Patent attributes
A galley refrigeration system is provided in which a galley cart is positioned in the cavity of a galley compartment comprising at least a cart-facing opening positioned in a vertically intermediate region of the back wall, the galley cart or the galley compartment having a duct-facing opening positioned adjacent to the cart-facing opening. A heat exchanger configured to generate cooling air is provided within the galley compartment, adjacent the vertically intermediate region of the back wall of the galley compartment defining the cavity. An air supply duct, provided at the cart-facing opening, is configured to guide the cooling air from the heat exchanger into the galley cart, and configured to be detachably coupled to the duct-facing opening of the cart or the galley compartment. An electronically actuated valve controls a variable flow rate of the cooling air from the air supply duct into the galley cart.
