PURPOSE:To permit to operate an air conditioner efficiently without using big ventilating energy by a method wherein a main duct, connected to the air conditioner, is provided with a plurality of branched ducts in parallel to each other and respective blow-off ducts are provided with dampers opened and closed separately with predetermined frequencies. CONSTITUTION:The damper 7 is consisting of principal parts such as a fixed louver 8, fixed to the internal wall surfaces of the blow-off ducts 5a-5f, 6a-6f, a rotary louver 9, located on the same center line along the surface of the fixed louver 8 and opening and closing the opening of the vixed louver 8, and a motor 10, rotating the rotary louver continuously with a predetermined speed. According to this method, the timing of opening and closing of the dampers 7 for respective blow-off ducts 5a-5f, 6a-6f in each branched ducts 3, 4 may be set so as to be opened and closed alternately, for example, therefore, the blow-off ducts 5a-5f, 6a-6f may be divided into two groups to effect the pulsation air- conditioning. In this case, the total flow amount of the air-conditioning air, blown off from respetive blow-off ducts 5a-5f, 6a-6f, is made constant at all times and it coincides with the capacity of the air conditioner 1 or the rating flow amount thereof. |
