PROBLEM TO BE SOLVED: To prevent any troubles in the next operation by changing the speed of the supply air by an opening/closing structure of a punching duct to circulate the airconditioned air so as to be blown into a space to be air conditioned to achieve the cooling operation in a short time. SOLUTION: The atmospheric condition of a space to be air-conditioned by the air-conditioning operation in the space to be air-conditioned, the dehumidifying operation by the sanitation after the air-conditioning operation is completed, the drying operation after the sanitation, and the subsequent cooling operation before the operation is started, and a composite air conditioner 20 is operated. The air-conditioning atmosphere of 60% in humidity is formed. The draft feeling of a worker is eliminated during the operation by using a same duct, the low-temperature air-conditioning operation is achieved by the low-speed air supply to prevent the germs or microorganisms from lowering or flying high, the dehumidifying, drying and cooling are completed by the high-speed air supply after the operation is completed during the night time when the operation is stopped, and any troubles can be prevented in the next operation. |
