The method for controlling the air conditioner may be performed by a controller of the air conditioner, or by a control panel or a remote controller communicatively connected to the air conditioner, or by a server of the smart home system. 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 connection with fig. 2, the method for controlling an air conditioner includes:

s201, when the temperature of the first room and the second room having heat exchange are raised or lowered simultaneously, 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 exchange heat through an opened door and/or window, or through a 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 each adjusted to the set temperature, and the set temperature is a common set temperature.

The case where neither the first indoor temperature of the first room nor the second indoor temperature of the second room reaches 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 the moment, the first room is required to be cooled, the second room is required 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 the moment, the first room is required to be heated, and the second room is required to be cooled; the first indoor temperature of the first room and the second indoor temperature of the second room are both larger than the set temperature, and at the moment, the first room and the second room are required to be cooled; the first indoor temperature of the first room and the second indoor temperature of the second room are both smaller than the set temperature, and at this time, the first room and the second room need to be subjected to temperature raising treatment.

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

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

The set temperature may be set by a user, or may be a temperature that is suitable for human comfort or health by using big data, artificial intelligence, or the like. The mode of obtaining the set temperature in the embodiment of the present application is not particularly limited, and a person skilled in the art may select a suitable prior art to obtain the set temperature according to actual situations.

S202, 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.

S203, 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.

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

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

The temperature difference between 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 when the method for controlling the air conditioner is performed for the first time.

The temperature adjusting power of the first air conditioner and the second air conditioner refers to the first temperature adjusting power of the first air conditioner and the second temperature adjusting power of the second air conditioner; in a scene that a first room and a second room are heated at the same time, the first temperature-adjusting power of the first air conditioner refers to the heating power of the first air conditioner, and the second temperature-adjusting power of the second air conditioner refers to the heating power of the second air conditioner; in a scenario where 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 regulating power of the air conditioner are the frequency of the air conditioner compressor and the rotational speed of the indoor fan, for example, the higher the frequency of the air conditioner compressor, the higher the temperature regulating power of the air conditioner; the higher the rotation speed of the indoor fan, the higher the temperature adjusting power of the air conditioner.

Further, if the absolute value of the first temperature difference is smaller than the absolute value of the second temperature difference, the power difference of the first temperature adjustment power and the second temperature adjustment power is positively correlated with the set temperature difference if the first temperature adjustment power is larger than the second temperature adjustment power; if the first temperature regulating power is smaller than the second temperature regulating power, the second temperature regulating power is inversely related to the power difference value of the first temperature regulating power;

If the absolute value of the first temperature difference value is larger than the absolute value of the second temperature difference value, the power difference value of the first temperature adjustment power and the second temperature adjustment power is inversely related to the set temperature difference value; if the first temperature regulating power is smaller than the second temperature regulating power, the second temperature regulating power is positively correlated with the power difference value of the first temperature regulating power.

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

Under the condition that the first air conditioner and the second air conditioner are used for refrigerating simultaneously, if the first temperature regulating power is larger than the second temperature regulating power, the larger temperature difference value can enable the cold quantity (reverse direction of heat flow) of the first room to flow to the second room more, so that the heating rate of the first room and the second room is improved as a whole; if the first temperature regulated power is less than the second temperature regulated power, the smaller temperature difference may cause less heat from the first room to flow to the second room, reducing the load on 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 divided into low-grade temperature adjusting power, middle-grade temperature adjusting power and high-grade temperature adjusting power, wherein the low-grade temperature adjusting power is smaller than the middle-grade temperature adjusting power, and the middle-grade temperature adjusting power is smaller than the high-grade 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.

Alternatively, the first temperature adjustment power is determined based on the first temperature difference, and the second temperature adjustment power is determined based on the second temperature difference. In this case, adjusting the temperature adjustment power of the first air conditioner of the first room and the second air conditioner of the second room according to the fourth temperature difference between the set temperature difference and the third temperature difference may include: determining a first temperature regulating power corresponding to the first temperature difference value according to the corresponding relation between the first temperature difference value and the temperature regulating power; determining a second temperature regulating power corresponding to the second temperature difference value according to the corresponding relation between the second temperature difference value and the temperature regulating power; adjusting the first temperature regulating power and/or the second temperature regulating power according to the fourth temperature difference value; 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 correspondence between the temperature differences and the temperature adjusting powers can be obtained through limited tests, for example, different temperature adjusting powers are set for the air conditioner in sequence for one temperature difference, when the duration of eliminating the temperature difference accords with the expectation, the temperature adjusting power set at the moment is determined to be the temperature adjusting power corresponding to the one temperature difference, in this way, the temperature adjusting power corresponding to each temperature difference is determined, the correspondence between the temperature difference and the temperature adjusting power is stored in a database in a one-to-one correspondence manner, and after the first temperature difference is obtained, the first temperature adjusting power corresponding to the first temperature difference can be obtained by inquiring the database; after the second temperature regulating power is obtained, the second temperature regulating power corresponding to the second temperature difference value can be obtained by inquiring a database.

