At present, air conditioners can be installed in different rooms of a family, the air conditioners can be multi-split air conditioners and split air conditioners, and each air conditioner can adjust the temperature of the room where the air conditioner is located. In the process of adjusting the temperature in the home, a set temperature may be set, a room having an indoor temperature higher than the set temperature is determined as a cooling room, and if an air conditioner in the cooling room is in a heating mode, an operation mode of the air conditioner in the cooling room is switched to a cooling mode, so that the temperatures of a plurality of rooms in the home may be all adjusted to a target temperature.
For the air conditioner of each room, a controller with a function of eliminating deviation is adopted for control, namely, a temperature difference value between the indoor temperature and the set temperature is firstly determined, then the cooling power or the heating power of the air conditioner is determined according to the temperature difference value, and the larger the temperature difference value is, the larger the cooling power or the heating power is.
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:
there is usually a window between two rooms in a home, and in case of the window being opened, there is heat exchange between the two rooms, heat flows from the room having a higher temperature to the room having a lower temperature, and the greater the difference between the temperatures of the two rooms, the greater the heat flow. The air conditioners of the two rooms are respectively controlled by adopting a traditional control method, and under the condition that the two rooms are heated, the indoor temperature of the room with higher temperature reaches the set temperature firstly; in the case where both rooms are at a reduced temperature, the indoor temperature of the room having a lower temperature reaches the set temperature first.
Before the indoor temperature in a room does not reach the set temperature, the operating power of the air conditioner corresponds to the temperature difference value between the indoor temperature and the set temperature of the room, and the heat flow of the room and the other room; when the indoor temperature of a first room reaches a set temperature, the indoor temperature of the first room fluctuates around the set temperature, at the moment, the operating power of an air conditioner in the first room corresponds to the heat flow between the two rooms, and then along with the change of the indoor temperature of the second room, the temperature difference between the two rooms is reduced, the heat flow between the two rooms is reduced, and further the fluctuation of the indoor temperature of the first room is aggravated; in addition, when the indoor temperature of the second room reaches the set temperature, the operation power of the air conditioner in the second room changes from corresponding to the temperature difference (the temperature difference between the indoor temperature of the second room and the set temperature) and the heat flow (the heat flow of the two rooms) to corresponding to the temperature difference, and the temperature of the room lags behind the operation power of the air conditioner relatively, so that the fluctuation of the indoor temperature of the second room in the vicinity of the set temperature is relatively large.

Fig. 2 is a schematic diagram of a method for controlling an air conditioner according to an embodiment of the present disclosure. The method for controlling the air conditioner may be performed by a controller of the air conditioner, or a control panel or a remote controller communicatively connected to the air conditioner, or 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.
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.
In a home, it is generally required to balance the temperatures of the respective rooms, that is, to adjust the indoor temperatures of the respective rooms to the same set temperature, so as to improve the user comfort.
The case where neither the first indoor temperature of the first room nor the second indoor temperature of the second room has reached the set temperature may include: the first indoor temperature and the second indoor temperature are both greater than the set temperature, and the first room and the second room need to be cooled simultaneously; or, both the first indoor temperature and the second indoor temperature are lower than the set temperature, and at this time, the first room and the second room need to be subjected to simultaneous heating treatment; 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, and at this time, it is necessary to perform a temperature raising process on one room and a temperature lowering process on the other room.
The method for controlling the air conditioner is suitable for the situation that the first indoor temperature and the second indoor temperature are greater than or less than the set temperature at the same time.
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.
In a specific application, the first room temperature may be subtracted from the set temperature to obtain a first temperature difference, and the second room temperature may be subtracted from the set temperature to obtain a second temperature difference.
S203, determining a first temperature adjusting rate positively correlated with the first temperature difference value and a second temperature adjusting rate positively correlated with the second temperature difference value.
And enabling the difference value of the ratio of the first temperature difference value to the first ratio of the first temperature adjusting rate to the second temperature difference value to the second ratio of the second temperature adjusting rate to be within the preset difference range.
The first temperature adjustment rate here refers to a rate of change of a first indoor temperature of the first room under the adjustment action of the first air conditioner; and a second temperature adjusting rate, which is a rate of change of a second indoor temperature of the second room by the adjusting action of the second air conditioner. Under the condition that the first indoor temperature and the second indoor temperature are both lower than the set temperature, the first temperature regulation rate and the second temperature regulation rate are both heating rates; and under the condition that the first indoor temperature and the second indoor temperature are both greater than the set temperature, the first temperature regulation rate and the second temperature regulation rate are both cooling rates.
