The utility model discloses a bipolar compression scroll structure which comprises a movable scroll and a fixed scroll which move in a meshed mode, and the movable scroll and the fixed scroll define two sections of relatively independent scroll lines including a first scroll line and a second scroll line. A second exhaust port and a first exhaust port are formed in the positions, located on the first scroll line and the second scroll line, of the fixed scroll respectively; a first air inlet is formed between the movable scroll and the fixed scroll, and a second air inlet is formed in the rear wall of the movable scroll; and gas flows into the first scroll line from the first gas inlet, then flows out through the second gas outlet, flows into the second scroll line from the second gas inlet, and finally flows out through the first gas outlet. The bipolar compression function is achieved, and the energy efficiency ratio is increased; and the working medium subjected to first-stage compression is output to an ex
