Fig. 1 is a schematic diagram of an implementation scenario of a method for controlling an air conditioner according to an embodiment of the present application. The implementation scene comprises a first room R1 and a second room R2, wherein the first room R1 is provided with a first air conditioner K1, the first air conditioner K1 can adjust a first indoor temperature T1 in the first room R1, the second room R2 is provided with a second air conditioner K2, the second air conditioner K2 can adjust a second indoor temperature T2 in the second room R2, and the first room R1 and the second room R2 can exchange heat through a channel P, and the channel P can be an opened door, an opened window, or an opened door and window. Under the condition that the first indoor temperature T1 is higher than the second indoor temperature T2, heat flows from the first room R1 to the second room R2 through the channel P, so that the first indoor temperature T1 has a decreasing trend, and the second indoor temperature T2 has an increasing trend; under the condition that the first indoor temperature T1 is lower than the second indoor temperature T2, heat flows from the second room R2 to the first room R1 through the channel P, so that the first indoor temperature T1 has a decreasing trend, and the second indoor temperature T2 has an increasing trend.

Whether the passage P is opened or not may be detected by the door and/or window opening state detecting means, for example, an in-place sensor may be installed on the door and/or window, and the opening state of the door and/or window may be determined using the detection signal of the in-place sensor to determine whether or not there is heat exchange between the first room R1 and the second room R2.

The method for controlling the air conditioner provided by the embodiment of the application is suitable for being applied to a scene with a large temperature difference between the first indoor temperature T1 of the first room R1 and the second indoor temperature T2 of the second room R2. For example, before the first room R1 and the second room R2 are switched from the state where there is no heat exchange to the state where there is heat exchange, the set temperatures required by the first room R1 (for example, the room where an infant is located) and the second room R2 (for example, the room where a young child is located) are different, and the first indoor temperature T1 and the second indoor temperature T2 of the first room R1 and the second room T2 reach the set temperatures respectively; in this way, after the first room R1 and the second room R2 are switched from the state where there is no heat exchange to the state where there is heat exchange, the temperature difference between the first indoor temperature T1 of the first room R1 and the second indoor temperature T2 of the second room R2 is large; after the heat exchange between the first room R1 and the second room R2, the set temperature shared by the first room R1 and the second room R2 needs to be balanced between the optimal temperatures of the members, and in this case, the first room R1 needs to be cooled and the second room R2 needs to be warmed.

After the heat exchange exists between the first room R1 and the second room R2, if the first air conditioner K1 and the second air conditioner K2 are stopped, the temperatures of the two rooms tend to be balanced under the condition of natural heat exchange, which obviously causes long time consumption; if the first air conditioner K1 and the second air conditioner K2 are used for cooling and heating according to a conventional control method, for example, proportional-integral-derivative (Proportion Integral Differential, PID) is adopted, when the temperature difference between the first room R1 and the second room R2 is large, the first air conditioner K1 and the second air conditioner K2 are both rapidly reduced, which is equivalent to rapid cooling or heating when the heat flow between the first room R1 and the second room R2 is maximum, so that the cooling influence of the heat flow between the first room R1 and the second room R2 on the first indoor temperature T1 and the heating influence on the second indoor temperature T2 are reduced to the greatest extent, and the energy consumption is high.

According to the method for controlling the air conditioner, the room temperature change rate (the cooling rate of the first room R1 and the heating rate of the second room R2) corresponding to the third temperature adjusting stage is smaller than the room temperature change rate corresponding to the second temperature adjusting stage, so that the first indoor temperature T1 of the first room R1 and the second indoor temperature T2 of the second room R2 can reach the set temperature (the set temperature shared by the first room R1 and the second room R2) more stably, the temperature change rate corresponding to the second temperature adjusting stage is maximum, and the time period required for the first indoor temperature T1 and the second indoor temperature T2 to reach the set temperature can be shortened; the temperature change rate of the first temperature adjusting stage is smaller than that of the second stage, so that the first room R1 and the second room R2 can maintain a higher temperature difference value, heat flow of the first room R1 and the second room R2 is fully utilized, and energy consumption is reduced. By setting different temperature adjusting stages, the balance between the reduction of the total energy consumption of the air conditioner and the rapid temperature adjustment can be achieved.

