It can be understood that in the case of powering on the air conditioner, the start is operated in an initial mode corresponding to the start command according to the received start command.
After the air conditioner is started in the initial mode operation, an outdoor ambient temperature is obtained by an outdoor temperature sensor provided to the outdoor unit. And after the air conditioner is started in the initial mode operation, acquiring the current motor power of an external fan of the air conditioner.
In step S200 of some embodiments, the current speed of the external fan of the air conditioner is determined by matching with a preset speed control table according to the outdoor environment temperature and the current motor power.

The method for determining T35/T43/T53 is as follows: T35/T43/T53 corresponds to nominal refrigeration condition (outdoor environment temperature is 35 ℃)/maximum refrigeration condition (outdoor environment temperature is 43 ℃)/high temperature refrigeration condition (outdoor environment temperature is 53 ℃), control voltage 264V (220V+20%) and the air conditioner external unit operates according to 110% load, the external fan reaches maximum rotation speed, the maximum power of motor operation is measured to be A (the motor power under default outdoor normal ring temperature, namely 35 ℃) and B (the motor power under outdoor environment temperature is higher, namely 43 ℃) and C (the motor power under outdoor severe ring temperature, namely 53 ℃) and the temperature of the external machine ring temperature sensor T35/T43/T53 at the moment, under the three conditions, the IPM temperature of the fan is required to be less than 90 ℃ (internal standard limit value)
A method of determining an outdoor ambient temperature, tm: under the high-temperature refrigeration working condition (when the outdoor environment temperature is 53 ℃), 264V (220V+20%) only operates the outdoor fan to operate at the highest rotation speed, and the temperature of the fan IPM reaches 90 ℃ by increasing the environment temperature (the environment temperature cannot exceed the highest use ring temperature marked by the external machine), the power value of the motor is D, and the temperature of the outdoor environment temperature sensor is Tm.
A method of determining motor power E: under the high-temperature refrigeration working condition (the outdoor environment temperature is 53 ℃), 264V (220V+20%) only operates the outdoor fan to operate at the highest rotating speed, the condition that the load of the dust accumulation fan of the outdoor unit is large is simulated through the newspaper heat blocking exchanger, and when the temperature of the test fan IPM reaches 90 ℃, the power value of the motor is measured to be E (limit power).
It should be noted that, the motor power: a is more than B and less than C and less than D and E, and outdoor environment temperature is higher than that of the water-based paint: t35< T43< T53< Tm.
Let the detected outdoor ambient temperature be Ta and the current motor power be Fw.
If Ta is less than or equal to T35, if Fw is less than or equal to A, the current rotating speed gear of the outer fan is normal.
If Ta is less than or equal to T35 and A is less than or equal to Fw is less than or equal to B, the current rotating speed gear of the outer fan is normal.
If Ta is less than or equal to T35 and B is less than or equal to Fw is less than or equal to C, the current rotating speed gear of the outer fan is normal.
If Ta is less than or equal to T35 and C is less than or equal to Fw is less than or equal to D, the current rotating speed gear of the outer fan is normal.
If D < Fw is less than or equal to E when Ta is less than or equal to T35, the current rotating speed gear of the external fan is abnormal, and a downshift is needed.
Similarly, when T35< Ta+.T43, fw+.A, the current rotation speed of the outer fan is normal.
When T35< Ta is less than or equal to T43, if A < Fw is less than or equal to B, the current rotating speed gear of the outer fan is normal.
When T35< Ta is less than or equal to T43, if B < Fw is less than or equal to C, the current rotating speed gear of the outer fan is normal.
When T35< Ta is less than or equal to T43, if C < Fw is less than or equal to D, the current rotating speed gear of the outer fan is normal.
When T35< Ta is less than or equal to T43, if D < Fw is less than or equal to E, the current rotation speed gear of the external fan is abnormal, and a downshift is needed.
Similarly, when T43< ta+.t53, if fw+.a, the current rotation speed of the external fan is normal.
When T43 is smaller than Ta and smaller than T53, if A is smaller than Fw and smaller than B, the current rotating speed gear of the outer fan is normal.
When T43 is smaller than Ta and smaller than T53, if B is smaller than Fw and smaller than C, the current rotating speed gear of the outer fan is normal.
When T43 is smaller than Ta and smaller than T53, if C is smaller than Fw and smaller than D, the current rotating speed gear of the outer fan is normal.
When T43< Ta +.T53, if D < Fw +.E, the current rotation speed gear of the outer fan is abnormal, and a downshift is needed.
Similarly, when T53 is smaller than Ta and smaller than Tm, if Fw is smaller than A, the current rotation speed of the outer fan is normal.
When T53 is smaller than Ta and smaller than Tm, if A is smaller than Fw and smaller than B, the current rotating speed gear of the outer fan is normal.
When T53 is smaller than Ta and smaller than Tm, if B is smaller than Fw and smaller than C, the current rotating speed gear of the outer fan is normal.
When T53 is smaller than Ta and smaller than Tm, if C is smaller than Fw and smaller than D, the current rotation speed gear of the outer fan is abnormal, and a downshift is needed.
