Problems solved by technology

[0003] The existing reciprocating compressor has the advantages of reliable sealing, but its disadvantages of many valves, many parts, large vibration, poor liquid shock resistance, and poor high-speed frequency conversion greatly limit its scope of application, especially in the field of civil refrigeration and air conditioning
The structural features of the existing rotary compressors (such as rolling piston type, scroll type, sliding vane type, and swing rotor type) are stable operation, small vibration, and small size, but when used in high-pressure differential conditions, especially for CO 2 Poor sealing during transcritical cycle, resulting in serious leakage, low efficiency and increased energy consumption
[0004] In addition, whether it is a reciprocating, rolling piston, scroll or swinging rotor compressor,

Abstract

The present invention relates to a kind of compressor and expansion compressor capable of implementing multi-stage compression. Said compressor is characterized by that several working chambers are set in a ball cylinder, the air channel is set on the piston and piston hinge support, intake and exhaust channel is set on the cylinder body and cylinder cover, when the piston is rotated to all the working chamber and has need of intaking air and exhausting air, the correspondent air channel is communicated with intake and exhaust channel so as to implement multi-stage compression and expansion.

Description

technical field [0001] The invention relates to a compressor, in particular to a spherical compressor and an expansion compressor capable of realizing multistage compression. Background technique [0002] In many fields of civil, industrial and scientific research, compressors capable of multi-stage compression are required. The advantages of multi-stage compression are that it can achieve high pressure ratio, reduce working pressure difference, reduce leakage, increase volumetric efficiency, reduce exhaust temperature, improve lubrication conditions and improve reliability; in the field of refrigeration, in addition to the above advantages, multi-stage compression can also achieve more Efficient way of cryogenic refrigeration; in CO 2 In a transcritical cycle, multi-stage compression or multi-stage compression and expansion is the fundamental way to improve its cycle efficiency. [0003] Existing reciprocating compressors have the advantages of reliable sealing, but the d...
