Scroll compressor and method for controlling scroll compressor

A scroll compressor, comprising:

• a sealed housing, the sealed housing being provided with a suction opening, and the suction opening being configured to supply refrigerant to be compressed to the scroll compressor;
• a compression unit, the compression unit being arranged in the sealed housing and being configured to compress refrigerant supplied by the suction opening, and the compression unit comprising a fixed scroll and an orbiting scroll;
• a drive shaft, the drive shaft being arranged in the sealed housing and being configured to drive the orbiting scroll of the compression unit to move orbitally, and the drive shaft being capable of rotating around an axis of rotation;
• a synchronous reluctance motor, the synchronous reluctance motor being arranged in the sealed housing and being configured to drive the drive shaft to rotate around the axis of rotation, the synchronous reluctance motor comprising a rotor, coupled to the drive shaft, and a stator disposed around the rotor, and the rotor comprising a ferrite permanent magnet;
• a compressor control apparatus, the compressor control apparatus being configured to control the operation of the scroll compressor;
• a lubricating oil tank, the lubricating oil tank being formed in a bottom portion of the sealed housing;
• a heating apparatus, the heating apparatus being configured to heat lubricating oil stored in the lubricating oil tank;
• and
• an oil temperature sensor, the oil temperature sensor being arranged in the lubricating oil tank.
