Based on the above hardware architecture of the air conditioner, an embodiment of the air conditioner control method of the present application is proposed.

Please refer to FIG. 2, which is a first embodiment of the air conditioner control method of the present application, which includes the following steps.
In step S10, the amount of change in the radiation temperature of the space in which the air conditioner is located at the target interval time is acquired.

In the present application, the subject of execution is the air conditioner. An array-type infrared thermocouple sensor is installed in the air conditioner, and the air conditioner acquires the environmental background temperature image by the array-type infrared thermocouple sensor, and the air conditioner acquires the environmental background temperature image once every predetermined time. , and the interval time can be the target interval time. After obtaining the environment background image, the air conditioner removes the heat source in the environment background image, and then calculates the average temperature of the environment, which is the radiation temperature. Therefore, the air conditioner can calculate the amount of change in radiation temperature that characterizes the amount of temperature change in the indoor walls, ground, etc., based on the environmental background temperature image acquired this time and the environmental background temperature image acquired last time. Also, a temperature sensor may be installed on the wall. This temperature sensor detects the temperature of the wall and transmits the temperature of the wall to the air conditioner for calculation of the amount of radiant temperature change by the air conditioner.

In step S20, target operating parameters are obtained by correcting the current operating parameters of the air conditioner according to the amount of change in radiation temperature.

The radiant temperature change can represent whether the current environment is too cold or too hot. Specifically, taking the cooling of the air conditioner as an example, when the air conditioner cools, the cold heat first contacts the air and then contacts the other objects in the room, that is, the air conditioner preferentially exchanges heat with the air. . If the amount of change in radiant temperature is large, it indicates that the amount of cold energy output by the air conditioner is large, and at the same time it is exchanging heat with the air, and at the same time, a large amount of heat is being exchanged with other items such as walls. is too cold. If the radiant temperature change amount is small, it means that the amount of cold energy output by the air conditioner is small and most of the cold energy is exchanging heat with the air. can be done.

On the other hand, the air conditioner can adjust the current operating parameters of the air conditioner according to the amount of change in the radiant temperature. The current operating parameter may be at least one of a set temperature and a set wind speed. The current operating parameters may be the comfort temperature and comfort wind speed corresponding to the user.

Specifically, air conditioners are divided into cooling type air conditioners, heating type air conditioners, and cooling and heating type air conditioners. Parameters can be adjusted. If the air conditioner is a cooling and heating air conditioner, the air conditioner should identify the mode it is currently operating in, and adjust the operating parameters of the air conditioner based on the mode, the amount of radiant temperature change, and a predefined mapping table. in particular,
If the current operating mode of the air conditioner is the cooling mode and the radiation temperature change amount is a positive value, the set temperature is lowered and/or the operating frequency of the compressor is raised and/or the rotation speed of the indoor fan is increased. raise,
When the current operating mode of the air conditioner is the cooling mode and the radiation temperature change amount is a negative value, the set temperature is raised and/or the operating frequency of the compressor is lowered and/or the rotation speed of the indoor fan lower the
If the current operating mode of the air conditioner is the heating mode and the radiation temperature change amount is a positive value, the set temperature is lowered and/or the operating frequency of the compressor is lowered and/or the rotation speed of the indoor fan is increased. lower,
When the current operating mode of the air conditioner is the heating mode and the radiation temperature change amount is a negative value, the set temperature is increased and/or the operating frequency of the compressor is increased and/or the rotational speed of the indoor fan Raise

Further, the air conditioner may determine a parameter adjustment value according to the section to which the radiant temperature change belongs, and then adjust the current operating parameters based on the parameter adjustment value. For example, if the current operating parameter is the set temperature, the air conditioner adjusts the set temperature based on Table-1. However, TSet is the set temperature, R is the radiation temperature change amount, and the target interval time is 10 minutes.

