Abstract: 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.

Abstract: An air conditioner includes a refrigerant circuit and refrigerant. The refrigerant circuit has a compressor, a condenser, a pressure-regulating valve, and an evaporator. The refrigerant is R32. The pressure-regulating valve includes a flow path causing the refrigerant flowing from the condenser to flow to the evaporator, a pressure reference chamber partitioned from the flow path and filled with inert gas, and a valve portion. The pressure-regulating valve is configured to adjust a degree of opening of the valve portion to adjust a flow rate of the refrigerant flowing through the flow path. The valve portion is configured to increase the degree of opening when a pressure in the flow path is higher than a pressure in the pressure reference chamber, and reduce the degree of opening when the pressure in the flow path is lower than the pressure in the pressure reference chamber.

Abstract: A propeller fan 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 towards the center of rotation of the rotation-axis part to surround the rotation-axis part, and second ribs projecting towards 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 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.

Abstract: An indoor unit of an air-conditioning apparatus eliminates a possibility of condensation on a front panel without deteriorating a quality of design. In an off state, an auxiliary air-directing plate is positioned above an up-down air-directing plate inside an air outlet such that a free end of the auxiliary air-directing plate opposite from one end of the auxiliary air-directing plate fixed to a rotating shaft is positioned closer to a rear surface of a casing than is the rotating shaft. In an on state, the auxiliary air-directing plate is rotated in a direction from the rear surface to a front surface of the casing, and the free end is protruded from the air outlet to an outside of the casing.

Abstract: In an air-conditioning, first flow passage selection device and a second flow passage selection device each are a constant-energized-type three-way valve in which a position of a main valve can be fixed in a de-energized state. When the refrigerant circuit is switched to the cooling circuit by a flow switching device, when at least one of the first flow passage selection device and the second flow passage selection device is in a de-energized state, the first flow passage selection device or the second flow passage selection device in the de-energized state is configured to output refrigerant discharged from the compressor and input therein via the flow switching device and the bypass pipe to a corresponding one of an upper-side outdoor heat exchanger and a lower-side outdoor heat exchanger.

Abstract: An indoor unit for an air-conditioning apparatus includes a casing, an up-down airflow direction plate rotatably supported in the air outlet, and an auxiliary airflow direction plate rotatably supported below, and on an upstream side of, the up-down airflow direction plate. The up-down airflow direction plate has a main blade part formed of a flat plate and a rear edge part formed of a flat plate. When the main blade part is in a horizontal state, the rear edge part is inclined upward to a back face of the casing from the main blade part. When an angle α formed between the main blade part and the rear edge part and an angle ε formed between the main blade part and a virtual line through a center of a tip part of the auxiliary airflow direction plate, ε is greater than α.
