When the indoor space is larger and the air supply distance is longer, the air outlet of the first air supply barrel 301 and the air outlet of the second air supply barrel 302 are both biased to the first air outlet 103 only by the first air outlet 103 or the air outlet 303 of the air supply barrel, so that a polymerization remote direct blowing mode is formed. The long-distance air supply effect can be realized. For example, the air conditioner is placed in a living room, and when a user eats in a restaurant, the air can be exhausted by adopting the mode.

When the user does not need to blow directly, the air outlet of the first air barrel 301 and the air outlet of the second air barrel 302 can be controlled to deviate from the positions of the user, and the air flow flowing out of the first air outlet 103 can be consistent with the air outlet direction of the first air barrel 301 and the second air barrel 302 under the guidance of the air flow flowing out of the air outlet of the first air barrel 301 and the air outlet of the second air barrel 302 due to the fact that the first air outlet 103 is positioned between the first air barrel 301 and the second air barrel 302. In this embodiment, the wind direction of the middle air duct may be adjusted by a vector adjustment technique.

When the user needs to quickly adjust the indoor temperature, the air outlets of the first air supplying barrel 301 and the second air supplying barrel 302 deviate from the first air outlet 103, so that the air outlet range of the air conditioner is increased, large-scale air supply can be realized, and the purpose of quickly adjusting the indoor temperature is achieved.

When indoor personnel are scattered, the first air barrel 301 and the second air barrel 302 are rotated to the maximum wide-angle air outlet position, and the first air outlet 103 is used for leading air to flow out, so that wall-attached surrounding air supply can be formed. The surrounding air supply is realized without blowing people, so that indoor people can feel the air outlet of the air conditioner.

When indoor people have users who do not like air conditioning and direct blowing, and users who do not like direct blowing, the air output of the first air barrel 301 and the air output of the second air barrel 302 can be controlled to be different, the air output of the air barrel 30 facing the people who like direct blowing can be in a large air volume mode, and the air output of the air barrel 30 facing the people who do not like direct blowing can be in a small air volume mode. Meanwhile, the first air outlet 103 can normally outlet air, so that the temperature can be quickly adjusted while the requirements of various people are met.

When the indoor temperature is generally high or generally low, the air conditioner is not required to operate at a high rotating speed and a large air volume at the beginning, and the first fan 101 and the second fan 201 can be selected to operate at a low rotating speed, or only one of the first heat exchanger or the second heat exchanger 202 is opened, so that the first fan 101 and the second fan 201 normally operate. The energy consumption of the air conditioner is reduced while the temperature is guaranteed to be regulated.

In this embodiment, the third air duct 405 can guide the ambient air to flow to the first air outlet 103 and/or the air outlet 303 of the air duct, and mix with the air flow flowing out from the first air outlet 103 and/or the air outlet 303 of the air duct to form a uniform air, so that the uniform air is softer, the temperature is more suitable, and the comfort level of indoor users is increased. Particularly, when the air conditioner is used for refrigerating, the air is cooled uniformly and is not cooled, so that the cold air can be prevented from blowing to a user, and the user is prevented from suffering from air conditioning diseases.

Meanwhile, the air flows flowing out from the air outlet of the first air barrel 301, the air outlet of the second air barrel 302 and the air outlet of the first air barrel 103 enable the third air outlet 407 to form negative pressure, and the ambient air flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure of the third air outlet 407, and flows out after being mixed with the air of the second air duct 20 and the first air duct 10, so that the uniform air outlet of the air conditioner is realized, and the air outlet can be ensured.

When indoor people do not like air conditioning and blow directly, but need the rapid adjustment of the ambient temperature in place, the air output of the first air supply barrel 301 and the second air supply barrel 302 can be controlled to be the same, meanwhile, the first air supply barrel 301 and the second air supply barrel 302 are adjusted to be turned to be not towards the user, and the air output of the first air outlet 103 can be not towards the user under the action of vector direction adjustment. Meanwhile, the air flows out of the air outlet of the first air barrel 301, the air outlet of the second air barrel 302 and the air outlet of the first air barrel 103 enable the third air outlet 407 to form negative pressure, and the ambient air flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure of the third air outlet 407, and flows out after being mixed with the air of the second air duct 20 and the first air duct 10. Finally, the air is evenly discharged, the people are avoided, the air quantity is large, and the people are not blown directly.

When the indoor space is larger and the air supply distance is longer, the air outlet of the first air supply barrel 301 and the air outlet of the second air supply barrel 302 are both biased to the first air outlet 103 only by the first air outlet 103 or the air outlet 303 of the air supply barrel, so that a polymerization remote direct blowing mode is formed.

And the air flows out from the air outlet of the first air barrel 301, the air outlet of the second air barrel 302 and the air outlet of the first air barrel 103 form negative pressure at the third air outlet 407, and the environmental air flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure of the third air outlet 407, and flows out after being mixed with the air of the second air duct 20 and the first air duct 10. The temperature is guaranteed to be regulated, meanwhile, air is evenly distributed and discharged, and the energy consumption of the air conditioner is reduced.

In this embodiment, the first air duct 10 and the second air duct 20 can flow out heat exchange air or ambient air by controlling the opening and closing of the corresponding heat exchangers, wherein one of the first air duct 10 and the second air duct 20 is driven by a fan to flow out ambient air, and the mixed air flowing out after the ambient air is mixed with the other one of the first air duct 10 and the second air duct 20 flowing out of the heat exchange air can be referred to as active air balancing. In the case that the air outlet 303 of the first air outlet 103 or the air outlet 303 of the air duct forms a negative pressure, the mixed air flowing out of the third air duct 405 after the ambient air flowing out of the third air outlet 407 is mixed with the heat exchange air flowing out of the air outlet 103 of the air duct or the air outlet 303 of the air duct may be referred to as passive air balancing.
