Characteristics of Air-Cooled Chiller

In the design and configuration of industrial water chiller, the noise of compressor varies with different models and installation methods. The noise of fully enclosed compressor is lower than that of semi enclosed compressor. The noise of screw compressor is lower than that of piston compressor. The noise of several small refrigeration compressors is lower than that of a single compressor in the same refrigeration.

Therefore, in the chiller, the noise of axial flow fan of air-cooled chiller is different due to different wings and different speeds. The noise of eight pole motor is lower than that of six pole motor. Therefore, the design of the chiller should be flexibly selected according to the surrounding conditions and noise requirements, and strive to be economical and reasonable. In order to reduce noise and vibration, the air-cooled unit and water pump shall be provided with damping foundation, the inlet and outlet of the chiller and water pump shall be provided with soft joints, and the silencing wall shall be set around the air-cooled chiller.

When the air-cooled chiller is running, the vibration and noise generated by the operation of the refrigeration system and various equipment will have a great impact on the surrounding environment. There is a strong vibration on the ground. The fan control range of the air-cooled chiller should be between 60 dB and 70 dB. In serious cases, people will not be able to work and rest normally. The best anti noise control method of air-cooled chiller is to isolate the industrial chiller, cooling water pump and system pipeline. The chiller shall be placed in the machine room or the production workshop of the factory for sound absorption and sound insulation. It shall be placed in a place with unobstructed exhaust to avoid discharge and backflow.
