For this reason, the number of parts is large, the structure is complicated, and in the case of a large-scale structure, the number of air conditioning boxes increases, resulting in high costs and a great deal of labor for installing the damper. there were. More specifically, for example, as shown in FIG. 6, air (air supply) that has passed through an air conditioner is conveyed from the air supply duct 101 and installed on the ceiling of a living room space through a large number of air conditioning boxes 100. The case where it blows out from the blower outlet (anemo) V is demonstrated. In this case, it is necessary to install the damper VD at the inlet (upstream side of the air conditioning box 100) from the air supply duct 101 to the air conditioning box 100. Thus, when many air conditioning boxes 100 are installed, it is necessary to install and adjust the same number of dampers VD as the number of ducts connected between the ducts and the air conditioning boxes 100, which requires a lot of labor. It was a thing. In addition, material costs are also high.