The air conditioner may determine the parameter adjustment value according to the radiation temperature change rate. For example, if the current operating parameter is the set temperature, the air conditioner adjusts the set temperature based on Table-2. where TSet is the set temperature, Ra is the radiation temperature change rate, Ra=R/T, R is the radiation temperature change amount, T is the target interval time, and the target interval time is 10 min.

If the current operating parameter is the rotation speed of the indoor fan, the air conditioner adjusts the rotation speed of the indoor fan based on R in Table-3. However, V is the rotational speed of the indoor fan, R is the radiation temperature variation, and the target interval time is 10 minutes.

If the current operating parameter is the rotation speed of the indoor fan, the air conditioner adjusts the rotation speed of the indoor fan based on Ra in Table-4. However, V is the rotational speed of the indoor fan, Ra is the radiation temperature change rate, Ra=R/T, R is the radiation temperature change amount, and the target interval time is 10 minutes.

If the current operating parameters are the rotation speed and set temperature of the indoor fan, the air conditioner adjusts the rotation speed and set temperature of the indoor fan based on R in Table-5 to obtain the target operating parameters. However, TSet is the set temperature, V is the rotational speed of the indoor fan, R is the radiation temperature change amount, and the target interval time is 10 minutes.

If the current operating parameters are the rotation speed and set temperature of the indoor fan, the air conditioner adjusts the rotation speed and set temperature of the indoor fan based on Ra in Table-6 to obtain the target operating parameters. However, TSet is the set temperature, V is the rotational speed of the indoor fan, Ra is the radiation temperature change rate, Ra=R/T, R is the radiation temperature change amount, and the target interval time is 10 minutes.

In addition, the numerical values in Tables 1 to 6 are merely for the purpose of facilitating the description of the adjustment of the current operating parameters of the air conditioner based on the amount of change in the radiation temperature. , need to be explained.

In step S30, the air conditioner is controlled to operate with the target operating parameters.

After the air conditioner determines the target operating parameters, the air conditioner operates with the target operating parameters, thereby adjusting the cold heat or heat output by the air conditioner.

In the technical solution provided by this embodiment, the air conditioner acquires the radiation temperature variation of the space in which the air conditioner is located within the interval time, and corrects the operating parameters according to the radiation temperature variation to obtain the target operating parameters. control the air conditioner to operate at the target operating parameters. The amount of change in radiant temperature can reflect whether the room is too cold or too hot. Indicates that the amount of change is large. For this reason, the air conditioner is made to reasonably adjust the amount of cold or hot heat output by the air conditioner according to the amount of change in the radiant temperature, to avoid the user from being in an environment that is too hot or too cold, and furthermore, to make the user feel comfortable. create a precise environment.

In one embodiment, the current operating parameters of the air conditioner are identified by the user's thermal sensation value of the space in which the air conditioner is located. The air conditioner can calculate the temperature sensation value of the user based on the environmental background temperature image fed back by the array type infrared thermocouple sensor.

Specifically, according to the first law of thermodynamics, the amount of heat released by the human body is approximately equal to the amount of heat consumed by the human body. can be done. The amount of heat consumed by the human body can be calculated by H=Φ(Tcl−Ra). where H is the amount of heat released from the human body, Tcl is the temperature value of the human body surface (the temperature value of the human body surface can be identified from the environmental background temperature image), Ta is the radiation temperature value, and Φ is the additional calculation coefficient. These calculation factors are some common calculation factors in the human body thermal comfort research field. Considering the effective radiation area coefficient f_eff of the ambient environment and the human body area coefficient f_cl of the clothing, Φ=f_eff*f_cl, and at this time, H=f_eff*f_cl*(Tcl−Ta). The difference value between the temperature value Tcl of the human body surface and the radiation temperature Ta is calculated and further multiplied by the calculation coefficient Φ to obtain the heat radiation amount H of the human body.
Of course, based on the mapping relationship between the temperature value Tcl of the human body surface, the radiation temperature value Ta, and the heat radiation amount of the human body, the temperature value Tcl and the temperature value Ta are obtained in advance, and the temperature value Tcl and the temperature value Ta correspond to each other. A mapping table may be created by setting the amount of heat released by the human body. Once the human body surface temperature value Tcl and the radiation temperature value Ta are obtained, the corresponding human body heat radiation amount can be obtained by examining the table.

