Air-cooled (heat pump)Unit

 

Air-cooled (heat pump) Unit is the refrigeration and heating equipment of buildings all over the year. Cold storage, refrigeration equipment usually use the modular compressors as the refrigerator, air-cooled as the cooling method . 


     Air-cooled (heat pump) units is usually installed in the outdoor roof, the noise would affect the surrounding environment and the vibration would also have great impact on the lower deck of the rooms, especially for high-end hotels, homes, office buildings.


The vibration and noise sources :

 

1) the construction vibration caused by the unit and pipeline the vibration , the solid sound transmission ;

 

2) Noise produced by the compressor and fan of the unit radiate through air to the surrounding environment.

 

The usual noise control measures:

 

 1) install soundproof room and install the entrance and exhaust muffler. 


 2) install noise barriers , the unit basis and the pipeline should be damping processed .


     According to different situations, the air-cooled (heat pump)units of the Noise Control Unit should be controled synthetically to achieve the objectives of the governance requirements.
