￠＝(k ₁ ×k ₂ ×k ₃ +k ₄ ×k ₅ ×k ₆ ×k ₇ )÷2 (1)

It should be noted that the formula (1) for calculating the illumination coefficient is a formula obtained by the inventor through analyzing and summarizing a large amount of test data.

The following describes in detail how to selectively adjust the operating mode of the air conditioner according to the illumination coefficient and the temperature difference in combination with two embodiments.

Embodiment one

The technical solution of this embodiment will be described in detail below with reference to FIG. 2 to FIG. 4 .

As shown in FIG. 2, the operation mode control method of this embodiment includes the following steps:

Step S1: Obtain the illumination coefficient;

Step S2: Obtain the indoor temperature;

Step S3: Calculate the temperature difference between the indoor temperature and the target temperature;

Step S4: Selectively adjust the operating mode of the air conditioner according to the illumination coefficient and the temperature difference. Wherein, step S4 specifically includes the following steps:

Step S41: comparing the illumination coefficient with the first set coefficient;

Step S42: comparing the temperature difference with the first preset value;

Step S43: If the illumination coefficient is less than the first set coefficient and the temperature difference is less than the first preset value, make the air conditioner operate in the air supply mode;

Step S44: If the illumination coefficient is not less than the first set coefficient or the temperature difference is not less than the first preset value, then calculate the mode adjustment coefficient ΔM according to formula (2),

ΔM＝￠{(ΔT－ΔT ₁ )+M/(ΔT－ΔT ₁ )} (2)

Among them, ￠ is the illumination coefficient, ΔT is the temperature difference, ΔT ₁ is the first preset value, when the current operation mode of the air conditioner is the air supply mode, M=M ₁ , when the current operation mode of the air conditioner is the cooling mode Or in heating mode, M=M ₂ , where M ₁ is the first set value, M ₂ is the second set value, and M ₁ <M ₂ ;

Step S45: Selectively adjust the operating mode of the air conditioner according to the mode adjustment coefficient. Wherein, step S45 specifically includes the following steps:

Step S451: comparing the mode adjustment coefficient with a second preset value;

Step S452: If the mode adjustment coefficient is smaller than the second preset value, run the air conditioner in the air supply mode; if the mode adjustment coefficient is not smaller than the second preset value, make the air conditioner run in the cooling mode or the heating mode.

After the illumination coefficient and the temperature difference are calculated, the illumination coefficient is compared with the first set coefficient, the temperature difference is compared with the first preset value, and then the air conditioner is selectively adjusted according to the two comparison results. to adjust the operating mode.

When the illumination coefficient is less than the first set coefficient, it means that the external light conditions have little influence on the indoor temperature at this time; when the temperature difference is less than the first preset value, it means that the indoor temperature at this time is relatively close to the target temperature. When the above two conditions are met at the same time, the air conditioner can be directly operated in the air supply mode without calculating the mode adjustment coefficient, that is, the operation mode of the air conditioner can be adjusted from the cooling mode or the heating mode to the air supply mode. When the air supply mode is running, the indoor unit only supplies air to the room, neither cooling nor heating, so as to avoid affecting the comfort of the room because the temperature in the room is too low or too high.

When the illumination coefficient is not less than the first set coefficient, it indicates that the illumination situation at this time has a greater impact on the indoor temperature; when the temperature difference is not less than the first preset value, it indicates that the difference between the indoor temperature and the target temperature at this time is In either case, the mode adjustment coefficient needs to be calculated according to formula (2), and then the operating mode of the air conditioner is selectively adjusted according to the mode adjustment coefficient.

Specifically, the mode adjustment coefficient is compared with the second preset value, and when the mode adjustment coefficient is smaller than the second preset value, it indicates that the influence of the external light conditions on the indoor temperature is not particularly large, and the indoor temperature and the target temperature In this case, the air conditioner can also be operated in the air supply mode; when the mode adjustment coefficient is not less than the second preset value, it means that the external light conditions have a particularly large impact on the indoor temperature , and/or, the indoor temperature is also very different from the target temperature. In these cases, the air conditioner can only continue to operate in cooling mode or heating mode.

It should be noted that "making the air conditioner operate in cooling mode or heating mode" can be understood as, in summer, the air conditioner operates in cooling mode, and when the mode adjustment coefficient is greater than or equal to the second preset value, the air conditioner continues to Run in the cooling mode without switching to the air supply mode; in winter, the air conditioner runs in the heating mode, and when the mode adjustment coefficient is greater than or equal to the second preset value, the air conditioner continues to run in the heating mode without switching For air supply mode. That is to say, in summer, the operation mode of the air conditioner is switched between the cooling mode and the air supply mode, and in winter, the operation mode of the air conditioner is switched between the heating mode and the air supply mode.

