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

Abstract: An indoor unit of an air-conditioning apparatus includes a casing with air inlet and air outlet. A heat exchanger in the casing exchanges heat with air sucked through the air inlet, an air-sending fan blows the heat exchanged air through the air outlet, and a vertical air-directing plate in the air outlet sets a vertical air flow direction in which the heat exchanged air is blown. The casing has a front panel, a bottom panel, and a forward-facing panel connected to the bottom panel at an angle. The air outlet extends from the bottom panel to the forward-facing panel; a lower corner at which joins the bottom panel and an air-outlet side walk; and a forward-facing corner joins the forward-facing panel and the air-outlet side wall. The lower corner and the forward-facing corner each have an edge removed. A forward-facing corner edge-removal dimension smaller than a lower corner edge-removal dimension.

Abstract: An indoor unit of an air-conditioning apparatus includes a casing having an air inlet, an air outlet, a front panel disposed to a front surface, a bottom panel disposed to a bottom surface, and a forward-facing panel disposed under the front panel and connected to the bottom panel at a right angle or an obtuse angle. The air outlet extends from the bottom panel to the forward-facing panel and includes a lower corner at which the bottom panel and an air-outlet side wall join together and a forward-facing corner at which the forward-facing panel and the air-outlet side wall join together. The lower corner and the forward-facing corner each have an edge removed to have an edge-removal dimension of the forward-facing corner that is smaller than an edge-removal dimension of the lower corner.
