Abstract

The invention relates to a compressor and an air conditioning system. The compressor comprises an impeller, a diffusion flow channel and an air supplementing channel, wherein the impeller is used foraccelerating air entering the compressor, the diffusion flow channel communicates with an air outlet of the impeller, and is used for compressing the air entering the diffusion flow channel, and the air supplementing channel communicates with an air inlet of the diffusion flow channel and is used for supplementing the air into the diffusion flow channel. According to the compressor, the air supplementing channel communicating with the air inlet of the diffusion flow channel is arranged to introduce the supplemented air into the diffusion flow channel, when the compressor operates under partialloads, the pressure in the diffusion flow channel can be kept, the air separation condition can be improved, the surge can be effectively prevented, the compressor can normally run under the partialload working condition, so that the operation range of the compressor is expanded; and the structure of the way that surge is prevented through the air supplementation is simple, and manufacturing andmaintaining are convenient.

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] A centrifugal compressor is a device that uses a high-speed rotating impeller to work on a radially flowing refrigerant gas to obtain kinetic energy, which is then transformed into pressure energy after diffused flow. When the centrifugal compressor is working, the high-speed gas discharged from the impeller is diffused by the diffuser, and the kinetic energy is effectively converted into pressure energy, which becomes low-speed and high-pressure gas. [0003] There are two types of diffusers: vaneless diffuser and vaned diffuser. With the vaneless diffuser, the operating range of the compressor is relatively wide, but the aerodynamic performance of the design point is relatively low. The bladed diffuser can reduce the travel of the air flow in the diffuser channel, reduce friction and other losses, ...