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.
The first ratio and the second ratio reflect the time length required for adjusting the indoor temperature to the set temperature, the cooling power or the heating power of the air conditioner is limited, and the time length for adjusting the indoor temperature to the set temperature is not too short, namely, the first ratio and the second ratio cannot be too small, namely, the first temperature adjusting rate is within the temperature adjusting capacity range of the first air conditioner to the first room, and the second temperature adjusting rate is within the temperature adjusting capacity range of the second air conditioner to the second room. In general, the higher the temperature regulation power (cooling power or heating power) of the first air conditioner is, the higher the upper limit value of the first temperature regulation rate is; the lower the temperature adjusting power (cooling power or heating power) of the first air conditioner is, the lower the upper limit value of the first temperature adjusting rate 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 temperature adjusting power (cooling power or heating power) of the second air conditioner is, the larger the upper limit value of the second temperature adjusting rate is; the lower the temperature adjusting power (cooling power or heating power) of the second air conditioner is, the lower the upper limit value of the second temperature adjusting 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.
Specifically, the first temperature adjustment rate or the second temperature adjustment rate is a desired rate (i.e., the time period herein may be a desired time period), and may be an average temperature adjustment rate of the air conditioner to the room according to the existing temperature control method of the independent room (i.e., the first ratio or the second ratio is an average time period required for eliminating a certain temperature difference).
Optionally, determining a first temperature adjustment rate positively correlated to the first temperature difference and a second temperature adjustment rate positively correlated to the second temperature difference, so that a difference between a first ratio of the first temperature difference to the first temperature rate and a difference between a second ratio of the second temperature difference to the second temperature adjustment rate is within a preset difference range, including:
determining a temperature difference value with a large absolute value from the first temperature difference value and the second temperature difference value; determining the temperature regulation rate corresponding to the temperature difference value with the smaller absolute value in the first temperature difference value and the second temperature difference value according to the ratio of the temperature difference value with the larger absolute value to the temperature regulation rate corresponding to the temperature difference value; respectively controlling the corresponding air conditioners according to the two temperature adjusting rates;
alternatively, the first and second electrodes may be,
determining a temperature difference value with a small absolute value from the first temperature difference value and the second temperature difference value; determining the temperature regulation rate corresponding to the temperature difference value with the larger absolute value in the first temperature difference value and the second temperature difference value according to the ratio of the temperature difference value with the smaller absolute value to the temperature regulation rate corresponding to the temperature difference value; and respectively controlling the corresponding air conditioners according to the two temperature regulation rates.
And determining the temperature adjusting rate corresponding to the air conditioner of the room corresponding to the temperature difference value with the large absolute value as the temperature adjusting rate corresponding to the temperature difference value with the large absolute value. For example, a first air conditioner of a first room corresponds to a temperature regulation rate, a second air conditioner of a second room corresponds to a temperature regulation rate, and the temperature regulation rate corresponding to the first air conditioner is determined as the first temperature regulation rate corresponding to the first temperature difference when the absolute value of the first temperature difference is greater than the absolute value of the second temperature difference; and under the condition that the absolute value of the second temperature difference is larger than the absolute value of the first temperature difference, determining the temperature regulation rate corresponding to the second air conditioner as the second temperature regulation rate corresponding to the second temperature difference. That is, the temperature adjustment rate corresponding to the temperature difference value with the large absolute value is a preset value, and the temperature adjustment rate corresponding to the temperature difference value with the small absolute value is a calculated value.
Or determining the temperature adjusting rate corresponding to the air conditioner of the room corresponding to the temperature difference value with the small absolute value as the temperature adjusting rate corresponding to the temperature difference value with the small absolute value. For example, a first air conditioner of a first room corresponds to a temperature regulation rate, a second air conditioner of a second room corresponds to a temperature regulation rate, and the temperature regulation rate corresponding to the first air conditioner is determined as the first temperature regulation rate corresponding to the first temperature difference when the absolute value of the first temperature difference is smaller than the absolute value of the second temperature difference; and under the condition that the absolute value of the second temperature difference is smaller than the absolute value of the first temperature difference, determining the temperature regulation rate corresponding to the second air conditioner as the second temperature regulation rate corresponding to the second temperature difference.
