Problems solved by technology
[0003] However, although the speed of the external motor can be better adjusted in the test mode to achieve the purpose of reducing power and improving energy efficiency, there may be a change in the standard that requires the cancellation of the test mode
In the free-frequency operation mode, the speed of the external motor is extensive, and the connection with the air-conditioning system is not established. The speed is adjusted only according to the external ambient temperature, which consumes power in actual operation.

Embodiment Construction
[0068] In order to make the above objects, features, and advantages of the present invention, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0069] A power-based motor speed control method, such as figure 1 As shown, the method includes:
[0070] S1: boot.
[0071] S2: The air conditioner operates at the highest speed.
[0072] S3: The air conditioner controller judges whether or not the instant power value P1 is maintained within a preset range.
[0073] Specifically, the air conditioner controller determines whether or not the instant power value P1 remains unchanged. If it is, it is determined that the air conditioner operation is stable, then S4 is executed, and if it is continued, S3 is continued.
[0074] Specifically, the empty tone controller detects that the air conditioner voltage, current, storage, and read modules perform storage and reading, calculating the product, calculating the pro...

The present invention provides a motor speed reduction control method based on power, which includes: starting up; the air conditioner external unit runs at the highest speed; To execute the deceleration action, the air conditioner controller judges whether the currently obtained motor speed power value P2 is smaller than the previously obtained power value P2 before the motor speed change, and if so, the external motor speed continues to decrease until the next obtained power value before the motor speed change If P2 does not decrease any more, or the speed of the external motor drops to the minimum speed, the speed of the external motor stops decreasing and the current speed remains unchanged. The invention has the following beneficial effects: the rotational speed of the motor is correlated with the real-time power of the air conditioner, and the rotational speed of the external motor is provided according to the real-time power of the air conditioner, so as to reduce power and improve energy efficiency.
Description
Technical field [0001] The present invention relates to the field of air conditioning techniques, and in particular, there is a power-based motor drowning, a speed and speed automatic control method and an air conditioner. Background technique [0002] At present, there are two modes of air conditioning external motor motor speed control, namely, test mode and free-frequency operation mode, in which the speed of the outer unit is fixed; in the free-frequency operation mode, the air conditioner is based on the external ambient temperature. The interval corresponds to high high school low three-speed or high school speed run. For example, the invention of the disclosure number CN 105757902B discloses a method of air-conditioning outdoor fan speed control, by obtaining the outdoor ambient temperature value and the target temperature value in the cooling mode, calculating the outdoor ambient temperature value and the interior Temperature difference between the target temperature valu...
