Specifically, the above-described distance, angle, and area information of the sensor device 20, the above-described distance, angle, and area information of the sensor device 30, and the heat source height and heat source angle information sensed by the sensor device 20 are described. Then, from the information on the height and the heat source angle of the heat source sensed by the sensor device 30, the heat source region is specified using the table shown in FIG. 9, and information representing a three-dimensional heat source distribution is generated.

The table shown in FIG. 9 is created for each combination of areas where the sensor devices 20 and 30 shown in FIG. 8 are installed. The table shown in FIG. 9 is created in advance by an air conditioner installer or user. The table shown in FIG. 9 is a table when the area of the sensor device 20 is area 4 and the area of the sensor device 30 is area 3. As shown in FIG. 9, the distance of the sensor device 20 is 500 cm, the angle is 30 °, the area is the area 4, the distance of the sensor device 30 is 500 cm, the angle is 30 °, and the area is In area 3, the height of the heat source sensed by the sensor device 20 is 150 cm, the heat source angle of the heat source sensed by the sensor device 20 is 45 °, and the height of the heat source sensed by the sensor device 30 is 150 cm. When the heat source angle of the heat source sensed by the sensor device 30 is 45 °, the heat source region is identified as, for example, the region a shown in FIG.
　次いで、室内機１０の制御部１０１は、ステップＳ１０９で生成された３次元の熱源分布を表した情報から得られる熱源が人Ｈのみか否かを判別する（ステップＳ１１０）。図１０は、本実施の形態１にかかる３次元の熱源分布を表した情報から得られる熱源の一例を説明するための図である。図１０に示すような３次元の熱源分布の場合、制御部１０１は、領域ａ、領域ｄおよび領域ｇの熱源は人の形に分布しているため、熱源は人Ｈであると判断することが可能である。人の形はあらかじめ定義されているものとする。図１０に示すような３次元の熱源分布の場合、制御部１０１は、領域ｍの熱源は矩形に分布しているため、熱源は人Ｈ以外の、たとえばテレビであると判断することが可能である。ステップＳ１１０では、たとえば、ステップＳ１０９で生成された３次元の熱源分布を表した情報から得られる熱源が矩形の熱源を含まない場合は、熱源が人Ｈのみと判別することができる。 Next, the control unit 101 of the indoor unit 10 determines whether or not the person H is the only heat source obtained from the information representing the three-dimensional heat source distribution generated in step S109 (step S110). FIG. 10 is a diagram for explaining an example of a heat source obtained from information representing the three-dimensional heat source distribution according to the first embodiment. In the case of the three-dimensional heat source distribution as shown in FIG. 10, the control unit 101 determines that the heat source is the person H because the heat sources in the areas a, d, and g are distributed in a human shape. Is possible. The shape of the person is pre-defined. In the case of the three-dimensional heat source distribution as shown in FIG. 10, the control unit 101 can determine that the heat source in the region m is a rectangle, for example, a television other than the person H. is there. In step S110, for example, when the heat source obtained from the information representing the three-dimensional heat source distribution generated in step S109 does not include a rectangular heat source, it is possible to determine that the heat source is only person H.
　ステップＳ１１０での判別の結果、３次元の熱源分布を表した情報から得られる熱源が人Ｈのみでないときは（ステップＳ１１０でＮｏ）、室内機１０の制御部１０１は、３次元の熱源分布を表した情報の補正を行う（ステップＳ１１１）。３次元の熱源分布を表した情報の補正は、３次元の熱源分布を表した情報から、人Ｈ以外の熱源と判断された情報を除く処理をいう。たとえば、図１０に示すような３次元の熱源分布の場合、制御部１０１は、３次元の熱源分布を表した情報において領域ｍの熱源を表した情報を除くように３次元の熱源分布を表した情報の補正を行う。 As a result of the determination in step S110, when the heat source obtained from the information representing the three-dimensional heat source distribution is not only the person H (No in step S110), the control unit 101 of the indoor unit 10 displays the three-dimensional heat source distribution. The represented information is corrected (step S111). The correction of the information representing the three-dimensional heat source distribution refers to a process of excluding information determined as a heat source other than the person H from the information representing the three-dimensional heat source distribution. For example, in the case of a three-dimensional heat source distribution as shown in FIG. 10, the control unit 101 displays the three-dimensional heat source distribution so that information representing the heat source in the region m is excluded from the information representing the three-dimensional heat source distribution. Correction of the information.
