Claim:
1. A refrigerant condenser assembly for a motor vehicle air-conditioning system, comprising cooling tubes for conducting a refrigerant, two collecting tubes for fluidically connecting the cooling tubes, a collecting tank comprising an upper top wall, a lower base wall, a side wall, an inlet opening, an outlet opening, an outlet chamber, an inlet chamber, an ascending tube, a descending tube, and a tube piece wherein the tube piece comprises an upper sealing ring, a middle sealing ring, a lower sealing ring, and a tube piece wall, wherein the inlet chamber is bounded by the middle sealing ring, the lower sealing ring, the side wall, and the tube piece side wall, wherein the outlet chamber is bounded by the upper sealing ring, the middle sealing ring, the side wall, and the tube piece side wall, wherein the inlet opening introduces the refrigerant into the collecting tank, wherein the outlet opening discharges the refrigerant from the collecting tank, wherein the inlet opening and the outlet opening fluidically connect the collecting tank to one of the two collecting tubes or to the cooling tubes, wherein the outlet opening is arranged on a side of the outlet chamber, wherein the outlet chamber is connected to the ascending tube through a first hole in the tube piece wall, wherein an accumulator chamber for the refrigerant is formed within the collecting tank and outside the outlet chamber, the inlet chamber, the ascending tube, and the descending tube, wherein the inlet opening is arranged on a side of the inlet chamber, wherein the inlet chamber is connected to the descending tube through a second hole in the tube piece wall, wherein the cooling tubes comprise a superheat region for cooling a vaporous refrigerant, a condensation region for condensing the vaporous refrigerant, and a supercooling region for cooling a liquid refrigerant, wherein the supercooling region is formed above the superheat region and above the condensation region, wherein the height of the accumulator chamber is greater, than the spacing between the lower base wall and the inlet opening or the outlet opening, wherein the ratio of the sum of the volume measured in mm