Fig. 2 is a schematic diagram of a method for controlling an air conditioner according to an embodiment of the present application. 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, for a first room and a second room with heat exchange, under the conditions of cooling the first room and heating the second room, obtaining a first temperature difference value between a first indoor temperature of the first room and a set temperature at the current moment and a second temperature difference value between the set temperature and a second indoor temperature of the second room.

In a home or office scenario, it is often necessary to balance the temperature of each room, i.e. to adjust the indoor temperature of each room to the same set temperature, to meet the comfort needs of each user.

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 and the second indoor temperature are both higher than the set temperature, and the first room and the second room are required to be cooled simultaneously at the moment; or the first indoor temperature and the second indoor temperature are both smaller than the set temperature, and the first room and the second room are required to be subjected to simultaneous temperature rising treatment at the moment; or, in the first indoor temperature and the second indoor temperature, one indoor temperature is greater than the set temperature, and the other indoor temperature is less than the set temperature, at this time, a heating process is required to be performed on one room, and a cooling process is required to be performed on the other room.

The method for controlling the air conditioner is applicable to situations that the first indoor temperature is higher than the set temperature, the second indoor temperature is lower than the set temperature, the first room is required to be cooled, and the second room is required to be heated.

In the embodiment of the present application, for convenience of explanation, the first temperature difference and the second temperature difference exist in the form of positive values, for example, the first indoor temperature may be subtracted from the set temperature to obtain the first temperature difference, and the second indoor temperature may be subtracted from the set temperature to obtain the second temperature difference.

Of course, the first temperature difference and the second temperature difference exist in the form of positive values, and only for convenience of explanation, in practical application, the first indoor temperature is generally subtracted from the set temperature to obtain the first temperature difference, the second indoor temperature is subtracted from the set temperature to obtain the second temperature difference, and then the signs of the first indoor temperature and the second indoor temperature are considered when calculating by using the first indoor temperature and the second indoor temperature.

S202, determining the current temperature regulating stage in the three temperature regulating stages according to the first temperature difference value and the second temperature difference value.

Before the step is executed, three temperature adjusting stages are firstly arranged, and the three temperature adjusting stages are a first temperature adjusting stage, a second temperature adjusting stage and a third temperature adjusting stage in sequence from the big temperature difference to the small temperature difference.

The three temperature adjusting stages comprise three temperature reducing stages corresponding to the first room and three temperature increasing stages corresponding to the second room. And the three cooling stages corresponding to the first room are not identical to the three heating stages corresponding to the second room, so as to adapt to the working conditions of the first room and the second room. The first temperature adjusting stage corresponds to a first temperature reducing stage of the first room and a first temperature increasing stage of the second room, the second temperature adjusting stage corresponds to a second temperature reducing stage of the first room and a second temperature increasing stage of the second room, and the third temperature adjusting stage corresponds to a third temperature reducing stage of the first room and a third temperature increasing stage of the second room.

Specifically, a section greater than the first temperature threshold may be determined as a first cooling stage corresponding to the first room, a section less than or equal to the first temperature threshold and greater than the second temperature threshold may be determined as a second cooling stage of the first room, and a section less than or equal to the second temperature threshold may be determined as a third cooling stage of the first room; the section larger than the third temperature threshold is determined as a first temperature rising stage corresponding to the second room, the section smaller than or equal to the third temperature threshold and larger than the fourth temperature threshold is determined as a second temperature rising stage of the second room, and the section smaller than the fourth temperature threshold is determined as a third temperature rising stage of the second room. The first temperature threshold, the second temperature threshold, the third temperature threshold and the fourth temperature threshold can be set before the air conditioner leaves the factory; and the air conditioner can also be manually debugged by a professional after leaving the factory.

Thus, determining the current tempering stage from among the three tempering stages based on the first temperature difference and the second temperature difference may include: determining the first temperature regulation stage as the current temperature regulation stage under the condition that the first temperature difference value is larger than a first temperature threshold value and the second temperature difference value is larger than a third temperature threshold value; determining the second temperature regulation stage as the current temperature regulation stage when the first temperature difference value is smaller than or equal to the first temperature threshold value, larger than the second temperature threshold value, and the second temperature difference value is smaller than or equal to the third temperature threshold value and larger than the fourth temperature threshold value; and determining the third temperature regulating stage as the current temperature regulating stage when the first temperature difference value is smaller than or equal to the second temperature threshold value and the second temperature difference value is smaller than or equal to the fourth temperature threshold value.

