The air conditioning unit generates significant noise pollution during operation, affecting the living and working environment of residents. Its noise sources consist of the following components:
1. Fan intake and exhaust noise
2. Fan reducer and motor noise
3. Compressor noise
4. Air conditioning unit pump, piping, and valve noise.
When the air conditioning unit is operating normally, the noise level at the exhaust outlet exceeds 80 dB(A); the noise level about 1 meter away from the equipment is around 75 dB; after the equipment is turned on, the noise level at the factory boundary may exceed the standard.
After analysis, the noise generated by the air conditioning unit during operation mainly includes: aerodynamic noise from the exhaust outlets, compressor noise, mechanical noise from the unit's operation, pipeline resonance noise caused by the equipment, motor noise, and so on.
Key considerations for solving air conditioner noise pollution include the relative position between the source equipment and sensitive residential locations. Measures such as vibration reduction, sound insulation, and noise suppression can be adopted.
