[0027] The method for controlling an air conditioner provided in the embodiment of the present disclosure is applied to an air conditioner. Determine the operating mode of the air conditioner. Obtain the indoor ambient temperature, the target air outlet temperature, and the fan speed of the indoor fan, and then control the compressor frequency of the air conditioner according to the operating mode, the indoor ambient temperature, the target air outlet temperature, and the fan speed of the indoor fan. In this way, the air outlet temperature is adjusted according to the indoor ambient temperature and the target air outlet temperature, so that the air conditioner blows air at the target air outlet temperature, which will not change with the change of the indoor ambient temperature, thereby achieving a constant air outlet temperature, thereby improving the user experience of using the air conditioner.

[0028] Combination Figure 1 As shown, the embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:

[0029] In step S101, the air conditioner determines an operation mode of the air conditioner.

[0030] Step S102, the air conditioner obtains the indoor ambient temperature, the target air outlet temperature and the fan speed of the indoor fan.

[0031] Step S103, the air conditioner controls the compressor frequency of the air conditioner according to the operation mode, the indoor ambient temperature, the target air outlet temperature and the fan speed of the indoor fan to keep the air outlet temperature constant.

[0032] The method for controlling an air conditioner provided by the embodiment of the present disclosure is adopted to determine the operation mode of the air conditioner, obtain the indoor ambient temperature, the target air outlet temperature and the fan speed of the indoor fan, and then control the compressor frequency of the air conditioner according to the operation mode, the indoor ambient temperature, the target air outlet temperature and the fan speed of the indoor fan. In this way, under different operation modes and fan speeds, the air outlet temperature is adjusted according to the indoor ambient temperature and the target air outlet temperature, so that the air conditioner blows air at the target air outlet temperature, which will not change with the change of the indoor ambient temperature, and the constant air outlet temperature is achieved, thereby improving the user experience of using the air conditioner.

[0033] In some embodiments, during cooling, in order to adjust the indoor ambient temperature to the indoor temperature preset by the user, the air outlet temperature of the air conditioner will be lower than the indoor temperature preset by the user, which may easily make the user colder. During heating, in order to adjust the indoor ambient temperature to the indoor temperature preset by the user, the air outlet temperature of the air conditioner will be higher than the indoor temperature preset by the user, which may easily make the user hotter. As the difference between the indoor ambient temperature and the indoor temperature preset by the user becomes smaller and smaller, the compressor frequency will become lower and lower, resulting in lower and lower air outlet temperature. This makes it easy for users to get sick due to the large temperature difference of the air outlet temperature of the air conditioner. However, in the case of different operating modes and fan speeds, the air outlet temperature is adjusted according to the indoor ambient temperature and the target air outlet temperature, so that the air conditioner blows at the target air outlet temperature, which will not change with the change of the indoor ambient temperature, and the constant air outlet temperature is achieved, so that the user's air conditioner can blow out the air outlet temperature that the user wants, thereby improving the user's experience of using the air conditioner.

[0034] Further, the operation mode includes a shower wind mode or a cool blowing mode. In some embodiments, the shower wind mode is a heating mode, and the target air outlet temperature is between 40 degrees Celsius and 56 degrees Celsius. The cool blowing mode is a cooling mode. The target air outlet temperature is between 10 degrees Celsius and -26 degrees Celsius.

[0035] In some embodiments, the wind speed set by the user is high wind, that is, the fan speed of the indoor fan is 1000rpm (Revolutions Per Minute). The user sets the air outlet temperature at 50°C. Due to the limitations of the air conditioner device itself, the air outlet temperature cannot reach 50°C when the wind speed is high. In order to meet the user's temperature requirements, the air conditioner sets the fan speed to 800rpm, so that the air outlet temperature is 50°C.

[0036] In some embodiments, the wind speed set by the user is high wind, that is, the fan speed of the indoor fan is 1000rpm. The user sets the outlet air temperature at 50°C. Due to the limitation of the air conditioner device itself, the outlet air temperature cannot reach 50°C when the wind speed is high. In order to meet the user's demand for wind speed, the air conditioner sets the fan speed to 1000rpm without considering the outlet air temperature.

[0037] Optionally, the air conditioner controls the compressor frequency of the air conditioner according to the operation mode, the indoor ambient temperature, the target air outlet temperature and the fan speed of the indoor fan, including: the air conditioner obtains a first temperature difference according to the indoor ambient temperature and the target air outlet temperature. The air conditioner obtains the operation frequency of the compressor according to the operation mode, the target air outlet temperature, the first temperature difference and the fan speed. The air conditioner sets the compressor frequency of the air conditioner as the operation frequency. In this way, the compressor frequency can be adjusted according to the first temperature difference between the indoor ambient temperature and the target air outlet temperature, so that the air outlet temperature can reach the target air outlet temperature, and the constant air outlet temperature is achieved, thereby improving the user experience of using the air conditioner.

