The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The throttling device expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

S2, the sensor detects user position information of all users within the sensor detection range.
And S3, the controller obtains the position information of the target user and the position information of the nearby user according to the position information of all users.
The controller calculates the distance between every two users according to the user position information, counts the number of the nearby users of each user, and obtains the user position information of the user with the largest number of the nearby users as the target user position information. The nearby users are users whose distance from the users is smaller than the set distance.
And S4, the controller controls the air outlet direction of the air deflector according to the position information of the target user and the position information of the user nearby the target user.
The scheme can further meet the requirements of most people.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