Of course, in the case where the current temperature adjustment stage is the first temperature adjustment stage, this is the first temperature reduction stage for the first room, and the case is the first temperature increase stage for the second room; in the case where the temperature adjustment phase is the second temperature adjustment phase or the third temperature adjustment phase, the specific meaning of the current temperature adjustment phase for the first room and the second room is similar, and will not be described in detail here.

After the first temperature adjustment stage is determined as the current temperature adjustment stage, the first temperature difference value of the first room is continuously reduced, the second temperature difference value of the second room is continuously reduced, the situation that the first temperature difference value is not greater than the first temperature threshold value and the second temperature difference value is greater than the third temperature threshold value can occur, or the situation that the first temperature difference value is greater than the first temperature threshold value and the second temperature difference value is not greater than the third temperature threshold value can occur, at this time, the first temperature adjustment stage is still determined as the current temperature adjustment stage until the first temperature difference value is greater than the second temperature threshold value and is less than or equal to the first temperature threshold value, the second temperature difference value is greater than the fourth temperature threshold value and is less than or equal to the third temperature threshold value, and then the second temperature adjustment stage is determined as the current temperature adjustment stage.

After the second temperature adjustment stage is determined as the current temperature adjustment stage, the first temperature difference value of the first room is continuously reduced, the second temperature difference value of the second room is continuously reduced, the situation that the first temperature difference value is smaller than or equal to the second temperature threshold value and the second temperature difference value is larger than the fourth temperature threshold value can occur, or the situation that the first temperature difference value is larger than the second temperature threshold value and the second temperature difference value is smaller than or equal to the fourth temperature threshold value can occur, at this time, the second temperature adjustment stage is determined as the current temperature adjustment stage until the first temperature difference value is smaller than or equal to the second temperature threshold value and the second temperature difference value is smaller than or equal to the fourth temperature threshold value, and then the third temperature adjustment stage is determined as the current temperature adjustment stage.

The current temperature regulating stage can be determined through the technical scheme.

S203, determining the current cooling rate of the first room and the current heating rate of the second room corresponding to the current temperature regulating stage according to the corresponding relation between the temperature regulating stage and the room temperature change rate.

The correspondence of the tempering stage to the rate of change of the room temperature is also set before the execution of the method. And, for the first room, the correspondence between the temperature adjustment stage and the room temperature change rate refers to the correspondence between the temperature reduction stage and the room temperature decrease rate; for the second room, the correspondence between the temperature-adjusting stage and the rate of change of the room temperature refers to the correspondence between the temperature-adjusting stage and the rate of rise of the room temperature.

The room temperature change rate corresponding to the second temperature adjusting stage is larger than that corresponding to the first temperature adjusting stage, and the room temperature change rate corresponding to the second temperature adjusting stage is larger than that corresponding to the third temperature adjusting stage. In the first room, the room temperature descending speed corresponding to the second cooling stage is larger than the room temperature descending speed corresponding to the first cooling stage, and the room temperature descending speed corresponding to the second cooling stage is larger than the room temperature descending speed corresponding to the third cooling stage; in the second room, the room temperature rising rate corresponding to the second temperature rising stage is greater than the room temperature rising rate corresponding to the first temperature rising stage, and the room temperature rising rate corresponding to the second temperature rising stage is greater than the room temperature rising rate corresponding to the third temperature rising stage.

The correspondence between the temperature adjustment stage and the room temperature change rate may be a correspondence between the temperature adjustment stage and a fixed room temperature change rate, or a correspondence between the temperature adjustment stage and an average room temperature change rate.

For example, the first temperature adjustment stage corresponds to a first temperature decrease rate of the first room and a second temperature increase rate of the second room, the second temperature adjustment stage corresponds to a second temperature decrease rate of the first room and a second temperature increase rate of the second room, and the first temperature decrease rate, the second temperature decrease rate, the first temperature increase rate, and the second temperature increase rate may all be fixed room temperature change rates; the third tempering stage corresponds to a third cooling rate of the first room and a third warming rate of the second room, which may be average room temperature change rates.

