Uncover Why Solar DC Freezer Produces Noise September 09, 2020 9:14 PM

As we all know, the Solar DC Freezer always makes sound during work, and many manufacturers try their best to reduce the sound to a level that does not affect us. If the solar DC freezer makes a loud noise during work, it is called noise. But this kind of noise seriously affects our life. What's going on?

In fact, there is a lot of noise in the operation of the solar DC freezer, so it can be judged that something is wrong with it. Because only in this way will its sound exceed our normal tolerance and become noise. Therefore, once we encounter such a situation, we should repair it in time, so as not to stop causing greater damage to the solar DC freezer in time, and let us not be disturbed by noise.

The noise source of the solar DC freezer is mainly the internal compressor. Once the clearance between the piston and the cylinder head is too small, it will directly impact and make a lot of noise. Moreover, if metal fragments fall into the cylinder (compressed air) or moisture is accumulated, it will also cause impact and noise inside the cylinder. If the refrigerator and freezer are used for a long time, the internal parts are worn (a basic type of failure of parts), which leads to excessive internal clearance, resulting in a very loud knocking sound.

The resonance of the refrigerated display cabinet will also cause noise, so we should also inspect whether the link between the pipeline and the cabinet is loose, whether the compressor is fixed, whether the floor of the compressor is fixed or loose, and whether it will cause resonance of the compressor. The solar DC freezers should be placed flat, which can also cause noise, so we can add rubber pads under them to reduce noise.
