Title:
SCREW COMPRESSOR, AIR CONDITIONING DEVICE, AND VOLUME EFFICIENCY ADJUSTING METHOD FOR SCREW COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/104811
Kind Code:
A1
Abstract:
Disclosed are a screw compressor, an air conditioning device, and a volume efficiency adjusting method for the screw compressor. The screw compressor comprises a body (1), a female rotor (2), a male rotor (3) and an atomization structure, wherein the female rotor (2) and the male rotor (3) are both arranged inside the body (1) and engage with one another; and the atomization structure is arranged inside the body (1), and is used for spraying an atomization oil into a compression cavity (11) formed by the engagement of the female rotor (2) and the male rotor (3). The atomization oil can efficiently seal a triangular leakage region formed between the male rotor (3), the female rotor (2) and the body (1), and enables the leakage amount of a rotor working cavity at a low rotation speed to be less, thus improving the volume efficiency and energy efficiency of the compressor.
