Referring to fig. 1, a method for controlling an air conditioner includes:
s101, obtaining the heat exchange state of the first room and the whole environment.
The first room here refers to a special room like a storage room, a bathroom, etc. that does not require a temperature balance, for example, the indoor temperature of the storage room can be ignored and is not adjusted; the indoor temperature of the bathroom can be made to be higher than the balance temperature of the whole environment.
The overall environment includes a room requiring temperature balance, and may be an overall scene in a home, or an overall environment of an office building or a factory.
The equilibrium temperature in the embodiment of the present disclosure means that the temperature difference between the indoor temperatures in the plurality of rooms is within a first preset temperature range, which may be [0, 3 ℃ ] or [0, 2 ℃ ], and the like.
The heat exchange state includes heat exchangeable and non-heat exchangeable. In order to obtain the heat exchange state between the first room and the whole environment, the opening and closing state of the first door can be obtained through a door opening and closing state detection device arranged on the door of the first room, and if the door of the first room is in a closed state, the heat exchange state between the first room and the whole environment can be regarded as non-heat exchange; if the door of the first room is in the open state, the heat exchange state of the first room with the whole environment is considered as heat exchangeable.
The room switch state detection device can be a proximity sensor and can also be a door magnet.
Optionally, obtaining a heat exchange state of the first room with the overall environment comprises: obtaining the communication time length of the first room and the whole environment within a set time length; determining the heat exchange state as heat exchangeable under the condition that the ratio of the communication duration to the set duration is greater than or equal to a preset ratio; and determining the heat exchange state as non-heat exchange under the condition that the ratio of the communication time length to the set time length is less than or equal to a preset ratio.
Starting timing when a door of a first room is switched from a closed state to an open state; when the door of the first room is switched from the open state to the closed state, ending timing; the above-mentioned connected time period may be a time period from the start of the timer to the end of the timer recording here.
The end time of the set time length is the current time, and the set time length can be 1min, 2min, 3min, 4min, 5min or longer.
The preset ratio may be 1/3, 1/4, 1/5 or less.
In some living scenes, a user goes in and out of a room, and there are several situations that the user may go to the room to pick and place articles, and in this situation, the indoor temperature of the room does not need to be adjusted, and if the technical scheme that the temperature of the room is adjusted by detecting that the room is in a heat exchange state with the whole environment is adopted, the air conditioner of the room is started mistakenly, and the indoor temperature of the room is adjusted.
The technical scheme that the ratio of the communication time length to the set time length is larger than or equal to the preset ratio and then the heat exchange state is determined to be heat exchange is adopted, the heat exchange state of one room can be more accurately determined, and the condition that the indoor temperature in the room is adjusted by mistake is reduced.
When the heat exchange state is not heat exchangeable, the first room is determined to be a room in which the temperature balance is not necessary, and the indoor temperature of the first room is ignored.
And S102, obtaining the temperature difference between the indoor temperatures of the rooms under the condition that the heat exchange state is heat-exchangeable.
Here, the temperature difference of the indoor temperatures of the respective rooms includes the indoor temperature of the first room. The temperature difference between the indoor temperatures of the respective rooms refers to the temperature difference between the indoor temperatures of every two rooms, for example, the number of the rooms in the whole environment, which need to be balanced, is three, and the rooms a, B and C are respectively provided, so that three temperature differences can be obtained: a temperature difference between the indoor temperature of the room a and the indoor temperature of the room B, a temperature difference between the indoor temperature of the room B and the indoor temperature of the room C, a temperature difference between the indoor temperature of the room a and the indoor temperature of the room C; likewise, if the number of rooms in the overall environment requiring equilibrium temperatures is four, six temperature differences may be obtained. The number of rooms and the temperature difference are merely exemplary, and those skilled in the art can obtain the temperature difference according with the actual situation by adopting the idea of obtaining the temperature difference in the embodiments of the present disclosure according to the actual situation.
