The embodiment of the present application exemplifies the method for controlling an air conditioner by controlling the first air conditioner and the second air conditioner shown in fig. 1.

Referring to fig. 2, a method for controlling an air conditioner includes:

s201, under the condition that the temperature of the first room and the temperature of the second room are simultaneously increased or decreased, the first indoor temperature of the first room, the second indoor temperature of the second room and the common set temperature of the first room and the second room are obtained.

The first room and the second room may be heat exchanged through the opened door and/or window, or through the pedestrian passageway. In a specific application scenario, the first room and the second room may be a bedroom and a living room, respectively, or the first room and the second room may be two offices, respectively.

In a home or office setting, a set temperature is usually set, and a plurality of rooms in the home or office setting are all adjusted to the set temperature, and such a set temperature is a common set temperature.

The case where both of the first indoor temperature of the first room and the second indoor temperature of the second room do not reach the set temperature may include: the first indoor temperature of the first room is higher than the set temperature, the second indoor temperature of the second room is lower than the set temperature, at this time, the first room needs to be cooled, and the second room needs to be heated, or the first indoor temperature of the first room is lower than the set temperature, the second indoor temperature of the second room is higher than the set temperature, at this time, the first room needs to be heated, and the second room needs to be cooled; the first indoor temperature of the first room and the second indoor temperature of the second room are both greater than the set temperature, and at the moment, the first room and the second room need to be cooled; both the first indoor temperature of the first room and the second indoor temperature of the second room are lower than the set temperature, and at this time, the first room and the second room need to be heated.

The method for controlling the air conditioner is suitable for the condition that the first temperature of the first room and the second indoor temperature of the second room are both larger than or smaller than the set temperature.

In a specific application, the first indoor temperature of the first room can be obtained by a temperature sensor arranged on the first air conditioner of the first room, and can also be obtained by other electronic devices with temperature detection functions arranged in the first room; the second indoor temperature of the second room may be obtained by a temperature sensor provided in the second air conditioner of the second room, or may be obtained by other electronic devices having a temperature detection function provided in the second room. The electronic device with temperature detection function may be an independent intelligent thermometer, and may also be an intelligent switch panel with temperature detection function. The embodiment of the present application does not limit the specific obtaining manner of the first indoor temperature and the second indoor temperature, and a person skilled in the art can select a suitable prior art and obtain the first indoor temperature and the second indoor temperature according to actual conditions.

The set temperature can be set by a user, and can also be a temperature which is in accordance with the comfort level of a human body or in accordance with health by utilizing big data, artificial intelligence and the like. The obtaining mode of the set temperature is not specifically limited in the embodiment of the present application, and a person skilled in the art can select a suitable prior art to obtain the set temperature according to an actual situation.

S202, a first temperature difference value between the set temperature and the first indoor temperature and a second temperature difference value between the set temperature and the second indoor temperature are obtained.

S203, under the condition that the absolute value of the first temperature difference and the absolute value of the second temperature difference are both larger than the absolute value of the threshold temperature, obtaining a third temperature difference between the first indoor temperature and the second indoor temperature.

The absolute value of the threshold temperature here may be 2 ℃, 3 ℃ or 4 ℃.

S204, adjusting the temperature adjusting power of the first air conditioner in the first room and the second air conditioner in the second room according to a fourth temperature difference value of the set temperature difference value and the third temperature difference value, so that the fourth temperature difference value approaches to zero.

The fourth temperature difference approaches zero, which means that the fourth temperature difference always has a tendency of changing to zero, and in practical application, the fourth temperature difference fluctuates around zero, and the fourth temperature difference may be greater than zero, and may also be smaller than zero; alternatively, it is determined that the fourth temperature difference approaches zero when the fourth temperature difference fluctuates within a range of-1 ℃ to 1 ℃ (inclusive).

The temperature difference value of the first indoor temperature of the first room and the second indoor temperature of the second room, which is detected for the first time, may be determined as the set temperature difference value when the method for controlling an air conditioner is performed for the first time.

