Abstract
A galley cart system employs a housing with a door coupled to the housing, the door configured to be moved between a closed position and an open position. A vent plate in the housing communicates between a first compartment and a second compartment. A valve plate adjacent the vent plate is movable from a venting position when the door is in the closed position to a blocking position when the door is in the open position thereby preventing flow communication between the first and second compartment.
Claims15
A galley cart comprising:
- a housing defining a cavity;
- a door coupled to the housing, the door configured to be moved between a closed position and an open position;
- a plurality of vent plates in the housing to communicate between a sublimation volume and a plurality of refrigeration compartments;
- and
- a valve plate adjacent each vent plate, said valve plate movable from a venting position when the door is in the closed position to a blocking position when the door is in the open position;
- and wherein the sublimation volume includes a vertical distribution channel and a plurality of horizontal conduits, each horizontal conduit having an associated one of the plurality of vent plates and an associated valve plate.
A galley cart employing dry ice sublimation for cooling, said galley cart comprising:
- a housing defining a cavity;
- a door coupled to the housing, the door configured to be moved between a closed position and an open position;
- a dry ice storage compartment;
- a vertical distribution channel extending form the dry ice storage compartment;
- a plurality of horizontal conduits extending from the vertical distribution channel;
- a plurality of vent plates in the housing, each vent plate associated with a refrigeration compartment segment and in communication with an associated one of the plurality of horizontal conduits;
- a valve plate adjacent each vent plate, said valve plate movable from a venting position when the door is in the closed position to a blocking position when the door is in the open position, said venting position enabling sublimated CO2 flow from the associated horizontal conduit into the associated refrigeration compartment segment.
