Abstract
Disclosed are an oil separation device (1283) and a condenser (130-1130) with an oil separation function, and a refrigeration system (100, 1200) using same. The oil separation device (1283) or the condenser (130-1130) comprises: a shell (201, 1301) comprising an oil separation cavity (315, 1315), a first refrigerant inlet (221, 1221), a second refrigerant inlet (222, 1222), a first flow guide channel (445-2145), and a second flow guide channel (446-2146), wherein refrigerant gas flowing through the two flow guide channels can be mixed. When the refrigeration system (100, 1200) comprises two compressors (108, 1208, 109, 1209) 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 (315, 1315) in accordance with large-displacement compressors (109, 1209), and the size is small.
