UNIVERSAL MODULAR DUCTING FOR CHILLED AIRCRAFT GALLEYS

摘要

A universal modular ducting apparatus for chilled aircraft galleys for either air over or air through carts has modular primary supply and return duct assemblies. Outlet port connection adapters are configured to connect chiller supply air duct outlet ports to either air through or air over configurations of aircraft galley food carts. The supply and return duct assemblies are internally insulated, and may be made from thermoformed plastic, prepreg, or a carbon fiber reinforced composite. Supply duct upper and lower portions may be connected by a connection adapter, and return duct upper and lower portions may be connected by a connection adapter, allowing the supply duct upper portion and the return duct upper portion to overlap.

1. A universal modular ducting apparatus for chilled aircraft galleys including an aircraft galley ductwork assembly for chilling at least one aircraft galley food cart in at least one chilled galley food cart bay from a chiller unit, comprising:
a chiller supply air duct assembly configured to supply a chilled supply airflow to at least one aircraft galley food cart, said chiller supply air duct assembly including a chiller supply air duct lower portion having a chiller supply air inlet port configured to receive the chilled supply airflow from a chiller unit, a chiller supply air duct upper portion having at least one chiller supply air duct outlet port, each said at least one chiller supply air duct outlet port including an outlet port connection adapter configured to connect said at least one chiller supply air duct outlet port to said at least one aircraft galley food cart; and a chiller return air duct assembly configured to deliver a return airflow from said at least one aircraft galley food cart, said chiller return air duct assembly including a chiller return air duct upper portion having at least one chiller return air inlet port configured to receive a return airflow from said at least one aircraft galley food cart, each said at least one chiller return air duct inlet port including an inlet port connection adapter configured to connect said at least one chiller return air duct inlet port to said at least one aircraft galley food cart, and a chiller return air duct lower portion having a chiller return air outlet port configured to deliver the return airflow to the chiller unit for cooling of the airflow.
