An air conditioner indoor unit has a first refrigerant tubing (5, 7) of which one end part is connected to an indoor heat exchanger (2) and that is formed of aluminum or an aluminum alloy, a second refrigerant tubing (6, 8) of which one end part is connected to the other end part of the first refrigerant tubing (5, 7) and that is formed of copper or a copper alloy, and a flare union (9, 10) connected to the other end part of the second refrigerant tubing (6, 8). The connection between the other end part of the first refrigerant tubing (5, 7) and the one end part of the second refrigerant tubing (6, 8) is between an end at the flare union (9, 10) side of a bend section (5b, 7b) of the first refrigerant tubing (5, 7) and the end at the flare union (9, 10) side of the second refrigerant tubing (6, 8). As a result, it is possible to prevent the occurrence of large torsional stress and bending stress at the connection. |