The temperature adjusting powers of the first air conditioner and the second air conditioner refer to a first temperature adjusting power of the first air conditioner and a second temperature adjusting power of the second air conditioner; in a scene that the first room and the second room are heated simultaneously, first temperature adjusting power of a first air conditioner refers to heating power of the first air conditioner, and second temperature adjusting power of a second air conditioner refers to heating power of the second air conditioner; in a scenario that the first room and the second room are cooled simultaneously, the first temperature adjustment power of the first air conditioner refers to the cooling power of the first air conditioner, and the second temperature adjustment power of the second air conditioner refers to the cooling power of the second air conditioner.

Factors influencing the temperature adjusting power of the air conditioner comprise the frequency of an air conditioner compressor and the rotating speed of an indoor fan, for example, the higher the frequency of the air conditioner compressor is, the higher the temperature adjusting power of the air conditioner is; the higher the rotating speed of the indoor fan is, the higher the temperature adjusting power of the air conditioner is.

Further, under the condition that the absolute value of the first temperature difference is smaller than the absolute value of the second temperature difference, if the first temperature adjusting power is larger than the second temperature adjusting power, the power difference between the first temperature adjusting power and the second temperature adjusting power is positively correlated with the set temperature difference; if the first temperature adjusting power is smaller than the second temperature adjusting power, the power difference value of the second temperature adjusting power and the first temperature adjusting power is in negative correlation;

under the condition that the absolute value of the first temperature difference is larger than the absolute value of the second temperature difference, if the first temperature adjusting power is larger than the second temperature adjusting power, the power difference value of the first temperature adjusting power and the second temperature adjusting power is in negative correlation with the set temperature difference value; and if the first temperature adjusting power is smaller than the second temperature adjusting power, the power difference value of the second temperature adjusting power and the first temperature adjusting power is positively correlated.

Under the condition that the first air conditioner and the second air conditioner simultaneously heat, if the first temperature adjusting power is larger than the second temperature adjusting power, the larger temperature difference value can enable the heat of the first room to flow to the second room more, and the heating rate of the first room and the second room is improved on the whole; if the first temperature-adjusting power is less than the second temperature-adjusting power, the smaller temperature difference may cause the heat of the first room to flow to the second room less, reducing the load of the first air conditioner.

Under the condition that the first air conditioner and the second air conditioner refrigerate simultaneously, if the first temperature adjusting power is larger than the second temperature adjusting power, the larger temperature difference can enable the cold quantity (the heat quantity flows reversely) of the first room to flow to the second room more, and the heating rate of the first room and the second room is improved on the whole; if the first temperature-adjusting power is less than the second temperature-adjusting power, the smaller temperature difference may cause the heat of the first room to flow to the second room less, reducing the load of the first air conditioner.

The first temperature adjusting power of the first air conditioner and the second temperature adjusting power of the second air conditioner may be preset, for example, the temperature adjusting powers of the first air conditioner and the second air conditioner may be respectively divided into a low-level temperature adjusting power, a medium-level temperature adjusting power and a high-level temperature adjusting power, wherein the low-level temperature adjusting power is smaller than the medium-level temperature adjusting power, and the medium-level temperature adjusting power is smaller than the high-level temperature adjusting power. The first temperature regulating power is low-grade temperature regulating power, and the second temperature regulating power is low-grade temperature regulating power; or the first temperature regulating power is middle-grade temperature regulating power, and the second temperature regulating power is middle-grade temperature regulating power; or the first temperature regulating power is high-grade temperature regulating power, and the second temperature regulating power is high-grade temperature regulating power.

