摘要： A centrifugal blower includes a centrifugal fan having a main plate and a side plate facing each other in a direction of a rotation axis, and a casing to house the centrifugal fan. The casing has a peripheral wall extending along an outer circumferential edge of the centrifugal fan, and has a tongue portion at a position on the peripheral wall. A distance between the outer circumferential edge of the centrifugal fan and the tongue portion is smaller on the main plate side of the centrifugal fan than on the side plate side of the centrifugal fan.

摘要： An air conditioner includes: a heat exchanger housed inside a main body and arranged in a flow passage of air to be sucked into the main body through an air inlet and blown out to a target space through an air outlet; and an airflow-direction vane arranged at the air outlet. The airflow-direction vane includes a first curved portion and a second curved portion. The first curved portion is positioned on an upstream side with respect to the second curved portion, and a curvature of the first curved portion is larger than a curvature of the second curved portion.

摘要： An inner peripheral side of the blade with respect to an apex (P) of the leading edge protruding portion extends forward in the fan rotating direction with respect to the apex (P). A radius (Rq) at a position of an apex (Q) of the trailing edge protruding portion is larger than a radius (Rp) at a position of the apex (P). The radius (Rq) at the position of the apex (Q) is larger than an intermediate radius (Rm) between a radius (Ro) of an outer peripheral edge and a radius (Ri) of an inner peripheral edge.

摘要： Provided is an air conditioning apparatus, including: a main body having at least one air inlet and at least one air outlet each being formed at a lower part of the main body; and a heat exchanger housed inside the main body and arranged in a flow passage of air to be sucked into the main body through the air inlet and blown out to a target space through the air outlet. The air outlet is formed between a heat exchanger outlet-side air duct wall and an opposing air duct wall, which is opposed to the heat exchanger outlet-side air duct wall. A thickness (L1) of the heat exchanger outlet-side air duct wall is 0.15L2 to 0.25L2, where L2 represents an inlet width of the air outlet.

摘要： An air conditioner has a casing and a wind direction changing device. The casing has an air inlet, an air outlet, an outer air path wall, and an inner air path wall. The wind direction changing device has an up-down rotation shaft and a deflector. The deflector extends from the up-down rotation shaft toward the outer air path wall. The deflector has an outer air path wall-side end which faces the outer air path wall and has a first arc shape.

摘要： An outdoor unit for a refrigeration cycle apparatus includes an outdoor heat exchanger arranged around an axis on an upstream side of an airflow with respect to a propeller fan. Further, the outdoor heat exchanger includes a first flat surface portion, a second flat surface portion, and a curved portion connecting the first and second flat surface portions to each other. An airflow directing plate is opposed to an end portion of the outdoor heat exchanger on the propeller fan side from the axis side of the propeller fan. The airflow directing plate is opposed to at least any one of the first flat surface portion and the second flat surface portion without being opposed to the curved portion.

摘要： In a blade cross-sectional view, assuming that a tangent at an end of the outer periphery is defined as LQ, an imaginary line orthogonal to the rotation axis is defined as LO, an angle formed by the tangent (LQ) and the imaginary line (LO) is defined as an outer peripheral end tangent angle (θ), and a position at which an imaginary plane including a position of an intake-side end portion of the bellmouth and a peripheral edge of the blade cross each other is defined as an overlap starting point, the outer peripheral end tangent angle on a trailing edge portion side with respect to a blade cross section including the overlap starting point is set to be smaller than the outer peripheral end tangent angle on a leading edge portion side with respect to the blade cross section including the overlap starting point.

摘要： An air blower includes a casing having an air inlet portion and an air outlet portion, a fan, and a fan guard. The fan includes a boss portion and a plurality of blades. The fan guard includes a guide portion having a tubular outer shape, which protrudes toward the fan. A center in a distal end shape, which is defined by a contour line of a distal end portion of the guide portion, matches with a rotation axis of the boss portion. A center in a root shape, which is defined by a contour line of a root portion of the guide portion, is shifted with respect to the rotation axis of the boss portion.
