It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein.

Example 1
In accordance with an embodiment of the present invention, there is provided a method embodiment of a control method of an air conditioner, it is noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system, such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that presented herein.
Fig. 1 is a flowchart of a control method of an air conditioner according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
and step S102, determining that the target air conditioner enters a power limiting mode, wherein the power limiting mode is a mode of limiting the running power.
In the above embodiment, the target air conditioner is an air conditioner having a function of limiting power. The power limit mode is a mode that limits the operating power of the air conditioner.
For example, in an area where the power supply facility is relatively lagged, the voltage may be too low, the power supply may not be stable, or the power supply may be inconvenient, and the air conditioner may be controlled to enter the power limiting mode to ensure the normal and smooth operation of the air conditioner.
And step S104, acquiring the actual electric parameters of the target air conditioner in the power limiting mode.
And step S106, determining a target control mode of the target air conditioner based on the actual electrical parameters.
And step S108, controlling the target air conditioner to operate according to the target control mode.
As can be seen from the above, in the embodiment of the present invention, when it is determined that the target air conditioner enters the power limiting mode, the actual electrical parameter of the target air conditioner may be obtained in the power limiting mode; determining a target control mode of the target air conditioner based on the actual electrical parameters; the target air conditioner is controlled to operate according to the target control mode, the purpose that the air conditioner operates according to the power limiting mode when the preset condition is met by setting the power limiting mode for the air conditioner is achieved, and the technical effect of improving the reliability of the air conditioner is achieved.
Therefore, the control method of the air conditioner provided by the embodiment of the invention solves the technical problem that the air conditioner cannot normally operate because the operating power of the air conditioner cannot be effectively controlled in the related art.
In the embodiment of the invention, the limited power mode is entered through two modes, wherein one mode is manually controlled to enter the limited power mode, and the other mode is automatically entered into the limited power mode. These two modes are explained in detail below.
On one hand, in the step S102, determining that the target air conditioner enters the power limited mode may include: and when the response operation of the target air conditioner to the power limiting signal is detected when the power limiting signal is received, determining that the target air conditioner enters a power limiting mode.
The above-described manner is a manual manner to enter a limited power mode, i.e., a manual control mode. For example, a special function key can be arranged on a remote controller matched with a target air conditioner, and a user can send out a corresponding remote control signal according to the actual requirement of the user; and after the internal machine of the target air conditioner receives the power limiting signal, if the external machine of the target air conditioner is detected to enter the power limiting mode, determining that the target air conditioner enters the power limiting mode.
On the other hand, in the step S102, determining that the target air conditioner enters the power limited mode includes: acquiring an actual input voltage value of a target air conditioner; upon determining that the actual input voltage value is lower than the predetermined voltage value, it is determined that the target air conditioner enters the power limited mode.
The above mode is an automatic control mode. Under this automatic control mode, the mainboard of target air conditioner can detect actual input voltage value, can reduce the compressor operating frequency of target air conditioner when actual input voltage value is crossed lowly, realizes the power reduction operation to avoid the electric wire netting load overweight, influence other electrical apparatus normal use.
It should be noted that, for a target air conditioner with a power limit mode, a plurality of power limit gears are set in advance in its control program, for example, 2 power limit gears P are set in its control program1/P2Corresponding maximum operating current target value I1/I2And the current value of the whole machine running corresponding to the gear does not exceed the preset current target value. For example, the maximum operation current of the whole machine of the target air conditioner is 10A (the current value is the current measured under the highest frequency under the nominal working condition), P1The lower limit power of the gear is 70 percent of the maximum power, P2The lower limit power of the mode is 50% of the maximum power, and the current value I set in the program is1=7A,I25A. Since the overall power increases and decreases as the frequency of the compressor increases, it is an effective method to control the overall power by adjusting the frequency.
