摘要： To provide an indoor unit of an air conditioning apparatus that can reduce the volume of air blown out from any air outlet of plural air outlets while suppressing dew condensation without using a new part. An indoor unit (4) of an air conditioning apparatus (1) that is fixed with respect to a ceiling is equipped with an indoor unit casing (31) that has an air inlet (35) and plural long-side air outlets (51 to 54). Plural flap bodies (80) are disposed in the plural long-side air outlets (51 to 54). The flap bodies (80) can, by rotating, adjust the airflow direction of conditioned air blown out from the long-side air outlets (51 to 54). A control unit (7) can independently adjust the rotational states of the plural flap bodies (80). The control unit (7) causes the entire body of at least any one of the plural flap bodies (80) to be positioned inside the corresponding long-side air outlet (51 to 54) to thereby reduce the volume of the conditioned air passing through the long-side air outlet (51 to 54).

摘要： An indoor unit (100) of the present invention includes: a casing (120) including a top plate (121) and lateral plates (122); a motor (180) mounted to a central part on an inner surface side of the top plate (121); a turbofan (170) fixed to a rotary shaft (181) of the motor (180) and configured to rotate through drive of the motor (180); a drain pan (140) received in the casing (120) and mounted to the lateral plates (122) of the casing (120); and a bellmouth (160) mounted to the drain pan (140) and configured to rectify a fluid flowing into the casing (120). The drain pan (140) includes a positioning fitting (143) having: a casing-fixing threaded hole (143a) for allowing the drain pan (140) to be fixed to the casing (120) with a screw; and a bellmouth-fixing threaded hole (143b) for allowing the bellmouth (160) to be fixed to the drain pan (140) with a screw.

摘要： On a second surface (72) of a louver (70) of an indoor unit (10), a plurality of grooves (G) recessed toward a first surface (71) side and extending in a direction crossing an air flow direction are provided side-by-side in the air flow direction. A peak of a groove depth (d) in the plurality of grooves (G) is present in a region on a leading edge (73) side in the louver (70). The groove depths (d) in the plurality of grooves (G) gradually increase from the leading edge (73) side toward a position of the peak of the groove depth (d) and gradually decrease from the position of the peak of the groove depth (d) toward a trailing edge side (74). The position of the peak of the groove depth (d) is provided in a region corresponding to a position of a peak of a blade thickness (T).

摘要： Occurrence of dew condensation on a design surface side of a louver (7) is inhibited even when an outlet air flow (12c) is blown in a substantially horizontal direction. An indoor unit (1) of an air-conditioner is provided with a casing (10), a decorative air panel (1b) provided on a bottom surface of the casing (10), a blower (8) and a heat exchanger (3) provided within the casing (10), an air inlet (2) for drawing an indoor air flow into the casing (10), an air outlet (4) for blowing an air flow into a room, and a louver (7) provided on the air outlet (4) for adjusting a wind direction of the outlet air flow (12c). The louver (7) having a cross-sectional shape formed of circular arcs (30, 31) with two or more curvature radii (R1, R2) is formed such that louver shape B/A is in a range of "B/A = 2 to 4" when an angle (A) between a tangent (32) at a louver tip end (7a) of the circular arc (30) forming a front side portion of the louver (7) and a level line (34) is set to A and an angle (B) between a tangent (33) at a louver rear end (7b) of the circular arc (31) forming a rear side portion of the louver (7) and the level line (34) is set to B in a fully-closed state of the louver (7).

摘要： In order to carry out, in a heating operation, an airflow rate adjusting operation in which a reduced amount of conditioned air is blown in one or more of a plurality of blowing directions to increase a blowing speed in the rest of the blowing directions, an operation control section (70) is configured to control the flow of the conditioned air such that the conditioned air is blown out in a horizontal blow mode in the blowing direction in which the blowing speed is increased by the airflow rate adjusting operation, and periodically change the blowing direction in which a reduced amount of the conditioned air is blown. As a result, temperature variations in the air-conditioning target space (R) in the heating operation are reduced.

摘要： In an indoor unit (13) installed on a ceiling, a filter (41) is arranged along an upper surface of a suction grille (28). The filter (41) is attached to a transfer belt (58), and moves as pulleys (56, 57) rotate. A rotating brush (51) is in contact with the filter (41). Dust trapped on the filter (41) is removed by the rotating brush (51) as the filter (41) moves. A dust container (60) is provided below the rotating brush (51), and the dust removed from the filter (41) accumulates in the dust container (60). The dust container (60) is attached to a suction grille (28) which can be lifted/lowered. When the suction grille (28) is lowered, the dust container (60) is lowered together with the suction grille (28).

摘要： A heat exchanger capable of improving the heat exchanging performance while suppressing the increase in the pressure loss is provided. A heat exchanger (1), in which a large number of plate-shaped fins (21) are attached to outer peripheries of heat transfer tubes (20) through which a refrigerant flows, the heat exchanger (1) being for performing heat exchange with the air. Three rows of heat transfer tubes (20a, 20b, 20c) are arranged along an air flow direction. Among the three rows of the heat transfer tubes (20a, 20b, 20c), an inlet side heat transfer tube in a case of using as an evaporator or an outlet side heat transfer tube in a case of using as a condenser has the smallest diameter. In a case where the most windward side heat transfer tube has the smallest diameter, a tube diameter of the most windward side heat transfer tube is D1, a tube diameter of the middle heat transfer tube is D2, and a tube diameter of the most leeward side is D3, D1