[0038] Optionally, the air conditioner obtains a first temperature difference according to the indoor ambient temperature and the target air outlet temperature, including: the air conditioner determines the difference between the indoor ambient temperature and the target air outlet temperature as the first temperature difference.

[0039] Optionally, the air conditioner obtains the operating frequency of the compressor according to the operating mode, the target outlet air temperature, the first temperature difference and the fan speed, including: the air conditioner obtains a first temperature compensation value corresponding to the first temperature difference according to the operating mode. The air conditioner obtains a second temperature compensation value corresponding to the fan speed according to the operating mode. The air conditioner obtains the operating frequency of the compressor according to the target outlet air temperature, the first temperature compensation value and the second temperature compensation value. In this way, the operating frequency of the compressor is obtained by the target outlet air temperature, the first temperature compensation value corresponding to the first temperature difference and the second temperature compensation value corresponding to the fan speed, so that under the operating frequency, the fan speed and the first temperature compensation value, the outlet air temperature of the air conditioner can be the same as the target outlet air temperature, thereby improving the user experience of using the air conditioner.

[0040] Further, the air conditioner obtains the first temperature compensation value corresponding to the first temperature difference according to the operating mode, including: the air conditioner obtains the first temperature difference threshold, the third temperature compensation value, the second temperature difference threshold, the fourth temperature compensation value and the fifth temperature compensation value corresponding to the operating mode. When the first temperature difference is less than the first temperature difference threshold, the third temperature compensation value is determined as the first temperature compensation value. When the first temperature difference is greater than or equal to the first temperature difference threshold and the first temperature difference is less than the second temperature difference threshold, the fourth temperature compensation value is determined as the first temperature compensation value. When the first temperature difference is greater than or equal to the second temperature difference threshold, the fifth temperature compensation value is determined as the first temperature compensation value. In some embodiments, the operating mode is a bath wind mode. The first temperature difference threshold is 5°C. The third temperature compensation value is 5°C. The second temperature difference threshold is 10°C. The fourth temperature compensation value is 8°C. The fifth temperature compensation value is 10°C.

[0041] Further, the air conditioner obtains a first temperature compensation value corresponding to the first temperature difference according to the operation mode, including: the air conditioner obtains a first temperature compensation database corresponding to the operation mode. The first temperature compensation database stores the correspondence between the first temperature difference and the first temperature compensation value. The air conditioner uses the first temperature compensation database to perform a table lookup operation on the first temperature difference to obtain the first temperature compensation value corresponding to the first temperature difference.

[0042] Further, the air conditioner obtains a second temperature compensation value corresponding to the fan speed according to the operation mode, including: the air conditioner obtains a second temperature compensation database corresponding to the operation mode. The second temperature compensation database stores the correspondence between the fan speed and the second temperature compensation value. The air conditioner uses the second temperature compensation database to look up the fan speed and obtain the second temperature compensation value corresponding to the fan speed. In some embodiments, when the operation mode is the bath wind mode, the user sets it to high wind, and the fan speed is 1000rpm. In the second temperature compensation database corresponding to the bath wind mode, the fan speed 1000rpm is looked up in the table, and the second temperature compensation value obtained is 5°C. In some embodiments, when the operation mode is the bath wind mode, the user sets it to medium wind, and the fan speed is 800rpm. In the second temperature compensation database corresponding to the bath wind mode, the fan speed 800rpm is looked up in the table, and the second temperature compensation value obtained is 3°C.

The air conditioner obtains the actual inner coil temperature. The air conditioner determines the difference between the first target inner coil temperature and the actual inner coil temperature as the second temperature difference. The air conditioner obtains the operating frequency of the compressor according to the second temperature difference using a PID (Proportion Integral Differential) algorithm. In this way, by using the PID algorithm to obtain the operating frequency of the compressor according to the second temperature difference, when the air conditioner is running at this operating frequency, the actual inner coil temperature will be the same as the first target inner coil temperature, so that the outlet air temperature of the air conditioner is the same as the target outlet air temperature, thereby improving the user experience of using the air conditioner.

[0044] Further, the air conditioner uses a preset first algorithm to obtain a first target inner coil temperature according to the target outlet air temperature, the first temperature compensation value and the second temperature compensation value, including: when the operation mode is the shower wind mode, the air conditioner calculates T 1p =T CF +T WC +T FS , obtain the first target internal coil temperature.
