In the embodiment of the present disclosure, the character "/" indicates that the preceding and following objects are in an or relationship. For example, A/B represents: a or B.
The term "and/or" is an associative relationship that describes objects, meaning that three relationships may exist. For example, a and/or B, represents: a or B, or A and B.
Referring to fig. 1, a method for controlling an air conditioner according to an embodiment of the present disclosure includes:
and S101, obtaining the temperature adjusting power required by the room.
In the embodiments of the present disclosure, the term "tempering power" refers to the amount of heat provided to a room per unit time, or the amount of heat absorbed in a room per unit time (i.e., the amount of cold provided to a room per unit time). The required tempering power means: the actual amount of heat supplied to the room per unit time is required to adjust the indoor ambient temperature to the set temperature, or the actual amount of cold supplied to the room per unit time is required to adjust the indoor ambient temperature to the set temperature. Wherein, the required temperature adjusting power comprises required refrigerating power and required heating power. Under the refrigeration working condition, the required temperature regulation power is the required refrigeration power; and under the heating condition, the required temperature adjusting power is the required heating power.
The required temperature adjusting power of a room can be represented by a gear, for example, the higher the gear is, the larger the required temperature adjusting power of the room is, the lower the gear is, the smaller the required temperature adjusting power of the room is; or the lower the gear is, the larger the required temperature adjusting power of the room is, and the higher the gear is, the larger the required temperature adjusting power of the room is. The gear can be manually selected by a user, and can be automatically selected by the air conditioner according to the condition of a room, for example, the larger the indoor space is, the higher the required temperature-adjusting power is; the smaller the indoor space, the lower the required tempering power.
And S102, determining the starting power of the air conditioner according to the required temperature adjusting power.
The starting power of the air conditioner is the power when the air conditioner is started, and the starting power is not higher than the highest power of the air conditioner. After the starting power of the air conditioner is determined, the air conditioner is started at the starting power. The starting power may be expressed by an operation frequency of the compressor, or the starting power may be expressed by an operation power of the compressor, and a rotation speed of the indoor fan and a rotation speed of the outdoor fan.
The positive correlation relationship is formed between the required temperature-adjusting power and the starting power of the air conditioner: the higher the required temperature adjusting power is, the higher the starting power of the air conditioner is; the lower the required tempering power, the lower the starting power of the air conditioner. Optionally, the starting power of the air conditioner is directly determined according to the required temperature adjusting power and the starting power of the air conditioner according to the mapping relation between the required temperature adjusting power and the starting power of the air conditioner.
Optionally, determining the starting power of the air conditioner according to the required temperature adjusting power includes: determining that the air conditioner is started in a high-power mode under the condition that the required temperature regulation power is greater than or equal to the set temperature regulation power; and determining that the air conditioner is started in a low power mode under the condition that the required temperature adjusting power is less than the set temperature adjusting power. The set temperature adjusting power can be a factory set value or a user set value. Determining that the air conditioner is started in a high-power mode, namely determining that the starting power of the air conditioner is higher, and operating in the high-power mode after the air conditioner is started; the air conditioner is determined to be started in the low-power mode, namely the starting power of the air conditioner is determined to be low, and the air conditioner runs in the low-power mode after being started. In this way, a suitable starting power can be selected for the air conditioner.
Optionally, the air conditioner is started in a high power mode, comprising: the power of the air conditioner after being started is greater than or equal to the first set power, for example, the air conditioner is directly started with a specific power greater than or equal to the first set power, and the specific power is maintained after the air conditioner is started; or the lower limit power after the air conditioner is started is larger than or equal to the first set power, for example, when the air conditioner is started, obtaining the difference between the indoor environment temperature and the set temperature, calculating the starting power of the air conditioner according to the difference, when the calculated starting power of the air conditioner is smaller than the first set power, the air conditioner is started with the first set power, when the calculated starting power of the air conditioner is greater than or equal to the first set power, the air conditioner is started by the calculated starting power of the air conditioner, obtaining the difference between the indoor environment temperature and the set temperature again, calculating the running power of the air conditioner according to the difference, when the calculated operation power is less than the first set power, the air conditioner is controlled to operate by the first set power, and when the calculated operating power of the air conditioner is greater than or equal to the first set power, controlling the air conditioner to operate according to the calculated operating power. In this way, the starting power of the air conditioner can be determined, and the running state of the air conditioner starting can be controlled.
