Document Type and Number:
WIPO Patent Application WO/2019/169922
Kind Code:
A1
Abstract:
A screw compressor and an air conditioning unit. The screw compressor comprises a first pressure-level rotor assembly (1), a second pressure-level rotor assembly (2), and a machine body (3). The first pressure-level rotor assembly (1) comprises a first pressure-level male rotor (11) and a first pressure-level female rotor (12) meshed with each other. The second pressure-level rotor assembly (2) comprises a second pressure-level male rotor (21) and a second pressure-level female rotor (22) meshed with each other. The first pressure-level rotor assembly (1) and the second pressure-level rotor assembly (2) are configured to meet the following condition: the axial force applied by the internal compressed gas on the first pressure-level rotor assembly (1) is opposite to the axial force applied by the internal compressed gas on the second pressure-level rotor assembly (2), so that the screw compressor is stressed more evenly in the working process.
