PURPOSE: To rapidly and accurately supply the optimum air volume to rooms to be air conditioned by obtaining the relationship among the air flowing pressure loss value of each branch duct set from the air flowing pressure in which the sum of the required air volumes of the rooms to be air conditioned is used as the air volume of a blower, the air volume of each branch duct from the calculated air flow loss coefficient and a damper opening. CONSTITUTION: Calculating means 23 calculates the total air volume of the required air volumes of rooms 1 to be air conditioned from the output result of thermostats 14 provided in the rooms 1 to be air conditioned, and calculates the air flow resistance coefficients of the branch ducts from the relation result between the air volume measured result and the air volume and pressure of a blower 5. Further, it calculates the air flow pressure loss value of each duct from the relation results between the required air volume of each room 1 to be air conditioner and the air volume and pressure of the blower 5. The opening of a damper 9 corresponding to the required volume of the room 1 to be air conditioned is obtained based on the air flow pressure of the duct and the air flow resistance coefficient of the duct of the calculated or set result. |
