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 (32) are configured to connect chiller supply air duct outlet ports (30) 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 (24,30) may be connected by a connection adapter (32,46), and return duct upper and lower portions (38,44) may be connected by a connection adapter (46), allowing the supply duct upper portion and the return duct upper portion to overlap. |
