A refrigerating cabinet (1) comprises at least one goods presentation and air circulation space (2), a refrigeration cycle for cooling the at least one goods presentation and air circulation space (2), and at least one drain conduit (36; 42) configured for draining condensed water, which is produced when the refrigeration circuit is operating, from the at least one goods presentation and air circulation space (2). At least a portion of the at least one drain conduit (36; 42) is filled with a granulate material (34) or provided with a movable flap (48) allowing water to pass through the drain conduit (36; 42) and blocking air from passing through the drain conduit (36; 42).

1. A refrigerated sales cabinet comprising: a goods presentation and air circulation space for supporting refrigerated goods to be sold;an evaporator for cooling air flowing through the goods presentation and air circulation space; anda drain conduit connecting a bottom part of the goods presentation and air circulation space with a position outside of the goods presentation and air circulation space, said drain conduit being configured for draining condensed water forming within the goods presentation and air circulation space to a position outside of the goods presentation and air circulation space; wherein the drain conduit comprises an at least partially permeable container arranged along the flow path of the drain conduit, the container being filled with granulate material that is non-absorbent to water, and the granulate material being piled up within the container so as to occupy the diameter of the flow path such that air is hindered from passing through the drain conduit from outside of the goods presentation and air circulation space into the goods presentation and air circulation space and such that water still can pass through the drain conduit from the goods presentation and air circulation space to the position outside of the goods presentation and air circulation space. 2. The refrigerated sales cabinet of claim 1, wherein the drain conduit has a straight, non-bent shape and the longitudinal axis of the drain conduit forms an angle of 70 to 90° with the horizontal. 3. The refrigerated sales cabinet of claim 1, wherein the container being filled with granulate material forms a segment of the drain conduit. 4. The refrigerated sales cabinet of claim 3, wherein the container has a lower permeable wall onto which the granulate material is piled up. 5. The refrigerated sales cabinet of claim 1, wherein the container being filled with granulate material forms a cartridge positioned within the drain conduit. 6. The refrigerated sales cabinet of claim 5, wherein the drain conduit comprises a support, particularly a grid or an orifice, for supporting the container within the drain conduit. 7. The refrigerated sales cabinet of claim 1, wherein the container being filled with granulate material is formed as a net-bag positioned within the drain conduit. 8. The refrigerated sales cabinet of claim 1, wherein the fill level of the granulate material within in the container is at least 20 mm. 9. The refrigerated sales cabinet of claim 1, wherein the granulate material comprises elements having a rounded and/or smooth surface. 10. The refrigerated sales cabinet of claim 9, wherein the elements are of uniform size, the longest extension of the elements being in the range of 2 mm to 5 mm, particularly 3 mm approximately. 11. The refrigerated sales cabinet of claim 9, wherein the elements are of varying size, the longest extension of the elements being in the range of 2 mm to 5 mm. 12. The refrigerated sales cabinet of claim 1, wherein the granulate material comprises a plurality of pellets, particularly balls. 13. The refrigerated sales cabinet of claim 1, wherein the granulate material comprises at least one of glass, stone, gravel, plastics, polymer, silicium, or a metal material, particularly steel or aluminium.
