In the process of implementing the embodiment of the present application, it is found that at least the following problems exist in the related art:
the larger the temperature difference is, the larger the cooling power or heating power is, the longer the indoor temperature can be shortened to a certain extent to reach the set temperature, but a door and window is usually arranged between two rooms in a household, and when the door and window are opened, heat exchange exists between the two rooms, heat flows from the room with higher temperature to the room with lower temperature, and the larger the temperature difference is, the larger the heat flows. Because the volumes of the two rooms and the parameters of the air conditioners of the two rooms are different, in the process of respectively controlling the air conditioners of the two rooms by adopting the traditional control method, the two rooms are independently heated or cooled, so that the heat flow between the two rooms is uneven, the stability of the heating process or the cooling process of the two rooms is poor, and finally the stability of the indoor temperature of the two rooms when the indoor temperature of the two rooms reaches the set temperature is poor. Therefore, under the condition that two rooms with heat exchange are heated or cooled at the same time, the prior art cannot achieve both the temperature regulation rate and the stability when the temperatures of the two rooms reach the set temperature.

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.
In addition, in other application scenarios, for example, in an office application scenario, the first room and the second room may be two rooms that communicate through a corridor, or two rooms that are separated by a partition, such first room and the second room may have a higher heat mobility.
The embodiment of the application provides a method for controlling an air conditioner, which is used for carrying out sectional treatment on the heating process or the cooling process of a first room and a second room, carrying out rapid heating or rapid cooling on the first room and the second room by utilizing a first stage, carrying out stable heating on the first room and the second room by utilizing a second stage, reducing the adverse effect of the heat flow of the two rooms on the stability of the heating process or the cooling process, and eliminating or relieving the temperature influence of hysteresis generated by the refrigeration power or the heating power of the air conditioner in the first stage, and carrying out stable treatment on the heating process or the cooling process of the two rooms so as to improve the stability when the temperature of the two rooms reaches the set temperature. In this way, the temperature adjustment rate and the stability when the set temperature is reached are simultaneously considered in the process of temperature adjustment of two rooms with heat exchange.
In addition, in the first stage, the larger the heating rate or the cooling rate of the second room is, the more advantageous is to further improve the stability to be maintained in the second stage, and finally, the more advantageous is to improve the temperature adjustment rate and the stability when the set temperature is reached.
Fig. 2 is a flow chart 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, in the case of simultaneously heating or cooling the first room and the second room having heat exchange, a first temperature difference between the set temperature and the first indoor temperature of the first room and a second temperature difference between the set temperature and the second indoor temperature of the second room are obtained.
In a home or office setting, it is often desirable to balance the temperature of each room, i.e., to adjust the indoor temperature of each room to the same set temperature, to improve user comfort. The set temperature here, i.e. the set temperature matching the user's comfort, may be a set temperature matching most user's comfort.
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 suitable for the condition that the first indoor temperature and the second indoor temperature are simultaneously higher or lower than the set temperature.
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, in the case that the first room and the second room are heated at the same time, 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; in the case where the first room and the second room are cooled simultaneously, the set temperature may be subtracted from the first indoor temperature to obtain a first temperature difference, and the set temperature may be subtracted from the second indoor temperature to obtain a second temperature difference.
Of course, the first temperature difference and the second temperature difference exist in positive values, and for convenience of illustration only, in practical application, the first indoor temperature is generally subtracted from the set temperature to obtain the first temperature difference, and the second indoor temperature is subtracted from the set temperature to obtain the second temperature difference.
For convenience of description, the first temperature difference is smaller than the second temperature difference in the examples of the present application, and in the case that the first room and the second room are simultaneously warmed up, the first indoor temperature is higher than the second indoor temperature; in the case where the first room and the second room are cooled simultaneously, the first indoor temperature is lower than the second indoor temperature.
S202, obtaining an indoor temperature difference value between the first indoor temperature and the second indoor temperature under the condition that the first temperature difference value is larger than a temperature threshold value.
The temperature threshold is described in detail herein:
the first temperature difference may be used to represent a degree of deviation of the first indoor temperature from the set temperature, and the temperature threshold may be used to classify the degree of deviation of the first indoor temperature from the set temperature. For example, in the case where the first temperature difference is greater than the temperature threshold value, it may be indicated that the first indoor temperature is deviated from the set temperature to a high degree, and in the case where the first temperature difference is less than or equal to the temperature threshold value, it may be indicated that the first indoor temperature is deviated from the set temperature to a low degree.
The temperature threshold may be a temperature value set when the air conditioner leaves the factory, or a temperature threshold adjusted by a professional after the air conditioner leaves the factory. The temperature threshold here may be 2 ℃, 3 ℃ or 4 ℃.
S203, if the indoor temperature difference value is greater than or equal to the set temperature difference value, controlling a first air conditioner of a first room according to a first control strategy, and controlling a second air conditioner of a second room according to a second control strategy.
First, the set temperature difference will be described in detail:
the set temperature difference value is used for dividing a rapid temperature adjustment (temperature rising or temperature reducing) stage and a stable temperature adjustment stage. For ease of description, the fast ramp phase is defined herein as the first phase and the steady ramp phase is defined herein as the second phase.
In the first phase, it is necessary to adjust the first indoor temperature of the first room and the second indoor temperature of the second room as quickly as possible; in the second phase, it is desirable to adjust the first indoor temperature and the second indoor temperature of the first room as stably as possible to reduce the adverse effect of the heat flow of the two rooms on the rate of temperature change and to alleviate or eliminate the hysteresis temperature fluctuation caused by the first phase.
The set temperature can be obtained experimentally: if the time required for the first indoor temperature and the second indoor temperature to reach the set temperature is too long, the set temperature difference value can be reduced; if the fluctuation in the first indoor temperature and the second indoor temperature reaches the set temperature is excessive, the set temperature difference value can be increased; finally, the time length required for the first indoor temperature and the second indoor temperature to reach the set temperature and the fluctuation of the first indoor temperature and the second indoor temperature to reach the set temperature are both in accordance with the product requirement.
In addition, the set temperature difference may also be determined by: a set temperature difference value that is positively correlated to the temperature threshold is determined. The correlation coefficient of the positive correlation can be obtained by the above test, for example, if the time period required for the first indoor temperature and the second indoor temperature to reach the set temperature is too long, the correlation coefficient of the positive correlation can be reduced; if the fluctuation in the first indoor temperature and the second indoor temperature reaches the set temperature is excessive, the correlation coefficient of the positive correlation may be increased.

