Abstract: A scroll compressor (2) includes a sealed housing (3); a compression unit (11), having a fixed scroll (12) and an orbiting scroll (13); a drive shaft (18) configured to drive the orbiting scroll (13) to move orbitally, the drive shaft (18) being capable of rotating about an axis of rotation; a synchronous reluctance motor (15) configured to drive the drive shaft (18) to rotate about the axis of rotation, the synchronous reluctance motor (15) comprising a rotor (16) coupled to the drive shaft (18) and a stator (17) disposed around the rotor (16), and the rotor (16) including a ferrite permanent magnet (23); a compressor control apparatus (31) configured to control the scroll compressor (2) to operate; a lubricating oil tank (27), formed in a bottom portion of the sealed housing (3); a heating apparatus configured to heat lubricating oil stored in the lubricating oil tank (27); and an oil temperature sensor (28) disposed in the lubricating oil tank (27).