Optionally, the air conditioner is started in a low power mode, including: the power of the air conditioner after being started is smaller than the second set power, for example, the air conditioner is directly started with a specific power lower than the second set power, and the specific power is kept after the air conditioner is started; or, the upper limit power after the air conditioner is started is less than the second set power, for example, when the air conditioner is started, the difference between the indoor environment temperature and the set temperature is obtained, the start power of the air conditioner is calculated according to the difference, when the calculated start power of the air conditioner is less than or equal to the second set power, the air conditioner is started according to the calculated start power of the air conditioner, when the calculated start power of the air conditioner is greater than the second set power, the air conditioner is started according to the second set power, after the air conditioner is started, the difference between the indoor environment temperature and the set temperature is obtained again, the operating power of the air conditioner is calculated according to the difference, when the calculated operating power is less than or equal to the second set power, the air conditioner is controlled according to the calculated operating power of the air conditioner, when the calculated operating power of the air conditioner is greater than the second set power, the air conditioner is controlled to, obtaining the difference value of the indoor environment temperature and the set temperature, calculating the starting power of the air conditioner through the difference value, then calculating the ratio of the starting power to the maximum running power of the air conditioner, calculating the product of the second preset power and the ratio, obtaining the starting power of the air conditioner, starting the air conditioner with the starting power of the air conditioner, obtaining the difference value of the indoor environment temperature and the set temperature after the air conditioner is started, calculating the running power of the air conditioner through the difference value, then calculating the ratio of the running power to the maximum running power of the air conditioner, calculating the product of the second preset power and the ratio, obtaining the running power of the air conditioner, and controlling the running of the air conditioner with the running frequency. In this way, the starting power of the air conditioner can be determined, and the running state of the air conditioner starting can be controlled.
Optionally, the first set power is greater than or equal to the second set power.
When the difference value between the indoor environment temperature and the set temperature is too large, the starting power of the air conditioner is determined according to the required temperature adjusting power instead of directly starting the air conditioner with high power, so that the rapid fluctuation of the indoor environment temperature can be avoided, and the electric energy is saved. For example, in the heating condition, when the indoor environment temperature is low, the temperature adjusting power required by the room is obtained, and the air conditioner is started at low power under the condition that the temperature adjusting power required by the room is low, so that the indoor environment temperature cannot be rapidly increased, the fluctuation amplitude of the indoor environment temperature in the vicinity of the set temperature is reduced, and the electric energy is saved; under the refrigeration working condition, when the indoor environment temperature is higher, the required adjusting power of the room is obtained, and under the condition that the required adjusting power of the room is smaller, the air conditioner is started at low power, so that the indoor environment temperature cannot be sharply reduced, the fluctuation range of the indoor environment temperature near the set temperature is reduced, and the electric energy is saved.
Referring to fig. 2, obtaining the required room temperature-adjusting power includes:
s201, obtaining the heat exchange rate between the inside and the outside of the room.
In the disclosed embodiments, the heat exchange rate refers to: heat transferred from indoor to outdoor in unit time; or heat transferred from outdoor to indoor per unit time. Under the heating condition, heat transmitted from indoor to outdoor in unit time is obtained; under the refrigeration working condition, heat transmitted from the outdoor to the indoor in unit time is obtained. The heat exchange rate can be represented by a shift, for example, a higher shift indicates a faster heat exchange rate, and a lower shift indicates a slower heat exchange rate; alternatively, a higher gear indicates a slower heat exchange rate, and a lower gear indicates a faster heat exchange rate. The heat exchange rate can be set when the air conditioner leaves a factory or manually set by a user.
