[0068] First, the application scenarios of this disclosure are described. In the related art, currently, air conditioner products in the industry are gradually developing towards intelligence and personalization. Some products are equipped with human presence detection devices to achieve functions such as intelligent air control. However, there are problems such as a single and simple control method, unsatisfactory temperature control effect, and poor user experience.

[0069] The present disclosure combines airflow simulation to optimize the gas flow trajectory and more precisely adjust the operating parameters of the air conditioner, such as the air deflector angle, compressor frequency, fan speed, and inner tube temperature, so as to achieve a more comfortable and energy-saving air conditioner usage experience. The present disclosure will be described below with reference to specific embodiments.

[0070] Figure 1 is a flowchart of an air conditioner control method shown according to an exemplary embodiment. As Figure 1 shown, the embodiments of the present disclosure provide an air conditioner control method, which may include the following steps:

[0071] In step S10, obtain the three-dimensional space information of the room and the personal characteristics in the room.

[0072] In this step, obtain the three-dimensional space information of the room and the personal characteristics in the room. Exemplarily, the three-dimensional space information of the room (room size, obstacles, furniture position and size) can be collected through information such as the echo signal intensity and delay time of the millimeter-wave radar, output relevant dimension information, and real-time monitor the moving coordinates of people to perform target trajectory tracking. An infrared sensor can be combined to detect the body surface temperature of the target person and the surrounding environment temperature. In addition, the room layout dimensions and obstacle information can also be obtained by means of the user uploading the house type diagram, the after-sales taking photos of the room layout, and the radar identifying and learning the room boundary.

[0073] In step S20, perform air fluid simulation according to the three-dimensional space information, the personal characteristics, and the operating mode of the air conditioner.

[0074] In this step, perform air fluid simulation according to the three-dimensional space information, the personal characteristics, and the operating mode of the air conditioner. Exemplarily, under different operating modes of the air conditioner, air fluid simulation can be performed according to the three-dimensional space information of the room and the personal characteristics. Using the existing fluid simulation algorithm, the room information collected by the millimeter-wave radar is three-dimensionally modeled to construct a three-dimensional model of the room layout. Combining the position of the air conditioner and the people, the air flow path is simulated through the computational fluid dynamics algorithm, and the airflow simulation calculation is performed to predict the air temperature propagation trend, the airflow distribution trajectory, and the room cold and heat concentration area.

[0075] In step S30, adjust the operating parameters of the air conditioner according to the result of the air fluid simulation, where the parameters include at least one of wind speed, air deflector angle, compressor frequency, fan speed, and inner tube temperature.

[0076] In this step, according to the results of the air fluid simulation, the operating parameters of the air conditioner are adjusted, and the parameters include at least one of the wind speed, the air deflector angle, the compressor frequency, the fan speed, and the inner tube temperature. Exemplarily, according to the personnel position coordinates and height, fluid simulation can be performed according to the set temperature and fan speed (i.e., the outlet air temperature and speed) of the user, which can clearly and intuitively show the air flow path and air distribution of the air conditioner. Thus, the optimal air deflector angle at which the air conditioner blows air towards the personnel at a certain wind speed and a certain height can be calculated, which is convenient for quickly adjusting the air deflector and accurately realizing application scenarios such as hot air blowing on the feet and preventing cold air from directly blowing on the head. Moreover, according to the change of the personnel position and coordinate movement, real-time simulation calculation can be performed to adjust the optimal air deflector angle.

[0077] In summary, the embodiments of the present disclosure provide an air conditioner control method, including: obtaining three-dimensional space information of a room and the personnel characteristics in the room; performing air fluid simulation according to the three-dimensional space information, the personnel characteristics, and the operating mode of the air conditioner; and adjusting the operating parameters of the air conditioner according to the results of the air fluid simulation, where the parameters include at least one of the wind speed, the air deflector angle, the compressor frequency, the fan speed, and the inner tube temperature. The embodiments of the present disclosure can combine airflow simulation to optimize the gas flow trajectory and more accurately adjust operating parameters such as the air deflector angle, the compressor frequency, the fan speed, and the inner tube temperature of the air conditioner, so as to achieve a more comfortable and energy-saving air conditioner usage experience.

[0079] In step S201a, air fluid simulation is performed according to the position coordinates and the height, in combination with the set temperature and the set fan speed, and the air fluid simulation is used to predict the air flow path and the temperature propagation trend.

[0080] In this step, air fluid simulation is performed according to the position coordinates and the height, in combination with the set temperature and the set fan speed, and the air fluid simulation is used to predict the air flow path and the temperature propagation trend. Exemplarily, the target positioning blowing mode may be a conventional blowing mode for people. In this operating mode, air fluid simulation can be performed according to the personnel position, height, in combination with the set temperature and the set fan speed of the air conditioner, and the air fluid simulation is used to predict the air flow path and the temperature propagation trend.

[0081] In step S202a, a target air deflector angle that meets a preset wind speed and blowing height is obtained according to the simulation result, and the blowing height is obtained based on the height parameter.

[0082] In this step, a target air deflector angle that meets a preset wind speed and blowing height is obtained according to the simulation result, where the blowing height can be obtained based on the personnel height parameter. This can improve the usage efficiency of the air conditioner, enhance the user experience, and save energy and reduce consumption.

[0085] In this step, the movement trajectory of the person is obtained. Exemplarily, the movement situation of the person can be fed back in real time by a millimeter-wave radar to generate the movement trajectory of the person.

[0086] In step S302a, the target air deflector angle is corrected according to the movement trajectory.

[0087] In this step, the target air deflector angle is corrected according to the movement trajectory. Exemplarily, the target air deflector angle can be corrected in real time according to the movement trajectory to achieve tracking air supply to the person, further enhancing the user experience.

