The air conditioners of the two rooms are controlled by adopting a traditional control method respectively, and under the condition that the two rooms are heated, the indoor temperature of the room with higher temperature reaches the set temperature first; in the case where both rooms are cooled, the indoor temperature of the room having a lower temperature first reaches the set temperature.
Before the indoor temperature in the room does not reach the set temperature, the running power of the air conditioner is corresponding to the temperature difference between the indoor temperature of the room and the set temperature, and the heat flow of the room and the other room; when the indoor temperature of the first room reaches the set temperature, the indoor temperature of the first room fluctuates around the set temperature, at the moment, the running power of the air conditioner in the first room corresponds to the heat flow between the two rooms, and then the temperature difference between the two rooms is reduced along with the change of the indoor temperature of the second room, so that the heat flow between the two rooms is reduced, and the fluctuation of the indoor temperature of the first room is further 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 is changed 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 further, the fluctuation of the indoor temperature of the second room around the set temperature is larger due to the larger hysteresis of the temperature of the room relative to the operation power of the air conditioner.

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, 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.
In a home, 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, in order to increase user 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.
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.
In a specific application, the first indoor temperature may be subtracted from the set temperature to obtain a first temperature difference, and the second indoor temperature may be subtracted from the set temperature to obtain a second temperature difference.
S203, determining a first temperature regulating rate positively correlated with the first temperature difference value and a second temperature regulating rate positively correlated with the second temperature difference value.
And enabling the ratio difference value of the first ratio of the first temperature difference value to the first temperature regulating rate to the second ratio of the second temperature difference value to the second temperature regulating rate to be in a preset difference value range.
The first temperature adjustment rate refers to a change rate of a first indoor temperature of the first room under the adjustment of the first air conditioner; the second temperature adjustment rate refers to a rate of change of a second indoor temperature of the second room under the adjustment of the second air conditioner. Under the condition that the first indoor temperature and the second indoor temperature are both smaller than the set temperature, the first temperature regulating rate and the second temperature regulating rate are both temperature rising rates; under the condition that the first indoor temperature and the second indoor temperature are both larger than the set temperature, the first temperature regulating rate and the second temperature regulating rate are both cooling rates.
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 ratio difference between the first ratio and the second ratio is within a preset difference range, and may indicate a duration required for the first indoor temperature of the first room to reach the set temperature, which is substantially the same as a duration 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 temperature adjustment power (cooling power or heating power) of the first air conditioner, the larger the upper limit value of the first temperature adjustment rate; the smaller the temperature adjustment power (cooling power or heating power) of the first air conditioner is, the smaller the upper limit value of the first temperature adjustment 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 temperature adjustment power (refrigerating power or heating power) of the second air conditioner is, the larger the upper limit value of the second temperature adjustment rate is; the smaller the temperature adjustment power (cooling power or heating power) of the second air conditioner is, the smaller the upper limit value of the second temperature adjustment 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 may be a desired time period), and may be an average temperature adjustment rate of the air conditioner to the room (i.e., the first ratio or the second ratio is an average time period required to eliminate a certain temperature difference) according to the existing temperature control method of the independent room.
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 such that a first ratio of the first temperature difference to the first temperature rate and a second ratio of the second temperature difference to the second temperature adjustment rate are within a preset difference range includes:
determining a temperature difference value with a large absolute value from the first temperature difference value and the second temperature difference value; according to the ratio of the temperature difference value with the large absolute value to the corresponding temperature adjustment rate, determining the temperature adjustment rate corresponding to the temperature difference value with the smaller absolute value in the first temperature difference value and the second temperature difference value; respectively controlling the corresponding air conditioners according to the two temperature regulating rates;
or alternatively, the process may be performed,
determining a temperature difference value with a small absolute value from the first temperature difference value and the second temperature difference value; according to the ratio of the temperature difference value with small absolute value to the corresponding temperature adjustment rate, determining the temperature adjustment rate corresponding to the temperature difference value with larger absolute value in the first temperature difference value and the second temperature difference value; and respectively controlling the corresponding air conditioners according to the two temperature regulating rates.
And determining the temperature adjustment rate corresponding to the air conditioner of the room corresponding to the temperature difference value with the large absolute value as the temperature adjustment rate corresponding to the temperature difference value with the large absolute value. For example, a first air conditioner in a first room corresponds to a temperature adjustment rate, a second air conditioner in a second room corresponds to a temperature adjustment rate, and when the absolute value of the first temperature difference is greater than the absolute value of the second temperature difference, the temperature adjustment rate corresponding to the first air conditioner is determined to be the first temperature adjustment rate corresponding to the first temperature difference; and determining the temperature adjustment rate corresponding to the second air conditioner as a second temperature adjustment rate corresponding to the second temperature difference value under the condition that the absolute value of the second temperature difference value is larger than that of the first temperature difference value. That is, the temperature adjustment rate corresponding to the temperature difference value with a large absolute value is a preset value, and the temperature adjustment rate corresponding to the temperature difference value with a small absolute value is a calculated value.
Or determining the temperature adjustment rate corresponding to the air conditioner of the room corresponding to the temperature difference value with small absolute value as the temperature adjustment rate corresponding to the temperature difference value with small absolute value. For example, a first air conditioner in a first room corresponds to a temperature adjustment rate, a second air conditioner in a second room corresponds to a temperature adjustment rate, and when the absolute value of the first temperature difference is smaller than the absolute value of the second temperature difference, the temperature adjustment rate corresponding to the first air conditioner is determined as the first temperature adjustment rate corresponding to the first temperature difference; and determining the temperature adjustment rate corresponding to the second air conditioner as a second temperature adjustment rate corresponding to the second temperature difference value under the condition that the absolute value of the second temperature difference value is smaller than that of the first temperature difference value.
