1. A refrigerator unit for an inflight service cart, which comprises; a thermal conductor having a first part and a second part,an insulated casing sized to fit within the inflight service cart, said insulated casing having grooves for releasably affixing the thermal conductor, anda refrigerant chamber inside the insulated casing,wherein, when the thermal conductor is releasably affixed to the insulated casing, the first part of the thermal conductor is in direct thermal contact with the refrigerant chamber and the second art of the thermal conductor is in direct thermal contact with an external space of the insulated casing. 2. Refrigerator unit according to claim 1, wherein the thermal conductor is a thermally conductive plate bent into an L shape, the sides of which L form the first and the second parts. 3. Refrigerator unit according to claim 1, wherein at least one surface of at least one part of the thermal conductor is insulated. 4. Refrigerator unit according to claim 1, wherein the second part of the thermal conductor and the surface facing towards the rear wall of the service cart in the operating state of the chilling part are insulated. 5. Refrigerator unit according to claim 1, wherein the insulated casing is of foam polypropylene. 6. Refrigerator unit according to claim 1, wherein the insulated casing is of a porous insulating material and foam polypropylene. 7. Refrigerator unit according to claim 1, wherein the insulated casing is equipped with an opening arrangement, in such a way that, in the operating state, the evaporation of the refrigerant is restricted in such a way that total evaporation takes place at the earliest within 13 hours. 8. Refrigerator unit according to claim 1, wherein the insulated casing comprises installation grooves that, in order to install the thermal conductor as a cover for the casing to close the refrigerant into the refrigerant chamber, in which case the second part of the thermal conductor acts as a chilling surface. 9. Refrigerator unit according to claim 1, wherein carbon-dioxide ice is used as the refrigerating material. 10. Refrigerator unit according to claim 1, wherein the insulated casing is sized to fit into inflight service carts manufactured according to both the KSSU and ATLAS dimension standards. 11. Refrigerator unit according to claim 1, wherein the thermal conductor is formed of two parts connected to each other very well thermally. 12. Refrigerator unit according to claim 1, wherein the insulated casing is formed of two parts connected thermally tightly to each other. 13. An inflight service cart comprising; a refrigerator unit which is independently detachable from the inflight service cart, wherein the refrigerator unit comprises: a thermal conductor having a first part and a second partan insulated casing sized to fit within the inflight service cart, said insulated casing having grooves for releasably affixing the thermal conductor, anda refrigerant chamber inside the insulated casing,wherein, when the thermal conductor is releasably affixed to the insulated casing, the first part of the thermal conductor is in direct thermal contact with the refrigerant chamber and the second part of the thermal conductor is in direct thermal contact with an external space of the insulated casing. 14. The Refrigerator unit according to claim 1, wherein the refrigerant chamber is surrounded by the insulated casing and the thermal conductor. 15. The Refrigerator unit according to claim 14, wherein the refrigerant chamber is configured such that, when in an operating state, air can escape from said refrigerant chamber. 16. The Refrigerator unit according claim 1, wherein the refrigerant chamber is configured such that release of cold air is regulated.