In addition, it should be noted that the formula (2) for calculating the mode adjustment coefficient is also a formula obtained by the inventor through analyzing and summarizing a large amount of test data.

In addition, it should be noted that, as shown in Figure 2, step S41 (comparing the illumination coefficient with the first set coefficient) and step S42 (comparing the temperature difference with the first preset value) can be executed simultaneously; Or, as shown in Figure 3, step S41 (comparing the illumination coefficient with the first set coefficient) can be performed first, and if the illumination coefficient is less than the first set coefficient, then perform step S42 (comparing the temperature difference with the first preset coefficient). Set value for comparison), if the illumination coefficient is not less than the first set coefficient, then directly execute step S44 (calculate the mode adjustment coefficient); or, as shown in Figure 4, you can also first execute step S42 (combine the temperature difference and compare the first preset value), if the temperature difference is less than the first preset value, then perform step S41 (comparing the illumination coefficient with the first set coefficient), if the temperature difference is not less than the first preset value, Then directly execute step S44 (calculate mode adjustment coefficient).

The operation mode control method of this embodiment will be described in detail below by taking the operation of the air conditioner in cooling mode as an example.

First, the calculation method of the illumination coefficient is introduced, and the illumination coefficient can be calculated according to the following steps:

The first step is to obtain the current season information, current weather information and current time. Wherein, the controller of the air conditioner may communicate with the cloud server to obtain the above information. In addition, when installing the air conditioner, the climate of the place where the air conditioner is located, the indoor area of the room, the height and location of the room, and the lighting environment of the room can be directly input into the controller, without the need for the air conditioner to automatically obtain it.

In the second step, determine the first coefficient k ₁ , the second coefficient k ₂ , the third coefficient k ₃ , the fourth coefficient k ₄ , the fifth coefficient k ₅ , the sixth coefficient k ₆ , and the seventh coefficient k according to the following table 1 ₇ .

It should be noted that the determination of each coefficient in Table 1 mainly takes into account the influence of the indoor temperature under various conditions by the light conditions, and is determined by the inventor after studying and summarizing a large amount of test data. For example, according to the inventor's research, it is found that in summer, the indoor temperature is greatly affected by the light conditions, while in spring and autumn, the indoor temperature is less affected by the light conditions. Therefore, in summer, the first coefficient is taken as The value is larger, and the value of the first coefficient is smaller in spring and autumn.

_{The third step} is _according to the _{formula ¢ =} (k ₁ ×k ₂ ×k ₃ +k ₄ ×k ₅ ×k ₆ ×k ₇ )÷2 to calculate the illumination coefficient ¢.

In order to obtain the indoor temperature, a temperature sensor can be installed on the indoor unit, and the temperature sensor can communicate with the controller, so that the temperature sensor can transmit the collected data to the controller in time. After obtaining the indoor temperature, calculate the temperature difference between the indoor temperature and the target temperature.

The calculated illumination coefficient and temperature difference are compared with the first set coefficient and the first preset value respectively. Wherein, the first setting coefficient is 1, and the first preset value ΔT ₁ =0.5.

When ￠<1 and ΔT<0.5, adjust the air conditioner from cooling mode to air supply mode.

When ￠≥1 or ΔT≥0.5, calculate the mode adjustment coefficient ΔM according to the formula ΔM＝￠{(ΔT－ΔT ₁ )+M/(ΔT－ΔT ₁ )}; where, when the current mode of the air conditioner is the air supply mode , M=M ₁ , when the current mode of the air conditioner is cooling mode, M=M ₂ , the first set value M ₁ =1, the second set value M ₂ =2, the first preset value ΔT ₁ = 0.5.

The mode adjustment coefficient ΔM is compared with a second preset value. Wherein, the second preset value is 3.

When ΔM<3, the air conditioner is adjusted from cooling mode to air supply mode.

When ΔM≥3, if the air conditioner is running in the air supply mode, the air conditioner is adjusted from the air supply mode to the cooling mode, and if the air conditioner is in the cooling mode at this time, the air conditioner is continued to operate in the cooling mode.

The operation mode control method of this embodiment will be described in detail below by taking the operation of the air conditioner in the heating mode as an example.

