The specific implementation scheme of the partition combined air supply with different air supply modes is as follows:

the specific implementation scheme under the refrigeration working condition is as follows:

as shown in fig. 4, when the air conditioner is turned on for cooling, an infrared detector or a temperature sensor is used to detect the indoor temperature tin and the outdoor temperature tout of the current room. The current set temperature of the air conditioner is tc, and Δ tin is defined as the difference between the current indoor temperature tin and the set temperature tc of the air conditioner, and Δ tout is the difference between the current outdoor temperature tout and the indoor temperature tin.

Firstly, judging the relation between the current indoor temperature and the set temperature of the air conditioner:

(1) if the difference between the current set temperature tc of the room air conditioner and the indoor temperature tin is less than or equal to t1, the relationship between the current indoor temperature and the outdoor temperature of the room is further determined,

1) if the difference between the current room outdoor temperature tout and the indoor temperature tin is less than or equal to t3, the difference between the set temperature of the air conditioner and the indoor temperature is relatively small, but the comfortable indoor temperature of a human body is not reached, the refrigeration mode still needs to be started, at the moment, the upper fan 27 volute 23 faces upwards (downwards), the lower fan 27 volute 23 faces downwards (upwards), the upper baffle and the lower baffle of the left (right) air supply cylinder are opened, the middle baffle is closed, the discomfort caused by directly blowing cold air to the human body is avoided, and the air can be supplied to the left and right partitions at the same time in a single-side and vertical mode.

2) If the difference value between the current outdoor temperature tout and the indoor temperature tin of the room is larger than t3, the fact that the air conditioner is in the later stage of refrigerating operation indicates that the indoor temperature relatively reaches a stable state, at the moment, only the upper and lower fans 27 are controlled to face upwards, the upper baffle plates of the left and right air supply cylinders are opened, the middle baffle plates and the lower baffle plates are closed, single or simultaneous upward air supply of left and right partitions can be achieved, and discomfort caused by cold air accumulation on the ground in the stable stage of the air conditioner is avoided.

1) if the difference value between the current room outdoor temperature tout and the current room indoor temperature tin is less than or equal to t2, the air conditioner is in a cooling operation stage just started, the indoor temperature is high, the air conditioner needs to be cooled quickly, and the upper baffle, the middle baffle and the lower baffle of the left (right) air supply cylinder are opened by controlling the upward (downward) volute 23 of the upper fan 27 and the downward (upward) volute 23 of the lower fan 27, so that the cold air is simultaneously supplied to the left (right) partition on one side from the upper part to the middle part.

2) If the difference between the current outdoor temperature tout of the room and the indoor temperature tin is greater than t2, the result shows that the air conditioner has been operated for a period of time, the indoor temperature has been gradually reduced, but the stable state has not been reached yet, the upward (downward) volute 23 of the upper fan 27 and the downward (upward) volute 23 of the lower fan 27 need to be controlled, the upper baffle and the middle baffle of the left (right) air supply cylinder are opened, the lower baffle is closed, the vertical temperature difference of air is large due to cold air accumulation on the ground, the simultaneous air supply on the single side of the left (right) partition can be realized, and the requirements of different living areas of a user are met.

1) if the difference between the current outdoor temperature tout and the indoor temperature tin of the room is smaller than or equal to t3, the difference between the set temperature of the air conditioner and the indoor temperature is relatively small, the indoor heat supply is small, but the heating mode still needs to be started, at the moment, the volute 23 of the upper fan 27 and the lower fan 27 is controlled to face downwards, the baffle in the left (right) air supply cylinder is opened, the upper baffle and the lower baffle are closed, air supply in a single mode or in a simultaneous mode in a left-right partition mode can be achieved, the requirement of hot air warming people is met, and the phenomenon that hot air is attached to the ground is avoided.

2) If the difference value between the current outdoor temperature tout and the indoor temperature tin of the room is larger than t3, the air conditioner is indicated to be in the later stage of heating operation, the air conditioner heats to reach a temperature point, at the moment, only the upper fan 27 and the lower fan 27 are controlled to face downwards, the lower baffle plates of the left air supply cylinder and the right air supply cylinder are opened, the upper baffle plate and the middle baffle plate are closed, single or simultaneous lower air supply of left and right partitions can be realized, and the problem of head and foot cooling caused by long-time operation of the air conditioner is avoided.

(2) If the difference between the current set temperature tc of the room air conditioner and the indoor temperature tin is greater than t1, the relationship between the current indoor temperature of the room and the outdoor temperature is further judged,

1) if the difference between the current outdoor temperature tout and the indoor temperature tin of the room is less than or equal to t2, the air conditioner is in a stage of just starting heating operation, the indoor temperature is relatively low, the air conditioner is required to realize rapid heating, and the upper baffle, the middle baffle and the lower baffle of the left (right) air supply cylinder are opened by controlling the upward (downward) volute 23 of the upper fan 27 and the downward (upward) volute 23 of the lower fan 27, so that the single-side upper-middle-lower simultaneous hot air supply of the left (right) partition is realized.

2) If the difference between the current outdoor temperature tout and the indoor temperature tin of the room is greater than t2, it indicates that the air conditioner has been heated and operated for a period of time, but the temperature point has not yet been reached, the volute 23 of the upper and lower fans 27 needs to be controlled to face down, the middle and lower baffles of the left (right) air supply cylinder are opened, the upper baffle is closed, hot air is prevented from attaching to the ceiling, and single-side middle-lower or simultaneous middle-lower air supply of the left and right partitions can be realized.
