Refrigeration equipment and transition pipe for same

Abstract

The invention provides a transition pipe for refrigeration equipment. The transition pipe comprises an inlet section, a first silencer, a middle section and a second silencer, wherein a capillary pipe is inserted into the transition pipe via the first end of the inlet section; the first end of the first silencer is connected with the second end of the inlet section; the first silencer is used for attenuating the eruption sound generated when the capillary pipe carries out eruption; the first end of the middle section is connected with the second end of the first silencer; the first end of the second silencer is connected with the second end of the middle section; the second silencer is used for attenuating the eruption sound generated when the capillary pipe carries out eruption, which is transmitted by the middle section; and the transition pipe is integrally formed by the inlet section, the first silencer, the middle section and the second silencer. The transition pipe has the following advantages: the eruption sound generated when the capillary pipe carries out eruption can be effectively attenuated, thus being beneficial to reducing the whole noise value of the refrigeration equipment; vortex generated by turbulent flow formed on the walls of the jet pipe of the capillary pipe is avoided, thus reducing vibration of the walls of the refrigerant exciting pipe and reducing flow pulsation; and the production cost is low. The invention also provides the refrigeration equipment.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment design and manufacture, in particular to a refrigeration equipment and a transition pipe thereof. Background technique [0002] Along with the raising of people's living standard, refrigeration equipment such as refrigerator has become the necessity of people's daily life. When the refrigerator is cooling, the refrigeration compressor will inhale the low-temperature and low-pressure gas refrigerant from the evaporator, compress it into high-temperature and high-pressure superheated steam, and discharge it into the condenser. In the condenser, it dissipates heat to the surrounding air and becomes a high-pressure subcooled liquid. The high-pressure supercooled liquid flows into the capillary tube through the dry filter to throttle and reduce pressure, and becomes a low-temperature and low-pressure liquid state. It enters the evaporator to vaporize and absorb the heat of the surroundi...

AI Technical Summary

Problems solved by technology

but figure 1 and figure 2 The shown capillary 200' and transition tube 100' must adopt a transition reducer copper tube length of not less than 300 mm, resulting in higher production costs

[0004] and, figure 1 and figure 2 The shown capillary tube 200' and transition tube 100' have no obvious effect on reducing refrigerant turbulence sound. To suppress the turbulent flow in the core transition zone, a large area of ​​asphalt black damping material must be attached, but the cost of the pitch black damping material is relatively high