Specifically, in the artificial control mode, the actual electrical parameter is an actual input current value of the target air conditioner, and the determining the target control mode of the target air conditioner based on the actual electrical parameter may include: determining a power limit gear of the target air conditioner based on the power limit signal; acquiring a set current value corresponding to a limited power gear; and determining a target control mode of the target air conditioner based on the actual input current value and the set current value.
For example, when the user sends a power-limiting signal through a button on the remote controller, the target air conditioner transmits the power-limiting signal to the external unit of the target air conditioner after receiving the power-limiting signal, so that the external unit of the target air conditioner enters the power-limiting mode. At the moment, the target air conditioner determines a power limit gear of the target air conditioner based on the power limit signal, and then obtains a set current value of the power limit gear, so that a target control mode of the target air conditioner is determined based on an actual input current value and the set current value.
The determining the target control mode of the target air conditioner based on the actual input current value and the set current value may include: when the actual input current value is larger than the set current value, determining a target control mode to reduce the current operating frequency of the target air conditioner; when the actual input current value is not greater than the set current value, judging whether the actual input current value is not less than the current difference value between the set current value and the preset current value, and when the actual input current value is not less than the current difference value, determining that the target control mode is to maintain the current operating frequency of the target air conditioner; and when the actual input current value is smaller than the current difference value, determining the target control mode as that the target air conditioner is controlled to exit the limited power mode.
For example, when a P1 mode signal transmitted by a remote controller is received, the operation frequency of the target air conditioner is controlled as follows: 1) actual detection current IPractice of(i.e., actual input current value)>I1(i.e., set current value), i.e., IPractice of>7A, reducing the current running frequency; 2) i is1Not less than the actual detection current IPractice ofNot less than I1-0.5A, i.e. 7A not less than actual detection current IPractice ofThe current running frequency is kept at more than or equal to 6.5A; 3) i is1-0.5A>Actual detection current IPractice ofI.e. 6.5A>Actual detection current IPractice ofAt this time, the power is low, the power requirement is met, the control is carried out according to normal logic, and the power limiting control is not carried out.
P2 mode power logic control, and so on. And will not be described in detail herein.
Specifically, in the automatic control mode, the actual electrical parameter is an actual input voltage value of the target air conditioner, and the determining the target control mode of the target air conditioner based on the actual electrical parameter may include: acquiring a rated operation voltage value and a target operation voltage value of a target air conditioner, wherein the target operation voltage value is a voltage value of the target air conditioner operating in a power-limiting mode; and determining a target control mode of the target air conditioner based on the actual input voltage value, the rated operation voltage value and the target operation voltage value.
For example, in the automatic control mode, the main board of the target air conditioner detects the actual input voltage value, and when the actual input voltage value is too low, the operation frequency of the compressor is reduced, so that the power reduction is realized, and the influence on the normal use of other electrical appliances caused by the overweight load of the power grid is avoided.
It is to be noted thatThe target air conditioner having the limited power mode may previously set a target operation voltage target value (i.e., a target operation voltage value) U in a control program thereof3/U4,U3(i.e., the first voltage value) is greater than U4(i.e., the second voltage value).
The determining the target control mode of the target air conditioner based on the actual input voltage value, the rated operation voltage value and the target operation voltage value may include: when the actual input voltage value is not less than the rated operation voltage value, determining a target control mode to keep the current operation frequency of the target air conditioner; when the actual input voltage value is smaller than the rated operation voltage value, judging whether the actual input voltage value is not smaller than a first voltage value in the target operation voltage value, and when the actual input voltage value is not smaller than the first voltage value, determining that the target control mode is to prohibit the current operation frequency of the target air conditioner from rising; when the actual input voltage value is smaller than the first voltage value, judging whether the actual input voltage value is not smaller than a second voltage value in the target operation voltage value, and when the actual input voltage value is not smaller than the second voltage value, determining that the target control mode is to reduce the current operation frequency of the target air conditioner, wherein the first voltage value is larger than the second voltage value; and when the actual input voltage value is smaller than the second voltage value, determining the target control mode as that the target air conditioner operates according to the lowest operation frequency.