Or the first temperature adjusting power is determined according to the first temperature difference value, and the second temperature adjusting power is determined according to the second temperature difference value. In this case, adjusting the temperature adjustment powers of the first air conditioner in the first room and the second air conditioner in the second room according to a fourth temperature difference between the set temperature difference and the third temperature difference may include: determining first temperature adjusting power corresponding to the first temperature difference according to the corresponding relation between the temperature difference and the temperature adjusting power; determining second temperature regulating power corresponding to the second temperature difference according to the corresponding relation between the temperature difference and the temperature regulating power; adjusting the first temperature adjusting power and/or the second temperature adjusting power according to the fourth temperature difference; the adjusted first temperature adjusting power is used for controlling the first air conditioner, and the adjusted second temperature adjusting power is used for controlling the second air conditioner.

The corresponding relation between the temperature difference and the temperature adjusting power can be obtained through limited tests, for example, for one temperature difference, different temperature adjusting powers are sequentially set for the air conditioner, when the time length for eliminating the temperature difference is in accordance with expectation, the temperature adjusting power set at the moment is determined to be the temperature adjusting power corresponding to the temperature difference, in this way, the temperature adjusting power corresponding to each temperature difference is determined, the corresponding relation between the temperature difference and the temperature adjusting power is stored in a database in a one-to-one corresponding mode, and after the first temperature difference is obtained, the first temperature adjusting power corresponding to the first temperature difference can be obtained by querying the database; after the second temperature adjusting power is obtained, the second temperature adjusting power corresponding to the second temperature difference value can be obtained by querying the database.

Alternatively, the correspondence between the temperature difference and the temperature-controlled power may be realized by a controller having a function of eliminating the deviation, such as a proportional-integral-derivative (PID) controller or a linear quadratic regulator (linear quadratic regulator). Inputting the first temperature difference value into a controller with a deviation eliminating function, and obtaining first temperature adjusting power corresponding to the first temperature difference value; and inputting the second temperature difference value into a controller with a deviation eliminating function, so that second temperature adjusting power corresponding to the second temperature deviation can be obtained.

The adjusting of the temperature adjustment power of the first air conditioner in the first room and the second air conditioner in the second room includes: adjusting the first temperature adjusting power of the first air conditioner, and maintaining the second temperature adjusting power of the second air conditioner unchanged; or adjusting the second temperature adjusting power of the second air conditioner, and keeping the first temperature adjusting power of the first air conditioner unchanged; or adjusting the first temperature adjusting power of the first air conditioner and the second temperature adjusting power of the second air conditioner simultaneously.

The adjusting conditions for adjusting the first temperature adjusting power of the first air conditioner and/or the second temperature adjusting power of the second air conditioner are as follows: under the condition that the temperature of the first room and the temperature of the second room are simultaneously increased, if the first indoor temperature is higher than the second indoor temperature and the absolute value of the third temperature difference is higher than the absolute value of the set temperature difference, the first temperature adjusting power is required to be reduced and/or the second temperature adjusting power is required to be increased; if the first indoor temperature is higher than the third indoor temperature and the absolute value of the third temperature difference is smaller than the absolute value of the set temperature difference, the first temperature regulation power needs to be increased and/or the second temperature regulation power needs to be reduced;

under the condition of simultaneously cooling the first room and the second room, if the first indoor temperature is higher than the second indoor temperature and the absolute value of the third temperature difference is higher than the absolute value of the set temperature difference, the first temperature regulation power is required to be increased and/or the second temperature regulation power is required to be reduced; if the first indoor temperature is higher than the second indoor temperature and the absolute value of the third temperature difference is lower than the absolute value of the set temperature difference, the first temperature adjusting power needs to be reduced and/or the second temperature adjusting power needs to be increased.

In a specific application, a room with a relatively high indoor temperature can be determined as a first room, an air conditioner in the first room is determined as a first air conditioner, and the temperature adjusting power of the first air conditioner is determined as a first temperature adjusting power; and determining a room with lower indoor temperature as a second room, determining an air conditioner in the second room as a second air conditioner, and determining the temperature adjusting power of the second air conditioner as second temperature adjusting power.

The first temperature adjusting power and the second temperature adjusting power are adjusted according to the above manner, which is beneficial to making the fourth temperature difference approach to zero, that is, in the process of simultaneously heating or cooling the first room and the second room, the third temperature difference between the first room temperature and the second room temperature is kept unchanged.

