PURPOSE:To achieve a tolerance in the execution of construction by a method wherein a suction air path and a blowoff path are made of a low heat conducting film material as flexible duct while an inner layer thereof is shaped in a honeycomb free to expand with the space of the inner layer as air layer. CONSTITUTION:An air suction path 14 and first and second blowoff paths 15 and 16 are built free to expand and in a flexible duct structure between the body 10 of an air conditioning apparatus set in a ceiling A and a face panel 6 set on the undersurface of the ceiling A. The material composing the ducts 14, 15 and 16 employs a film material having a low heat conductivity and in a cross-section structure, a duct layer is shaped in a honeycomb with the inside thereof as air layer. This can improve heat insulating property and allows the using of even a blowoff duct to prevent dew formation in cooling, especially by making the suction air and blowoff air cross inside and outside the duct. |
