Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these implementations do not limit the present invention, and changes in structure, method, or function made by those skilled in the art based on these implementations are all included in the protection scope of the present invention.

[0026] Please refer to Figure 1 to Figure 5 , the refrigerator refrigeration system 100 of the present invention comprises a compressor 1, a condenser 2, a capillary tube 3 and an evaporator 4 connected in sequence, and the output end of the evaporator 4 is connected with the input end of the compressor 1, thereby forming the refrigerator refrigeration system 100 of the present invention refrigerant circulation path. Due to the joint action of the compressor 1 and the capillary tube 3, the high pressure in the condenser 2 can be maintained, and the low pressure in the evaporator 4 can be maintained. The end a...

Abstract

A refrigerating system of a refrigerator comprises a compressor, a condenser, a capillary tube and an evaporator and further comprises a gradually-expanded tube. The outlet end of the capillary tube is inserted into and welded to one end of the gradually-expanded tube; the other end of the gradually-expanded tube is inserted into and welded to the inlet end of the evaporator. The outer face of the gradually-expanded tube is covered with a silencer, and a vacuum layer formed by vacuumizing is formed between the gradually-expanded tube and the silencer. According to the refrigerating system of the refrigerator, the spraying noise of refrigerants of the refrigerator can be reduced to the greatest extent.

Description

technical field [0001] The invention relates to a refrigerator refrigeration system, in particular to a refrigerator refrigeration system for reducing the spraying noise of refrigerant refrigerant in the refrigerator. Background technique [0002] With the improvement of people's living standards, more and more attention is paid to the noise of household appliances. The main noise sources of the refrigerator during operation are the noise caused by the compressor, the BPF and eddy current noise caused by the fan, the evaporator and the capillary interface. Spray noise a few parts. [0003] In terms of the total sound pressure level or sound power level, the current noise levels of mainstream refrigerator manufacturers are constantly improving, basically below 40dB, and the background noise of an ordinary room during the day is also above 50dB, according to the sound source Interference relationship, the overall noise level of the refrigerator will not affect customers. How...