Referring to fig. 3, adjusting the first temperature-adjusting power and the second temperature-adjusting power according to the fourth temperature difference includes:

and S301, carrying out differential processing on the fourth temperature difference value to obtain a differential result.

S302, under the condition that the first temperature adjusting power needs to be improved, the adjusted first temperature adjusting power is determined according to the sum of the first temperature adjusting power and the absolute value of the differential result.

For example, the sum of the first temperature adjustment power and the absolute value of the differentiation result is directly added is determined as the first temperature adjustment power after temperature adjustment; alternatively, the sum of the first temperature adjustment power and the absolute value of the differentiation result is determined as the adjusted first temperature adjustment power.

S303, under the condition that the first temperature adjusting power needs to be reduced, determining the adjusted first temperature adjusting power according to the difference between the first temperature adjusting power and the absolute value of the differential result.

For example, the difference between the first temperature-control power and the absolute value of the derivative result is directly subtracted from the first temperature-control power; or, the difference of the weighted subtraction of the first temperature-adjusting power and the absolute value of the differentiation result is determined as the adjusted first temperature-adjusting power.

S304, under the condition that the second temperature adjusting power needs to be improved, the adjusted second temperature adjusting power is determined according to the sum of the second temperature adjusting power and the absolute value of the differential result.

For example, the sum of the second temperature adjustment power and the absolute value of the differentiation result is directly added as the adjusted second temperature adjustment power; alternatively, the sum of the second temperature control power and the absolute value of the differentiation result is determined as the adjusted second temperature control power.

S305, under the condition that the second temperature adjusting power needs to be reduced, the adjusted second temperature adjusting power is determined according to the difference between the second temperature adjusting power and the absolute value of the differential result.

For example, the difference of the direct subtraction of the absolute value of the derivative result from the second temperature control power is determined as the second temperature control power after temperature control; or, the difference of the weighted subtraction of the second temperature control power and the absolute value of the differentiation result is determined as the adjusted second temperature control power.

By adopting the technical scheme, the first temperature adjusting power and the second temperature adjusting power can be adjusted.

For example, when the temperature adjustment powers of the first air conditioner and the second air conditioner are adjusted according to the first temperature difference and the fourth temperature difference, the temperature adjustment powers of the first air conditioner and the second air conditioner may be positively correlated with the absolute value of the first temperature difference.

Under the condition that the temperature adjusting powers of the first air conditioner and the second air conditioner are adjusted according to the second temperature difference and the fourth temperature difference, the temperature adjusting powers of the first air conditioner and the second air conditioner can be positively correlated with the absolute value of the second temperature difference.

The embodiment of the present application exemplifies the method for controlling an air conditioner by controlling the first air conditioner and the second air conditioner shown in fig. 1.

As shown in fig. 4, the method for controlling the air conditioner includes:

s401, under the condition that the temperature of the first room and the temperature of the second room are simultaneously increased or decreased, the first indoor temperature of the first room, the second indoor temperature of the second room and the common set temperature of the first room and the second room are obtained.

S402, obtaining a first temperature difference value between the set temperature and the first indoor temperature and a second temperature difference value between the set temperature and the second indoor temperature.

And S403, obtaining a third temperature difference value between the first indoor temperature and the second indoor temperature under the condition that the absolute value of the first temperature difference value and the absolute value of the second temperature difference value are both larger than the absolute value of the threshold temperature.

S404, adjusting the temperature adjusting power of the first air conditioner in the first room and the second air conditioner in the second room according to a fourth temperature difference value of the set temperature difference value and the third temperature difference value, so that the fourth temperature difference value approaches to zero.

