How low can the noise of the refrigerator be controlled now?

At present, the noise level of common refrigerators in the market is basically controlled at about 38 decibels, and the good ones are generally at 35 decibels, while refrigerators below 35 decibels are not available in the market. However, TCL recently produced a silent refrigerator with only 33 decibels, which caused a sensation in the industry.

this refrigerator is TCL 46P6-U, which has such an extreme mute effect, because their R&D team has further optimized and adjusted the noise source of the refrigerator. On the fan, this refrigerator uses a vortex centrifugal variable frequency fan, which has lower rotation speed and less noise than the ordinary fan under the premise of generating the same air volume. On the pipeline, the liquid pressure generated when the refrigerant flows from the large-diameter pipeline to the small-diameter pipeline is reduced by gradient decompression, so as to avoid noise caused by excessive eruption pressure.

on the compressor, this refrigerator is also adjusted. By using the shock-absorbing and low-rebound damping foot pads, the noise generated by the compressor during starting, stopping and running is reduced, thus reducing the noise value of the whole machine.

due to TCL's structural optimization in the above three aspects, the noise of this 46P6-U refrigerator was finally controlled to 33 decibels, creating the lowest new standard in the industry.
