When the airflow passes through the first heat exchanger 24, the airflow exchanges heat with the first heat exchanger 24, and heat or cold on the first heat exchanger 24 is transmitted to the airflow to heat or cool the airflow, so that hot air or cold air is finally output from the air outlet 23.

In one exemplary embodiment, as shown in fig. 6, the support 16 is provided with a second mounting groove 163. The second mounting groove 163 is formed by the support 16 being inwardly depressed toward the side of the first panel 20. The first heat exchanger 24 is embedded in the second mounting groove 163. The first heat exchanger 24 is fixed to the support 16.

Embedding the first heat exchanger 24 up to the second installation groove 163 can save space while also facilitating installation of the first heat exchanger 24.

In an exemplary embodiment, as shown in FIG. 9, the fan assembly 1 further includes a mount 17. The mount 17 is disposed in the second mount groove 163. The mounting seat 17 may have a bar shape. One end of the mounting seat 17 is connected to the side plate of the first heat exchanger 24, and the other end of the mounting seat 17 extends to a position near the first air inlet hole 122. The second body 151 of the switching motor 15 is installed on one end of the mounting seat 17 adjacent to the first air inlet hole 122. This arrangement fixes the second body 151 of the switching motor 15.

In one exemplary embodiment, as shown in fig. 8, the air conditioner 100 further includes a second heat exchanger 25, a fan 27, and a compressor 26. The second heat exchanger 25 and the compressor 26 are both disposed in the case 2 and are both fixed to the chassis 21 of the case 2. The second heat exchanger 25 and the fan 27 are disposed at the outdoor side of the cabinet 2. The second heat exchanger 25 is used for heat exchange with outdoor air, and the fan 27 is used for fanning the second heat exchanger 25 to accelerate the heat exchange between the second heat exchanger 25 and the outdoor air. The first heat exchanger 24, the second heat exchanger 25 and the compressor 26 are connected to form a loop through pipes, and the loop is filled with a refrigerant. The compressor 26 can drive the refrigerant to flow in the circuit, so that the first heat exchanger 24 and the second heat exchanger 25 exchange heat.

When the air conditioner 100 performs cooling, heat in indoor air is conducted to the first heat exchanger 24, the refrigerant brings heat on the first heat exchanger 24 to the second heat exchanger 25, and heat on the second heat exchanger 25 is dissipated to outdoor air; when the air conditioner 100 performs cooling, heat in outdoor air is transferred to the second heat exchanger 25, the refrigerant brings heat in the second heat exchanger 25 to the first heat exchanger 24, and the heat in the first heat exchanger 24 is dissipated into indoor air.