The temperature sensation value of the human body is correlated with the amount of heat consumed by the human body, and the amount of heat consumed by the human body is equal to the amount of heat released by the human body. In the early stages of research and development of air conditioners, we conducted experiential tests for different users' thermal sensations, and based on the heat release values calculated at that time for different thermal sensations, we determined the relationship between the two using a fitting formula. be able to. For example, the relational expression between the temperature sensation state value M and the heat release amount H can be expressed as follows.
M=a0+a1H+a2H2+a3H3+ . . + an Hn

where a0, a1, a2, a3, an are different calculation coefficient values obtained by experiment, n is a positive value, and the magnitude of the value is between specific H and M data groups. N can take the value 4, for example. By calculating the human body's heat dissipation value H from the relational expression between the human body's temperature sensation value M and the heat dissipation amount H in the above equation, and then substituting it into the above equation, the human body's temperature sensation value M is obtained.

The temperature sensation value reflects the temperature of the human body. A larger value of M indicates a hotter temperature, and a smaller value of M indicates a colder temperature. In the cooling mode of the air conditioner, the larger the M value, the lower the set temperature of the air conditioner and the higher the wind speed. Conversely, the smaller the value of M, the higher the set temperature of the air conditioner and the lower the wind speed. In the heating mode of the air conditioner, the larger the M value, the lower the set temperature of the air conditioner and the lower the wind speed. Conversely, the smaller the value of M, the higher the set temperature and wind speed of the air conditioner.

In the technical solution provided by this embodiment, the air conditioner identifies the current operating parameters from the user's temperature sensation value, and further corrects the current operating parameters according to the amount of change in the radiation temperature, so that the air conditioner can use Accurately adjust its heat or cold output according to the temperature of the person and the temperature of the surrounding environment.

In one embodiment, the air conditioner includes an image acquisition module, which may be a camera. The air conditioner identifies the user in the space where the air conditioner is located by the image acquisition module, and if the number of users is only one, identifies the current operating parameters of the air conditioner with the user's temperature sensation value; When there are multiple users, the air conditioner must identify each user's information and identify the group to which the user belongs based on information such as age and gender in the user information. The groups are divided into the elderly, children, women, men, adolescents, and middle-aged, and the air conditioner sets the elderly, children, and women as default groups with weaker receptivity to air conditioning than other groups. For this reason, the air conditioner identifies the current operating parameters of the air conditioner using a predetermined group of user's thermal sensation values.

Furthermore, the default group may be one or more, and if there are more than one, a priority corresponding to each default group can be set. The air conditioner may use the occupant's thermal sensation value of the highest priority predetermined group to identify the current operating parameters of the air conditioner. The priority of the default group can be set by the user according to the actual situation of his/her home, and if the user does not set the priority of the default group, the priority of the default group is the priority set in advance in the air conditioner. become.

In the technical solution provided by this embodiment, when there are multiple users in the room, the current operating parameters of the air conditioner are determined according to the temperature sensation value of a predetermined group of users, so that the air conditioner can be used by the elderly, children, etc. It can set its own operating parameters according to the actual situation of the special group, and the intelligence of the air conditioner is high.

Referring to FIG. 3, FIG. 3 is a second embodiment of the air conditioner control method of the present application. Based on the first embodiment, after step S10, further:
A step S40 of determining a target interval time based on the interval to which the radiation temperature variation belongs is included.

after the step of controlling the air conditioner to operate with the target operating parameters, that is, after step S30, further comprising
a step S50 of acquiring a continuous operation time during which the air conditioner is operating with the target operation parameter;
and a step S60 of determining whether or not the continuous operation time has reached the target interval time.

