Abstract
A galley cart system employs a dry ice compartment and a refrigeration compartment in a galley cart in flow communication with the dry ice compartment. A ventilation system is in interruptible flow communication with at least the refrigeration compartment and configured to receive gas discharged from at least the refrigeration compartment.
Claims20
A method for dry ice cooling of a galley cart, the method comprising:
- removably docking the galley cart into a cart receiving area in a galley;
- sublimating dry ice in a dry ice compartment to form a cold CO2 sublimate;
- introducing the cold CO2 sublimate into a refrigeration compartment in the galley cart, the refrigeration compartment in flow communication with the dry ice compartment and located to receive downward gravity flow of the cold CO2 sublimate for cooling the refrigeration compartment;
- and venting the cold CO2 sublimate to a ventilation system by interconnection of the refrigeration compartment to a galley vent upon docking of the galley cart.

A method for dry ice cooling of a galley cart, the method comprising:
- removably docking the galley cart into a cart receiving area in a galley;
- sublimating dry ice in a first compartment configured to contain CO2 sublimate as a primary working fluid;
- employing the CO2 sublimate in a refrigeration compartment in flow communication with the first compartment and located to receive downward gravity flow of the CO2 sublimate as the primary working fluid providing refrigeration for food in the refrigeration compartment;
- venting the CO2 sublimate to a separate duct system in flow communication between a vent and a second system of a vehicle, said separate duct system configured for flow of the CO2 sublimate as an alternative processing fluid or working fluid in the second system upon docking of the galley cart;
- and employing the CO2 sublimate from the vent as an alternative processing fluid or working fluid in the second system.
