Each wall-mounted unit meets the demand for accurately controlling the refrigerant flow rate flowing through the wall-mounted unit by controlling its throttling component 300. It is suitable for installation after the indoor ceiling is completed (such as after the indoor decoration is completed).

[0023] In some examples, such as Figures 1 to 3 As shown, the throttling component 300 is vertically arranged along the width direction of the chassis 100, so that the throttling component 300 occupies less space in the length direction of the chassis 100 and has less impact on the length dimension of the heat exchanger 200.

[0024] In some embodiments, Figure 2 As shown, the throttling component 300 is an electronic expansion valve, which includes a first connecting pipe 310, a valve body 320 and a second connecting pipe 330 that are connected in sequence. The first connecting pipe 310 and the second connecting pipe 330 are located on the same side of the valve body 320 in the width direction of the chassis 100 and are both vertically arranged along the width direction of the chassis 100. One of the first connecting pipe 310 and the second connecting pipe 330 is connected to the first port of the heat exchanger 200, and the other is arranged to be connected to the first interface of the air conditioner outdoor unit.

[0026] In some examples, such as Figures 1 to 3 As shown, the wall-mounted unit also includes: a first refrigerant pipe 410, one of the first connecting pipe 310 and the second connecting pipe 330 is connected to the first port of the heat exchanger 200 through the first refrigerant pipe 410; and a second refrigerant pipe 420, one end of the second refrigerant pipe 420 is connected to the second port of the heat exchanger 200, and the other end of the second refrigerant pipe 420 is configured to be connected to the second interface of the air conditioner outdoor unit.

[0027] In one embodiment, if Figures 1 to 3 As shown, one of the first refrigerant pipe 410 and the second refrigerant pipe 420 is configured as a collecting pipe, and the other is configured as a shunt pipe, so that the heat exchange efficiency of the heat exchanger 200 is higher and the heat exchange effect is better.

[0028] In some examples, such as Figures 1 to 3 As shown, the wall-mounted machine also includes: a fan assembly, which is arranged in the first installation area 110 and the second installation area 120, the heat exchanger 200 is located on the side of the fan assembly facing away from the chassis 100, and the throttling component 300 is located on one side of the fan assembly in the width direction of the chassis 100.

[0029] The chassis 100 is installed on the indoor wall, the width direction of the chassis 100 is the up and down direction, and the throttling component 300 is located at the lower side of the fan assembly, making full use of the space of the second installation area 120 located at the lower side of the fan assembly.
