Step S02: and obtaining the altitude Y of the air conditioner corresponding to the power W 1.
The above arrangement has the advantages that: the invention mainly aims to reduce the resistance of the motor because the air density is reduced along with the increase of the altitude, so that the power consumed by the fan is changed along with the change of the altitude under the same fan rotating speed, and the altitude Y of the air conditioner corresponding to the power W 1 can be obtained by detecting the power W 1 consumed by the fan in the operation time of T 1 under the rated rotating speed. It should be noted that, after the motor power W 1 consumed by the fan in the operation duration of T 1 at the rated rotation speed is obtained, the altitude Y where the air conditioner is located is obtained by a corresponding relationship between the altitude corresponding to the motor power W 1 stored in the memory of the air conditioner by a person skilled in the art, or the power W 1 may be substituted into a fitting formula between the power W 1 stored in the memory and the altitude Y, so as to obtain a specific numerical value of the altitude Y.

Y=k 1X2-K2X+K3; wherein K 1、K2、K3 is a fitting coefficient, which are constants, and X is an elevation influence factor;
altitude impact factor x=w 2/W1; wherein W 2 is the power consumed by the fan at standard altitude in the T1 running time.
The invention mainly aims to reduce the resistance of a motor due to the fact that the air density is reduced along with the increase of the altitude, the power of a fan is changed along with the change of the altitude, after the air conditioner leaves a factory to a high-altitude area, the power consumed by an outdoor fan in the operation time of T 1 is W 1 under the rated rotation speed when the air conditioner is started for the first time, the power W 2 consumed by the fan in the operation time of T 1 is stored in the air conditioner when the air conditioner is at the standard altitude before the air conditioner is started, and the power W 2 consumed by the outdoor fan in the operation time of T 1 under the standard altitude is detected after the air conditioner assembly is completed, for example, during the test operation of the air conditioner, so that the altitude influence factor X can be obtained through calculation according to the power W 1 and W 2, and the altitude Y where the air conditioner is located can be obtained according to a altitude fitting formula. The altitude fitting formula is obtained by fitting multiple experimental data by a person skilled in the art. According to the invention, the self-contained outdoor fan of the air conditioner is adopted, the installation altitude of the air conditioner unit is calculated through software calculation, the altitude measurement can be realized under the condition that no additional device is added, and the detection cost of the altitude of the air conditioner is greatly reduced.

Step S14: when the fan running speed N 1 of the air conditioner at the altitude Y exceeds the maximum fan limit speed N m, the fan running speed of the air conditioner at the altitude Y is the maximum fan limit speed N m;
step S15: storing the data of the fan running rotating speed N 1 of the air conditioner at the altitude Y;
Step S16: reducing the maximum input power of the air conditioner to obtain the maximum input power of the air conditioner at the altitude Y;
step S17: and storing the data of the maximum input power of the air conditioner at the altitude Y.
After the altitude Y of the air conditioner is obtained through calculation, the fan operation rotating speed N 1 corresponding to the altitude Y can be obtained through a formula or other modes, when the calculated fan operation rotating speed N 1 exceeds the maximum fan limit rotating speed N m, the operation rotating speed of the outdoor fan of the air conditioner is the maximum fan limit rotating speed N m when the altitude Y is obtained, the outdoor fan of the air conditioner is not only used for exchanging heat for a heat exchanger of an air conditioner refrigerant circulation system, but also used for radiating heat of an electric device in an electric cabinet body, the fan operation rotating speed N 1 of the air conditioner when the altitude Y exceeds the maximum limit operation rotating speed N m can only operate according to the maximum fan limit rotating speed N m, the air quantity is insufficient for normally radiating heat of the electric device, so that the electric device in the electric cabinet can not have good radiating effect, the condition that the heating value exceeds the limit is avoided, the damage caused by high-temperature heating of the electric device is avoided, when the air quantity of the outdoor fan is insufficient, the maximum input power of the air conditioner is reduced, the damage caused by the fact that the heating value of the electric device is too high, the reliability is ensured, the heating value of the electric device is reduced, the electric device can not be ensured to be input into the air conditioner, and the safe device is ensured, and the heat value is not to be input into the air conditioner.
