How to Deal with the Noise of Modular Air Source Heat Pump?

Noise treatment of modular air source heat pump is a complex and multifaceted project, which requires comprehensive consideration of the source of noise, the transmission path and specific noise reduction measures. The following are detailed noise treatment methods:

1. Vibration isolation measures

Vibration isolators should be used between air source heat pumps and water pumps and foundations to reduce vibration transmission. The floating ground approach can effectively reduce vibration and is suitable for pump groups with strong vibration.

When installing the heat pump, rubber vibration damping pads can be used, and ensure that the level of the heat pump meets the requirements of the technical specifications.

2. Noise reduction measures

Installing a silencer on the upper part of the heat pump chassis can effectively reduce noise.

For air sound treatment, a cast-in-place concrete sound insulation wall with a thickness of 120 mm can be used to reduce the transmission of air sound.

For the noise generated by components such as fans and condensers, it can be reduced by setting up silencer equipment.

3. Sound absorption treatment

Sound absorption treatment can be carried out between water pumps, such as pasting sound-absorbing materials inside the rain cover, which can effectively reduce the noise generated by the operation of the water pump.

Cover the inside of the water heater shell with a layer of sound-absorbing cotton to reduce the noise when the compressor is running.

4. Pipeline sound insulation

For the sound insulation treatment of the pipeline, the pipeline can be sealed and sound-insulated at the wall, and the pipeline can be sound-insulated.

Use stainless steel bellows or rubber flexible joints to reduce the noise caused by pipeline vibration.

5. Working time period control

Set the working time period of the air source heat pump to avoid running at night or during rest time, so as to reduce the impact on residents.

6. Equipment selection and installation

Give priority to low-noise brand equipment, and ensure that the bracket is stable during installation to avoid metal impact sound.

Ensure that the equipment is kept at a certain distance from the surrounding buildings to ensure effective heat diffusion and natural noise attenuation.

7. Other measures

For large-scale air source heat pump application projects, special noise control design should be carried out to predict the equipment emission noise and its impact on noise-sensitive buildings, and formulate reasonable noise control measures.

Use closed or semi-closed soundproof enclosures to reduce noise. The soundproof enclosures should be equipped with ventilation structures so as not to affect the normal operation of the equipment.

Through the above comprehensive measures, the noise of modular air source heat pumps can be effectively reduced to ensure that they will not have a significant impact on the surrounding environment during operation.
