摘要： A heat exchanger includes a plurality of plate-shaped fins disposed at intervals, and a plurality of heat transfer tubes disposed to be inserted into through holes of the fins in a direction perpendicular to the fins. In each of the fins, a starting hole is formed between adjacent through holes, and the starting hole serves as a start point of bending of the fins and has a vertex portion at a bending portion of each fin which is close to an edge thereof. In each of the fins, a cut is made to connect the other edge of the fin and a side of the starting hole which is located opposite to the vertex portion of the starting hole. The above each fin is bent at the vertex portion of the starting hole, by opening the cut from the starting hole.

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

摘要： An air conditioner (10) includes a compressor (1), a condenser (2), an expansion valve (3), an evaporator (4), and a temperature detection unit (7). The compressor (1) is configured to compress refrigerant. The condenser (2) is configured to condense the refrigerant compressed by the compressor (1). The expansion valve (3) is configured to decompress the refrigerant condensed by the condenser (2). The evaporator (4) is configured to evaporate the refrigerant decompressed by the expansion valve (3). The temperature detection unit (7) is attached to the condenser (2) and is configured to detect a temperature of the refrigerant in the condenser (2). The expansion valve (3) is configured to be capable of adjusting a flow rate per unit time of the refrigerant flowing through the expansion valve (3) by adjusting a degree of opening of the expansion valve (3). The degree of opening of the expansion valve (3) is increased when the temperature of the refrigerant detected by the temperature detection unit (7) rises, and the degree of opening of the expansion valve (3) is decreased when the temperature of the refrigerant detected by the temperature detection unit (7) falls.

摘要： A propeller fan of the present invention includes: a rotation-axis part that serves as a center of rotation; and a plurality of blades provided on an outer circumferential side of the rotation-axis part, the plurality of blades being joined to adjoining blades at leading edges and trailing edges thereof. A first rib projecting in a direction of the center of rotation of the rotation-axis part to surround the rotation-axis part, and second ribs projecting in the direction of the center of rotation to extend from the rotation-axis part toward the first rib are provided on pressure surfaces of the plurality of blades. Among ends of the second ribs in the direction of the center of rotation, the ends distant from the pressure surfaces project in a direction away from the pressure surfaces farther than an end of the first rib distant from the pressure surfaces, among the ends of the first rib in the direction of the center of rotation.
