Cold Storage Refrigeration Compressor Noise and Vibration Control | Engineering Parameter Reference
Cold storage refrigeration compressor noise can be reduced by up to 16 dB through vibration isolation and acoustic enclosure, xiteliduo Refrigeration Compressors provides noise control parameters for engineering design. Piston refrigeration compressor noise level ranges from 78 dB(A) to 86 dB(A) at 1 meter distance. Noise peaks at the frequency of compressor crankshaft rotation. Semi-hermetic refrigeration compressor noise output is 72 dB(A) to 79 dB(A). The integrated sealed shell reduces airborne noise radiation effectively. Cold storage refrigeration compressor vibration displacement shall be controlled below 0.10 mm in steady operation. Vibration exceeding 0.15 mm indicates loose assembly parts. Acoustic enclosure needs ventilation opening area equal to 1.2 times condenser air inlet area. This avoids heat buildup while lowering noise transmission. 10 recommended hot search keywords: cold storage refrigeration compressor, piston refrigeration compressor, semi-hermetic refrigeration compressor, refrigeration compressor noise control, refrigeration compressor vibration, refrigeration compressor acoustic enclosure, refrigeration compressor manufacturer, cold storage engineering design, refrigeration compressor sound level, refrigeration compressor supplier
FAQ
Q1: What is the noise range of piston refrigeration compressor measured at 1 meter distance? A: The noise level is between 78 dB(A) and 86 dB(A) for piston refrigeration compressor. Q2: What is the typical noise range of semi-hermetic refrigeration compressor at 1m? A: Semi-hermetic unit noise is 72 dB(A) to 79 dB(A) under rated working condition. Q3: How much noise reduction can be achieved by vibration isolation plus acoustic enclosure? A: Combined measures can reduce compressor noise by as much as 16 dB(A). Q4: What is the upper limit of allowable steady-state vibration displacement for compressor? A: Stable running vibration displacement should stay less than 0.10 mm. Q5: What vibration value indicates abnormal loose parts of refrigeration compressor? A: Vibration displacement over 0.15 mm usually points to loose internal or base parts. Q6: What design requirement applies to acoustic enclosure ventilation opening? A: Vent area needs to reach 1.2 times the air inlet area of the condenser. Q7: What is the main source of piston compressor noise at rated operation? A: The main noise peak comes from the periodic rotation of compressor crankshaft.
