Abstract
A compressor includes two parallel arranged primary cylinders and a secondary cylinder arranged in the downstream of the two primary cylinders. The secondary cylinder includes a cylinder body and a sliding vane. The sliding vane is arranged inside the cylinder body. A locking part is used for locking and unlocking the sliding vane. The locking part is clamped with and separated from the sliding vane. When the sliding vane is in the locking position, the sliding vane is locked in a seal cavity inside the secondary cylinder, and the locking end of the locking part extends to the side at which the secondary cylinder is located. 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. An air conditioning system and compressor control method are also disclosed.
