Method of controlling noise of refrigerator

1. Start with the compressor

Starting from the compressor is the wisest choice. Since the compressor is the most noisy component of the refrigerator, it should be focused on. To solve and control the noise problem of the refrigerator, you should also start with the compressor of the refrigerator. .

(1) Determine whether the compressor is faulty

The compressor is not malfunctioning and the noise is normal. If the noise is harsh or the noise suddenly becomes louder, there may be a problem. After the compressor failure is resolved, the compressor noise will disappear.

(2) Overload operation is prohibited.

Overload operation will increase the noise of the refrigerator compressor, so overload operation should be avoided.

2. Water pump

The water pump is an indispensable part of the refrigerator. The chilled water requires a water pump and cooling water (if it is a water chiller). The normal operation of the water pump may also produce noise. The method to reduce the noise of the water pump is to maintain, clean, and lubricate regularly, or to use a good quality water pump.

3. Fan

Whether it is an air-cooled machine or a water-cooled machine, a fan system is used. That is to say, the fan is not only used for heat dissipation and temperature reduction of the air-cooled refrigerator, but also used for the water-cooled chiller. Regular lubrication and cleaning of dust covers should be used to reduce fan noise.

4. Connection and fixation between the box plate and components

Whether it is a box-type machine or an open-type refrigerator, if the connection and fixing between the box plates or parts are not good, noise will also be generated. Please check it and find the problem, please deal with it in time.

5. Machine feet

You should pay attention to whether the floor of the box-type machine or the open-type refrigerator is flat and whether the machine feet are fixed. If you find the noise caused by the machine feet and the uneven ground, it is recommended to fix and level the ground again!