[0088] Figure 4 is a flowchart of an air conditioner control method shown according to an exemplary embodiment. The air conditioner operation mode includes a comfortable wind mode, and the personnel characteristics include the position coordinates, height, and body surface temperature of the person. As Figure 4 shown, performing air fluid simulation according to the three-dimensional space information, the personnel characteristics, and the operation mode of the air conditioner may include the following steps:

[0089] In step S201b, the environmental temperature field of the room is obtained.

[0090] In this step, the environmental temperature field of the room is obtained. Exemplarily, the comfortable wind mode can be a comfortable air control mode. In this operation mode, the position coordinates and height data of the person in the room can be obtained by a millimeter-wave radar, and the body surface temperature data of the person in the room and the environmental temperature distribution around the person, that is, the environmental temperature field of the room, can be obtained by a temperature sensor.

[0091] In step S202b, according to the position, height, body surface temperature of the person, and the environmental temperature field of the room, multi-objective parameter fluid simulation is performed. The multi-objective parameter fluid simulation is used to predict the air flow path and temperature propagation trend under multiple target parameters. The multiple target parameters include target wind speed, target pipe temperature, target compressor frequency, and target air deflector angle.

[0092] In this step, according to the position, height, body surface temperature of the person, and the environmental temperature field of the room, multi-objective parameter fluid simulation is performed. The multi-objective parameter fluid simulation is used to predict the air flow path and temperature propagation trend under multiple target parameters. Exemplarily, the multi-objective parameter fluid simulation can be performed according to a preset simulation model for a predetermined model of air conditioner with the goal of obtaining the best user experience and the minimum energy consumption, so as to obtain the optimal combination relationship of the multiple target parameters. Among them, the multiple target parameters include target wind speed, target pipe temperature, target compressor frequency, and target air deflector angle.

[0093] In step S203b, according to the simulation results, the combination relationship of the multiple target parameters is obtained.

[0094] In this step, according to the simulation results, the combination relationship of the multiple target parameters is obtained. Exemplarily, the combination relationship may include the following formula:

[0095] V(θ,d,h,nf,fc,Tpipe)=C*cos(θ)*nf / (d∧α)*e-βh*(1+γTpipe)*fc,

[0096] where d is the distance between the person and the air conditioner obtained according to the person's position, h is the person's height, nf is the target fan speed, fc is the target compressor frequency, Tpipe is the target pipe temperature, θ is the target air deflector angle, C is a correction coefficient, and α, β, and γ are empirical parameters.

[0101] In this step, temperature regulation is preferentially performed on the target area. Exemplarily, temperature regulation can be preferentially and sequentially performed on the target areas passed by the movement path of the person to improve the user experience and reduce the air conditioner energy consumption.

[0102] Figure 6 is a flowchart of an air conditioner control method shown according to an exemplary embodiment. The air conditioner operating modes include a uniform temperature control mode, such as Figure 6 shown, performing air fluid simulation according to the three-dimensional space information, the person characteristics, and the operating mode of the air conditioner may include the following steps:

[0103] In step S201c, a temperature distribution heat map of the room is obtained, and the temperature distribution heat map includes different temperature regions of the room.

The temperature distribution heat map includes different temperature regions of the room. Exemplarily, different temperature regions of the room can be obtained through temperature sensors, and then the temperature distribution heat map of the room is obtained. This heat map characterizes the temperature distribution of different regions in the room.

[0105] In step S202c, according to the temperature distribution heat map, hot spots, cold spots, and the regional temperature difference between different temperature regions of the room are identified.

[0106] In this step, according to the temperature distribution heat map, hot spots, cold spots, and the regional temperature difference between different temperature regions of the room are identified.

[0116] In this step, the zoning temperature control mode may be an indoor zoning temperature control mode. In this operation mode, the energy loss area of the room is identified by a temperature sensor, and a heat conduction model of the room is established according to a preset simulation tool. The energy loss area includes the door and window areas of the room. This can avoid unnecessary energy loss caused by directly blowing cold and hot air to energy loss areas such as doors and windows when the air conditioner is turned on through subsequent air flow simulation.

[0117] In step S202d, set the basic temperature of the unoccupied area and the comfortable temperature of the occupied area, and the basic temperature is less than the comfortable temperature.

[0118] In this step, set the basic temperature of the unoccupied area and the comfortable temperature of the occupied area according to the heat conduction model, and the basic temperature is less than the comfortable temperature. Exemplarily, the comfortable temperature of the occupied area may be 20 degrees Celsius, and the basic temperature may be 18 degrees Celsius.

[0120] In this step, when the regional temperature difference between the occupied area and the unoccupied area is detected to be less than the second threshold, a zonal air flow simulation is performed according to a preset simulation tool, and the zonal air flow simulation is used for zonal temperature control. Exemplarily, the second threshold may be 2 degrees Celsius.

[0123] In this step, a target scheme for the diffusion path of hot and cold air is generated according to the simulation result.

[0124] In step S302d, the operating parameters of the air conditioner are controlled according to the target scheme for the diffusion path of hot and cold air to maintain zonal temperature control.

[0125] In this step, the operating parameters of the air conditioner are controlled according to the target scheme for the diffusion path of hot and cold air to maintain zonal temperature control. Exemplarily, the operating parameters of the air conditioner may include at least one of wind speed, air deflector angle, compressor frequency, fan speed, and inner pipe temperature. In this way, through air flow simulation, the operating parameters and air deflector angle of the air conditioner can be adjusted to ensure that hot air and cold air diffuse along the optimal path, accurately send air to the target area, maintain the temperature of this zone within the target temperature range, reduce local overcooling or overheating phenomena, reduce excessive energy consumption, and achieve optimal energy consumption control while fully ensuring the comfort of personnel.