Similarly, if fw+.A, then the current speed of the outer fan is normal when Tm < Ta.
And when Tm is smaller than Ta, if A is smaller than Fw and smaller than B, the current rotating speed gear of the external fan is normal.
If the Tm is smaller than Ta and the B is smaller than Fw and smaller than C, the current rotating speed gear of the external fan is abnormal, and a downshift is needed.
In step S300 of some embodiments, the external fan operation is controlled based on the current speed range.
It may be appreciated that after the step S200 is performed to match with a preset speed control table according to the outdoor environment temperature and the current motor power to determine the current speed of the external fan of the air conditioner, the specific performing steps may be: firstly, judging whether the current rotating speed gear of the external fan is the lowest rotating speed gear;
if yes, controlling the external fan to operate at the current rotating speed gear;
if not, the rotation speed gear is reduced to the current rotation speed gear until the current rotation speed gear is reduced to the target rotation speed gear;
and controlling the external fan to operate at the target rotating speed gear.
Further, as shown in fig. 2, the flow chart of the gear-down of the external fan provided by the application is that after the external fan meets the gear-down condition, firstly judging whether the current rotational speed gear of the external fan is the lowest rotational speed gear, if the current rotational speed gear is the lowest rotational speed gear, controlling the external fan to operate at the lowest rotational speed gear for 3 minutes, and then exiting the gear-down control program.
If the current rotating speed gear is judged not to be the lowest rotating speed gear, the method comprises the steps of executing control of the current rotating speed gear to reduce by 1 gear and operating for 3 minutes, judging whether the current rotating speed gear after gear reduction is normal or abnormal according to the rotating speed control table, if so, executing the step of judging whether the current rotating speed gear is abnormal, if so, executing the step of adding one gear to the current rotating speed gear, and after operating for 3 minutes, judging whether the current rotating speed gear is normal or not through the rotating speed control table, if so, judging whether the current rotating speed gear needs to be reduced again, and if so, executing the step of judging whether the current rotating speed gear is the lowest rotating speed gear. If the speed is normal, the speed is operated according to the target speed, and the speed can be operated for 5 minutes, namely the control speed-down program is exited.
In some embodiments of the application, after the step of controlling the external fan to operate at the target speed, the method includes:
under the condition that the outer fan is controlled to operate at the target rotating speed gear for a first preset time period, acquiring a gas pressure value of a refrigerant pipeline between the compressor and the evaporator;
comparing the gas pressure value with a preset pressure threshold value to obtain a pressure comparison result;
and adjusting the target rotating speed gear of the external fan according to the pressure comparison result.
It can be understood that, when the external fan is controlled to operate at the target speed for a first preset period of time, a gas pressure value M1 of a refrigerant pipeline between the compressor and the evaporator is obtained, so that a preset pressure threshold value is M2.
And comparing the gas pressure value M1 with a preset pressure threshold value M2 to obtain a pressure comparison result.
Controlling the target rotating speed gear of the external fan to be increased by one gear under the condition that the pressure comparison result indicates that the gas pressure value M1 is larger than the pressure threshold value M2;
and controlling the target rotating speed gear of the external fan to be reduced by one gear under the condition that the pressure comparison result indicates that the gas pressure value M1 is smaller than or equal to the pressure threshold value M2.
Therefore, the risk of damage to the compressor and the evaporator can be reduced, and the rotating speed of the external fan can be accurately controlled.
In some embodiments of the application, after the step of controlling the external fan to operate at the target speed, the method further comprises:
acquiring indoor environment temperature;
under the condition that the indoor environment temperature reaches a preset target temperature, starting timing to obtain a second holding time length;
and cleaning the outer fan under the condition that the second holding time period is longer than the first preset time period.
It can be understood that after the step of controlling the external fan to operate at the target rotation speed gear, the lower indoor environment temperature is acquired first, and when the indoor environment temperature reaches the target temperature, the timer is started to count time, so as to obtain a second keeping time, wherein the second keeping time refers to the time when the indoor environment temperature reaches the target temperature and begins to count time, and the target temperature is set according to the requirement of a user.
And comparing the second holding time with the first preset time, and cleaning the outer fan when the second holding time is longer than the first preset time.
In some embodiments of the present application, the self-cleaning the outer fan when the second holding time period is longer than the first preset time period includes:
detecting the temperature of the indoor coil pipe under the condition that the second holding time length is longer than the first preset time length;
comparing the indoor coil temperature with a preset coil temperature threshold;
and if the temperature of the indoor coil is greater than the temperature threshold of the coil, stopping the operation of the external fan, and controlling the air conditioner to enter a self-cleaning mode so as to perform self-cleaning on the external fan according to the self-cleaning mode.
It is understood that, in the case that the second holding time period is longer than the first preset time period, the indoor coil temperature is detected, the indoor coil temperature is compared with a preset coil temperature threshold value, and if the indoor coil temperature is greater than the coil temperature threshold value, the operation of the external fan is stopped.
