The invention discloses a compressor and heat exchange equipment. The compressor comprises n stages of compression assemblies and an air supplementing assembly, wherein the n stages of compression assemblies communicate to form a compression structure in a matched mode, and n is larger than or equal to 2; the air supplementing assembly comprises an air supplementing piece, and air supplementing holes are formed in the air supplementing piece; and an air outlet of the nth-stage compression assembly communicates with an air inlet of the at least one stage of compression assembly through the airsupplementing holes, and the extension trend of the air inlet of the compression assembly communicating with the air supplementing holes is kept consistent with the extension trend of the air supplementing holes. A refrigerant discharged along an air outlet of the nth-stage compression assembly communicates with the air inlet of the at least one stage of compression assembly through the air supplementing holes, the surge phenomenon, caused by flow reduction, of the compressor is avoided, and the extension trend of the air inlet of the compression assembly communicating with the air supplementing holes is kept consistent with the extension trend of the air supplementing holes, so that when air is supplemented through the air supplementing holes, and enters the air inlet of the compression assembly along the air supplementing holes, the air circulation resistance can be reduced, and then the pressure loss caused by the resistance is reduced.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor and heat exchange equipment. Background technique [0002] The magnetic levitation centrifugal compressor is a compressor that does not need lubricating oil. The permanent magnet motor rotor, drive shaft, and centrifugal impeller in the magnetic levitation centrifugal compressor are all held up by the magnetic force field of the electromagnetic bearing, and are in a position without direct contact. Suspension state, thus eliminating mechanical friction, so the efficiency loss, vibration and noise of the magnetic levitation centrifugal compressor are small. [0003] The magnetic levitation centrifugal refrigeration unit adopts frequency conversion speed regulation to adjust the cooling capacity of the unit, which has a very large range of cooling capacity adjustment. Generally, the magnetic levitation centrifugal refrigeration unit can realize stepless adjustment ...