Referring to fig. 3, step S13 further includes:
Step S131: substituting the altitude Y into a first linear function formula preset in the air conditioner to obtain the fan running rotating speed N 1 of the air conditioner at the altitude Y; the first linear function formula is a linear function formula between the altitude Y and the running rotating speed N 1 of the fan;
The first linear function formula is specifically: n 1＝P1*Y+P2; wherein, P 1、P2 is respectively a constant;
After the altitude Y of the air conditioner is obtained, the running rotating speed N 1 of the fan of the air conditioner at the altitude Y can be obtained through a first linear function formula stored in an air conditioner memory, wherein the first linear function formula is calculated by a plurality of times of experimental data by a person skilled in the art, and the higher the altitude is, the thinner the air is, the smaller the air resistance is, but the air quantity of the fan at the same rotating speed is correspondingly reduced due to the rarefaction of the air, and the rotating speed of the fan is required to be increased when the altitude is increased.
Referring to fig. 3, step S16 further includes:
Step S161: calculating a difference value N between a fan running rotating speed N 1 and a maximum fan limit rotating speed N m of the air conditioner at the altitude Y;
Step S162: substituting a difference value N between a fan running rotating speed N 1 and a maximum fan limit rotating speed N m of the air conditioner at the altitude Y into a second linear function formula preset in the air conditioner to obtain pre-reduced input power W 3; the second linear function formula is a linear function formula between the difference value between the fan rotating speed and the maximum fan limiting value rotating speed when the air conditioner is at the altitude Y and the pre-reduced input power;
The second linear function formula is specifically: w 3＝Q1*N+Q2; wherein, Q 1、Q2 is respectively a constant;
Step S163: and reducing the maximum input power of the air conditioner at the standard altitude by W 3 to obtain the maximum input power of the air conditioner at the altitude Y.
When the fan running rotating speed N 1 of the air conditioner at the altitude Y exceeds the maximum fan limiting rotating speed N m, the air conditioner can only run according to the maximum fan limiting rotating speed N m, so that the problem that the heat dissipation effect is poor when the fan dissipates heat for an electric device can be caused, the heating value of the electric device is reduced by reducing the maximum input power of the air conditioner, and the risk of overheating of the electric device is reduced. Specifically, the difference between the fan running speed N 1 and the maximum fan limit speed N m is substituted into a second linear function formula, so that the power value W 3 required to be reduced of the air conditioner can be obtained, the second linear function formula is obtained by multiple experimental data calculation by a person skilled in the art, and the maximum input power of the air conditioner at the altitude Y is obtained after the maximum input power of the air conditioner at the standard altitude is reduced by W 3.
It should be noted that, the maximum input power of the air conditioner at the altitude Y can also be obtained by:
the maximum input power of the air conditioner at standard altitude is multiplied by the altitude impact factor X.
The maximum input power of the air conditioner at the altitude Y is reduced in proportion to the maximum input power at the standard altitude Y, so that the maximum input power of the air conditioner at the altitude Y is calculated.
The fan operating speed N 1 of the air conditioner at altitude Y can also be obtained by:
the fan operating speed at standard altitude for the air conditioner is divided by the altitude impact factor X.
The fan operation rotation speed of the air conditioner at the altitude Y is increased in proportion to the fan operation rotation speed at the standard altitude Y, so that the fan operation rotation speed N 1 of the air conditioner at the altitude Y is calculated.
Or in another embodiment, the maximum input power of the air conditioner at the altitude Y and the fan operation rotation speed N 1 of the air conditioner at the altitude Y can be obtained by the following steps:
and directly obtaining the corresponding maximum input power and the corresponding fan operation rotating speed according to the altitude Y of the air conditioner.