Alternatively, the correspondence between the temperature difference and the temperature adjustment power may be realized by a controller having a deviation elimination function, such as a proportional-integral-derivative (Proportion Integral Differential, PID) controller or a linear quadratic regulator (linear quadratic regulator). Inputting the first temperature difference value into a controller with a deviation elimination function, and obtaining a first temperature adjustment power corresponding to the first temperature difference value; and inputting the second temperature difference value into a controller with a deviation elimination function, so as to obtain second temperature regulating power corresponding to the second temperature deviation.

The adjusting the temperature adjusting power of the first air conditioner of the first room and the second air conditioner of the second room comprises: 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, wherein the first temperature adjusting power of the first air conditioner is unchanged; or, the first temperature adjusting power of the first air conditioner and the second temperature adjusting power of the second air conditioner are adjusted simultaneously.

The following conditions are used for adjusting the first temperature adjusting power of the first air conditioner and/or the second temperature adjusting power of the second air conditioner: under the condition that the temperature of the first room and the second room is increased at the same time, if the first indoor temperature is higher than the second indoor temperature and the absolute value of the third temperature difference value is higher than the absolute value of the set temperature difference value, the first temperature adjusting power is reduced and/or the second temperature adjusting power is increased; if the first indoor temperature is greater than the second 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 regulating power is required to be increased and/or the second temperature regulating power is required to be reduced;

under the condition that the first room and the second room are cooled simultaneously, if the first indoor temperature is higher than the second indoor temperature and the absolute value of the third temperature difference value is higher than the absolute value of the set temperature difference value, the first temperature regulating power is increased and/or the second temperature regulating power is reduced; if the first indoor temperature is greater than the second 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 regulating power is reduced and/or the second temperature regulating power is increased.

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

The first temperature adjusting power and the second temperature adjusting power are adjusted in the mode, so that the fourth temperature difference value is beneficial to be close to zero, namely, the third temperature difference value between the first indoor temperature and the second indoor temperature is kept unchanged in the process of simultaneously heating or cooling the first room and the second room.

Fig. 3 is a schematic diagram of a process of adjusting a first temperature adjustment power and a second temperature adjustment power according to an embodiment of the present application. Referring to fig. 3, adjusting the first temperature adjustment power and the second temperature adjustment power according to the fourth temperature difference value includes:

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

S302, under the condition that the first temperature regulating power needs to be improved, the adjusted first temperature regulating power is determined according to the sum of the first temperature regulating 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 differential result is directly added to determine the first temperature adjustment power after temperature adjustment; alternatively, the sum of the first temperature adjustment power and the absolute value weighted sum of the differential results is determined as the adjusted first temperature adjustment power.

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

For example, a difference of the first temperature adjustment power and the absolute value of the differential result is determined as the first temperature adjustment power after temperature adjustment; alternatively, a difference of the first temperature adjustment power and the absolute value weighted subtraction of the differential result is determined as the adjusted first temperature adjustment power.

S304, under the condition that the second temperature regulating power needs to be improved, determining the adjusted second temperature regulating power according to the sum of the second temperature regulating 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 differential result is directly added to determine the second temperature adjustment power after temperature adjustment; alternatively, the sum of the second temperature adjustment power and the absolute value weighted sum of the differential results is determined as the adjusted second temperature adjustment power.

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

For example, a difference of the second temperature adjustment power directly subtracted from the absolute value of the differential result is determined as the second temperature adjustment power after temperature adjustment; alternatively, the difference of the second temperature adjustment power and the absolute value weighted subtraction of the differential result is determined as the adjusted second temperature adjustment power.

By adopting the technical scheme, the adjustment of the first temperature adjusting power and the second temperature adjusting power can be realized.