First, the calculation method of the illumination coefficient is introduced, and the illumination coefficient can be calculated according to the following steps:

The first step is to obtain the current season information, current weather information and current time. Wherein, the controller of the air conditioner may communicate with the cloud server to obtain the above information. In addition, when installing the air conditioner, the climate of the place where the air conditioner is located, the indoor area of the room, the height and location of the room, and the lighting environment of the room can be directly input into the controller, without the need for the air conditioner to automatically obtain it.

In the second step, determine the first coefficient k ₁ , the second coefficient k ₂ , the third coefficient k ₃ , the fourth coefficient k ₄ , the fifth coefficient k ₅ , the sixth coefficient k ₆ , and the seventh coefficient k according to the following table two ₇ .

It should be noted that the determination of each coefficient in Table 2 mainly takes into account the influence of the indoor temperature under various conditions by the light conditions, and is determined by the inventor after studying and summarizing a large amount of test data.

_{The third step} is _according to the _{formula ¢ =} (k ₁ ×k ₂ ×k ₃ +k ₄ ×k ₅ ×k ₆ ×k ₇ )÷2 to calculate the illumination coefficient ¢.

In order to obtain the indoor temperature, a temperature sensor can be installed on the indoor unit, and the temperature sensor can communicate with the controller, so that the temperature sensor can transmit the collected data to the controller in time. After obtaining the indoor temperature, calculate the temperature difference between the indoor temperature and the target temperature.

The calculated illumination coefficient and temperature difference are compared with the first set coefficient and the first preset value respectively. Wherein, the first setting coefficient is 1, and the first preset value ΔT ₁ =0.5.

When ￠<1 and ΔT<0.5, adjust the air conditioner from cooling mode to air supply mode.

When ￠≥1 or ΔT≥0.5, calculate the mode adjustment coefficient ΔM according to the formula ΔM＝￠{(ΔT－ΔT ₁ )+M/(ΔT－ΔT ₁ )}; where, when the current mode of the air conditioner is the air supply mode , M=M ₁ , when the current mode of the air conditioner is cooling mode, M=M ₂ , the first set value M ₁ =1, the second set value M ₂ =2, the first preset value ΔT ₁ = 0.5.

The mode adjustment coefficient ΔM is compared with a second preset value; wherein, the second preset value is 3.

When ΔM<3, the air conditioner is adjusted from cooling mode to air supply mode.

When ΔM≥3, if the air conditioner is running in the air supply mode, the air conditioner is adjusted from the air supply mode to the cooling mode, and if the air conditioner is in the cooling mode at this time, the air conditioner is continued to operate in the cooling mode.

It should be noted that, due to the different operating modes, the influence by light is also different. Therefore, the inventors formulated Table 1 and Table 2 for cooling mode and heating mode respectively. In practical applications, if the air conditioner is a cooling-only air conditioner, you can only store Table 1 in the controller of the air conditioner; if the air conditioner is a heating and cooling air conditioner, you can store both Table 1 and Table 2 in the controller In the controller, when the air conditioner is running in cooling mode, the first coefficient k ₁ , the second coefficient k ₂ , the third coefficient k ₃ , the fourth coefficient k ₄ , the fifth coefficient k ₅ , and the sixth coefficient are determined according to Table 1 k ₆ and the seventh coefficient k ₇ , when the air conditioner operates in heating mode, determine the first coefficient k ₁ , the second coefficient k ₂ , the third coefficient k ₃ , the fourth coefficient k ₄ , and the fifth coefficient according to Table 2 k ₅ , sixth coefficient k ₆ and seventh coefficient k ₇ .

In addition, it should be noted that the specific numerical values of the above-mentioned parameters are all set according to test data. In practical applications, those skilled in the art can test the air conditioners involved in the present invention for different models or types of air conditioners. Each parameter is set.

Preferably, the operation mode control method of this embodiment further includes: if the illumination coefficient is less than the first set coefficient and the temperature difference is less than the first preset value and the indoor humidity is greater than the third preset value, the operation of the air conditioner The mode is adjusted to dehumidification mode.

When the illumination coefficient is less than the first set coefficient, it means that the illumination condition at this time has little influence on the indoor temperature; when the temperature difference is less than the first preset value, it means that the indoor temperature at this time is closer to the target temperature. When the humidity is greater than the third preset value, it means that the humidity in the room is relatively high. When the above three conditions are met at the same time, the air conditioner can be operated in a dehumidification mode to reduce the humidity in the room.

It should be noted that when the illumination coefficient is less than the first set coefficient and the temperature difference is less than the first preset value, but the indoor humidity is less than or equal to the third preset value, the air conditioner is operated in the air supply mode.

In addition, it should be noted that those skilled in the art may set the specific numerical value of the third preset value according to experiments or experience in practical applications.
