Abstract:
1. A cooling system for cooling food on board an aircraft, comprising: a cooling circuit adapted to supply cooling energy to at least one cooling station, a first refrigerant circulating in the cooling circuit being selected such that the first refrigerant is convertible at least partially from the liquid to the gaseous state of aggregation on releasing its cooling energy to the at least one cooling station and subsequently convertible back at least partially to the liquid state of aggregation again by an appropriate pressure and temperature control in the cooling circuit; a refrigerant container which comprises a receiving space, the receiving space being located in an interior space of the refrigerant container and being intended for receiving the first refrigerant circulating in the cooling circuit, the receiving space of the refrigerant container being connected to the cooling circuit by a flow line for discharging the first refrigerant from the receiving space and by a return line for returning the first refrigerant into the receiving space; and a heat exchanger being located in the receiving space of the refrigerant container and allowing the passage of a second refrigerant therethrough and being adapted to remove heat from the first refrigerant received in the receiving space in the liquid and/or gaseous state of aggregation, in order to supercool the first refrigerant and/or convert it to the liquid state of aggregation.
