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 are a screw compressor, and a gas conditioning apparatus and a refrigeration apparatus including the screw compressor. The screw compressor includes a body (10), in which a gas-supplement channel is provided, and the gas-supplement channel has at least two gas-supplement holes (201) communicated with a compression chamber. A number of the gas-supplement holes in the screw compressor is at least two. In a case that space available in the body (10) for disposing the gas-supplement holes (201) is limited, a hole diameter of each of the gas-supplement holes (201) is smaller. A larger number of gas-supplement holes (201) with smaller hole diameter are beneficial for reducing gas flow pulsation, thereby reducing noise in a gas-supplement process.
