Here’s our guide to the must-have appliances for a cozy summer home.

In the everyday scenes of our lives, whether it is the bustling supermarket, the warm and convenient neighborhood convenience store, or the corner of your kitchen, the standing refrigerator is like a faithful guardian, quietly performing the duty of storing food and drink. However, as we immerse ourselves in the process of shopping or accessing our items, few of us will notice that these freezers can create a relatively quiet environment when they are operating efficiently. In fact, behind this hides a series of sophisticated noise reduction technology.

1.Noise reduction technology of compressor

As the core component of the vertical refrigerator, compressor is like the engine of the car, providing continuous power for the refrigeration cycle. However, the noise generated during the operation of the refrigerator has been a major problem in reducing the noise. In order to reduce the noise of the compressor, engineers from many aspects were optimized. In the structural design, the use of advanced computer simulation technology, the internal structure of the compressor for fine adjustment. By optimizing the fit clearance between piston and cylinder and improving the motion trajectory of crankshaft, the friction and vibration between moving parts are reduced, so as to reduce the noise from the source. In addition, the outside of the compressor wrapped with a layer of efficient sound insulation material, this sound insulation material can effectively absorb and block the compressor running noise, prevent its spread to the outside world.

2.Noise reduction technology of fan

The fans in the vertical freezer are responsible for facilitating the circulation of air and ensuring a uniform distribution of cold air to every corner. However, as the fan rotates, friction between the blades and the air causes noise. In order to achieve fan noise reduction, designers from the shape and material of the blade. The bionics principle is used to design the blade with special curved surface and angle, which makes the air pass through the blade more smoothly, reduces the formation of turbulence and Vortex, and reduces the noise. At the same time, the use of lightweight, high-strength materials to make blades, reduce the weight of the blade, reduce the inertia force when rotating, and further reduce noise. In the motor aspect, chooses the low noise, the high efficiency direct current brushless motor. The motor has the characteristics of stable rotating speed and small vibration, and can effectively reduce the noise of the fan in operation. In addition, by optimizing the installation position and angle of the fan, it makes the operation more stable and reduces the noise caused by vibration.

3.Noise reduction technology of refrigerant flow

In the process of refrigerant flow, if the flow rate is too fast or the pipeline design is unreasonable, it will produce noise. In order to reduce the noise of refrigerant flow, the technicians optimized the design of the piping system. Advanced fluid mechanics analysis software is used to accurately calculate the diameter, length and bending radius of the pipeline to ensure that the refrigerant can flow at a reasonable flow rate and pressure in the pipeline. At the same time, the special sealing structure and damping measures are adopted at the joint of the pipeline to reduce the noise caused by refrigerant leakage and vibration. In addition, the refrigerant charge on the precise control. Too much refrigerant will lead to high pressure in the pipeline and increase the flow noise, while too little refrigerant will affect the cooling effect. Through scientific calculation and accurate filling process, ensure the refrigerant in the pipeline in the best working condition, reduce noise.

4.Vibration transmission control technology

The vertical refrigerator will produce vibration in the process of operation, and these vibrations will be transmitted to the outside world through the components such as the shell, forming noise. In order to prevent the transmission of vibration, engineers have adopted a series of measures in the structural design of refrigerators. High-performance cushioning pads are installed on the bottom of the freezer. These pads have good elastic and damping characteristics, which can effectively absorb and cushion the vibration generated by the freezer during operation and reduce the transmission of vibration to the ground. At the same time, in the refrigerator shell and the internal structure between the use of elastic connectors, such as rubber pads, springs, etc. , to further isolate the transmission of vibration. In addition, the overall structure of the refrigerator is optimized to increase the rigidity and stability of the structure. Through the reasonable structure layout and the arrangement of the reinforcing ribs, the deformation and vibration of the refrigerator in the operation process are reduced, so as to reduce the noise.

Conclusion

The noise reduction technology of vertical freezer is the crystallization of modern science and Technology and engineering wisdom. From the Quiet Revolution of the compressor to the quiet optimization of the fan, from the smooth flow of the refrigerant to the damping protection of the overall structure, each technology embodies the efforts of the scientific researchers. It is these advanced noise reduction technology, so that the vertical refrigerator in providing us with convenient services at the same time, but also to keep quiet, into our living environment, for us to create a more comfortable, quiet living space.
