Abstract

The invention relates to a refrigeration compressor component improvement technology and discloses a multi-channel air suction mute cavity. The multi-channel air suction mute cavity comprises an uppermute chamber, a lower mute chamber and a communicating mechanism, wherein the communicating mechanism is mounted between the two chambers. An air outlet is formed in the upper mute chamber, and an air inlet is formed in the lower mute chamber. The multi-channel air suction mute cavity is characterized in that the communicating mechanism is designed to be provided with a main communicating channeland multiple subsidiary communicating channels. According to the multi-channel air suction mute cavity, the communicating mechanism is additionally provided with a communicating pipe, so that noise at different frequency bands are reduced; and the energy efficiency ratio of a compressor can be increased, and the noise of the compressor can be reduced.

Description

technical field [0001] The invention relates to the component improvement technology of a refrigerating compressor, in particular to a multi-communicating pipe suction muffler cavity for a fully enclosed reciprocating piston refrigerating compressor. Background technique [0002] At present, in the fully enclosed refrigeration compressors used in refrigerators (freezers), the generally used suction muffler chamber is composed of an upper quiet room, a lower quiet room and a communication mechanism installed between the two rooms. In the traditional suction muffler chamber The connecting mechanism of the compressor is designed as a single connecting pipe structure, which is easy to design and manufacture. According to the displacement of the compressor, the appropriate diameter of the connecting pipe can be selected. In general, in order to achieve a higher energy efficiency ratio, a larger aperture will be selected appropriately. However, when the displacement of the compre...
