摘要： To provide an indoor unit of an air-conditioning apparatus that eliminates a possibility of condensation on a front panel without deteriorating a quality of design. The indoor unit of an air-conditioning apparatus includes a casing having a rear surface to be mounted to an indoor wall, an air inlet provided in the casing, an air outlet that opens to a bottom surface of the casing, a heat exchanger and an air-sending device each arranged in an air passage extending from the air inlet to the air outlet, and an up-down air-directing plate disposed and rotatably supported in the air outlet. The up-down air-directing plate covers the air outlet in an off state. In an on state, the up-down air-directing plate is rotated and adjusted in angle to adjust a direction of air blown from the air outlet in an up-down direction. The indoor unit further includes an auxiliary air-directing plate disposed along a longitudinal direction of the air outlet and a rotating shaft about which the auxiliary air-directing plate rotates in a front-rear direction of the casing. The rotating shaft is disposed inside the air outlet and on a side of a front surface of the casing. In the off state, the auxiliary air-directing plate is positioned above the up-down air-directing plate inside the air outlet such that a free end of the auxiliary air-directing plate opposite from one end of the auxiliary air-directing plate fixed to the rotating shaft is positioned closer to the rear surface than is the rotating shaft. In the on state, the auxiliary air-directing plate is rotated in a direction from the rear surface to the front surface of the casing, and the free end is protruded from the air outlet to an outside of the casing.

摘要： An air-conditioner (100) is provided with a refrigerant circuit (RC) and an indoor fan (10). The refrigerant circuit (RC) has a compressor (1), a first four-way valve (2), an outdoor heat exchanger (3), a first expansion valve (4), a second four-way valve (5), a third four-way valve (6), an indoor heat exchanger (7), and a second expansion valve (8), and is configured to circulate refrigerant. The indoor fan (10) is configured to send air to the indoor heat exchanger (7). The indoor heat exchanger (7) has a first heat exchange portion (7a) and a second heat exchange portion (7b). During a cooling operation, in the first heat exchange portion (7a) and the second heat exchange portion (7b), a flow of refrigerant with respect to a flow of air sent by the indoor fan (10) is a parallel flow. In a reheating dehumidification operation, in the first heat exchange portion (7a), the flow of refrigerant with respect to the flow of air is the parallel flow, and in the second heat exchange portion (7b), the flow of refrigerant with respect to the flow of air is a counterflow.

摘要： An air conditioner (10) includes a refrigerant circuit (13) and refrigerant. The refrigerant circuit (13) has a compressor (1), a condenser (2), a pressure-regulating valve (3), and an evaporator (4). The refrigerant is R32. The pressure-regulating valve (3) includes a flow path (33) causing the refrigerant flowing from the condenser (2) to flow to the evaporator (4), a pressure reference chamber (S2) partitioned from the flow path (33) and filled with inert gas, and a valve portion (34) disposed in the flow path (33). The pressure-regulating valve (3) is configured to adjust a degree of opening of the valve portion (34) to adjust a flow rate of the refrigerant flowing through the flow path (33). The valve portion (34) is configured to increase the degree of opening when a pressure in the flow path (33) is higher than a pressure in the pressure reference chamber (S2), and reduce the degree of opening when the pressure in the flow path (33) is lower than the pressure in the pressure reference chamber (S2).

摘要： A propeller fan (100) includes a boss (1) provided on a rotation axis, and a blade (2) provided at an outer circumferential portion of the boss (1). The blade (2) includes a leading edge (23) and a trailing edge (24). The blade (2) includes a first area (51), a second area (52) located inward of the first area (51), and third areas (53) located outward of the second area (52). The third areas (53) are located inward and outward of the first area (51), with the first area interposed between the third areas (53). Each of the first area (51), the second area (52) and the third areas (53) includes at least one notch (25A, 25B, 25C, 25D) formed in the trailing edge (24). The notches (25A, 25B, 25C, 25D) satisfy the relationship "P1 >P2 >P3", where P1 is the width of the at least one notch (25A) in the first area (51), P2 is the width of the at least one notch (25B) in the second area (52), and P3 is the width of the at least one notch (25C, 25D) in each of the third areas (53).

摘要： An indoor unit for an air-conditioning apparatus includes a casing having an air inlet and an air outlet, an up-down airflow direction plate configured to be rotatably supported in the air outlet, and an auxiliary airflow direction plate configured to be rotatably supported at a position below the up-down airflow direction plate and on an upstream side of the up-down airflow direction plate. The up-down airflow direction plate has a main blade part formed of a flat plate and a rear edge part formed of a flat plate and formed on an upstream side of the main blade part. When the main blade part is in a horizontal state, the rear edge part is inclined upward to a back face of the casing from the main blade part. When an angle α represents an angle formed between the main blade part and the rear edge part and an angle ε represents an angle formed between the main blade part and a virtual line passing through a center of a tip part of the auxiliary airflow direction plate, the angle ε is greater than the angle α.
