A system for venting a CO2 sublimate from a galley cart, the system comprising:
- a first compartment configured to contain CO2 sublimate as a primary working fluid;
- a refrigeration compartment, the 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;
- a vent in flow communication with the refrigeration compartment and receiving CO2 sublimate therefrom;
- and
- a separate duct system in flow communication between the vent and a second system of a vehicle, said separate duct system configured for flow of the CO2 sublimate from the vent as an alternative processing fluid or working fluid in the second system.
