摘要： In a heat exchanger, a first heat exchange unit is formed by curving a third heat exchange unit having a planar shape through L-shape bending, and a second heat exchange unit is formed by curving a fourth heat exchange unit having a planar shape through the L-shape bending, independently of the third heat exchange unit. The first heat exchange unit and the second heat exchange unit are arranged so as to be opposed to each other along a corner portion between adjacent two side surfaces of a casing.

摘要： A propeller fan according to an embodiment of the present invention includes a shaft provided a rotation axis of the propeller fan, and a blade provided on an outer peripheral side of the shaft. The blade has a trailing edge on a rear side of the blade in a rotation direction of the propeller fan. The trailing edge includes a first trailing edge located on an innermost side of the trailing edge, and a second trailing edge adjacent to and outward of the first trailing edge. Where an innermost point of the first trailing edge is a first connection point, a connection point between the first trailing edge and the second trailing edge is a second connection point, and a straight line that extends through the rotation axis and the first connection point is a reference line, the second connection point is located forward of the reference line in the rotation direction, or located on the reference line, and the second trailing edge is located rearward of the second connection point in the rotation direction.

摘要： A heat exchanger, in which refrigerant causing disproportionation is used, includes a main heat exchange unit including a plurality of first heat transfer pipes arranged side by side, a sub-heat exchange unit including a plurality of second heat transfer pipes arranged side by side, and a relay unit including a plurality of relay passages connecting the plurality of first heat transfer pipes and the plurality of second heat transfer pipes. Each of the plurality of relay passages has one inlet connected to a corresponding one of the plurality of second heat transfer pipes, and a plurality of outlets each connected to a corresponding one of the plurality of first heat transfer pipes. Each of the plurality of relay passages distributes the refrigerant flowing from the one inlet, without merging streams of the refrigerant together, and causes the refrigerant to flow out of the plurality of outlets.
