Alternatively, the rotation angle of each barrel 30 ranges from 0 ° to 180 °. When the rotation angle of the air supply barrel 30 is 0 degree, the air supply barrel 30 is located at the shutdown position; when the air supply barrel 30 rotates to 180 degrees, the air supply barrel 30 is located at the maximum wide-angle air outlet position.

Taking the first air outlet 103 for blowing air forward, the first air supply barrel 301 and the second air supply barrel 302 are divided into two parts located at the two sides of the first air outlet 103, and various air-out modes of the air conditioner are described as follows:

when the second fan 201 is in a shutdown state and no airflow flows in the second air duct 20, the first air supply barrel 301 and the second air supply barrel 302 are both located at a shutdown position.

When the indoor temperature is very high and the user expects the air conditioner to blow directly, the controller controls the first heat exchanger and the second heat exchanger 202 to be communicated, controls the first fan 101 and the second fan 201 to rotate at high grade, controls the air output of the two second air outlets 303 at the first air supply barrel 301 and the second air supply barrel 302 to be the same, and controls the first air outlet 103 and the second air outlet 303 to be forward, so that the air outlet of the air conditioner is forward. The large-air-volume direct blowing device of the air supply cylinder 30 can realize direct blowing of people, and can quickly adjust the temperature of the indoor environment.

When the indoor space is large and the air supply distance is long, and the air cannot be supplied to a target position only by the first air outlet 103 or the second air outlet 303, the controller controls the first heat exchanger and the second heat exchanger 202 to be communicated, controls the first fan 101 and the second fan 201 to rotate at high grade, and controls the second air outlet 303 of the first air supply barrel 301 and the second air outlet 303 of the second air supply barrel 302 to deviate from the first air outlet 103, so that a polymerization long-distance direct blowing mode is formed. The remote air supply effect can be realized. For example, the air conditioner is arranged in a living room, and when a user has a meal in the dining room, the air can be exhausted by adopting the mode.

When a user does not need to blow directly but needs to adjust the ambient temperature quickly to a proper position, the controller can control the first heat exchanger and the second heat exchanger 202 to be communicated, control the first fan 101 and the second fan 201 to rotate at high-grade, control the air output of the two second air outlets 303 at the first air supplying barrel 301 and the second air supplying barrel 302 to be the same, control the second air outlet 303 of the first air supplying barrel 301 and the second air outlet 303 of the second air supplying barrel 302 to deviate from the position of the user, and control the air flow flowing out of the first air outlet 103 to be consistent with the air output direction of the two second air outlets 303 at the first air supplying barrel 301 and the second air supplying barrel 302 under the guidance of the air flow flowing out of the two second air outlets 303 at the first air supplying barrel 301 and the second air supplying barrel 302 because the first air outlet 103 is located between the first air supplying barrel 301 and the second air supplying barrel 302. In this embodiment, the wind direction of the first wind outlet 103 can be adjusted by the vector adjustment technique.

When a user needs to quickly adjust the indoor temperature, the second air outlet 303 of the first air supplying barrel 301 and the second air outlet 303 of the second air supplying barrel 302 are deviated from the first air outlet 103, so that the air outlet range of the air conditioner is increased, air can be supplied in a large range, and the purpose of quickly adjusting the indoor temperature is achieved. Or, the controller can control the rotation speed of the first air supply barrel 301 and the second air supply barrel 302 to be increased, so that the air sweeping frequency of the second air outlet 303 is increased, the air flow is increased, and the temperature can be quickly adjusted.

When indoor personnel are scattered, the first air supply barrel 301 and the second air supply barrel 302 both rotate to the maximum wide-angle air outlet position, the first air outlet 103 exhausts air forwards, and wall-attached surrounding type air supply can be formed. The air supply is surrounded and people are not blown, so that indoor personnel can feel the air outlet of the air conditioner.

When indoor personnel have users who dislike direct blowing of the air conditioner and people who like to enjoy direct blowing, the controller controls the first heat exchanger and the second heat exchanger 202 to be communicated, controls the air outlet quantities of the first air supply barrel 301 and the second air supply barrel 302 to be different, the air supply barrel 30 facing the people who like to directly blow can be in a large air quantity mode, and the air supply barrel 30 facing the people who dislike to directly blow can be in a small air quantity mode. First air outlet 103 normally goes out the air simultaneously, when satisfying multiple personnel's demand, can also guarantee the quick adjustment temperature.

When the indoor temperature is generally high or generally low, the air conditioner does not need to operate at a high rotating speed and a large air volume at the beginning, the first fan 101 and the second fan 201 can be selected to operate at a low rotating speed, or only one first heat exchanger or only one second heat exchanger 202 is opened, and the first fan 101 and the second fan 201 operate normally. The energy consumption of the air conditioner is reduced while the temperature is regulated. Or, the driving device 50 is controlled to enable the air duct to maintain low-speed rotation, so that the temperature can be maintained, and energy can be saved.

When the user information is the user state, the user state may be a user sleep state. When the user does not fall asleep, the first heat exchanger and the second heat exchanger 202 are controlled to be communicated, the first fan 101 and the second fan 201 are controlled to rotate at a medium gear or a high gear, and the indoor temperature is adjusted.
