DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting a plurality of use-side units (housings) in a building such as a building.

[0002]

2. Description of the Related Art In general, a plurality of use side units are connected to each other in a building such as a building, and a ventilation duct is connected to each use side unit. These units are divided into an interior part and a perimeter part in the building. There is known an air conditioner in which cold air or warm air can be individually blown to each part (for example, Japanese Patent Application Laid-Open No. 4-24441).

In this type, a suction duct is connected to the use-side unit that has been connected to each other, and air outside the building is drawn into the use-side unit from the suction duct, and the air is heat-exchanged. It is designed to be sent out to the interior or perimeter through a duct.

FIGS. 3 and 4 are plan views of the inside of a building, respectively.
It is installed in the space 30 between the room 20. One usage unit 100 is a perimeter unit for air-conditioning the perimeter unit, and the other usage unit 200 is an interior unit for air-conditioning the interior unit.

[0005]

In the above-mentioned space 30, when the two use side units 100 and 200 are connected, either the use side unit for the interior unit or the use unit for the perimeter unit is placed at any of the left and right positions. It is not decided. For example, in the examples of FIGS. 3 and 4, the positions of the use side units 100 and 200 are reversed because the positions of the air ducts 300 and 400 are reversed.

When the positions of the use-side units 100 and 200 are reversed, the positions of the openings for connecting the use-side units 100 and 200 are different from each other. There is a problem that the same use side unit cannot be used in FIG. 3 and FIG.

Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art, and to easily connect the use-side units even if the connection directions of the use-side units are different from each other. Is to provide.

[0008]

Means for Solving the Problems To achieve the above object, the present invention relates to a use side unit of an air conditioner, in which a plurality of housings to which suction ducts and / or ventilation ducts are connected are arranged and connected to each other. before on both side surfaces of the housing
The same size as that of the suction ducts can be connected
Openings, and these openings connect each other's use side units.
It also doubles as an opening for connection, and
When the suction port is connected to form a suction passage in this connection part,
A connecting flange is interposed between the openings of the
It is characterized in that it is configured to be connected by connecting .

[0009]

According to the present invention, since openings are provided on both side surfaces of each of the use side units for both connecting the unit and connecting the suction duct, the positions of the use side units adjacent to each other are reversed. Even if it is changed, the openings can be opened in any direction, so that both can be easily connected.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an air conditioner according to an embodiment of the present invention;

Referring to FIG. 5, if this air conditioner is used, the perimeter unit 1 and the interior unit 3 in the building can be individually heated or cooled. For example, in the middle period or the like, when the outside air temperature is low, warm air can be sent to the perimeter unit 1 and cool air can be sent to the interior unit 3 where OA equipment and the like are densely packed. 3 and 4 show plan views inside the building. As is apparent from these figures, the air conditioner is provided with a utilization unit 100 for the perimeter unit.
And a use side unit 200 for the interior part,
These use-side units 100 and 200 are normally located in the corridor 10.
It is installed in the space 30 between the room 20.

The use side units 100 and 200 will be described. As shown in FIG. 6, a use side heat exchanger 5 is provided in the center of the inside, and a blower 7 is provided above the use side heat exchanger 5.
Is provided. Then, a heat source side unit (not shown) is connected to the use side heat exchanger 5 via a refrigerant pipe, thereby forming a refrigeration cycle. The air outside the building, such as a building, passes through the suction duct to the use side unit 10.
After being introduced into the insides 0 and 200 and exchanging heat there, they are sent out to the room 20 through the ventilation ducts 300 and 400, respectively.

After the two usage units 100 and 200 are installed in the space 30, they are connected to each other there.

By the way, as is clear from FIGS. 3 and 4, when the positions of the air ducts 300 and 400 are reversed, the positions of the use side units 100 and 200 are reversed. However, according to the present embodiment, even if the positions of the use side units are reversed, both can be easily connected.

That is, as shown in FIG. 1, openings 51, 52, 53, and 54 having the same size as each other are formed on both lower side surfaces of the use-side units 100 and 200, respectively.
The openings 51, 52, 53, and 54 also serve as an opening for connecting the use side units 100 and 200 to each other and an opening for connecting the suction duct 500. In the example shown in FIG. Are used as openings for connecting the suction duct 500, and the openings 52 and 53 are used as openings for connecting the use side units 100 and 200 to each other. When the positions of the use-side units 100 and 200 are reversed, the openings 51 and 54 serve as openings for connecting the use-side units 100 and 200 with each other, and the openings 52 and 54 also serve as openings. Suction duct 50
It is used as an opening to connect 0.

Opening 5 of user-side units 100 and 200
Between the 2, 53, connecting flange 61 is interposed, this
The connecting unit of the user side unit 200 to the user side unit
A suction passage towards 100 is formed. The opening 54
A connection flange 63 is interposed between the suction duct 500 and the suction duct 500 (FIG. 1). These flanges 61 and 63 have a structure that can be attached to any of the openings 51, 52, 53 and 54.

At this time, a refrigerant pipe 70 (see FIG. 2) from a heat source side unit (not shown) is led to the opening 51, and each of the refrigerant pipes 70 has a use side unit 10 (see FIG. 2).
0,200 are connected to the use side heat exchanger 5. A cover 65 for closing is attached to the opening 51. 5
Reference numeral 7 denotes a header for connecting the above-mentioned refrigerant pipe.

Further, openings 55 and 56 for connecting ventilation ducts are formed in the ceiling surfaces of the use side units 100 and 200, respectively, and the ventilation ducts 300 and 4 are respectively provided in the openings 55 and 56.
00 is connected.

As described above, according to the present embodiment,
As shown in FIG. 3 and FIG.
Even when the position of 00 is reversed, the flanges 61, 63
The user-side unit 10 is reversed by simply changing the
0, 200 can be easily connected.

[0020]

As is apparent from the above description, according to the present invention, even if the positions of the user units to be connected are reversed, these reversed user units can be easily connected. Can be.
