Referring to fig. 3, fig. 3 is a schematic flowchart of a first embodiment of a method for controlling an air conditioner according to the present invention, the method comprising:
and step S10, receiving a control instruction triggered by a user, and detecting whether the air conditioner starts a partitioned temperature control mode according to the control instruction.
The user can control the air conditioner through the remote controller or a touch panel on the air conditioner, and can also realize the control of the air conditioner through a remote control application program on the user terminal. The air conditioner receives a control instruction triggered by a user in real time in a cooling or heating mode, and obtains relevant parameters of the air conditioner, such as a working mode, an air supply temperature, an air supply speed and the like through analysis of the control instruction. When the air conditioner is in a cooling or heating mode, whether the air conditioner receives a zone temperature control command is detected, and whether the zone temperature control mode is started or not is detected accordingly.

For example, if the air conditioner has 2 left and right air outlets, the partitioned temperature control mode needs to be started in the air conditioner refrigeration mode, the user selects the left air outlet first, sets the air supply temperature of the left air outlet to 28 ℃, sets the air supply speed to be the first level, selects the right air outlet again, sets the air supply temperature of the right air outlet to be the normal temperature air, sets the air supply speed to be the second level, and after the user sets the air supply requirements corresponding to the left and right air outlets, the air conditioner can acquire the air supply requirements corresponding to the left and right air outlets.
Of course, the above examples are merely illustrative and do not constitute a specific limitation of the present invention. The air conditioner can also be provided with a remote controller with the function adaptive to the air conditioner, and the air supply requirement of each air outlet can be set independently through the remote controller.
And step S30, respectively controlling the opening of the valve in each air duct according to the acquired air supply requirements corresponding to each air outlet, so that the wind energy blown out from each air duct meets the air supply requirements corresponding to each air outlet, and the partition temperature control of the air conditioner is realized.
After the air supply requirements corresponding to the air outlets are obtained, the opening degrees of the valves in the air channels are respectively controlled according to the obtained air supply requirements corresponding to the air outlets. Specifically, the step S30 includes:
step S301, if the air supply requirement corresponding to the first air outlet is normal temperature air, controlling a valve in the air duct corresponding to the first air outlet to close.
In step S302, if the air supply requirement corresponding to the second air outlet is very warm air, the valve in the air duct corresponding to the second air outlet is controlled to open.
It should be noted that, the "first outlet" and the "second outlet" herein do not denote any outlet, but are a generic name of a type of outlet, where the first outlet denotes an outlet whose air supply demand is normal temperature air, and the second outlet denotes an outlet whose air supply demand is very temperature air, and may be 1, 2, 3, and so on. Continuing to explain based on the above example, the temperature of the air supplied by the air conditioner to the left air outlet (i.e., the second air outlet) is 28 ℃; the air supply temperature of right side air outlet (being first air outlet) is normal atmospheric temperature wind, then need control the valve piece in the wind channel that left side air outlet corresponds and close, and control the valve piece in the wind channel that right side air outlet corresponds and open, the valve piece that left side air outlet corresponds from this closes, the refrigerant can not flow to the indoor heat exchanger that corresponds through this valve piece, lead to the indoor heat exchanger in this wind channel to be unable to carry out the heat transfer, the wind that blows off in this wind channel is normal atmospheric temperature wind, and the valve piece that right side air outlet corresponds is opened, the refrigerant can flow to the indoor heat exchanger that corresponds through this valve piece and carry out the heat transfer, the wind that leads to blowing off in this wind channel is cold wind, thereby realize the.
In this embodiment, after detecting that the air conditioner is in the district accuse temperature mode, control the aperture of the valve member in each wind channel to the refrigerant flow of different indoor heat exchangers of control flow through makes the refrigerating output or the heating output of the indoor heat exchanger in different wind channels different, thereby has realized the zone control of air conditioner, has satisfied the air supply demand of different indoor regions, has improved the use travelling comfort of air conditioner.
Further, referring to fig. 4, fig. 4 is a flowchart illustrating a control method of an air conditioner according to a second embodiment of the present invention. Based on the above embodiment, in this embodiment, the air supply requirement further includes an air supply speed, and the method further includes:
and step S40, respectively controlling the operating frequency of the indoor fans corresponding to the first air outlet and the second air outlet according to the acquired air supply speed corresponding to each air outlet.
In this embodiment, the air supply requirement further includes an air supply speed, and when the air supply corresponding to each air outlet is obtained as normal temperature air or non-normal temperature air, the air supply speed corresponding to each air outlet needs to be obtained to control the operating frequency of the indoor fan corresponding to each air outlet. Specifically, the step S40 includes:
step S401, if the air supply speed of the first air outlet is increased or decreased, controlling the operating frequency of the indoor fan corresponding to the first air outlet to be correspondingly increased or decreased.
And S402, if the air supply speed of the second air outlet is increased or decreased, controlling the operating frequency of the indoor fan corresponding to the second air outlet to be correspondingly increased or decreased.
Because each air channel of the air conditioner is provided with the indoor fan which can be independently controlled, the indoor fan can adjust the operation frequency according to the air supply speed set by a user, so that the air speed blown out from the air outlet reaches the air supply speed. In the zone temperature control mode of the air conditioner, a user sets respective air supply speed for each air outlet independently, so that different indoor areas have different air outlet effects. For example, when the first air outlet sends out normal temperature air and the second air outlet sends out non-normal temperature air, the air supply speed of the first air outlet is increased, the air supply speed of the second air outlet is reduced, air circulation of an indoor area corresponding to the first air outlet is increased, and influence of cold air or hot air blown out by the second air outlet is avoided, so that the indoor areas corresponding to the first air outlet and the second air outlet achieve higher comfort.
