The noise level of low temperature chiller and the sound insulation design suggestions for the installation location can be analyzed and suggested from the following aspects:

1. Noise level and equipment selection

The noise of low temperature chiller mainly comes from components such as the compressor, fan and water pump. According to the information I found, choosing a low-noise model of chiller is the key to reducing noise. For instance, the noise level of some equipment is around 56dB(A), while the sound pressure level of a generally good chiller at a distance of 1 meter should be controlled below 70 to 80 decibels. Therefore, when making a purchase, low-noise models should be given priority.

2. Installation location and sound insulation design

(1) Installation location selection

- Stay away from sensitive areas: The chiller should be installed in a location far from areas where people are active or sensitive areas to minimize the impact on the surrounding environment. For instance, large water chillers are recommended to be installed in dedicated machine rooms or away from densely populated areas.

- Reasonable layout: During the design stage, noise control factors should be fully considered, and noise transmission and interference should be reduced through reasonable layout. For instance, the noise sources should be centrally arranged in a corner of the machine room or a separate room, and measures such as soundproof doors and Windows should be adopted for enclosure treatment.

(2) Sound insulation design measures

- Sound insulation barriers and walls: Installing noise barriers around or inside the chiller room can significantly reduce the impact of noise on the surrounding environment. Barrier materials can be selected from metal plates, concrete walls or specially designed sound insulation boards. At the same time, sound insulation of walls and renovation of door and window systems are also effective sound insulation measures.

Vibration reduction and sound insulation measures: Install shock-absorbing pads or spring vibration isolators at the bottom of the equipment to reduce vibration transmission and equipment noise. In addition, flexible joints are used at the pipe connections to reduce aerodynamic noise.

Sound-absorbing materials: Sound-absorbing materials such as sound-absorbing boards and sound-absorbing cotton are used inside and around the computer room to absorb and reduce the reflection and transmission of noise.

3. Maintenance and Management

Regular maintenance: Regular cleaning and maintenance of the equipment to keep it in good operating condition can help reduce noise. For instance, regularly clean the condenser and evaporator, inspect the circulating water pump and pipelines, and replace the cooling water, etc.

- Regular monitoring: After installation, regularly monitor the noise level and adjust the noise reduction measures as needed to cope with changes in operating conditions or wear and tear.

4. Comprehensive solution

By comprehensively applying measures such as equipment selection, installation location, sound insulation design and maintenance management, the noise level of low temperature chiller can be effectively reduced, creating a more peaceful working environment.

Summary

The noise level of low temperature chiller and the sound insulation design of the installation location need to be comprehensively considered from multiple aspects such as equipment selection, installation location, sound insulation measures, and maintenance management. Through scientific planning and effective implementation, noise levels can be significantly reduced, and the comfort and safety of the working environment can be enhanced.
