 TECHNICAL FIELD The present invention relates to an air conditioning panel in which a heat source device for generating cold air is attached to a partition to enable a refrigerant-air type personal air conditioning.

[0002]

[Prior art]

 In recent years, personal air-conditioning is adopted in places where OA equipment is used, and thus air-conditioning panels combining a panel that also serves as a partition and heat source equipment have come to be used. As shown in FIG. 6, this type of air conditioning panel has a panel 31 having a heat source device cover 33 having a heat source device 32 incorporated therein, an inlet port 34 provided in the heat source device cover 33, and a compressor and a blower inside. , A condenser, an evaporator (all not shown) and the like are provided with a heat source device 32 having a refrigeration circuit, and the heat source device 32 is provided with an exhaust heat exhaust port and a cool air outlet (all not shown). The provided connecting ducts 35 and 36 are connected to each other. The panel 31 incorporates an exhaust air passage 37 and a cool air passage 39 which communicate with the connecting ducts 35 and 36, and has an exhaust port 38 at the top and a cold air outlet 40 at the upper side.

With the above structure, the indoor air is taken in through the intake port 34 of the heat source device cover 33, a part of which is passed through the condenser of the heat source device 32 to absorb heat, and the connection duct 35 which connects the heat source device 32 and the panel 31. Exhausted from the exhaust port 38 through the exhaust ventilation path 37 in the panel 31. Further, the other sucked air is passed through the evaporator of the heat source device 32 to be cold air, and is blown out from the cold air blowout port 40 through the cold air flow passage 39 in the panel 31 through the connecting duct 36.

[0004]

[Problems to be solved by the device]

 In such a conventional air-conditioning panel, vibrations from the compressor or the blower of the heat source device 32 are transmitted to the panel 31 connected by the connecting ducts 35 and 36, and the panel 31 vibrates or, in a significant case, a vibration sound. There was a problem that it occurred.

The present invention solves the above problems, and an object of the present invention is to provide a quiet air conditioning panel that does not amplify or resonate the vibration of the heat source device.

[0006]

[Means for Solving the Problems]

 A first means for achieving the object of the present invention is a heat source device including a compressor, a condenser, an evaporator, and a refrigeration circuit having a blower, and having a heat exhaust port and a cool air outlet, and The exhaust heat inlet and the cold air inlet corresponding to the cold air outlet, and the cool air inlet, and a panel having a ventilation passage communicating one end with these inlets and the other end with the outlet, A connection duct that connects the heat port and the exhaust heat intake port, and the cold air outlet port and the cold air intake port, respectively, is provided, and the connection duct is formed of a vibration absorbing elastic body.

A second means for achieving the object of the present invention is that the connecting duct is formed of a rigid body, and the exhaust heat intake port and the cool air intake port of the panel and the exhaust heat intake port and the cold air exhaust port of the heat source device are connected to each other. The connecting part is connected to the connecting part via a vibration absorbing elastic body.

[0008]

[Action]

 According to the first aspect of the present invention, since the connecting duct that connects the heat source device and the panel is formed of the vibration absorbing elastic body, the vibration generated from the compressor or blower of the heat source device is connected by the connecting duct. Since the vibrations are absorbed and damped, it is possible to reduce the resonance of the panel vibration and the occurrence of resonance.

According to the structure of the second means, the connecting duct is made of a rigid body, and the vibration absorbing elastic body is interposed in the connecting portion between the heat source device and the panel. Therefore, the vibration generated by the heat source device is vibration absorbing elastic. Since it is absorbed by the body, the transmission of vibration to the panel is blocked.

Embodiment A first embodiment of the present invention will be described below with reference to FIGS.

As shown in the drawing, in the air conditioning panel of the present invention, a heat source device cover 3 accommodating a heat source device 2 is attached to a panel 1 having a hollow inside. The heat source device 2 has a compressor, a blower (neither of which is shown), a condenser coil 2a and an evaporator coil 2b, and the air sucked by the blower from a suction port 2c provided in the heat source device cover 3. Part of the heat is absorbed by the condenser coil 2a and discharged as exhaust heat from the exhaust port 2d provided above the heat source device 2, and other intake air is cooled by the evaporator coil 2b to the intake port 2c. It can be discharged from the air outlet 2e provided adjacently.

The panel 1 is provided with an outlet 4 for cool air at the upper front surface thereof and an exhaust port 7 at the top surface. Further, as shown in FIG. 1, a partition plate 1b having a good heat insulating property is formed inside to divide the two ventilation passages 5a and 5b. The outlet 4 of the panel 1 is connected to the outlet 2e of the cold air of the heat source device 2 from the air passage 5b by a connecting duct 6a formed of a vibration absorbing elastic body, and the outlet 4e of the panel is connected to the outlet 4e of the cool air. Is being blown out. Further, the ventilation duct 5a is connected to the exhaust port 2d by a connecting duct 6b formed of a vibration absorbing elastic body, and is discharged from the exhaust port 7 of the exhaust heat panel 1 of the heat source device 2.

In the above configuration, the vibration generated from the compressor and the blower in the heat source device 2 is transmitted from the air outlet 2e and the exhaust port 2d to the connecting ducts 6a and 6b, but the connecting ducts 6a and 6b absorb the vibration absorbing elasticity. Since it is formed by the body, the vibration is attenuated and the vibration transmission to the panel 1 can be reduced.

Next, a second embodiment of the invention will be described with reference to FIGS. 3 to 5. The same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

As shown in the figure, the connecting duct 21 is composed of a duct portion 21a formed of a rigid body and a connecting portion 21b formed of a vibration absorbing elastic body, and is connected to the ventilation passages 23a and 23b of the panel 22. The connecting portion 21b formed of the vibration absorbing elastic body and the screw 21d are fixedly communicated with each other via the packing 21c of the vibration absorbing elastic body. Further, the air outlet 24a and the air outlet 24b of the heat source device 24 are also configured to communicate with the duct portion 21a via a connecting portion 21b formed of a vibration absorbing elastic body.

In the above structure, the vibration generated in the heat source device 24 is attenuated in the connecting portion 21, is transmitted to the duct portion 21a, and is further attenuated by the connecting portion 21b connected to the ventilation passages 23a and 23b of the panel 22. The vibration transmission to the panel 22 can be reduced.

[0017]

[Effect of device]

 As is apparent from the above-described embodiments, according to the present invention, since the connecting duct itself that connects the panel and the heat source device is formed of the vibration absorbing elastic body, the installation is simple and the transmission of vibration is effectively reduced. It is possible to provide an air-conditioning panel with little vibration generated in the panel and no vibration noise. In addition, the rigid connecting duct is attached via a vibration-absorbing elastic body to provide an air-conditioning panel that is low in cost and effectively does not generate vibration noise.
