What are the Common Locations of Air-cooled Chiller Noise?

Mar. 30, 2020

As we all know, when using Air Cooled Chiller, it is necessary to pay attention to noise control issues, to be able to comprehensively deal with noise within an effective time, and to prevent various noise problems from affecting the normal operation of the equipment. Although the air-cooled chiller will cause slight noise problems in the daily use process, it is within the acceptable range. If the noise range of the air-cooled chiller continues to expand, it means that the air-cooled chiller has a fault and needs to be comprehensively tested.

Compressors, circulating water pumps and cooling fans are the main noise sources of air-cooled chiller. Since the operation of this type of equipment generates noise, the change in the size of the noise mainly depends on the above types of equipment. In the case of increasing noise, companies need to conduct comprehensive inspections of various internal accessories to ensure the root cause of the increased noise, so that they can be processed quickly and efficiently. So how to deal with the noise of air-cooled chiller? The following Water Cooled Chiller Manufacturer will come to tell you.


The method of dealing with noise is very simple. If the air-cooled chiller is a mechanical operating noise, the range and size of the noise can be reduced by means of lubrication. If it is caused by the failure of the internal parts, you can repair the parts in time or replace the new internal parts to obtain the maintenance effect of reducing noise.


As for the water-cooled chiller, if the noise is caused by the water pump, it means that there may be problems with the water quality, and the enterprise needs to configure the water quality treatment system according to the use requirements of the air-cooled chiller. Only by ensuring that the water quality meets the minimum standards for air-cooled chiller, can the safe operation of the pump be guaranteed, thereby preventing the pump from overloading and causing serious noise.


Since the structure of the air-cooled chiller is relatively simple, it is easy to distinguish the location where noise is generated. In the case of increasing noise from air-cooled chiller, as long as the source of the noise is determined according to the specific noise type, it can be processed quickly and effectively, thereby improving the efficiency of use of air-cooled chiller and avoiding noise. Affects, resulting in various failures of the air-cooled chiller.


Although the air-cooled chiller is provided with multiple protection devices, these are to prevent the failure from directly damaging the unit. If the enterprise wants to ensure that the air-cooled chiller has high refrigeration efficiency and long service life, it must remember to do regular maintenance. Finally, Air Cooled Screw Chiller Supplier will share with you a few tips for maintaining and maintaining air-cooled chiller.


1. Check the stability of the voltage and current of the air-cooled chiller; when the air-cooled chiller is working normally, the standard voltage is 380V (there are differences between different manufacturers, mainly based on the manufacturer's instructions), and the current is 11A -15A range is normal;


2. Check whether the refrigerant of the chiller is reduced; this can be judged by the high and low pressure gauge values on the front of the air-cooled chiller. When the chiller operates normally, the high pressure is in the range of 11-17kg and the low pressure is in the normal range of 3-5kg. When the machine is stopped, the high pressure and low pressure are all about 0.6kg;


3. Regularly clean the system; when the air-cooled chiller is running for 6 months, the entire system must be cleaned, such as pipes, filters, condensers, fans, etc., especially the fans. Like our commonly used fans, they are covered with dust and affect heat dissipation. Therefore, the cooling efficiency will be directly reduced.
