor slab forming the ceiling surface and a plurality of air ducts connected to the horizontal duct for air communication therein. A branch box and an individual blower column connected from the branch box through a flexible duct are provided. The individual blower column body extends in the vertical direction and has a horizontal cross-sectional shape of an isosceles triangle. This is achieved by an individual air blower type air conditioner having a hollow frame, an air duct extending vertically inside the frame, and an air outlet provided on either surface of the frame.

Based on such a configuration, according to the present invention, since air is supplied from the horizontal duct and the branch box without forming the ceiling chamber, the ceiling plate becomes unnecessary and the cost is reduced. Air is sent from the branch box through the flexible duct to the individual blower columns, so it is easy to change the layout of the room, and since there is no ceiling plate, the vertical dimension when connecting the flexible duct can be large. There is an advantage. The individual blower column has a hollow frame whose horizontal cross section is approximately an isosceles triangle, so it can be attached closely to the end face of the partition wall. It is possible to form a regular polygonal columnar body by combining the six to six to enhance the self-supporting property. By passing various electric wirings and communication cables in addition to air-conditioning ducts inside the pillars, it becomes possible to convert the room of an existing building into a so-called intelligent office.

Other features and advantages of the present invention will be apparent from the following description with reference to the embodiments of the accompanying drawings.

Embodiment FIG. 1 shows an individual ventilation type air conditioner according to a preferred embodiment of the present invention, in which a floor slab 10 on an upper floor forms a ceiling surface, and a horizontal duct 12 is provided on a lower surface of the floor slab 10 as a hanging fitting. It is fixed (not shown) or the like. At the inner bottom of the horizontal duct 12, there are wirings 14 for high and low electric power, and cables 16 for communication.
Etc. are installed, and a heat insulating material is attached to the inner wall. On both sides of the horizontal duct 12, there are branch boxes via connecting pipes 18.
20 are connected to each other, and the branch boxes 20 are attached to the lower surface of the floor slab 10 by suspending metal fittings (not shown) or the like. Similarly, a wiring storage pipe 22 extends from the horizontal duct 12 adjacent to the connection pipe 18, and its end is connected to the branch box 20. A plurality of flexible ducts 24 hang down from the lower surface of the branch box 20, and the lower ends thereof are connected to the upper ends of the individual air-blowing pillars 26 and are in air communication inside. Further, from the wiring storage pipe 22 connected to the branch box 20 to various cords 28
Hangs down and is inserted inside from the upper end of the column 26. The end edge of the partition wall 30 abuts on the side surface of the individual blower pillar 26,
A personal work space 40 for accommodating various OA equipment is formed.

FIG. 2 shows a preferred embodiment of the individual air-blowing column 26, which is a hollow frame 50 having a substantially isosceles triangular horizontal cross section.
Extends vertically, an air duct 52 extends vertically inside the frame, and an air outlet 54 is arranged on the front surface of the frame. At the upper end of the air duct 52, a socket 56 for connecting the flexible duct 24 (Fig. 1) is provided. Wirings 14 and communication cables 16 extend inside the frame adjacent to the air duct 52, the wirings 14 are connected to an outlet 58 and an electric box 60, and the cables 16 are connected to a communication cable connector 62. There is. Frame 50
Is an isosceles triangle with an apex angle of 90 degrees and an open bottom surface. A rectangular parallelepiped column can be constructed by combining four columns.

As a modified example according to the present invention, it is also possible to provide an air intake port on any surface of the hollow frame 50 and arrange an air duct for return air inside the pillar body to add the flexible duct 24. Further, by providing the branch box 20 with an air outlet or an air inlet, it is possible to easily switch the individual air conditioning to the general air conditioning system.

Further, one flexible duct 24 may be provided, and an air distribution device may be provided above the individual blower column 26.

EFFECTS OF THE INVENTION As described in detail above, according to the individual ventilation type air conditioner of the present invention, the following advantages can be obtained.

1) The ceiling plate is not required, the cost is reduced, and the amount of air-conditioning air to be blown is small.

2) The degree of freedom when changing the layout of the room is large, and the work can be easily performed.

3) A regular polygonal pillar can be obtained by combining a plurality of pillars, which facilitates the design process and enhances the independence of the pillar to facilitate the installation work.

4) The individual air conditioning system can be easily switched to the general air conditioning system.

5) It can be applied to existing buildings.
