In a method for operating a cooling system for cooling food on board an aircraft, a partial amount of refrigerant, which, in the rest state, is stored in a receiving space of a refrigerant container in the gaseous state of aggregation, is discharged from the receiving space of the refrigerant container into a cooling circuit of the cooling system. The partial amount of the refrigerant is directed into a liquefier arranged in the cooling circuit and converted to the liquid state of aggregation. The partial amount of the refrigerant liquefied by the liquefier is directed through a heat exchanger arranged in the receiving space of the refrigerant container. The remaining refrigerant, stored in the receiving space of the refrigerant container in the gaseous state of aggregation, is converted to the liquid state of aggregation by heat energy transfer to the partial amount of the refrigerant flowing through the heat exchanger.
