  • An information processing device includes a temperature information acquisition unit to acquire a result of detecting temperature information in a region, a thermal distribution generation unit to generate thermal distribution information in the region from the temperature information, a reference thermal distribution generation unit to generate reference thermal distribution information in the region, and an air blow control unit to control an air blow setting so that a difference between the thermal distribution information and the reference thermal distribution information decreases.
  • the present disclosure by generating the thermal distribution information in the region from the result of detecting the temperature information in the region and controlling the operating status so that the difference between the thermal distribution information in the region and the reference thermal distribution information in the region decreases, it is possible to continuously control the operating status in consideration of the temperature conditions at the position for which a setting is made and in the vicinity of the position in cases where a setting has been made so as to locally provide a set temperature difference in the region, for example.
  • Fig. 1 is a block diagram schematically showing a configuration of an air conditioner according to the present embodiment.
  • the air conditioner 20 includes a temperature information acquisition unit 210, a thermal distribution generation unit 220, a setting information acquisition unit 230, a reference thermal distribution generation unit 240 and an air blow control unit 250. Further, the air conditioner 20 is communicatively connected to a temperature sensor 10 and a remote terminal 30. While the temperature sensor 10 is configured outside the air conditioner 20 in Fig. 1 , it is permissible even if the air conditioner 20 includes the temperature sensor 10 or is configured to be connected to a plurality of temperature sensors 10. Further, the connection between the temperature sensor 10 and the air conditioner 20 and the connection between the remote terminal 30 and the air conditioner 20 may also be implemented by wireless communication such as infrared communication or 5G communication or via a LAN network or the like.
  • the temperature sensor 10 detects temperature information in a region and supplies the detected temperature information in the region to the temperature information acquisition unit 210.
  • the region represents a spatial region equipped with the air conditioner 20 in which temperature and humidity are expected to be controlled by the air conditioner 20.
  • the air conditioner 20 is provided in a living room
  • the living room is the region. If the living room and a kitchen room spatially connect to each other and the temperature sensor 10 has been provided to be able to detect the temperature information in the kitchen room, the region may include the kitchen room.
  • the temperature information acquisition unit 210 acquires the temperature information in the region from the temperature sensor 10.
  • the thermal distribution generation unit 220 generates thermal distribution information in the region from the temperature information in the region acquired by the temperature information acquisition unit 210. For example, position information indicating detection target positions in the region as viewed from the temperature sensor 10 is converted into detection target positions in a virtual region representing a space in the region based on the temperature information detected at the detection target positions, and data obtained by plotting the detected temperature information at the positions in the virtual region is generated as the thermal distribution information. Further, from the data obtained by the plotting, it is also possible to execute interpolation in regard to other positions in the virtual region by using temperature information detected in the vicinity and use the data obtained by the interpolation as the thermal distribution information.

  • Fig. 2(a) shows an example of the thermal distribution information 40.
  • the thermal distribution information and the reference thermal distribution information respectively represent temperature information in regard to each point represented by two-dimensional coordinates in the region.
  • thermal distribution information having temperature information at each hollow circle position shown in Fig. 2(a) can be generated by converting a positional relationship in the virtual region determined based on the region by using the temperature information regarding m ⁇ n positions acquired from the temperature sensor 10.
  • the temperature information is indicated by a hollow circle at every position in Fig. 2(a)
  • the temperature information is represented by changing the color of each hollow circle based on the temperature. For example, when an image in which the blue color is intensified for lower temperature and the red color is intensified for higher temperature like a so-called thermography image, is presented to the user, it is possible to generate thermal distribution information facilitating a user to visually imagine the thermal distribution.
  • the thermal distribution generation unit 220 is capable of generating the thermal distribution information 40 by executing an interpolation process by using a temperature detection result in the vicinity.
  • the thermal distribution generation unit 220 is capable of generating the thermal distribution information 40 by executing the interpolation process by using a temperature detection result in the vicinity.
  • the thermal distribution generation unit 220 may be configured to execute the interpolation by using the temperature information from the temperature sensor 10 regarding the vicinity of the position. With such a configuration, even in cases where the temperature sensor 10 is a sensor that detects the temperature information at constant intervals, the thermal distribution generation unit 220 is capable of interpolating the temperature information in between by using a detection result in the vicinity.

  • the reference thermal distribution information can be generated so as to have thermal distribution in which the temperature gets closer to the set temperature as the position approaches the position for which the user made the setting.
  • the generation of the reference thermal distribution information may be executed by acquiring information such as the floor plan of the region and modifying the method of the interpolation based on the information, for example. Further, in consideration of limitation on the local temperature setting due to the performance of the air conditioner, when the user requests a setting beyond the performance of the air conditioner, the reference thermal distribution information is adjusted to implementable reference thermal distribution information.
  • the air blow control unit 250 receives the thermal distribution information from the thermal distribution generation unit 220 and the reference thermal distribution information from the reference thermal distribution generation unit 240 as inputs and controls an air blow setting so that a difference between the thermal distribution information and the reference thermal distribution information decreases.
