  • Publication number: 20230123181
    Abstract: An effect determining unit to specify a learning affected period during which room temperature is affected by a temperature controller and a learning unaffected period during which the room temperature is not affected by the temperature controller; a room-temperature-model generating unit configured to learn a state of an outdoor and room temperature in a learning unaffected period to generate a room temperature model indicating the relationship between the state and the room temperature; an unaffected-room-temperature estimating unit configured to estimate learning temporary room temperature, which is the room temperature presumed to be unaffected by the temperature controller, in the learning affected period by using a room temperature model; and a room-temperature-change-model generating unit configured to learn the room temperature and learning temporary room temperature in the learning affected period, to generate a room temperature change model indicating the change in the room temperature caused by the