Through the mode, the current cooling rate of the first air conditioner and the current heating rate of the second air conditioner can be obtained.

S204, controlling a first air conditioner of a first room according to the current cooling rate, and controlling a second air conditioner of a second room according to the current heating rate.

The cooling rate of the first room has a corresponding relation with the refrigerating power of the first air conditioner, and the heating rate of the second room has a corresponding relation with the heating power of the second air conditioner. After the current cooling rate is obtained, the current refrigeration power corresponding to the current cooling rate can be obtained, and the first air conditioner is controlled according to the refrigeration power, for example, the larger the operation frequency of a compressor of the first air conditioner is, the larger the refrigeration power of the first air conditioner is, the higher the rotating speed of an indoor fan of the first air conditioner is, and the larger the refrigeration power of the first air conditioner is; after the current temperature rising rate is obtained, the current heating power corresponding to the current temperature rising rate can be obtained, and the second air conditioner is controlled according to the heating power, for example, the larger the running frequency of a compressor of the second air conditioner is, the larger the heating power of the second air conditioner is, the higher the rotating speed of an indoor fan of the second air conditioner is, and the heating power of the second air conditioner is.

When the current temperature adjustment stage is the third temperature adjustment stage, the first air conditioner and the second air conditioner can be controlled according to a control method (for example, a PID control method) in the prior art, at the moment, the first temperature difference value and the second temperature difference value are smaller, the difference value between the first indoor temperature and the second indoor temperature is smaller, the influence of heat flow of the two rooms on the temperatures of the two rooms is smaller, the excessive overshoot is not caused by adopting the existing control method, and the first indoor temperature and the second indoor temperature are relatively easy to stabilize at the set temperature.

Fig. 3 is a schematic diagram of a change in temperature difference between a first indoor temperature and a second indoor temperature according to an embodiment of the present application.

In fig. 3, the horizontal axis represents the time T axis, and the vertical axis represents the temperature T axis; the curve T1 is a first indoor temperature change curve, the curve T11 is a change curve of the first indoor temperature in a first temperature regulation stage, the curve T12 is a change curve of the first indoor temperature in a second temperature regulation stage, and the curve T13 is a corresponding change curve of the first indoor temperature in a third temperature regulation stage; curve T2 is a schematic diagram of the second indoor temperature, curve T21 is a change curve of the second indoor temperature in the first temperature adjustment stage, curve T22 is a change curve of the second indoor temperature in the second temperature adjustment stage, and curve T23 is a corresponding change curve of the second indoor temperature in the third temperature adjustment stage; t0 is a set temperature; the curve Δt is a change curve of a temperature difference between the first indoor temperature T1 and the second indoor temperature T2, the curve Δt1 is a change curve of a temperature difference between the first indoor temperature T11 and the second indoor temperature T21 in the first temperature adjustment stage, the curve Δt2 is a change curve of a temperature difference between the first indoor temperature T12 and the second indoor temperature T22 in the second temperature adjustment stage, and the curve Δt3 is a change curve of a temperature difference between the first indoor temperature T13 and the second indoor temperature T23 in the third temperature adjustment stage. Thus, the time integral value of the curve Δt in the figure corresponds to the total amount of heat flow in the first room and the second room. As can be seen in fig. 3, the integral value of the curve Δt1 with respect to time (the area enclosed by the curve Δt1 and the time T axis) is large, which is advantageous in that the flow between the first room and the second room is fully utilized to reduce the total energy consumption of the first air conditioner and the second air conditioner in the process of warming the first room and the second room.

In the foregoing implementation, the first temperature threshold value, the second temperature threshold value, the third temperature threshold value, and the fourth temperature threshold value are explained, and the first temperature threshold value and the third temperature threshold value may also be determined in the manner as shown in fig. 4.

Referring to fig. 4, the determining process of the three temperature adjustment stages may include:

s401, when the method is executed for the first time, a third temperature difference value between the third indoor temperature of the first room and the set temperature and a fourth temperature difference value between the set temperature and the fourth indoor temperature of the second room are obtained.

