摘要： Disclosed herein is a blower blowing air and an outdoor unit of air conditioner having the same. The blower includes a fan, a motor driving the fan, and a motor support member disposed on a flow path, through which air generated by a rotation of the fan flows, to support the motor. The motor support member includes a cross-sectional shape including a maximum width portion having a maximum width in a direction perpendicular to the airflow direction, an upstream portion having a width being increased from the upstream side to the downstream side, and a downstream portion having a width being reduced from the upstream side to the downstream side. A downstream end located downstream of the downstream portion has a width in a direction perpendicular to the airflow direction.

摘要： An outdoor unit for a refrigeration cycle apparatus includes: a fan; a bellmouth that covers a periphery of the fan; a casing that internally houses the fan and the bellmouth so that airflow faces upward and that has a top end edge having a flat shape; and a diffuser surface disposed below a top end edge of the casing but above a top end of the bellmouth and on the outer side relative to the top end of the bellmouth in plan view, wherein the diffuser surface is inclined to extend outward away from the rotation axis of the fan as getting upward. The casing has a plurality of side surfaces that cover the sides of the bellmouth. At least one of the side surfaces has a recessed shape toward the bellmouth so that a gap with the top end edge of the bellmouth is reduced.

摘要： A split air conditioner has a cabinet with a fan and evaporator for mounting within a structure. The cabinet includes a filter or a stacked filter system positioned in the flow path between an air inlet and an air outlet for filtering contaminants from the air. Movable dampers are provided for selectively changing the airflow path to selectively bypass the filter to provide a greater or lesser degree of filtration of the air. Preferably, the filter is a high performance HEPA-like filter having substantially less pressure drop.
