DUCT TYPE AIR CONDITIONING SYSTEM AND DAMPER KIT THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a duct type air conditioning system and a damper kit therefore in which restriction on the damper installing position of a duct is relaxed while facilitating application of a heat insulating material or a sealing material thereto. SOLUTION: The damper kit 10 for duct type air conditioning system comprises a tubular duct 1 for conducting gas, and a damper having a rotary operating shaft part 2s and a damper body 2b disposed in the duct 1 and limiting the quantity of air conducting through the duct 1 through rotation of the rotary operating shaft part 2s. An opening 1a for damper is made at a part of the duct 1 corresponding to the rotary operating shaft part 2s. A tubular adapter 4 is arranged on the outer circumference of an inner tube 1 for coupling the duct while covering the inner tube 1 at a position corresponding to the opening 1a for damper. A damper drive motor 3 is contained in a space between the inner tube 1 and the adapter 4 and coupled removably with the rotary operating shaft part 2s.
