摘要： There has been a problem of dew condensation, during a cooling operation, on a wind vane or the like provided at an air outlet because the wind speed of blown air leaking from ends in longitudinal direction of the air outlet is low, causing the entanglement of room air. Walls that form an air outlet from which air that has exchanged heat in a heat exchanger is blown are provided. End portions of each of the walls in a longitudinal direction of the air outlet have respective recesses such that a passage of the air therein is made wider than in a central portion of the wall. In the longitudinal direction of the air outlet, the recesses each have a downstream-side width that is smaller than an upstream-side width.

摘要： A blade front edge of a turbo fan has, between a main-plate-side blade front edge and a shroud-side blade front edge, a projecting blade front edge which distances away from a blade rear edge (located in a rotation direction A) as it furthers away from a main plate, which curves to a position away from a rotation center, and, in a range close to the main plate, a main-plate-side front-edge skirt portion which distances away from the blade rear edge and inclines away from the rotation center as it becomes closer to the main plate. On the other hand, a main-plate-side blade rear edge, which is a range close to the main plate of the blade rear edge, is substantially perpendicular to the main plate and a shroud-side blade rear edge, which is a range close to a shroud, is inclined so as to gradually distance away from the blade front edge (behind in the rotation direction A) as it furthers away from the main plate.

摘要： Body air outlets of an air-conditioning-apparatus indoor unit each has a substantially trapezoidal shape in plan view and are each defined by a body-air-outlet outer side wall, a body-air-outlet inner side wall, and a pair of body-air-outlet end walls. The body-air-outlet outer side wall is provided with a deflection guide at each of long-side ends thereof. The body-air-outlet end walls are each provided with a sloping guide. The deflection guide has a deflection-guide upper surface that gradually projects toward the body-air-outlet inner side wall in a direction toward a body open face (toward a downstream side) and in a direction toward the central part of the body air outlet. The sloping guide has a sloping-guide upper surface that gradually projects toward the central part of the body air outlet as the sloping guide extends closer to the body open face (toward the downstream side).
