And by utilizing the form of the corresponding setting sub-interface, different air conditioning units can be managed and controlled more orderly. In some embodiments of the present invention, the control menu of the sub-interface, which can be input or selected by the user, may generate corresponding controls according to different functions of different forms of air conditioners, such as no "refreshing mode" start/stop, "left/right wind direction" adjustment, and other controls.
Third embodiment
Referring to fig. 7, the air conditioning system of the present embodiment is provided with two air duct type indoor units 11 in parallel at different positions in a second room to condition air in the same space (the second room). Since the two air duct type indoor units 11 are disposed at different positions, the temperature measurement results (environmental parameter measurement results in the present embodiment) of the indoor temperature of the second room are different.
Aiming at different temperature measurement results, the control part 3 can comprehensively consider the temperature measurement results of the two air duct type indoor units 11, and the temperature measurement result closer to the real indoor temperature is calculated and obtained by adjusting the weight of the data.
In the present embodiment, the two air duct type indoor units 11 are installed in the same space (room two) and arranged to air-condition the same space, and since the air in the same space circulates, in order to air-condition the space, it is necessary to perform the air-conditioning by comprehensively using the two air duct type indoor units 11 in the space, and the control commands of the two air duct type indoor units 11 affect each other. For this purpose, the control unit 3 analyzes the obtained control command, and feeds back the control command to each of the two duct type indoor units 11 via the router 4 and the first communication channels 41 of the two wireless communication modules 210, respectively, to control the operation states of each of the two duct type indoor units 11 based on the temperature measurement result.
In the present embodiment, the control of two or more outdoor units 10 installed in the same room (room two) in the corresponding indoor units is also performed by the control unit 3 in a unified manner. Specifically, the two outdoor units 10 connected to the second room may obtain different environmental parameter measurement results for the outdoor environment, and in this embodiment, obtain different temperature measurement results for the current outdoor temperature. For example, one of the two outdoor units 10 is disposed at the south side of the second room, and the other is disposed at the north side of the second room, and the current outdoor temperatures measured by the different outdoor units 10 are different due to different lighting conditions, so how to obtain more accurate measurement results is a problem to be solved. Therefore, in the present embodiment, the control unit 3 can obtain a more accurate determination of the outdoor temperature by using a numerical average, a weighted average, or any other suitable calculation method based on the temperature measurement results of the two outdoor units 10 connected to both the rooms and the atmospheric temperature (network environment parameter data) of the area acquired from the internet 6 via the second communication channel 42.
In some embodiments of the present invention, two air duct type indoor units 11 disposed in the same room may be formed as air duct type indoor units 11 with different air outlet and air inlet structures. Referring to fig. 8, the two duct type indoor units 11 disposed in the same room include a side-outlet type duct type indoor unit 11a and a bottom-outlet type duct type indoor unit 11 b. The side-outlet type air duct type indoor unit 11a may be a lower-outlet type air duct or a side-outlet type air duct, the lower-outlet type air duct type indoor unit 11b is a side-outlet type air duct, and an outlet air path of the side-outlet type air duct type indoor unit 11a is matched with an inlet air path of the lower-outlet type air duct type indoor unit 11b to form a circulation flow path of air.
In some embodiments, the lower outlet duct type indoor unit 11b may be disposed on the north side of the room, and the side outlet duct type indoor unit 11a may be disposed on the south side of the room. The air heated by the side air outlet type air pipe type indoor unit 11a is heated by the lower air outlet type air pipe type indoor unit 11b and then blown out to the ground, and after heat exchange with the room air is completed, the air is sucked by the side air outlet type air pipe type indoor unit 11a and sent out, so that a circulation air path with a more excellent heating effect is formed. By utilizing the cooperation between the side-outlet type air duct type indoor unit 11a and the lower-outlet type air duct type indoor unit 11b and the unified control of the controller 3, a circulation air path with higher heating efficiency can be effectively formed. Similarly, the cooling efficiency of the air conditioning unit can also be improved by adjusting the air inlet and outlet modes, the setting positions or the control methods of the different air pipe type indoor units 11.
In this embodiment, for controlling different duct type indoor units 11 in the same room, in the terminal application of the mobile communication terminal 5-2, a plurality of sub-controls may be generated under the control corresponding to the same room on the graphical user interface, so as to control each duct type indoor unit 11 in the room by using the sub-controls corresponding to the duct type indoor units 11 one to one.
