DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower of an air conditioning system, and more particularly, to a blower of an air conditioning system for supplying air for cooling and heating to a room through a duct, the structure including walls and beams. The present invention relates to a blower that can be installed close to an object and can be installed in a further space-saving manner.

2. Description of the Related Art As is well known, an air conditioning system such as a central heating system is provided with a heat exchange device and a control system.
This is a system that supplies air for cooling and heating from one main facility to a plurality of living rooms. In such an air-conditioning system, air for cooling and heating is supplied to each living room by a duct, but a blowing device is installed near the outlet of each living room in order to adjust the amount of air and the temperature for each living room. In small-scale air conditioning systems installed in detached buildings,
Air for cooling and heating is supplied to each room via at least one air blower attached to the main equipment.

FIG. 2 is a view showing a conventional blower.
(A) is a plan view, and (b) is a side view. FIG.
The blower shown in (1) comprises a blower fan (2) to which a heat medium is supplied from a heat exchange device of a main facility and a coil unit (3) for heat exchange accommodated in a box-shaped casing (1).
A suction duct (4) for taking in air is connected to a rear end of the casing (1), and a blow duct (5) for sending out heat-exchanged air is connected to a front end of the casing (1). .

[0004]

By the way, an air blower as shown in FIG. 2 is usually housed in the ceiling or the like. However, depending on the layout of the ceiling or the like, the rear end side of the casing (1) is, for example, a wall (6). ), The suction duct (4) needs to be bent and installed. In this case, the installation area of the blower needs to be larger than the area occupied by the casing (1) itself, and it may be difficult to install the blower at a predetermined position. That is, even if it is installed as close to the wall (6) as possible, the installation distance (L) from the wall (6) to the front end of the casing (1) is at least the entire length of the casing (1). Only the length including the bending radius is required.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a blower of an air-conditioning system that can be installed close to a structure such as a wall or a beam and can be installed in a further space-saving manner. It is in.

[0006]

According to the present invention, there is provided an air conditioner for an air conditioning system for supplying air for cooling and heating to a room through a duct, comprising: And a box-shaped casing accommodating a coil unit for heat exchange, a blower duct connected to a front end of the casing and sending out heat-exchanged air, and a suction duct that takes in air into the casing, The suction duct is connected to a side surface of the casing.

That is, in the above-described blower, the structure in which the suction duct is connected to the side surface of the casing has a structure in which air is taken directly into the casing from a direction perpendicular to the direction in which the blower duct is sent out without bending the suction duct. I can do it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a blower of an air conditioning system according to the present invention will be described with reference to the drawings. FIG.
It is a diagram showing a blower of the air conditioning system according to the present invention,
(A) is a plan view, and (b) is a side view. Hereinafter, in the description of the embodiment, the blower of the air conditioning system is abbreviated as “blower”.

As shown in FIG. 1, the blower of the present invention is a blower of an air conditioning system for supplying air for cooling and heating into a room by a duct, and has a box-like casing (1) and a blower duct (5). ) And a suction duct (4). As described above, the air conditioning system is a system that supplies air for cooling and heating from a main unit provided with a heat exchange device or a control system to a living room or the like. Is installed in each room to adjust individually. Alternatively, in a small-scale air conditioning system, at least one blower is installed.

The casing (1) is usually formed in a substantially rectangular parallelepiped or cubic box shape, and accommodates a blower fan (2) and a coil unit (3) for heat exchange. For example, a sirocco fan is used as the blower fan (2). The coil unit (3) is a unit that constitutes a part of the above-described heat exchange device, and is configured so that a heat medium whose temperature has been adjusted is supplied from the main equipment. In the casing (1), a coil unit (3) is arranged in front of the blower fan (2), whereby the air sucked by the blower fan (2) is blown out through the coil unit (3). You.

An air duct (5) for sending out the heat exchanged by the coil unit (3) is connected to the front end of the casing (1). The tip of the air duct (5) extends to the outlet of the living room. In the blower of the present invention, a suction duct (4) for taking air into the casing (1) is connected to a side surface of the casing (1) so that the air duct can be disposed close to the building. One end of the suction duct (4) usually extends to the suction port of the living room. In the present invention, the side surface of the casing (1) refers to a surface other than the front end surface and the rear end surface.

As described above, the blower of the present invention has a structure in which the suction duct (4) is connected to the side surface of the casing (1) without bending the suction duct (4). ) Can be taken directly into the casing (1) from a direction perpendicular to the sending direction. Therefore, when the casing (1) is installed behind a ceiling, the rear end of the casing (1) can be placed close to the wall (6), for example. That is, when the blower of the present invention is installed, FIG.
As shown in (1), the installation distance (L) from the wall (6) to the front end of the casing (1) can be set to a length substantially corresponding to the entire length of the casing (1), and the installation can be further reduced in space.

Although not shown, in the blower of the present invention, the second suction duct may be connected to the rear end of the casing (1). In the blower of the present invention to which the second suction duct is connected in addition to the above-mentioned suction duct (4), the load on the blower fan (2) is increased even when the intermediate path of the duct is long or bent. The air can be sufficiently taken in without causing the air to flow.

[0014]

According to the blower of the air conditioning system according to the present invention, the air can be taken directly into the casing from a direction perpendicular to the direction in which the blower duct is sent out without bending the suction duct. When installed on the back or the like, the rear end of the casing can be installed close to a structure such as a wall or a beam, and the installation can be further reduced in space.
