1. A mechanical seal assembly, comprising: a rotating seal ring and a stationary seal ring, which define a sealing gap therein between wherein the rotating seal ring is free of holes; a shaft bush, on which the rotating seal ring is arranged; a carrier ring having at least one connecting opening, wherein the carrier ring is arranged on the shaft bush and at least partly covers the rotating seal ring on the outer circumference thereof; a first O-ring and a second O-ring, which are arranged between the rotating seal ring and the carrier ring and define an interspace on the outer circumference of the rotating seal ring between the carrier ring and the rotating seal ring; and the at least one connecting opening connects the interspace to an outer circumferential surface of the carrier ring. 2. The assembly according to claim 1, wherein multiple connecting openings are provided. 3. The assembly according to claim 2, wherein the connecting openings are arranged along the circumference of the carrier ring on a joint circular line, or that the connecting openings are arranged in different planes on the carrier ring. 4. The assembly according to claim 1, wherein the connecting openings are configured to be cylindrical with identical or different diameters, and/or tapering, particularly conically tapering and/or stepped and/or as elongated holes. 5. The assembly according to claim 1, wherein a central axis of the connecting openings is arranged at an angle (α1, α2) of less than 90°, particularly between 45° and 65°, and preferably about 55°, relative to a tangent T on the outer circumference of the carrier ring. 6. The assembly according to claim 5, wherein the central axes of two neighboring connecting openings define an angle β of about 90°. 7. The assembly according to claim 6, wherein two neighboring connecting openings intersect each other on an inner circumferential surface of the carrier ring. 8. The assembly according to claim 1, further comprising a groove which is provided on an outer circumferential surface of the carrier ring and connects the connecting openings on the outer circumferential surface of the carrier ring. 9. The assembly according to claim 1, further comprising a clamping ring which is radially arranged within the shaft bush. 10. The assembly according to claim 1 the carrier ring in axial direction (X-X) is longer than the shaft bush. 11. The assembly according to claim 1, wherein the rotating seal ring, the shaft bush, the carrier ring and the first and second O-ring form a subassembly which can be preassembled. 12. A method for using the mechanical seal assembly of claim 1.
