Detailed Description
In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 schematically shows a flowchart of an air conditioner control method according to an embodiment of the present invention, and referring to fig. 1, the method may include operations S101 to S103, for example.
S101, acquiring the external environment temperature.
The ambient temperature may be, for example, an ambient temperature in a room, and may be detected by installing a temperature detection device in the air conditioner, or may be detected by installing a separate temperature detection device in the room, and then sending the detected temperature value to the control processing module of the air conditioner. The temperature detecting device may be, for example, a temperature sensor, and the present invention is not limited thereto.
In one possible way of this embodiment, when the air conditioner is in cooling operation, the ambient temperature in the room is obtained.
And S102, setting the initial target evaporation temperature of the air conditioner according to the ambient temperature.
The ambient temperature in the room changes along with the change of time, and the operation of the compressor of the inverter air conditioner is also influenced by the change of the ambient temperature. For example, when the air conditioner is just started in the air conditioning process, because the temperature of a room is far higher than the set temperature, the operating frequency of the air conditioner compressor is high, the output capacity of the air conditioner compressor is high so as to reach the set temperature, and when the set temperature is reached, the output capacity of the air conditioner compressor is reduced or stopped. The time from the actual temperature of the room to the set temperature affects the user experience, and the shorter the time, the better the user experience.
In order to enable the room to reach the expected temperature of the user more quickly, reduce the waiting time of the user and improve the comfort, in a feasible manner of the embodiment, the initial target evaporation temperature of the air conditioner can be set according to the actually acquired ambient temperature. Meanwhile, different evaporation temperatures are preset according to different outer ring temperatures, so that invalid frequency points of the compressor can be reduced, and energy is saved.
And S103, determining final target evaporation temperatures respectively corresponding to different wind gears of the indoor unit of the air conditioner according to the initial target evaporation temperatures, wherein the lower the wind gear is, the lower the corresponding final target evaporation temperature is. .
Because of the high, middle and low wind volume V of the air conditioner indoor unit1、V2、V3And different, the heat exchange quantity obtained by calculation according to the wind speed is sequentially decreased progressively. Therefore, the set final target evaporation temperatures corresponding to the high, medium and low grade winds are also gradually decreased, that is, the lower the wind grade is, the lower the corresponding final target evaporation temperature is, the final target evaporation temperature corresponding to the high grade wind is greater than the final target evaporation temperature corresponding to the medium grade wind, and the final target evaporation temperature corresponding to the medium grade wind is greater than the final target evaporation temperature corresponding to the low grade wind. In a feasible manner of this embodiment, since the temperature sensor is installed in the evaporator of the air conditioner, and the outlet air temperature of the air conditioner has a direct relationship with the inner tray temperature, the outlet air temperature can be ignored when calculating the heat exchange amount, and the heat exchange amount can be directly calculated according to the wind speed.
In this embodiment, based on the initial target evaporating temperature preset according to the ambient temperature, the final target evaporating temperature corresponding to the initial target evaporating temperature is set according to different wind speeds, so that the air conditioner outputs the same capacity under different wind gears, the set temperature does not need to be changed, and the actual experience of a user is improved.

The first target evaporation temperature is reasonably designed according to actual use requirements and the type of the air conditioner. In this embodiment, the first target evaporation temperature is optimized through a plurality of tests, and preferably, the range of the first target evaporation temperature may be, for example, 0 to 20 ℃, so that the method of this embodiment can be applied to different air conditioner types, and the practical range is wider.
S203, the initial target evaporation temperature is set to the second target evaporation temperature.
The second target evaporation temperature is reasonably designed according to actual use requirements and the type of the air conditioner. In this embodiment, the first target evaporation temperature is optimized through a plurality of tests, and preferably, the range of the first target evaporation temperature may be, for example, 3 to 23 ℃, so that the method of this embodiment can be applied to different air conditioner types, and the practical range is wider.
