Embodiment Construction

[0026] Embodiments described herein provide a galley cart for use in a transportation vehicle that includes a seal assembly having a hollow stem seal positioned between the cart housing and the cart housing. between the doors of the car. The stem seal is coupled to any suitable location on the housing or door. In one embodiment, the stem seal is positioned vertically along an edge of the door opposite the hinge of the door. A stem seal defines a hollow cavity, and two end caps coupled to the seal further enclose the cavity. At least one of the end caps includes at least one aperture; however, the end cap(s) may include any suitable number and / or arrangement of apertures.

[0027] When the cart door is opened, the stem seal expands and draws gas through the holes into the seal cavity. Therefore, when the cart door is opened, the deployed stem seal passes the CO 2 Gas and possibly other gases are drawn into the cavity (CO 2 The gas will be near the bottom of the cart due to...

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.

Description

technical field [0001] Embodiments of the present disclosure relate generally to galley cart systems for transporting vehicles, and in particular to collapsible bulb seals having one or more apertures for use in Collect CO when expanding from collapsed to expanded position 2 and emits CO when retracted from the deployed position 2 . Background technique [0002] Galley carts used for food service in transportation vehicles (eg, airplanes and trains) often require cooling to keep food and beverages at a cooler temperature than the vehicle's cabin. At least some known carts include or are connected to a refrigeration system (cooler) that provides cool air to the interior volume of the cart to cool the food / drink. However, the cooler is powered by the vehicle system, thereby reducing the amount of power available to the vehicle for propulsion, propulsion, etc. Thus, the cooler renders the vehicle's electrical power system inefficient. Further, such cooler systems add weigh...
