DETAILED DESCRIPTION

[0026] See also Figure 1 to Figure 2 As shown, according to an embodiment of the present application, an air conditioning system includes an air conditioning unit and an air flow guide pipe, the air inlet end of the air flow guide pipe is connected to the exhaust end of the air conditioning unit, and the air flow guide pipe is provided with at least a first air outlet and a second air outlet, and the second air outlet is located above the first air outlet;

[0027] The air conditioning system further includes a first detection unit 41 and a second detection unit 42, wherein the first detection unit 41 is used to monitor the indoor environment temperature, and the second detection unit 42 is used to monitor the flow information of personnel;

[0028] When the first detection unit 41 detects that the indoor ambient temperature is lower than the first temperature threshold, and the second detection unit 42 detects the movement of people, the air conditioning unit enters the heating mode, and the warm air is discharged from the first air outlet;

[0029] When the first detection unit 41 detects that the indoor ambient temperature is higher than the second temperature threshold, and the second detection unit 42 detects the movement of people, the air conditioning unit enters the cooling mode, and cold air is discharged from the second air outlet.

[0030] By providing the first air outlet and the second air outlet, when the air conditioner is cooling, cold air is discharged from the second air outlet located at a higher position, and the cold air descends, which can use less energy to quickly reduce the indoor temperature and achieve the purpose of cooling. When the air conditioner is heating, cold air is discharged from the first air outlet located at a lower position, and the hot air rises, which can use less energy to quickly increase the indoor temperature and achieve the purpose of heating.

[0031] Furthermore, by setting the first detection unit 41 and the second detection unit 42, the indoor temperature is monitored by the first detection unit 41. The flow of indoor personnel is monitored by the second detection unit 42, and when the indoor temperature is higher than the first temperature threshold or lower than the second temperature threshold, and when the flow of personnel is detected, the air conditioning system is started. Only when the indoor temperature is higher than the first temperature threshold or lower than the second temperature threshold, and there is no flow of personnel, the air conditioning unit does not work. When there is only flow of personnel and the indoor temperature is between the first temperature threshold and the second temperature threshold, the air conditioning unit does not work. It can avoid the air conditioner from still running in idle time or space, resulting in a waste of resources and energy consumption, and provide a comfortable environment for indoor personnel by ensuring that the air conditioning equipment is turned on in time when the room temperature exceeds a predetermined range.

[0032] Furthermore, the first detection unit 41 is a temperature detection device. The second detection unit 42 is a passenger flow counter for counting the flow of people.

[0033] The first air outlet is set at the indoor bottom of the building, and the second air outlet is set at the indoor top of the personnel activity area. In a large and tall building, people are concentrated in the activity area, not in the high-rise area, so it is not meaningful to raise or lower the temperature in the high-rise area. Setting the second air outlet at the indoor top of the personnel activity area can save energy.

[0034] Furthermore, the personnel activity area refers to the area where personnel mainly carry out activities.

[0035] In another embodiment, the second air outlet is disposed at the top of the building.

By setting the first stop gate 21, the second stop gate 22, the third stop gate 23 and the fourth stop gate 24, the switching control of the air outlet of the first air outlet or the air outlet of the second air outlet is realized.

[0047] Further, the stop gate is opened to connect the pipeline where it is located with the air conditioning unit. The stop gate is closed to block the connection between the pipeline where it is located and the air conditioning unit.

[0048] Furthermore, the first stop gate 21, the second stop gate 22, the third stop gate 23 and the fourth stop gate 24 are all plate gates.

[0049] Furthermore, the first stop gate 21, the second stop gate 22, the third stop gate 23 and the fourth stop gate 24 all have a controller, which is communicated with the control system, and the control system controls the switching of the first stop gate 21, the second stop gate 22, the third stop gate 23 and the fourth stop gate 24 according to the signals of the first detection unit 41 and the second detection unit 42.

The first section 31 can rotate around its own central axis, and the second section 32 can rotate around its own central axis. By setting the first section 31 and the second section 32 to be rotatable around their own central axis, hot air or cold air can be blown out in a surrounding manner, so that people can fully feel the effect of hot air or cold air, avoid heat waste, and improve the user experience.

[0051] Furthermore, the rotation of the first section 31 and the second section 32 is rotation around their respective central axes in a vertical plane.

[0052] Furthermore, the first section 31 and the second section 32 are connected to form an airflow guide tube.

[0054] Further, the first driving part is arranged at the bottom of the first section 31, and the first section 31 is driven to rotate by the rotation of the first driving part. The second driving part is arranged at the bottom of the second section 32 and the top of the first section 31, and the second section 32 is driven to rotate by the rotation of the second driving part.

[0058] When the first section 31 rotates, the second section 32 is stationary, and when the second section 32 rotates, the first section 31 is stationary. The rotation of the first section 31 and the rotation of the second section 32 are independent of each other, that is, the rotation of the first section 31 and the rotation of the second section 32 do not interfere with each other, reducing the rotation area and achieving the effect of reducing rotation energy consumption.
