Abstract

The invention provides refrigeration equipment. The refrigeration equipment comprises a box body, a compressor, an evaporator, a condenser and a capillary tube. The box body comprises a shell and an inner container, and a heat preservation layer is arranged between the shell and the inner container; a sunken cavity for mounting the compressor is formed in the bottom of the box body, and the compressor is located in the sunken cavity; and the refrigeration equipment further comprises a transition tube with a uniform section. The transition tube is connected between the capillary tube and the evaporator, and the capillary tube and the transition tube are located between the sunken cavity and the inner container. The transition tube with the uniform section is adopted, and speed reduction treatment is carried out on polaron injection noise generated by high-speed refrigerants output out of an outlet of the capillary tube and injection speed, so that the overall noise level of the refrigeration equipment is obviously reduced; the transition tube is of a uniform-section structure, so that the number of welding points is reduced, and the equipment is quite suitable for mass production; and in addition, due to the fact that the capillary tube and the transition tube are arranged between the sunken cavity and the inner container, the radiation acoustic emission direction of the capillary tube is changed, and the influence of the noise of the capillary tube on a user is reduced more effectively.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a refrigeration equipment. Background technique [0002] At present, refrigeration equipment (for example: refrigerators, freezers) is widely used in people's daily life. The refrigeration circuit in the refrigeration equipment usually consists of a compressor, an evaporator, and a condenser. A capillary tube is arranged between the evaporator and the condenser. During the operation of the refrigeration equipment, the refrigerant flows through the capillary due to the cross-section Variations will create noise. In order to reduce the noise generated by the capillary, in the prior art, a transition pipe with a variable cross-section or a transition pipe with a sudden cross-section is usually used to connect the capillary and the inlet pipe of the evaporator, so as to reduce the flow noise of the capillary. Specifically, the application number is 92103280.3, and the name is a refrigerato...