Alternatively, the heat exchange rate is obtained by:
QCL＝KSΔt
wherein Q isCLThe heat exchange rate is K, the heat transfer coefficient is S, the wall area of the room is S, and the temperature difference between the indoor temperature and the outdoor temperature is delta t. Under the refrigeration working condition, obtaining an indoor and outdoor temperature difference by subtracting the indoor ambient temperature from the outdoor ambient temperature; under the heating condition, the indoor and outdoor temperature difference is obtained by subtracting the outdoor ambient temperature from the indoor ambient temperature. Therefore, the real-time and accurate heat exchange rate can be obtained according to the actual use working condition of the air conditioner.
And S202, obtaining the theoretical temperature regulation rate of the room.
In the disclosed embodiment, the theoretical tempering rate of a room refers to: theoretical heat quantity transmitted to the indoor in unit time in order to adjust the indoor environment temperature to the set temperature; alternatively, in order to adjust the indoor ambient temperature to the set temperature, the theoretical amount of heat absorbed in the room per unit time (i.e., the theoretical amount of cold transferred to the room per unit time) is calculated. Under the refrigeration working condition, obtaining the theoretical cold quantity transmitted to the indoor in unit time; under the heating condition, the theoretical heat transmitted to the indoor in unit time is obtained. The theoretical temperature regulation rate can be represented by gears, for example, the higher the gear is, the faster the theoretical temperature regulation rate is, and the lower the gear is, the slower the theoretical temperature regulation rate is; or the higher the gear is, the slower the theoretical temperature regulation rate is, and the lower the gear is, the faster the theoretical temperature regulation rate is. The theoretical temperature regulation rate can be set when the air conditioner leaves a factory or manually set by a user.
Alternatively, the theoretical tempering rate is obtained by:
Qi＝qF
wherein Q isiThe theoretical tempering rate. q is a heat index of a unit area, and under the refrigeration working condition, q is 130W-180W and can be any one of 130W, 140W, 150W, 155W, 160W, 170W and 180W; under the heating condition, q is 150-200W, and can be any one of 150W, 160W, 170W, 175W, 180W, 190W and 200W. And F is the total area of the house.
Therefore, the accurate theoretical temperature regulation rate can be obtained according to the actual use working condition of the air conditioner.
And S203, calculating the sum of the heat exchange rate and the theoretical temperature regulation rate to obtain the required temperature regulation power.
Thus, the accurate required temperature adjusting power can be obtained.
The method comprises the steps of arranging a rotatable camera in a room, for example, at the installation position of an air conditioner, recording the distance between the camera and a wall as P, controlling the camera to rotate by a specific angle, measuring the length of the wall in the view of the specific angle as L, calculating L× P/2, obtaining the house area in the view, and calculating the product of L and the height of the wall, thus obtaining the wall area in the view.
Fig. 3 shows a schematic diagram of measuring the wall area and the total area of a room, which is a top view of the room, and a camera is arranged at the installation position of the air conditioner, wherein the specific angle is 10 °, L1 is the length of the wall in a view field, and P1 is the area of the camera and the wall, so that L1 × P1/2 is calculated to obtain the area of the view field, and L2, L3 … … L36 (not shown in the figure) are sequentially obtained to calculate the wall area and the total area of the room.

The setting time is 3min to 15min, for example, any one of 3min, 5min, 7min, 10min and 15 min. When the air conditioner is started in the low-power mode, the original operation mode refers to the low-power mode; when the air conditioner is started in the high-power mode, the original operation mode refers to the high-power mode. Indoor ambient temperature reaches the settlement temperature, includes: under the refrigeration working condition, the indoor environment temperature is less than or equal to the set temperature, and under the heating working condition, the indoor environment temperature is greater than or equal to the set temperature. The indoor environment temperature does not reach the set temperature, and the method comprises the following steps: under the refrigeration working condition, the indoor environment temperature is greater than the set temperature, and under the heating working condition, the indoor environment temperature is less than the set temperature. Therefore, when the indoor environment temperature is found to be changed too severely in the operation process of the air conditioner, for example, under the cooling working condition, the indoor environment temperature is less than or equal to the set temperature within the set time, or under the heating working condition, the indoor environment temperature is greater than or equal to the set temperature within the set time, the operation power of the air conditioner is timely reduced, the fluctuation range of the indoor environment temperature at the set temperature can be reduced, and the energy consumption is further reduced.