　ステップＳ１１０での判別の結果、３次元の熱源分布を表した情報から得られる熱源が人Ｈのみであるとき（ステップＳ１１０でＹｅｓ）、またはステップＳ１１１の後に、室内機１０の制御部１０１は、３次元の熱源分布を表した情報から得られる熱源が存在する領域から人Ｈが存在する領域を特定する（ステップＳ１１２）。たとえば、図１０に示すような３次元の熱源分布の場合、制御部１０１は、人Ｈが存在する領域は、領域ａ、領域ｄおよび領域ｇと特定する。 As a result of the determination in step S110, when the heat source obtained from the information representing the three-dimensional heat source distribution is only the person H (Yes in step S110), or after step S111, the control unit 101 of the indoor unit 10 A region where the person H is present is identified from a region where the heat source obtained from the information representing the three-dimensional heat source distribution is present (step S112). For example, in the case of a three-dimensional heat source distribution as shown in FIG. 10, the control unit 101 specifies the regions where the person H exists as the region a, the region d, and the region g.
　次いで、室内機１０の制御部１０１は、ステップＳ１１２で特定された領域が空調制御対象の領域となるように、風向を制御して、当該領域に室内機１０から送出される空気が供給されるようにして、人Ｈが存在する領域の空調制御を行って（ステップＳ１１３）、本処理を終了する。たとえば、人Ｈが存在する領域が、領域ａ、領域ｄおよび領域ｇと特定された場合、制御部１０１は、領域ｄが空調制御対象の領域となるように、風向を制御して、当該領域に室内機１０から送出される空気が供給されるようにする。 Next, the control unit 101 of the indoor unit 10 controls the air direction so that the area specified in step S112 becomes the air conditioning control target area, and the air sent from the indoor unit 10 is supplied to the area. In this way, air conditioning control is performed on the area where the person H is present (step S113), and this process is terminated. For example, when the region where the person H exists is specified as the region a, the region d, and the region g, the control unit 101 controls the wind direction so that the region d becomes a region targeted for air conditioning control, and the region Is supplied with air sent from the indoor unit 10.
　図６に示した空調制御のための処理によれば、室内機１０の設置位置に依存せずにセンサ装置２０を設置することができる。また、室内の任意の位置に設置されたセンサ装置２０からの２次元の熱画像を表した情報に基づいて、人Ｈの位置に応じた空調制御が行われる。センサ装置２０の位置が固定されていないため、センサ装置２０の設置位置を部屋の中の障害物などに応じてユーザが決めることができる。 According to the process for air conditioning control shown in FIG. 6, the sensor device 20 can be installed without depending on the installation position of the indoor unit 10. In addition, air-conditioning control according to the position of the person H is performed based on information representing a two-dimensional thermal image from the sensor device 20 installed at an arbitrary position in the room. Since the position of the sensor device 20 is not fixed, the user can determine the installation position of the sensor device 20 according to an obstacle in the room.
　図６に示した空調制御のための処理によれば、室内の任意の位置に設置されたセンサ装置２０およびセンサ装置３０からの２次元の熱画像を表した情報から生成される３次元の熱源分布を表した情報に基づいて、人Ｈが存在する領域が特定される。これにより、空気調和システム１では、３次元の熱源分布を表した情報が得られるため、人Ｈが存在する領域を精度よく特定することができ、人Ｈの位置に応じた空調制御を精度よく行うことができる。 According to the process for air conditioning control shown in FIG. 6, a three-dimensional heat source generated from information representing a two-dimensional thermal image from the sensor device 20 and the sensor device 30 installed at an arbitrary position in the room. Based on the information representing the distribution, the region where the person H exists is specified. Thereby, in the air conditioning system 1, since the information showing the three-dimensional heat source distribution can be obtained, the area where the person H exists can be specified with high accuracy, and the air conditioning control according to the position of the person H can be performed with high accuracy. It can be carried out.
