Description

[Technical field]

[0002] The utility model relates to the technical field of compressors, in particular to a sound insulation device for compressors. [Background technology]

[0004] As an important part of the air conditioning refrigeration system, the air conditioning compressor compresses and drives the refrigerant through mechanical movement to achieve the cooling or heating function of the air conditioner. This mechanical movement causes the compressor itself to vibrate, and this vibration is often accompanied by the generation of noise.

[0005] First, the compressor will cause structure-borne noise through vibration, that is, the vibration noise of the surrounding structural components caused by vibration. This noise usually manifests as a low-frequency hum or rumble, which will continue to exist as the compressor runs. Secondly, under certain specific conditions, the vibration of the compressor may also cause resonance. Resonance occurs when the vibration frequency of the compressor matches the natural frequency of the surrounding structure. Resonance causes a significant increase in vibration, resulting in greater noise. This noise usually manifests as a sharp whistle or buzzing sound.

[0006] Whether it is structure-borne noise or resonant noise, it will have a negative impact on people's quality of life. For example, air conditioning running at night may disturb people's sleep, causing insomnia or reduced sleep quality. In addition, long-term exposure to high noise environments may also cause damage to people's hearing and health. [Contents of the utility model]
