Abstract

The invention provides a compressor and an air conditioning system. The compressor comprises a pump body and an air inlet assembly, and the pump body comprises a crankshaft and an air cylinder; the air inlet assembly comprises a filter part, an air inlet pipe, a header pipe and a branch pipe, wherein the air inlet pipe, the header pipe and the branch pipe are sequentially connected, the filter part is arranged in the air inlet pipe, and the branch pipe communicates with an inlet of the air cylinder. By adopting the scheme, a liquid separator in a traditional compressor is replaced with the air inlet assembly, the air inlet pipe, the header pipe and the branch pipe are all tubular parts, and the diameter is greatly reduced compared with the diameter of the liquid separator; in this way, the resonance point of a refrigerant air inlet flow path can be effectively improved, the total noise value in a low-frequency band is reduced, the diameter of the header pipe is greatly reduced compared with that of the traditional liquid separator, the sound radiation area is reduced, and therefore radiation noise is reduced; and meanwhile, the pressure pulsation of fluid turbulence in a large space of a liquid separator component is eliminated, so that the fluid noise during the operation (especially high-frequency operation) of the compressor can be effectively reduced. And therefore, through the scheme, the noise of the compressor can be reduced under the condition that the performance of the compressor is not influenced.

Description

technical field

[0001] The invention relates to the technical field of compressors, in particular to a compressor and an air conditioning system. Background technique

[0002] With the continuous improvement of the capacity range and miniaturization requirements of refrigeration systems, variable frequency rotary compressors have gradually been widely used due to their simple structure, relatively low cost, and high energy efficiency. In response to market demand, the core competitiveness of rotary compressors lies in broadband application of technology. With the continuous improvement of miniaturization and high-speed requirements, the noise level of the compressor will face severe challenges. For example, the noise of the compressor within 1500 Hz will increase significantly due to the influence of the natural frequency of the liquid separator part when it is running at high speed. It is difficult to achieve the noise reduction effect through the existing technical means....
