PROBLEM TO BE SOLVED: To provide an air-conditioner indoor unit that is a wall-mounted air-conditioner indoor unit, that can make inlet/outlet pipes less damaged even if a force is applied to the inlet/outlet pipes connected to a communication pipe between the air-conditioner indoor unit and an air-conditioner outdoor unit, and that can make simpler work such as installation work.SOLUTION: An air-conditioner indoor unit 10 is a wall-mounted air-conditioner indoor unit connected to an air-conditioner outdoor unit via a communication pipe. The air-conditioner indoor unit comprises an indoor heat exchanger 20 and a liquid-refrigerant indoor-refrigerant pipe assembly 60. The liquid-refrigerant indoor-refrigerant pipe assembly 60 includes a liquid-refrigerant large-diameter pipe 61 and a liquid-refrigerant small-diameter pipe 65. The liquid-refrigerant large-diameter pipe 61 is connected to the communication pipe. The liquid-refrigerant small-diameter pipe 65 is connected to the indoor heat exchanger 20 and communicates the indoor heat exchanger 20 with the liquid-refrigerant large-diameter pipe 61. The liquid-refrigerant large-diameter pipe 61 includes a trap 66 formed therein, the trap 66 including a first curved portion 66a curved into U-shape on a first flat surface; and a second curved portion 66b curved into a U-shape on a second flat surface crossing the first flat surface. |
