An indoor unit for an air-conditioning apparatus includes a heat exchanger and an air-blowing device disposed upstream of the heat exchanger. The air-blowing device of the indoor unit includes a casing, a bellmouth disposed to an air inlet of the casing, a fan of one of an axial-flow type and a diagonal-flow type disposed within the bellmouth, a motor for rotating the fan, a motor base holding the motor, and a motor stay connecting the motor base to the bellmouth. The fan includes blades. The motor stay includes rod-shaped members. The motor stay of the air-blowing device is configured such that, in plan view, a downstream edge of each blade of the fan intersects any of the rod-shaped members of the motor stay irrespective of the angle of rotation of the fan.

In an indoor unit for an air-conditioning apparatus, a downstream edge of each of the blades of the fan of an air-blowing device, when viewed in plan view, intersects any of the members of a motor stay of the air-blowing device irrespective of an angle of rotation of the fan. The motor stays are connected to the mounting portions of a bellmouth in which the fan is disposed, wherein the mounting portions protrude downward from a downstream outlet end of the bellmouth and each include side surfaces, of which at least a first side surface opposing a pressure surface of each of the blades of the fan is at an angle relative to a rotation axis of the fan.

An outdoor unit for an air-conditioning apparatus includes a heat exchanger, at least one fan, a compressor, and a box-shaped casing that houses the foregoing elements and has an air inlet and an air outlet. The compressor is provided at a position outside an air passage in which air taken in from the air inlet flows through the heat exchanger and the fan toward the air outlet. The heat exchanger includes a plurality of heat exchanger segments. The heat exchanger segments are arranged zigzag.

To provide a multiblade fan that enables an improvement in noise characteristics or blowing performance. The multiblade fan includes a scroll type casing that has a bell-mouthed inlet and an impeller housed in the casing. The impeller includes a plurality of blades and a rotation axis m oriented toward the inlet of the casing. The blades are annularly arranged. In the multiblade fan, a center axis of the inlet and the rotation axis of the impeller are arranged at a tilt angle to each other and in any one of an intersecting positional relationship and a skew-lines positional relationship so that a space between the inlet and the impeller increases from the rotation axis of the impeller toward an outlet of the casing.

An outdoor unit for an air-conditioning apparatus includes at least a heat exchanger, a fan, a compressor, and a box-like casing housing these components and having an air inlet and an air outlet. The compressor is arranged at a location other than an air passage in which air having flowed in through the air inlet flows through the heat exchanger and the fan to the air outlet. The heat exchanger includes a plurality of heat exchange portions, and these heat exchange portions are arranged in a zigzag shape.
