Abstract: 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.

Abstract: 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.

Abstract: A housing structure including: a housing, a bottom of the housing being provided with a plurality of supporting feet; a supporting component disposed in the housing and configured to support a motor and a rotor of a compressor; and a connecting component, one end of the connecting component being connected to the supporting component, another end of the connecting component being connected to the housing, and a joint of the connecting component with the housing being away from the supporting feet. An air-conditioning unit and a compressor thereof are also provided.

Abstract: 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.

An air-conditioning unit and a compressor thereof are also provided. In the structure, vibration passes through a transmission path in the housing before reaching the supporting feet, reducing excessive compressor vibration. The transmission path of the vibration in the housing is extended, thereby reducing the vibration transmitted to a whole machine of the air-conditioning unit during operation, ensuring operational reliability of the whole machine.

Abstract: The present disclosure discloses a screw compressor and an air-conditioning unit, and relates to the field of compressors. The screw compressor has a first pressure level rotor assembly, a second pressure level rotor assembly and a body. The first pressure level rotor assembly has a first pressure level male rotor and a first pressure level female rotor; the second pressure level rotor assembly has a second pressure level male rotor and a second pressure level female rotor. Wherein, the first pressure level rotor assembly and the second pressure level rotor assembly are configured to enable an axial force received by the first pressure level rotor assembly and exerted by a compressed gas opposite to an axial force received by the second pressure level rotor assembly and exerted by a compressed gas. The force received during the operational process of the screw compressor is more balanced.

Abstract: Disclosed is a connection structure of an exhaust bearing seat for compressors and screw compressors, designed to solve the problem of large radial vibration of the existing exhaust-end bearing seat. The connection structure includes an exhaust bearing seat, an oil separation bucket, and an oil separation screen assembly all arranged at an exhaust end of a body of the compressor, wherein a tail end of the exhaust bearing seat is connected with the oil separation screen assembly, and an outer periphery of the oil separation screen assembly is provided with a vibration-reducing element, which is connected to an inner wall of the oil separation bucket. The vibration of the exhaust bearing seat is transmitted to the vibration-reducing element through the oil separation screen assembly, and then to the oil separation bucket after being absorbed and suppressed by the vibration-reducing element.
