Abstract: An air conditioning system and an air conditioning method are disclosed for quickly and effectively controlling the temperature in a room requiring cooling and keeping the room at a uniform temperature. The present invention estimates a temperature distribution in a room through a simulation and controls airflow rates and airflow directions of a plurality of fans on the basis of the simulation result. Temperature sensors are arranged at predetermined positions in a room such as a computer room. A simulation is performed on the basis of temperatures detected by the temperature sensor Sn and the current airflow rates and airflow directions of a plurality of fans to obtain a temperature distribution in the room. It is determined whether obtained temperatures are in a predetermined temperature range. As the result of such determination, at least one of airflow rate and airflow direction of a fan which covers a position being at a temperature out of the predetermined temperature range is controlled.