When the continuous operation time reaches the target interval time, the process returns to the step of acquiring the amount of change in the radiation temperature of the space in which the air conditioner is located at the target interval time.

In this embodiment cooling, the air conditioner may determine the target interval time according to the amount of change in the radiation temperature. Specifically, when the amount of change in radiant temperature is large, it indicates that the air conditioner outputs too much cold or hot heat. , the amount of decrease in cold or hot heat increases, that is, the room temperature changes greatly in the following time periods. On the other hand, when the amount of radiant temperature change is large, the air conditioner avoids changing the indoor environment from too cold to too hot when the air conditioner cools, or changes the indoor environment from too hot to too cold when the air conditioner heats. The target interval time should be set small to avoid turning to . Thus, the air conditioner sets a plurality of intervals, each interval corresponds to one target interval time, and the larger the interval, the smaller the target interval time length is set.

After specifying the current amount of change in the radiation temperature, the air conditioner can set the target interval time based on the section to which the amount of change in the radiation temperature belongs. As a result, when the air conditioner operates with the target operating parameters, the timer is started to obtain the duration of operation with the target operating parameters of the air conditioner, and when the duration reaches the target interval time, the indoor air conditioner is restarted. To enable a user to be in a stable and comfortable environment by adjusting the environment, that is, adjusting circulation by an air conditioner.

In the technical solution provided by the present embodiment, the air conditioner determines the current radiant temperature change amount, and then determines the target interval time according to the section to which the radiant temperature change amount belongs, so that the air conditioner operates with the target operating parameters. When the continuous time reaches the target interval time, the operation parameters of the air conditioner are readjusted to allow the air conditioner to adjust the indoor environment at regular intervals, and the user is in a stable and comfortable environment. make it

Referring to FIG. 4, FIG. 4 is a third embodiment of the air conditioner control method of the present application. Based on the first or second embodiment, after step S10, further:
a step S70 of determining whether the amount of change in the radiation temperature is smaller than a first predetermined amount of change, wherein the air conditioner is in the cooling mode;
a step S80 of controlling the air conditioner to blow air away from the user when the amount of change in the radiant temperature is smaller than a first predetermined amount of change;
a step S90 of controlling the air conditioner to blow air toward the user when the radiation temperature change amount is greater than a second predetermined change amount that is greater than the first predetermined change amount;
including.

In this embodiment, the air conditioner may adjust the blowing direction of the air conditioner according to the radiation temperature change amount. Specifically, when the air conditioner is in the cooling mode, the amount of change in the radiant temperature is a negative value, and if the amount of change in the radiant temperature is small, it means that the room is too cold. is adjusted to adjust the air blowing direction so that the air conditioner blows air away from the user, and the discomfort given to the user in a too cold environment is reduced as much as possible. If the radiant temperature is a positive value and the amount of change in radiant temperature is large, it means that the room is too hot. At this time, adjust the angle of the air duct of the air conditioner to blow air toward the user. The control makes the user feel cooler and avoids the user feeling that the cooling effect of the air conditioner is poor.

The air conditioner sets a first predetermined amount of change and a second predetermined amount of change larger than the first predetermined amount of change. If the radiant temperature change amount is smaller than the first predetermined change amount, it indicates that the air conditioner outputs a large amount of cold heat, so the air conditioner is controlled to blow air away from the user, and the radiant temperature change amount is the first predetermined change amount. and the amount of change in radiant temperature is larger than the second predetermined amount of change, it indicates that the air conditioner has less cold heat, so at this time the air conditioner is controlled to blow air toward the user. Similarly, when the air conditioner is in heating mode, the air conditioner determines whether the user is too hot or too cold based on the magnitude of the radiant temperature change, and if the user is too hot, , the air may be directed away from the user, and directed toward the user if the user is too cold.

In the technical solution provided by this embodiment, the air conditioner controls the airflow direction according to the amount of change in the radiation temperature, so as to avoid the user feeling too hot or too cold, and make the air conditioner intelligent. High degree.
