  • Patent number: 11168948
    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.

  • Patent number: 10655900
    Abstract: Provided is an air-conditioning apparatus configured so that a decrease in a refrigeration capacity can be suppressed without increasing the amount of refrigerant with which a refrigerant circuit is filled and that refrigerant can be suitably stored during a pump down operation. The air-conditioning apparatus includes a first on-off valve provided at a pipe between an expansion valve and a use side heat exchanger, a bypass branching from a pipe between the expansion valve and the first on-off valve and connected to a pipe at a suction-side of a compressor, and a refrigerant storage unit configured to store the refrigerant having passed through the bypass. In a pump down operation in which the compressor operates with the first on-off valve being in a closed state, the refrigerant having flowed out from the heat source side heat exchanger flows into the bypass, and then, is stored in the refrigerant storage unit.

  • Patent number: 10274219
    Abstract: When a controller determines that a leakage of refrigerant occurs, the controller executes a control of rotating an air-sending fan at high rotation speed. After the control, the controller executes a control of stopping rotation of the air-sending fan or reducing a rotation speed of the air-sending fan in accordance with a result of detection by a first refrigerant sensor provided in a lower portion of a heat exchanger chamber. Thus, the air-sending fan is prevented from continuing the rotation at high rotation speed. Therefore, an indoor unit for an air-conditioning apparatus is excellent in safety and is capable of avoiding feeling of discomfort of a user due to the high-speed rotation of the air-sending fan.
