Therefore, the local atmospheric pressure of the place where the air conditioner is located is obtained through measurement of the air pressure measuring device, the measuring mode is simple and convenient, and the accuracy of the measuring result is good.
The second mode is as follows: local atmospheric pressure is estimated according to local altitude.
Another process of obtaining the local atmospheric pressure at the air-conditioning site in step S110 will be further described with reference to fig. 2.
And step S210, acquiring the local altitude of the place where the air conditioner is located, wherein the local altitude is obtained by positioning through the communication module.

For example: through intelligent control, the air conditioners with different altitudes have the same refrigerating/heating effect, and the problem that the air conditioners are not suitable for water and soil caused by different altitudes is solved.
Therefore, the air conditioners with different altitudes have the same refrigerating/heating effect by compensating the corresponding air volume difference according to the pressure difference of the local atmospheric pressure and the standard atmospheric pressure, so that the air conditioners can run more stably, the comfort of users is improved, and the application range of the air conditioners is wider.
In an optional example, the compensating for the air volume difference of the air conditioner due to the pressure difference in step S130 may include: if the pressure difference value is less than 0, increasing the current output air volume of an outdoor fan of the air conditioner by the air volume difference value corresponding to the pressure difference value; if the pressure difference value is larger than 0, reducing the current output air volume of the outdoor fan of the air conditioner by the air volume difference value corresponding to the pressure difference value.
For example: the intelligent monitoring control is used, the altitude at which the unit is installed is positioned through an intelligent module of the unit, the air quantity attenuation caused by the reduction of the air density is automatically compensated, if the local atmospheric pressure is detected to be lower than the standard atmospheric pressure, the air quantity lacking in the air conditioner outdoor unit is automatically compensated, and if the local atmospheric pressure is detected to be higher than the standard atmospheric pressure, the air conditioner outdoor unit automatically reduces a part of air quantity.

When the air conditioner operates under the non-standard atmospheric pressure, the frequency of the outdoor fan is equal to the operating frequency of the outdoor fan under the standard atmospheric pressure plus the corrected operating frequency.

Therefore, the local atmospheric pressure of the place where the air conditioner is located is obtained through measurement of the air pressure measuring device, the measuring mode is simple and convenient, and the accuracy of the measuring result is good.
The second mode is as follows: and acquiring the local atmospheric pressure of the place where the air conditioner is located, which is measured by the air pressure measuring device. The method comprises the following specific steps:
and acquiring the local altitude of the place where the air conditioner is located, which is obtained by positioning through the communication module. The specific functions and processes of the acquisition unit 102 are also referred to in step S210.
