Abstract

The invention provides a silencing device and compression equipment. The silencing device comprises a silencing shell, wherein the silencing shell comprises a first silencing part and a second silencing part which are integrally formed, the first silencing part is provided with a first silencing cavity, the second silencing part is provided with a second silencing cavity, the first silencing cavity and the second silencing cavity are independently arranged, a first inlet and a first outlet which communicate with the first silencing cavity are formed in the first silencing part, a second inletand a second outlet which communicate with the second silencing cavity are formed in the second silencing part, and fluid sequentially passes through the first silencing cavity and the second silencing cavity. According to the silencing device, a two-stage compressor is subjected to two-stage noise reduction through the first silencing cavity and the second silencing cavity which are independentlyarranged, and compared with the mode that two independent silencers are adopted for two-stage noise reduction in the prior art, the silencing device is small in occupied space, high in space utilization rate and good in noise reduction effect, and therefore, the compressor equipment with the silencing device is small in occupied space.

Description

technical field [0001] The present invention relates to the technical field of compressor noise reduction, in particular to a noise reduction device and compression equipment. Background technique [0002] With the improvement of living standards and quality, more and more refrigerator systems have put forward application requirements such as independent temperature control, deep freezing below -33°C, and high energy efficiency. [0003] The independent temperature control of the refrigeration system can be realized by the independent temperature control of the multi-evaporation temperature system, that is, the refrigeration system needs to have multiple evaporation pressures, and the corresponding compressor also needs the function of multi-stage compression. [0004] For the deep freezing requirement below -33°C, refrigerants similar to R410a, R404a, R290 can be directly achieved by a single stage, but due to the physical properties of the refrigerant, it has not been wide...
