A temperature regulating device, a compressor and a compressor silencer

Abstract

The present invention relates to a compressor muffler, which includes an expansion chamber, and the compressor muffler also includes a sound-absorbing expansion pipe fixedly arranged in the expansion chamber, the sound-absorbing expansion pipe includes at least one sound-absorbing segment, and the sound-absorbing The segment includes a central expansion section and a constriction section located at both ends of the central expansion section, and the end of the constriction section is an opening structure communicating with the interior of the sound-absorbing expansion tube. The addition of the sound-absorbing expansion pipe effectively compensates for the limited defect of the single-expansion cavity sound-absorbing range. The compressor silencer also weakens the noise of the frequency band that the original silencer cannot eliminate, which effectively reduces the overall noise of the compressor exhaust, thereby It meets the higher requirements of users. The invention also discloses a compressor adopting the silencer of the compressor, and a temperature adjustment device adopting the compressor.

Description

technical field [0001] The invention relates to the technical field of compressor production, in particular to a temperature adjustment device, a compressor and a compressor muffler. Background technique [0002] In temperature adjustment equipment (such as air conditioners), the compressor is one of the essential core components. The compressor, the rolling rotor compressor is one of many compressors. In the rolling rotor compressor, the high-pressure refrigerant gas is discharged After the air port is discharged, it enters the inside of the muffler connected to the flange of the compressor. There is a muffler cavity inside the muffler. The expansion structure of the muffler can reduce part of the exhaust noise. [0003] Such as figure 1 As shown in , the silencer cavity in the existing muffler is a petal-shaped expansion cavity 01 as a whole, and the refrigerant gas discharged from the exhaust port expands rapidly in the expansion cavity 01, and the volume change can elim...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 As shown in , the silencer cavity in the existing muffler is a petal-shaped expansion cavity 01 as a whole, and the refrigerant gas discharged from the exhaust port expands rapidly in the expansion cavity 01, and the volume change can eliminate part of the exhaust noise; however, the current Some mufflers have only one expansion cavity 01, and the cavity mode of the expansion cavity 01 has been determined, so the expansion cavity 01 can only eliminate the air flow noise of a specific frequency, but cannot eliminate the noise of other frequency bands, which leads to compressor The overall noise of the exhaust is still loud