S405, under the condition that the absolute value of the first temperature difference and/or the absolute value of the second temperature difference is smaller than or equal to the absolute value of the threshold temperature, determining a first temperature regulation rate positively correlated with the first temperature difference and a second temperature regulation rate positively correlated with the second temperature difference, and enabling the difference between a first ratio of the first temperature difference and the first temperature regulation rate and a second ratio of the second temperature difference and the second temperature regulation rate to be within a preset difference range.

The first tempering rate refers to a rate at which a first room temperature of the first room is increased or decreased, and the second tempering rate refers to a rate at which a second room temperature of the second room is increased or decreased.

A first ratio of the first temperature difference to the first temperature adjustment rate may reflect a time period required for the first indoor temperature of the first room to reach the set temperature under the adjustment action of the first air conditioner; a second ratio of the second temperature difference to the second temperature adjustment rate can reflect a time period required for the second indoor temperature of the second room to reach the set temperature under the adjustment action of the second air conditioner; the difference between the first ratio and the second ratio is within a preset difference range, which can indicate that the time length required for the first indoor temperature of the first room to reach the set temperature is approximately the same as the time length required for the second indoor temperature of the second room to reach the set temperature.

The larger the preset difference range is, the more likely the fluctuation of the indoor temperatures of the first room and the second room around the set temperature is to be large, and particularly, the fluctuation of the indoor temperature around the set temperature is larger in the room in which the indoor temperature first reaches the set temperature. The preset difference range is not specifically limited in the embodiment of the application, and a person skilled in the art can adaptively select the preset difference range meeting the requirement according to the requirement on the indoor temperature fluctuation.

In general, the higher the first temperature adjusting power of the first air conditioner is, the higher the upper limit value of the first temperature adjusting rate is; the lower the first temperature adjusting power of the first air conditioner is, the lower the upper limit value of the first temperature adjusting speed is; the larger the volume of the first room is, the smaller the upper limit value of the first temperature regulation rate is, and the smaller the volume of the first room is, the larger the upper limit value of the first temperature regulation rate is; the higher the second temperature adjusting power of the second air conditioner is, the larger the upper limit value of the second temperature adjusting speed is; the lower the second temperature adjusting power of the second air conditioner is, the lower the upper limit value of the second temperature adjusting speed is; the larger the volume of the second room, the smaller the upper limit value of the second temperature adjustment rate, and the smaller the volume of the second room, the larger the upper limit value of the second temperature adjustment rate.

Optionally, determining a first attemperation rate positively correlated to the first temperature difference and a second attemperation rate positively correlated to the second temperature difference comprises:

determining the temperature regulation rate of a second room corresponding to second temperature regulation power of a second air conditioner as a second temperature regulation rate under the condition that the absolute value of the first temperature difference is smaller than the absolute value of the second temperature difference; determining a first temperature regulation rate corresponding to the first temperature difference according to a second ratio of the second temperature difference to the second temperature regulation rate, wherein the difference between the first ratio and the second ratio is within a preset difference range;

Alternatively, determining a first attemperation rate positively correlated to the first temperature difference and a second attemperation rate positively correlated to the second temperature difference comprises:

determining the temperature regulation rate of a second room corresponding to second temperature regulation power of a second air conditioner as a second temperature regulation rate under the condition that the absolute value of the first temperature difference is larger than the absolute value of the second temperature difference; determining a first temperature regulation rate corresponding to the first temperature difference according to a second ratio of the second temperature difference to the second temperature regulation rate, wherein the difference between the first ratio and the second ratio is within a preset difference range;

The above embodiments of the present application provide two processes of determining a first temperature adjustment rate and a second temperature adjustment rate, wherein, compared to the first process of determining a temperature adjustment rate, the second process of determining a temperature adjustment rate can shorten the time period for the first indoor temperature and the second indoor temperature to reach the set temperature; compared with the second process of determining the temperature adjusting rate, the first process of determining the temperature adjusting rate can enable the overshoot amount of the first indoor temperature and the second indoor temperature to be smaller when the first indoor temperature and the second indoor temperature reach the set values, and enable the temperature rising or reducing process of the first room and the second room to be more stable.
