Although the refrigerator did not have any problems under working conditions, the noise was relatively large as the "age" increased. However, it is a pity to eliminate it because of the noise. The following methods can effectively reduce the noise.
★The back and the wall are at a certain angle of inclination
The back side of the refrigerator is inclined at a certain angle to the wall surface, and the back side is inclined at an angle of l-3 degrees to the wall surface, and the refrigerator has one side opening and one side opening small, and has a trumpet shape. The large side emits a lot of noise and should face the object; the small side has less noise and should face the active area of ​​the person.
★The pipeline and the box are firmly fixed
Check to see if the connection reinforcement between the outer pipe and the casing is loose, so as to avoid resonance when the compressor is working. In order to avoid loosening, the outer pipe must be fixed, and the bolt should be spring washer.
★The compressor base should be firm
If the compressor is pressed tightly by hand, the noise is obviously reduced, and the noise is increased by the hand. This situation is generally caused by uneven force of the fixed vibration damping pad of the compressor base or loose bolts and unstable compressor bottom plate. The connecting part bolts should be adjusted, tightened and replaced with a spring-loaded washer.
★ Use rubber block to suppress tube vibration
If the refrigerator is in use, the noise is large. The bicycle tire can be taken out, cut into a round shape with a diameter of 30 mm, and a circular hole with a diameter of about 5 mm is cut out in the middle, and then cut from the outside to the center to stick the rubber to the tube. on. When the refrigerator compressor is running, touch the pipe by hand. If there is a tube with a feeling of shaking, you can put on several rubber blocks. A refrigerator needs 10-20 sets, and the noise will drop down immediately. This is because the rubber block suppresses the "resonance" produced by the vibration of the tube.
★ Appropriately heighten the four corners of the refrigerator
Raise the refrigerator by 3-6 cm and adjust the balance of the four corners to increase the air convection space at the bottom of the cabinet. In this way, compressor noise and other noise from the bottom of the cabinet are removed from the bottom of the cabinet, reducing noise from both sides and the upper part of the refrigerator.
