摘要： A heat exchanger (23) comprises: a first row heat exchange module (50a) into which a refrigerant flows from the outside; a second row heat exchange module (50b) through which the refrigerant flows out to the outside; a third row heat exchange module (50c) through which the refrigerant flows out to the outside; and a split-flow module (40) which splits the refrigerant from the first row heat exchange module (50a) into the second row heat exchange module (50b) and the third row heat exchange module (50c). The first row heat exchange module (50a) forms a refrigerant outward path (50aD), and each of the second row heat exchange module (50b) and the third row heat exchange module (50c) forms a refrigerant return path (50bU, 50cU). This results in a single round trip refrigerant flow path.

摘要： This propeller fan is provided with a hub (11) having a side surface around a center axis (O), and with a plurality of blades (12) provided to the side surface of the hub. Inner peripheral blades extending from the side surface of the hub toward the outer edge side are formed on the respective inner peripheral sections of the plurality of blades at positions on the positive pressure surfaces (12p) of blade surface sections (12c). The inner peripheral blades protrude from the positive pressure surfaces of the blade surface sections toward the positive pressure side (P) and include a plurality of blade elements arranged side-by-side in the rotational direction (R) of the blades. A first blade element (15a) disposed on the front edge side in the rotational direction of the blades among the plurality of blade elements is formed so that, if the vertex of the first blade element protruding from the positive pressure surface is A, the distance from the center axis to the vertex A is r, and a point located at the front edge of the first blade element in the rotational direction at the distance r from the center axis is B, the blade angle (θ) formed between a direction along the blade chord of the first blade element, which extends in the direction connecting the vertex A and the point B, and a plane perpendicular to the center axis is greater than or equal to a predetermined first angle and smaller than or equal to a second angle greater than the first angle.

摘要： This propeller fan is provided with a hub (11) having a side surface (11a) around a center axis (O), and with a plurality of blades provided to the side surface of the hub. Inner peripheral blades extending from the side surface of the hub toward the outer edge side are formed on the respective inner peripheral sections of the plurality of blades at positions on the positive pressure surfaces of blade surface sections. The inner peripheral blades protrude from the positive pressure surfaces of the blade surface sections toward the positive pressure side, and are formed so that the front edge (15a-F) of each inner peripheral blade in a rotational direction (R) is formed curved so as to separate toward the front edge side of the blade in the rotational direction from a reference line (S1) which connects a lower end (E3) located on the positive pressure surface at the base end of the inner peripheral blade connected to the side surface of the hub, and the outer edge (E1) of the inner peripheral blade, which is extended from the side surface toward the outer edge side of the blade and is located on the positive pressure surface. If the length of the reference line is L, and the maximum value of the distance between the reference line and the front edge of the inner peripheral blade is H, then the relationship of H/L ≥ 0.1 is satisfied.

摘要： Un aparato de aire acondicionado 1 incluye un primer control de arranque y un segundo control de arranque como su control de arranque. En el primer control de arranque, los primeros intercambiadores de calor exteriores 24a, 24b se controlan para que funcionen como evaporadores y los segundos intercambiadores de calor exteriores 25a, 25b se controlan para que funcionen como condensadores. Así, incluso cuando los compresores 21a, 21b funcionan con un número de giros dado, se puede evitar que aumenten las presiones de descarga de los mismos, pudiendo así evitar que aumenten las presiones internas de los compresores 21a, 21b. Además, después de finalizar el primer control de arranque, los primeros intercambiadores de calor exteriores 24a, 24b y los segundos intercambiadores de calor exteriores 25a, 25b se controlan para que funcionen como evaporadores, y los compresores 21a, 21b se accionan con un número de rotaciones determinado. Esto puede acortar el tiempo de aumento de la capacidad de calefacción al inicio de la operación de calefacción normal. (Traducción automática con Google Translate, sin valor legal)

摘要： This heat exchanger is equipped with a plurality of flat heat transfer tubes (11), and a header (12) joined to end portions of the plurality of flat heat transfer tubes (11), wherein a plurality of upwind flow passages (44) and a plurality of downwind flow passages (45) arranged downwind from the plurality of upwind flow passages (44) are formed in the interior of each of the plurality of flat heat transfer tubes (11). The header (12) has: a main body section (20), in which is formed an interior space connected to the plurality of upwind flow passages (44) and the plurality of downwind flow passages (45); a partition member (22), which partitions the interior space into an upwind space (24) on the side closer to the ends of the plurality of upwind flow passages (44) and a downwind space (25) on the side closer to the ends of the plurality of downwind passages (45); and an outflow/inflow part (27), through which a refrigerant is supplied to the lower portion of the upwind space (24) and through which the refrigerant is discharged from the lower portion of the upwind space (24). A lower communication passage (29) enabling communication between the downwind space (25) and the upwind space (24) is formed at the lower portion of the partition member (22).
