Document Type and Number:

WIPO Patent Application WO/2017/016377

Kind Code:

A1

Abstract:

Disclosed is an oil separation barrel, which is provided with an oil separation and filtration structure (3) and comprises an oil separation cavity and an exhaust port (4). An exhaust airflow is filtered by the oil separation and filtering structure (3), then enters into the oil separation cavity, and finally is exhausted from the exhaust port (4). At least a part of the oil separation cavity is provided with two or more layers of circumferential walls. The exhaust airflow flows in the oil separation cavity in such a manner that it changes the advancedirection multiple times, can make a flow field uniform, and reduces noises and vibrations; and the exhaust airflow impacts an inner circumferential wall surface of the oil separation barrel multiple times, which can further improve the efficiency of oil separation. The oil separation barrel is provided in a screw compressor, and the screw compressor is provided in an air conditioning unit.
