PROBLEM TO BE SOLVED: To reduce both static pressure in an air supply duct upstream of VAV (variable air volume) devices and conveying power. SOLUTION: An air conditioning system comprises the VAV devices 29a, 29b, 29c provided on the outlet side of the air supply duct 28 connected to an AHU (air handling unit) 1 through the air supply duct 6 and having small blowers 30a, 30b, 30c capable of regulating the rotating speed for supplying cold air 4 into an office 5; a pressure sensor 33 for detecting static pressure of the air supply duct 28; and a controller 34 controlling a blower 3 of the AHU 1 so that the measured static pressure of the pressure sensor 33 can maintain a constant value.