After the first room and the second room are switched from the state without heat exchange to the state with heat exchange, the method is executed for the first time; or, after the set temperature is changed, it is the case that the present method is performed for the first time.

That is, when the present method is first executed, three temperature adjustment stages (three temperature adjustment stages including three temperature reduction stages of the first room and three temperature increase stages of the second room) are determined according to the third indoor temperature of the first room, the fourth set temperature of the second room, and the set temperature at that time.

After the three tempering phases are determined, S201, S202, S203 and S204 in the previous embodiment are performed again.

Similarly, for convenience of explanation, the third temperature difference and the fourth temperature difference are still positive, the third temperature difference is obtained by subtracting the set temperature from the third indoor temperature, and the fourth temperature difference is obtained by subtracting the fourth indoor temperature from the set temperature. In practical applications, the third temperature difference and the fourth temperature difference may be signed.

S402, obtaining a first product of the third temperature difference value and the set ratio, and a second product of the fourth temperature difference value and the set ratio.

The set ratio here may be greater than or equal to 1/2, for example, the set ratio may be 1/2, 2/3, 3/4 or 4/5.

If the set ratio is too large, the first indoor temperature and the second indoor temperature can be caused to reach the set temperature for too long; if the set ratio is too small, the power consumption of the first air conditioner and the second air conditioner may be increased. Those skilled in the art can determine the setting ratio according to the actual requirement according to the setting ratio, and the detailed description is omitted here.

S403, determining a first temperature threshold and a third temperature threshold according to the magnitude relation of the first product and the second product.

If the first product is less than the second product, the first product may be determined to be a first temperature threshold; if the first product is greater than or equal to the second product, the second product may be determined to be a third temperature threshold.

Specifically, determining the first temperature threshold and the third temperature threshold according to the magnitude relation of the first product and the second product includes: in the case that the first product is less than the second product, determining the first product as a first temperature threshold; obtaining a first threshold difference between the first temperature threshold and the second temperature threshold; obtaining a second threshold difference value corresponding to the first threshold difference value; and determining the sum of the difference values of the fourth temperature threshold and the second threshold as a third temperature threshold.

Alternatively, determining the first temperature threshold and the third temperature threshold based on the magnitude relation of the first product and the second product may include: determining the second product as a third temperature threshold in the event that the first product is greater than or equal to the second product; obtaining a second threshold difference value between the third temperature threshold and the fourth temperature threshold; obtaining a first threshold difference value corresponding to the second threshold difference value; and determining the sum of the difference values of the second temperature threshold and the first threshold as the first temperature threshold.

The second temperature threshold and the fourth temperature threshold are both known values. The second temperature threshold is related to the stability of the first air conditioner when the first air conditioner adjusts the temperature of the first room, the stronger the stability of the first air conditioner is, the smaller the second temperature threshold is, the weaker the stability of the first air conditioner is, and the larger the second temperature threshold is needed to be; the fourth temperature threshold may be related to the stability of the second air conditioner when the second air conditioner adjusts the temperature of the second room, where the higher the stability of the second air conditioner is, the smaller the fourth temperature threshold may be, the weaker the stability of the second air conditioner is, and the larger the fourth temperature threshold is required.

The stabilizing capability of the first air conditioner when the first air conditioner adjusts the temperature of the first room can be used for reaching the set temperature for the first time, and the time period required by the difference value between the first indoor temperature and the set temperature to be stabilized in the dead zone range is longer, the stabilizing capability of the first air conditioner is weaker, and the time period is shorter, the stabilizing capability of the first air conditioner is stronger.

The stabilizing capability of the second air conditioner when the second air conditioner adjusts the temperature of the second room can be used for reaching the set temperature for the first time, until the time required by the difference value between the second indoor temperature and the set temperature to be stabilized in the dead zone range is longer, the stabilizing capability of the second air conditioner is weaker, and the time is shorter, the stabilizing capability of the second air conditioner is stronger.