For example, a normal operation default voltage (i.e., rated voltage) U of the target air conditioner is 230V, U3=200V,U4180V, the main board of the target air conditioner detects a voltage (i.e., an actual input voltage value) U in real timeFruit of Chinese wolfberry. When the target air conditioner enters the automatic control mode, the operation frequency is executed according to the following conditions: 1) when U is turnedFruit of Chinese wolfberryGreater than or equal to U, i.e. UFruit of Chinese wolfberryThe voltage is more than or equal to 230V, the voltage meets the requirement, and the frequency of the compressor runs in a normal mode; 2) when U is turned>UFruit of Chinese wolfberry≥U3I.e. 230V>The Uactually is more than or equal to 200V, and the frequency of the compressor is not allowed to rise; 3) when U3>U is greater than or equal to U4, i.e. 200V>The Uactually is more than or equal to 180V, and the frequency of the compressor is reduced; 4) when U is true<U4, i.e. Ushi<180V, the compressor frequency remains the lowest frequency operation.
In the embodiment of the present invention, the current value and the voltage value in the above description are used only for understanding logic.
Fig. 2 is a flowchart illustrating an alternative control method of an air conditioner according to an embodiment of the present invention, and as shown in fig. 2, after a target air conditioner is started to operate, it is determined whether a power-limited signal is received; if yes, determining that the target air conditioner is in an artificial control mode; otherwise, the target air conditioner is determined to be in the automatic control mode. In the artificial control mode, the following control logic is executed: 1) actual detection current IPractice of>I1I.e. IPractice of>7A, reducing the current running frequency; 2) i is1Not less than the actual detection current IPractice ofNot less than I1-0.5A, i.e. 7A not less than actual detection current IPractice ofThe current running frequency is kept at more than or equal to 6.5A; 3) i is1-0.5A>Actual detection current IPractice ofI.e. 6.5A>Actual detection current IPractice ofAt the moment, the power is low, the power requirement is met, the control is carried out according to normal logic, and the power limiting control is not carried out; in the automatic control mode, the following control logic is executed: 1) when U is turnedFruit of Chinese wolfberryGreater than or equal to U, i.e. UFruit of Chinese wolfberryThe voltage is more than or equal to 230V, the voltage meets the requirement, and the frequency of the compressor runs in a normal mode; 2) when U is turned>UFruit of Chinese wolfberry≥U3I.e. 230V>The Uactually is more than or equal to 200V, and the frequency of the compressor is not allowed to rise; 3) when U3>U is greater than or equal to U4, i.e. 200V>The Uactually is more than or equal to 180V, and the frequency of the compressor is reduced; 4) when U is true<U4, i.e. Ushi<180V, the compressor frequency remains the lowest frequency operation. And finally, controlling the target air conditioner to shut down and exiting the power limiting mode.
As can be seen from the above, in the embodiment of the present invention, a limit — power logic control method is added in the air conditioner program, for example, an artificial control mode and an automatic control mode; under the artificial control mode, power gears are set in a program, different power gears correspond to different current preset values, a user transmits a signal to a main board through a remote controller, and the user controls the running frequency of the whole machine by detecting the current value of the whole machine, so that the purpose of limiting power is achieved. In the automatic control mode, the main board program detects the current input voltage and realizes the power reduction values of different gears according to different voltage value conditions.
Therefore, the control method of the air conditioner provided by the embodiment of the invention can reduce the running power of the air conditioner through program control, can play a role in energy saving, and can lead a user to select different power gears or automatically control the reduction of the power through a program according to the local power supply condition, so that the applicability of the air conditioner is wider, and the limitation of the power supply use condition is reduced. Has the following beneficial effects: 1) the running power of the air conditioner is reduced, so that the air conditioner can be normally used in a severe power supply environment; 2) the running energy consumption of the air conditioner is reduced, and the air conditioner is comfortable and energy-saving.
