Abstract

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.

Dependent claims

A method for operating a cooling system suitable for cooling food on board an aircraft, comprising:

discharging, upon starting the cooling system, a partial amount of a refrigerant, which, in a rest state of the cooling system, is stored in a receiving space of a refrigerant container in a gaseous state of aggregation, from the receiving space of the refrigerant container into a cooling circuit of the cooling system;
directing the partial amount of the refrigerant into a liquefier arranged in the cooling circuit and converting the partial amount of the refrigerant to a liquid state of aggregation;
directing the partial amount of the refrigerant liquefied by the liquefier through a heat exchanger arranged in the receiving space of the refrigerant container;
and
converting remaining refrigerant, stored in the receiving space of the refrigerant container in the gaseous state of aggregation, to the liquid state of aggregation by heat energy transfer to the partial amount of the refrigerant flowing through the heat exchanger.