The correspondence between the first threshold difference and the second threshold difference may include: under the condition that heat exchange does not exist in the first room and the second room, controlling the first air conditioner to operate for a first set duration according to the set refrigeration power, and determining the cooling down temperature of the first room as a first threshold difference value; and controlling the second air conditioner to operate for a first set duration according to the set customized heating power, and determining the rising temperature of the second room as a second threshold difference value.

The longer the duration of the first set duration is, the longer the duration of the first room for rapid cooling is, the shorter the duration of the first room from the initial temperature to the set temperature is, and the shorter the duration of the second room from the initial temperature to the set temperature is; the shorter the first set time length is, the shorter the time length of the first room for quickly cooling is, the longer the time length of the first room from the initial temperature to the set temperature is, and the longer the time length of the second room from the initial temperature to the set temperature is. The person skilled in the art can adaptively adjust the first set time period according to the expected time period when the first room reaches the set temperature from the initial temperature and the expected time period when the second room reaches the set temperature from the initial temperature, which is not particularly limited herein.

The set refrigeration power may be the rated refrigeration power of the first air conditioner, and the set heating power may be the rated heating power of the second air conditioner; or, the ratio of the set cooling power to the rated cooling power of the first air conditioner is the same as the ratio of the set heating power to the rated heating power of the second air conditioner. The ratio may be 5/6, 4/5, 3/4, etc.

According to the mode, the first temperature threshold and the third temperature threshold can be determined.

S404, dividing the cooling process of the first room into three temperature regulation stages according to the first temperature threshold value and the second temperature threshold value.

S405, dividing the temperature rising process of the second room into three temperature regulating stages according to the third temperature threshold value and the fourth temperature threshold value.

S405 and S404 are not distinguished from each other.

The first temperature threshold determined according to the scheme is more in accordance with the refrigerating working condition of the first room, and the third temperature threshold determined according to the scheme is more in accordance with the heating working condition of the second room, so that three temperature regulation stages in accordance with the working condition of the first room and the working condition of the second room are distinguished.

The process is a process of dividing three temperature regulation stages, and according to the dividing rule, the time when the temperature of the first room reaches the first temperature threshold and the time when the temperature of the second room reaches the third temperature threshold are the same; the time when the temperature of the first room reaches the second temperature threshold is the same as the time when the temperature of the second room reaches the fourth temperature threshold. In a specific application, the tempering stage is still determined as described above on the basis of the first temperature difference and the second temperature difference.

The following describes in detail the room temperature change rates corresponding to the three tempering stages:

in the third temperature adjustment stage, the first air conditioner and the second air conditioner can both adopt the existing control method with the deviation elimination function, and the room temperature falling rate (third temperature reduction rate) of the first room and the room temperature rising rate (third temperature rising rate) of the second room can be controlled by the corresponding control methods.

In the second temperature adjustment stage, the room temperature falling rate (second cooling rate) of the first room corresponds to the set refrigeration power of the first air conditioner; the rate of rise in the room temperature of the second room (second rate of rise in temperature) corresponds to the set heating power of the second air conditioner. The set refrigeration power can be 5/6, 4/5 or 3/4 of the rated refrigeration power of the first air conditioner, and the set heating power can be 5/6, 4/5 or 3/4 of the rated heating power of the second air conditioner; the ratio of the set cooling power to the rated cooling power of the first air conditioner may be equal to the ratio of the set heating power to the rated heating power of the second air conditioner.

In the first temperature adjusting stage, the corresponding relation between the temperature adjusting stage and the room temperature change rate can be determined by the following modes: obtaining a temperature reduction value from the third temperature difference value to the first temperature threshold value; determining a first cooling rate of the first room corresponding to the first temperature adjusting stage according to the quotient of the temperature reduction value and the second set time length; obtaining a temperature rise value from the fourth temperature difference value to the third temperature threshold value; and determining a first temperature rising rate of the second room corresponding to the first temperature regulating stage according to the quotient of the temperature rising value and the second set time period. The second set period of time is typically greater than the first set period of time described above, and may be 2 times, 2.5 times, 3 times, or more than the first set period of time.

According to the method, the corresponding relation between the temperature regulating stage and the room temperature change rate can be obtained, then the current temperature regulating stage can be determined according to the first temperature difference value and the second temperature difference value, and the first air conditioner and the second air conditioner can be controlled according to the current temperature regulating stage.
