A compressor and an air conditioning system. The compressor includes two compressing structures and an intermediate gas supplement structure. A communication pipe is provided between a gas exhaustion port of one compressing structure and a gas suction port of another compressing structure in the two compressing structures. The intermediate gas supplement structure is in communication with the communication pipe. At least one compressing structure is provided with a gas supplement structure. In the compressor and the air conditioning system, the gas supplement structure is provided to at least one compressing structure, so that at least two levels of gas supplement to the compressor are provided.

Compressor and air conditioning system

The present disclosure provides a compressor and an air conditioner. The compressor includes a housing; a first rotating shaft mounted in the housing; a connecting assembly sleeved on the first rotating shaft; and a first rotor assembly including a first rotor and a second rotor coaxially disposed on the connecting assembly. The connecting assembly carries the first rotor and the second rotor to rotate about the first rotating shaft together. The connecting assembly is configured to limit the relative positions of the first rotor and the second rotor, such that there exists a clearance between the first rotor and the second rotor. The present disclosure can maintain a clearance between the first rotor and the second rotor without increasing the number of components of the compressor.

Disclosed are a silencer and a compressor with same. The silencer includes a housing, a gas inlet end of the housing being provided with a protrusion extending into an interior of the housing, a portion of the protrusion approximate to a gas outlet end of the housing being closed, and the gas inlet end of the housing being provided with at least two gas inlets around the protrusion. A part of a gas flow enters the housing through the gas inlets, and other part of the gas flow impacts the protrusion and then at least partially flows back and enters the housing through the gas inlets.

An exhaust assembly and a compressor including the exhaust assembly. The exhaust assembly includes an exhaust bearing seat; an intake cavity is provided at an intake end of the exhaust bearing seat; an exhaust cavity is provided at an exhaust end of the exhaust bearing seat; the intake cavity and the exhaust cavity are staggered with each other in the axial direction of the exhaust bearing seat; the exhaust bearing seat is provided with a flow passage for connecting the intake cavity with the exhaust cavity; and an oil separation structure is provided in the exhaust cavity.

The present disclosure is related to a slide valve, a slide valve adjustment mechanism and a screw compressor. The slide valve includes a static slide valve and a moving slide valve, wherein the static slide valve is fixedly installed in a slide valve cavity and provided with an axially-penetrating valve hole; a plurality of bypass holes communicating with the valve hole () are formed in the sidewall of the static slide valve, and an exhaust port is formed in the sidewall of one end of the static slide valve. The slide valve may avoid scraping between the slide valve and a screw rotor and the slide valve cavity. Gaps between the slide valve and parts which cooperate with same are reduced, so that the leakage is reduced while the energy efficiency of the compressor is increased.

Disclosed is a multi-stage compressor, including a gas supplement structure, a low-pressure stage chamber and a high-pressure stage chamber. The gas supplement structure includes a gas supplement inlet and a perforated member wherein the gas supplement inlet is arranged at an upstream location of an exhaust gas flow of the low-pressure stage chamber; the perforated member is arranged at a downstream location of the exhaust gas flow of the low-pressure stage chamber; a liquid refrigerant sprayed from the gas supplement inlet is mixed with exhaust gas of the low-pressure stage chamber to impact on the perforated member; the liquid refrigerant is dispersed, the dispersed liquid refrigerants are re-mixed with the exhaust gas of the low-pressure stage chamber and enter the high-pressure stage chamber.

Multi-stage compressor and air conditioner

Disclosed are an oil separation structure and a compressor. The oil separation structure includes a housing and a filtering screen. A core is disposed at a center of the housing, and a plurality of guiding members for guiding gas flow are provided along circumferential directions of the core. The filtering screen is disposed on a periphery of the housing, and a cavity is formed between the filtering screen and the core. The housing is provided with a gas inlet and a gas outlet which are in communication with the cavity, and the gas inlet is configured to introduce the gas flow into the cavity; the guiding members are configured to guide the gas flow to rotationally flow around the core, and the gas outlet is configured to discharge the gas flow from the cavity.
