[Structure] A first dust-absorbing and sound-absorbing plate 4 (a plate having a noise-reducing and dust-collecting effect by utilizing turbulent agglomeration due to collision of winds) at a position facing an inlet 3 of a part 2 of return air 1 coming out of a room. )
And the inlet of the total heat exchanger 5 is provided in the middle of the passage,
The inlet 15 of the fresh outside air 7 communicates with the total heat exchanger 5, the outlet 16 thereof communicates with the through hole 8, and the second dust absorbing and sound absorbing plate 10 is provided below the through hole 8. The sound absorbing plate 10 faces the inlet 17 of the other portion 9 of the return air 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat recovery dust unit in an air conditioner used in an office, a store, a game hall, or the like.

[0002]

[Prior art]

 Conventionally, in the above-mentioned air conditioners, ducts were installed on site to connect each device, and part of the return air from the room was heat-exchanged with fresh air and exhausted to obtain fresh air. Removes dust with the rest of the return air and returns it to the room through the air conditioner.

[0003]

[Problems to be solved by the device]

 However, this imposes a heavy burden on the dust collector and makes a lot of noise, and the filter of the air dust collector had to be frequently replaced.

[0004]

[Means for Solving the Problems]

 The present invention has been made in order to solve the above-mentioned problems, and uses a special dust absorbing and sound absorbing plate in the air passage for low noise and dust collecting effect. A first dust-absorbing and sound-absorbing plate 4 (a plate that reduces noise and collects dust by utilizing turbulent flow agglomeration due to wind collision) is provided at a position facing the inlet 3 of the portion 2 of the air 1, and the passageway The inlet of the total heat exchanger 5 is provided in the middle, the inlet 15 of the fresh outside air 7 communicates with the total heat exchanger 5, its outlet 16 communicates with the passage 8, and below the passage 8 the second Dust absorption / sound absorption plate 10 is provided, and this second dust absorption / sound absorption plate 10 is a heat recovery dust collection unit which is opposed to the inlet 17 of the other part 9 of the return air 1.

[0005]

[Action]

 A part 2 of the return air 1 coming out of the room is introduced from the inlet 3 and becomes the first dust absorbing and sound absorbing plate 4 (a plate that has a noise reducing and dust collecting effect by utilizing turbulent aggregation due to collision of wind). It hits or is discharged from the exhaust port 6 through the total heat exchanger 5. The fresh outside air 7 exchanges heat with the part 2 of the return air 1 in the total heat exchanger 5 and hits the second dust absorbing and sound absorbing plate 10 together with the other part 9 of the return air 1 through the passage 8 to generate electricity. It is supplied into the room through the dust collector 11 and the air conditioner 12. Alternatively, it directly communicates with the passage 13 of the other part 9 of the return air 1.

【Example】

 FIG. 1 is a perspective view of a first embodiment of the present invention, in which a first dust-absorption and sound-absorption plate 4 (disturbed by a wind collision) is positioned at a position facing an inlet 3 of a part 2 of return air 1 coming out of a room. A plate having a noise reduction effect and a dust collection effect is provided by using flow coagulation, an inlet of the total heat exchanger 5 is provided in the middle of the passage, and an inlet 15 of fresh outside air 7 communicates with the total heat exchanger 5. The outlet 16 communicates with the downward-facing passage 8 and a second dust-absorption / sound-absorbing plate 10 is provided below the passage 8 and the second dust-absorption / absorption plate 10 is provided for the other portion 9 of the return air 1. Face the entrance 17 of the. The above parts are integrated, and the integrated unit is fitted to the air conditioner.

FIG. 2 is a cross-sectional view of the first dust absorbing and sound absorbing plate 4 and the second dust absorbing and sound absorbing plate 10, in which the sound absorbing and absorbing material 21 is adhered to the outer plate 20 and the air layer 22 is interposed therebetween. And a filter 23 is provided.

The operation of this device will be described. As shown in FIG. 3, a part 2 (25%) of the return air 1 coming out of the room is introduced from the inlet 3, and the first dust absorbing and sound absorbing plate 4 (the noise reduction due to the turbulent aggregation due to the collision of the wind) is generated. When it hits a plate having a dust collecting effect), it is discharged through the exhaust port 6 through the total heat exchanger 5. The fresh outside air 7 exchanges heat with the part 2 of the return air 1 in the total heat exchanger 5, and passes through the passage 8 along with the other part 9 (75%) of the return air 1 to the second dust absorbing and sound absorbing plate. 10 is supplied to the room through the electric dust collector 11 and the air conditioner 12.

[0009]

[Effect of device]

 As described above, in the present invention, since the special dust absorbing and sound absorbing plate is used in the air passage, the noise reduction and the dust collecting effect can be achieved, and the replacement of the filter can be saved.