And S103, obtaining the target temperature under the condition that the maximum value of the absolute values of the temperature difference values is out of a first preset temperature range.
The first predetermined temperature range may be [0, 3 ℃ ] or [0, 2 ℃ ], etc. If the maximum value of the absolute values of the temperature differences is within a first preset temperature range, the indoor temperatures of the rooms are relatively balanced at the moment and do not need to be adjusted; if the maximum value of the absolute values of the temperature differences is out of the first preset temperature range, it indicates that the indoor temperatures of the rooms are unbalanced, and balancing is needed. For example, the indoor temperatures of a plurality of rooms are each adjusted to a target temperature.
The one temperature is outside the first preset temperature range, which means that the one temperature is greater than the upper limit value of the first preset temperature range, or is less than the lower limit value of the first preset temperature range.
Optionally, obtaining a target temperature comprises: and obtaining a first average value of the indoor temperature of each room, and determining the first average value as the target temperature. Such a target temperature can more quickly equalize the indoor temperatures of the respective rooms.
And S104, adjusting the first air conditioner according to the target temperature to enable the indoor temperature of the first room to reach the target temperature.
In the process of adjusting the first air conditioner according to the target temperature, the indoor temperature of the first room is also required to be obtained, and the difference value between the target temperature and the indoor temperature of the first room is obtained, and then the controller of the first air conditioner outputs a control quantity according to the difference value between the target temperature and the indoor temperature of the first room, wherein the control quantity can adjust a compressor, a fan and the like of the first air conditioner. The controller of the first air conditioner refers to a controller in a conventional air conditioner, and may be, for example, a proportional-Integral-derivative (PID) controller.
Optionally, the determination that the indoor temperature of the first room reaches the target temperature comprises: and determining that the indoor temperature of the first room reaches the target temperature under the condition that the absolute value of the difference value between the indoor temperature of the first room and the target temperature is within a second preset temperature range. The absolute value of the difference between the indoor temperature of the first room and the target temperature is within a second preset temperature range, which means that the absolute value of the difference between the indoor temperature of the first room and the target temperature is greater than or equal to the lower limit value of the second preset temperature range, and the absolute value of the difference between the indoor temperature of the first room and the target temperature is less than or equal to the upper limit value of the second preset temperature range. The second predetermined temperature range here is smaller than the first predetermined temperature range described above, for example, the second predetermined temperature range may be [0, 1 ℃ ].
In general, doors of special rooms such as a storage room and a bathroom are closed, the special rooms are insulated from other rooms, if the first room and the whole environment are in a heat exchange state, the first room is described as the special room, and at the moment, a technical scheme of balancing the household temperature is performed on the first room, so that the indoor temperature of the first room reaches a target temperature. By adopting the technical scheme, the temperature in the room in the family can be balanced under the condition that the family has a scene similar to a special room without temperature balancing, such as a storage room, a bathroom and the like.
Fig. 2 is a schematic diagram of a method for controlling an air conditioner according to an embodiment of the present disclosure. Referring to fig. 2, a method for controlling an air conditioner includes:
s201, when the heat exchange state is switched from non-heat exchange to heat exchange, obtaining a second average value of the indoor temperatures of other rooms except the first room.
Here, the other room than the first room refers to a room in which temperature balancing is required.
S202, obtaining the indoor temperature of the first room.
And S203, adjusting the first air conditioner of the first room according to the second average value and the indoor temperature of the first room to enable the indoor temperature of the first room to reach the second average value.
According to the technical scheme in fig. 1, if the heat exchange state of the first room is heat exchangeable, a first average value of the indoor temperatures of all rooms including the first room needs to be obtained, and then the first average value is used as a target temperature to adjust the indoor temperature of the first room. Since the first room belongs to a room without a balance temperature before the first room is switched from the non-heat-exchange state to the heat-exchange state, the indoor temperature of the first room may be much higher than the indoor temperatures of other rooms, or the indoor temperature of the first room may be much lower than the indoor temperatures of other rooms, so that the indoor temperature of the first room has a greater influence on the first average value and a greater influence on the target temperature, and if the indoor temperature of the first room is much higher than the indoor temperatures of other rooms, the indoor temperature of the first room will be increased by the target temperature; if the indoor temperature of the first room is far less than the indoor temperatures of the other rooms, the indoor temperature of the first room will lower the target temperature, and the user experience will be reduced no matter the target temperature is increased or the target temperature is lowered.