In addition, adjusting the temperature adjusting power of the first air conditioner of the first room and the second air conditioner of the second room according to the fourth temperature difference value of the set temperature difference value and the third temperature difference value may further include: and adjusting the temperature adjusting power of the first air conditioner and the second air conditioner according to the first temperature difference value and/or the second temperature difference value and the fourth temperature difference value, wherein the temperature adjusting power of the first air conditioner and the temperature adjusting power of the second air conditioner are positively correlated with the absolute value of the first temperature difference value and/or the second temperature difference value.

For example, in the case of adjusting the temperature adjustment powers of the first air conditioner and the second air conditioner according to the first temperature difference value and the fourth temperature difference value, the temperature adjustment powers of the first air conditioner and the second air conditioner may be positively correlated with the absolute values of the first temperature difference values.

In the case of adjusting the temperature adjustment powers of the first air conditioner and the second air conditioner according to the second temperature difference value and the fourth temperature difference value, the temperature adjustment powers of the first air conditioner and the second air conditioner may be positively correlated with the absolute value of the second temperature difference value.

Under the condition that the temperature regulating power of the first air conditioner and the second air conditioner is regulated according to the first temperature difference value and the second temperature difference value, the average temperature value of the absolute value of the first temperature difference value and the absolute value of the second temperature difference value can be obtained first, and then the temperature regulating power of the first air conditioner and the temperature regulating power of the second air conditioner are positively correlated with the average temperature value.

The method for controlling the air conditioner may be performed by a controller of the air conditioner, or by a control panel or a remote controller communicatively connected to the air conditioner, or by a server of the smart home system. 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 connection with fig. 4, the method for controlling an air conditioner includes:

s401, when the temperature of the first room and the second room having heat exchange are raised or lowered simultaneously, 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, 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.

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

S405, determining a first temperature regulating rate positively correlated with the first temperature difference and a second temperature regulating rate positively correlated with the second temperature difference 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, so that the difference value of the first ratio of the first temperature difference to the first temperature regulating rate and the second ratio of the second temperature difference to the second temperature regulating rate is in a preset difference range.

The first tempering rate refers to a rate at which the first indoor temperature of the first room increases or decreases, and the second tempering rate refers to a rate at which the second indoor temperature of the second room increases or decreases.

The first ratio of the first temperature difference to the first temperature adjustment rate can reflect the time period required for the first indoor temperature of the first room to reach the set temperature under the adjustment effect of the first air conditioner; the second ratio of the second temperature difference to the second temperature adjustment rate may reflect a time period required for the second indoor temperature of the second room to reach the set temperature under the adjustment of the second air conditioner; the difference between the first ratio and the second ratio is within a preset difference range, and may represent a duration of time required for the first indoor temperature of the first room to reach the set temperature, which is substantially the same as a duration of time required for the second indoor temperature of the second room to reach the set temperature.

The larger the preset difference range is, the more easily the fluctuation of the indoor temperatures of the first room and the second room around the set temperature is caused, and particularly, the fluctuation of the indoor temperature around the set temperature is larger in a room in which the indoor temperature reaches the set temperature first. The preset difference range is not particularly 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 indoor temperature fluctuation.

The first ratio and the second ratio reflect the time period required for adjusting the indoor temperature to the set temperature, the refrigerating power or the heating power of the air conditioner is limited, and the time period for adjusting the indoor temperature to the set temperature cannot be too short, namely, the first ratio and the second ratio cannot be too small, namely, the first temperature adjusting rate is in the temperature adjusting capacity range of the first air conditioner to the first room, and the second temperature adjusting rate is in the temperature adjusting capacity range of the second air conditioner to the second room. In general, the larger the first temperature adjustment power of the first air conditioner is, the larger the upper limit value of the first temperature adjustment rate is; the smaller the first temperature regulating power of the first air conditioner is, the smaller the upper limit value of the first temperature regulating rate is; the larger the volume of the first room, the smaller the upper limit value of the first temperature adjustment rate, and the smaller the volume of the first room, the larger the upper limit value of the first temperature adjustment rate; the larger the second temperature regulating power of the second air conditioner is, the larger the upper limit value of the second temperature regulating rate is; the smaller the second temperature regulating power of the second air conditioner is, the smaller the upper limit value of the second temperature regulating rate 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 temperature adjustment rate that is positively correlated to the first temperature difference and a second temperature adjustment rate that is positively correlated to the second temperature difference comprises:

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

Alternatively, determining a first temperature adjustment rate that is positively correlated to the first temperature difference and a second temperature adjustment rate that is positively correlated to the second temperature difference includes:

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