A scroll compressor

A scroll compressor including:

• a closed container,
• a scroll compression unit including:
• a first fixed scroll and a second fixed scroll defining an inner volume, the first fixed scroll comprising a first fixed base plate and a first fixed spiral wrap, the second fixed scroll comprising a second fixed base plate and a second fixed spiral wrap,
• an orbiting scroll arrangement disposed in the inner volume, the orbiting scroll arrangement including a first orbiting spiral wrap and a second orbiting spiral wrap, the first fixed spiral wrap and the first orbiting spiral wrap forming a plurality of first compression chambers, the second fixed spiral wrap and the second orbiting spiral wrap forming a plurality of second compression chambers,
• a drive shaft including a driving portion adapted for driving the orbiting scroll arrangement in an orbital movement,
• a driving motor arranged for driving in rotation the drive shaft about a rotation axis, the driving motor including a rotor coupled to the drive shaft and a stator, the first fixed base plate having a first face directed towards the driving motor and a second face opposite to the first face and directed towards the second fixed scroll,
• wherein the first fixed scroll includes at least one first discharge passage arranged to conduct, in use, the refrigerant compressed in the first compression chambers towards the driving motor, and
• wherein the orbiting scroll arrangement includes at least one communicating hole arranged to fluidly connect a central first compression chamber and a central second compression chamber.