In the technical scheme, the second average value of the indoor temperatures of other rooms except the first room is obtained, the indoor temperature of the first room is adjusted in the subsequent steps according to the second average value, and the indoor temperatures of all the rooms can still be balanced after the indoor temperature of the first room reaches the second average value, so that the influence of the indoor temperature of the first room on the target temperature of the whole environment can be reduced, and the use experience of a user is improved.
In specific application, in order to adjust the indoor temperature of the first room, a difference between the second average value and the indoor temperature of the first room may be obtained, the difference is input to the controller of the first air conditioner, a control quantity corresponding to the difference is obtained, and the control quantity is used to adjust the compressor frequency, the fan rotation speed, and the like of the air conditioner, so as to finally achieve adjustment of the indoor temperature of the first room.
Or, a first air conditioner for adjusting the first room according to the second average value and the indoor temperature of the first room, comprising: obtaining a difference value between the second average value and the indoor temperature of the first room; obtaining a first control quantity corresponding to the difference value output by the controller of the first air conditioner according to the difference value; determining a second control quantity according to the difference value and the expected duration; and controlling the first air conditioner according to the sum of the first control amount and the second control amount.
The difference between the second average value and the indoor temperature of the first room may also represent the amount of heat required for the indoor temperature of the first room to reach the second average value, such as: q is cm Δ T, c is the specific heat capacity of the air in the first room, m is the air mass in the first room, Δ T is the difference between the second average value and the room temperature in the first room, and Q is the heat required by the room temperature in the first room to reach the second average value. In the above formula, the air specific heat capacity c is a constant value, and the air mass m is a constant value, and it can be seen that the heat Q required for the indoor temperature of the first room to reach the second average value has a direct proportional relationship with the difference Δ T between the second average value and the indoor temperature of the first room.
The desired time period represents a desired time period for adjusting the indoor temperature of the first room to the second average value, and may be a fixed value, for example, the desired time period may be 3min, 4min, 5min, 6min or more. The desired time period and the difference between the second average value and the indoor temperature of the first room are fed forward to the first air conditioner, so that the speed of adjusting the indoor temperature of the first room by the first air conditioner can be increased, and the time period for adjusting the indoor temperature of the first room to the second average value can be shortened.
Optionally, the second control quantity is positively correlated with the difference, and the second control quantity is inversely correlated with the set time length. In this way, the difference between the second average value and the indoor temperature of the first room and the desired time period may be used to indicate a desired rate of heat exchange of the first air conditioner with the first room, which may more accurately adjust the first air conditioner.
The desired time period may also be a time period that is positively correlated to the difference between the second average value and the indoor temperature of the first room, which may cause the first air conditioner to adjust the indoor temperature of the first room to the second average value at a desired rate.
In some specific applications, the second control amount may be obtained by:
c2＝f(Tcoil pipe) (ii) a Wherein, c2Is a second control quantity, T Coil pipeF represents the mapping relation between the temperature of the internal coil of the first air conditioner and the control quantity, for example, in the case of heating, the working frequency of the compressor is increased, and the temperature of the internal coil can be increased; under the condition of refrigeration, the working frequency of the compressor is increased, andthe temperature of the inner coil pipe is reduced;
Tcoil pipe＝(cm△T)/te+T1(ii) a Wherein c is the specific heat capacity of the air in the first room, m is the air quality in the first room, Δ T is the difference between the second average value and the indoor temperature of the first room, TeTo a desired duration, T1Is the indoor temperature of the first room.
