Example Embodiment

[0034] The following combination Figure 1~2 An embodiment of the present invention will be described in detail.

[0035] The noise reduction device of compressor includes sound insulation cover 1, which is arranged in engine room 4 to wrap the compressor, and is characterized by further including sound attenuation box 2 arranged in engine room 4 to absorb noise and reduce vibration of the wall plate of engine room 4, and sound absorption structure 3 arranged in engine room 4 to absorb reflected sound waves, and sound absorption structure 3 is arranged between sound attenuation box 2 and sound insulation cover 1.

[0036] The noise reduction device of the compressor includes a sound insulation cover 1, a sound attenuation box 2 and a sound absorption structure 3. The sound insulation cover 1 wraps the compressor to prevent the compressor noise from spreading to the cabin cavity, the sound attenuation box 2 absorbs the noise in the cabin 4 space and reduces the vibration of the cabin w

Abstract

The invention provides a noise reduction device for a compressor. The noise reduction device comprises a sound insulation cover which is arranged in a cabin and wraps the compressor, and is characterized by further comprising a silencing box which is arranged in the cabin and used for absorbing noise and reducing vibration of a cabin wall plate and a sound absorption structure which is arranged inthe cabin and used for absorbing reflected sound waves, wherein the sound absorption structure is arranged between the silencing box and the sound insulation cover. The sound insulation cover is usedfor wrapping the compressor to prevent the noise of the compressor from spreading to the inner cavity of the cabin, the silencing box is used for absorbing the noise in the cabin space and reducing vibration of the cabin wall, and the sound absorption structure is used for absorbing the sound waves which are continuously reflected back and forth between the sound insulation cover and the silencing box, so that the noise in the cabin space is reduced, the outward propagation of the noise from the cabin is effectively reduced, and the reliability and effectiveness of noise reduction of the compressor are effectively improved. The invention further provides a noise reduction method for the compressor.
