Abstract

The present invention proposes a sound insulation cover, an air conditioner outdoor unit and a noise reduction method. The sound insulation cover can be set on noise equipment with noise points, and includes a shell and a sound insulation board inside the shell. The shell and The sound insulation board surrounds and forms a sound insulation chamber that can collect noise sound waves in the noise equipment, the sound insulation chamber includes a collection port corresponding to the noise point, and a noise reduction unit is arranged in the sound insulation chamber. The sound insulation cover effectively improves the noise reduction effect by collecting the noise sound waves at the noise point into the sound insulation cavity for targeted treatment. The outdoor unit of the air conditioner includes the above-mentioned soundproof cover, which can effectively reduce the noise of the outdoor unit of the air conditioner. The noise reduction method greatly improves the effect of noise reduction by setting a sound insulation cavity for collecting noise sound waves, and performing active noise reduction in the sound insulation cavity.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a sound insulation cover, an outdoor unit of an air conditioner and a noise reduction method. Background technique [0002] In recent years, equipment noise reduction has become an important issue for mechanical equipment, especially outdoor unit noise has become a key complaint issue for air-conditioning manufacturers, and compressor noise is the main source of outdoor unit noise, and it is also the main complaint point . Therefore, all air-conditioning manufacturers are now investing a lot of manpower and material resources to solve the compressor noise problem and improve the competitiveness of their products. However, the existing compressor noise reduction measures are all passive sound-absorbing and noise-reducing designs, mainly through the design of porous sound-absorbing materials and sound-insulating materials. OA value, the noise reduction effect is not sati...
