Disclosed are an oil separation device () and a condenser (-) with an oil separation function, and a refrigeration system () using same. The oil separation device () or the condenser (-) comprises: a shell () comprising an oil separation cavity (), a first refrigerant inlet (), a second refrigerant inlet (), a first flow guide channel (-), and a second flow guide channel (-), wherein refrigerant gas flowing through the two flow guide channels can be mixed. When the refrigeration system () comprises two compressors () with different displacements, the requirement of filtering and separating a gaseous refrigerant and lubricating oil can be met without the need for designing the size of the oil separation cavity () in accordance with large-displacement compressors (), and the size is small.

The present application provides a slide valve, wherein the slide valve is configured to regulate a load of a twin-screw compressor. The slide valve comprises a slide valve body, wherein the slide valve body has a connecting end and a free end, the connecting end is configured to connect to a slide valve connecting rod of the twin-screw compressor, and the slide valve is driven to slide by the slide valve connecting rod. A cavity is formed in the free end of the slide valve body, and the slide valve has a passage configured to fluidly couple the cavity with an external fluid to reduce air flow pulsations on a suction side of the twin-screw compressor and thereby reduce overall air flow pulsations in the twin-screw compressor.