In this embodiment, the operation frequency of the indoor fans corresponding to the first air outlet and the second air outlet is controlled respectively by acquiring the air supply speeds corresponding to the first air outlet and the second air outlet, so that air supply control is performed on different partitions more finely, and each indoor area achieves higher comfort.
Further, referring to fig. 5, fig. 5 is a flowchart illustrating a control method of an air conditioner according to a third embodiment of the present invention. Based on the above embodiment, in this embodiment, the air supply requirement further includes an air supply temperature, and if the air supply requirement corresponding to the second air outlet is very warm air, the step S302 controls the valve in the air duct corresponding to the second air outlet to open, including:
and step S50, controlling the opening degree of a valve in the air duct corresponding to the second air outlet according to the air supply temperature of the second air outlet.
Because the air conditioner can control the first air outlet and the second air outlet to respectively blow out normal temperature air and extraordinary temperature air in a zone temperature control mode, the opening degree of a valve piece in the air duct corresponding to the second air outlet needs to be further controlled according to the air supply temperature of the extraordinary temperature air at the second air outlet, so that the flow of the refrigerant flowing through the indoor heat exchanger in the air duct is adjusted, and the refrigerating capacity or the heating capacity of the indoor heat exchanger is controlled.
Specifically, the step S50 includes:
step S501, obtaining the indoor environment temperature of the indoor area corresponding to the second air outlet.
In this embodiment, the air conditioner may set a temperature detection device at each air outlet, and obtain the indoor ambient temperature at each air outlet through each temperature detection device. After the air supply temperature corresponding to the second air outlet is obtained, the indoor environment temperature of the indoor area corresponding to the second air outlet is obtained through the temperature detection device at the second air outlet.
Step S502, calculating the difference value between the air supply temperature of the second air outlet and the indoor environment temperature.
And step S503, adjusting the opening degree of a valve in the air duct corresponding to the second air outlet according to the absolute value of the difference value and a preset threshold value.
And comparing the air supply temperature of the second air outlet with the indoor environment temperature to obtain the difference value of the air supply temperature of the second air outlet and the indoor environment temperature. And after the difference value is obtained, comparing the absolute value of the difference value with a preset threshold value, and adjusting the opening degree of a valve in the air duct corresponding to the second air outlet according to the comparison result. For example, when the indoor heat exchanger corresponding to the second air outlet is in the cooling mode, if the absolute value of the difference is smaller than the preset threshold, it indicates that the indoor environment temperature slightly fluctuates above and below the air supply temperature, and the opening degree of the valve in the air duct corresponding to the second air outlet can be kept unchanged within the allowable fluctuation range; if the absolute value of the difference is greater than or equal to the preset threshold value, it is indicated that the difference between the indoor environment temperature and the air supply temperature is relatively far, the refrigerating capacity of the indoor heat exchanger corresponding to the second air outlet needs to be adjusted, at the moment, the air supply temperature of the second air outlet and the indoor environment temperature are further judged, and if the air supply temperature of the second air outlet is greater than the indoor environment temperature, the opening degree of a valve in an air duct corresponding to the second air outlet is controlled to be reduced; and if the air supply temperature of the second air outlet is lower than the indoor environment temperature, controlling the opening degree of a valve in the air duct corresponding to the second air outlet to increase. When the indoor heat exchanger corresponding to the second air outlet is in a heating mode, if the absolute value of the difference is smaller than a preset threshold value, the indoor environment temperature is slightly fluctuated above and below the air supply temperature, and the opening degree of a valve in an air duct corresponding to the second air outlet can be kept unchanged within an allowable fluctuation range; if the absolute value of the difference is greater than or equal to the preset threshold value, it is indicated that the difference between the indoor environment temperature and the air supply temperature is relatively far, the refrigerating capacity of the indoor heat exchanger corresponding to the second air outlet needs to be adjusted, at the moment, the air supply temperature of the second air outlet and the indoor environment temperature are further judged, and if the air supply temperature of the second air outlet is greater than the indoor environment temperature, the opening of a valve in an air duct corresponding to the second air outlet is controlled to be increased; and if the air supply temperature of the second air outlet is lower than the indoor environment temperature, controlling the opening degree of a valve in the air duct corresponding to the second air outlet to be reduced. The preset threshold value may be any positive number, and is preferably 0 to 3 ℃.
In this embodiment, the opening degree of the valve member in the air duct corresponding to the second air outlet is controlled by obtaining the air supply temperature of the second air outlet, so that the heat exchange amount of the indoor heat exchanger in the air duct corresponding to the second air outlet is adjusted, the control of the air supply temperature of the second air outlet is realized, and the air is blown out from the second air outlet to meet the user requirements.
Further, based on the above embodiment, in this embodiment, after the step S10 detects whether the air conditioner starts the partition temperature control mode according to the control instruction, the method includes:
and step S60, if the condition that the air conditioner starts the partitioned temperature control mode is not detected, controlling the air conditioner to maintain a cooling or heating mode.
