Beschreibung
Zusammenfassung:	A compressor, an air-conditioning system and a compressor control method are disclosed. The compressor comprises two parallel arranged primary cylinders (10) and a secondary cylinder (20) arranged in the downstream of the two primary cylinders (10). The secondary cylinder (20) comprises a cylinder body (21) and a sliding vane (22). The sliding vane (22) is arranged inside the cylinder body (21). A locking part (30) is used for locking and unlocking the sliding vane (22). The locking part (30) is clamped with and separated from the sliding vane (22). When the sliding vane (22) is in the locking position, the sliding vane (22) is locked in a seal cavity inside the secondary cylinder (20), and the locking end of the locking part (30) extends to the side at which the secondary cylinder (20) is located. Because of setting of the locking part, the compressor can be switched between a single-stage mode and a double-stage mode. In the condition of light load, energy efficiency can be improved and the waste of energy sources is avoided.