On the one hand, the first temperature difference value can be reduced, the indoor temperature difference value can also be reduced, and the larger the first indoor temperature difference value before adjustment is, the larger the reduction of the first indoor temperature difference value after the adjustment in the first stage is; the larger the indoor temperature difference before adjustment, the larger the difference between the change rate of the second indoor temperature and the change rate of the first indoor temperature in the adjustment process of the first stage, and the larger the reduction of the indoor temperature difference after adjustment.

Or the corresponding relation between the temperature difference and the temperature regulating power exists in the form of a control algorithm, wherein the temperature difference is input quantity, and the temperature regulating power is output quantity in the control algorithm. Thus, after the first temperature difference value and the second temperature difference value are obtained, the first temperature difference value is input into the control algorithm, so that the first temperature adjusting power corresponding to the first temperature difference value output by the control algorithm can be obtained, and the second temperature difference value is input into the control algorithm, so that the second temperature adjusting power corresponding to the second temperature difference value output by the control algorithm can be obtained.

In addition, according to the third temperature difference value between the set temperature difference value and the indoor temperature difference value, adjusting the temperature adjusting power of the first air conditioner of the first room and the second air conditioner of the second room 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 third 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 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 third temperature difference value, the temperature adjustment powers of the first air conditioner and the second air conditioner may be positively correlated with the first temperature difference value.
