Standard semi-hermetic cold storage piston compressor produces 78dB sound pressure at one-meter measuring distance. Urban commercial cold storage inside supermarkets requires noise below 70dB at the property boundary, so noise reduction modification is mandatory for these projects. Multi-layer rubber shock pads are installed between piston compressor base and concrete foundation. The shock absorber can reduce vibration transmission rate to below 18%. Without shock absorption measures, pipeline vibration may cause refrigerant leakage after 18 months of continuous operation. Acoustic enclosure is the main solution to cut noise of piston refrigeration compressor. The sound insulation shell can reduce noise by 8 to 12 dB, while maintaining enough ventilation space for condenser heat dissipation. Poor ventilation inside enclosure will cause high exhaust pressure and power consumption rise by 10%. Piping soft connection is required on suction and discharge pipelines of piston compression unit. Metal bellows absorb vibration generated by reciprocating piston movement and stop vibration transferring to rigid building pipe network. Pipe brackets should also add rubber damping sleeves. The noise of piston refrigeration compressor comes from two sources: mechanical reciprocating impact and gas flow noise. Optimized muffler design reduces gas pulsation noise by 6dB, while precision-machined crankshaft and piston assembly lower mechanical knocking noise. xtldcool supplies silent customized piston compressor versions for supermarket cold storage. Vibration inspection should be performed monthly after cold storage commissioning. If vibration amplitude exceeds 0.12mm, operators need to check shock absorber aging and foundation bolt looseness. Aging rubber pads lose damping performance after 4 to 5 years. For cold storage built adjacent to residential areas, compressors are usually placed in isolated equipment room. Wall sound insulation material and air inlet silencer are combined to prevent noise spreading outward. This integrated scheme can satisfy strict urban environmental assessment standards. FAQ Q: What is the standard noise value of semi-hermetic piston compressor at 1m? A: Standard unit generates about 78dB sound pressure at one-meter measuring point. Q: What noise limit is usually required for urban supermarket cold storage? A: Noise at property boundary should be controlled below 70dB. Q: What vibration transmission rate can multi-layer shock pads achieve? A: Shock absorber can reduce vibration transmission rate to less than 18%. Q: How much noise reduction can acoustic enclosure achieve for piston compressor? A: Proper sound enclosure can cut noise level by 8~12dB. Q: What risk exists if acoustic enclosure lacks ventilation design? A: Poor ventilation raises exhaust pressure and power consumption by 10%. Q: How often to inspect piston compressor vibration after commissioning? A: Monthly vibration inspection is recommended for urban commercial cold storage. Q: Does xtldcool offer silent customized piston refrigeration compressor? A: Yes, customized low-noise piston compressors for supermarket cold storage.
