PURPOSE:To enable efficient improvement of a feeling of comfort of a human body with effective power consumption by attaining simplification of a process of computation of a comfort index and reduction of the cost of an arithmetic device and also by controlling an air conditioner for a local environment in the vicinity of the human body by using the comfort index. CONSTITUTION:A comfort index at the time is computed by substituting values detected by a human body detecting means 4, a head skin temperature detecting means 5, an airflow velocity detecting means 6 and an airflow temperature detecting means 7 for an arithmetic formula of the comfort index Sh=V<1/2>(Th-Tv) [V: an airflow velocity (m/s) in the vicinity of the head (forehead), Th: the temperature ( deg.C) of the skin of the head (forehead), Tv: An airflow temperature ( deg.C) in the vicinity of the head (forehead)], by a comfort index computing means 3. Based on the result of the computation, the direction of the airflow is determined by executing the control of an airflow direction louver motor by the human body detecting means 4, and based on these data, subsequently, controls of a compressor operation frequency and an indoor fan motor are executed so that a space to be air-conditioned be within a comfortable sphere. The above-stated operations are executed again and the comfort index is computed. By the repetition of these operations, a comfortable space is produced constantly for a human body.
