When the air conditioner is working, if the air conditioner is in a heating state, the first fan 4 and the second fan 5 can be controlled to send down the air at the same time. The second fan 5 can increase the air intake of the air conditioner and increase the air conditioner. The air inlet speed of the first fan 4 increases the air supply distance of the first fan 4, thereby realizing the carpet air supply and improving the heating comfort. When the air conditioner is in a cooling state, the first fan 4 and the first fan 4 can be operated at the same time. The second fan 5 realizes rapid cooling in the room. After the room temperature cools down, the first fan 4 is turned off, and the heat exchanger is normally cooled. Then the second fan 5 changes the airflow direction, so that the airflow flows from the second air inlet and outlet 3 Perform the top airflow so that the air in the room enters through the first air inlet and outlet 2 and is heat-exchanged and cooled by the heat exchanger, and then discharged from the top, so that the cold air is blown up, and then the shower-type airflow is achieved, so that the cold air cannot be completely blown to people. Achieve windless feeling and improve cooling comfort. With the above-mentioned structure, not only the rapid cooling and heating adjustment can be achieved, but also a real windless feeling can be achieved, and the cooling and heating effect is not attenuated, which effectively improves the air-supply comfort.

In this embodiment, both the first and second air inlets and

outlets

3 and 3 can be used as both an air inlet and an air outlet, so that the air outlet direction can be adjusted according to different working conditions, and heating can be performed. Under the state, it can realize the down wind, which can superimpose the wind, enhance the supply wind, and in the cooling state, realize the up wind, can cool the air upward, and improve the comfort of the air supply.

It can provide an accurate air supply direction, so that the air supply direction can be adjusted. Control, so that when superimposing the air volume, the efficiency of the superimposing air volume is improved, the air utilization rate is improved, and the air output effect is improved.

In some embodiments, the first fan 4 is a cross-flow fan. Cross-flow blades can provide a large air supply distance. When combined with an axial flow fan, they can combine the advantages of both to weaken the shortcomings of both. On the basis of ensuring sufficient air volume, provide a sufficient air supply distance, so that The indoor temperature regulation is more efficient and the temperature distribution is more uniform.

A heat exchanger 6 is also provided in the casing 1, and the heat exchanger 6 is located between the first fan 4 and the second fan 5. When the air conditioner is running, whether it is up or down, it can realize sufficient heat exchange with the heat exchanger 6 and improve heat exchange efficiency.
