Problems solved by technology

When the direction of the natural wind is opposite to that of the external fan, it may cause resistance to the exhaust air from the outlet of the external fan. To the natural wind, resulting in an increase in the power of the air conditioner and higher power consumption
Therefore, the external fan control method of the existing air conditioner still has the problem of being easily affected by the external environment, resulting in high power consumption of the air conditioner.

Embodiment 1

[0035] This embodiment provides a method for controlling an outdoor fan, and the method can be applied to a controller in an outdoor fan of an air conditioner, see eg figure 1 As shown in the flow chart of the outdoor fan control method, the method mainly includes the following steps S102 to S106:

[0036] In step S102, it is detected whether there is an air outlet resistance at the air outlet of the outdoor fan.

[0037] The above-mentioned wind resistance can be determined by obtaining the wind direction of the natural wind and the wind direction of the outside fan. When the wind direction of the outside natural wind and the wind direction of the outside fan are opposite or form a certain angle, the natural wind will be discharged from the air outlet of the outside fan. The wind produces a certain wind resistance. In another embodiment, it is also possible to determine whether there is wind resistance at the air outlet of the outdoor fan by detecting the running current of ...

Embodiment 2

[0063] Corresponding to the outdoor fan control method provided in the above-mentioned first embodiment, the embodiment of the present invention provides an example of applying the above-mentioned outdoor fan control method to control the external fan. Figure 5 The shown flow chart of the control of the outdoor fan can be specifically executed with reference to the following steps S502 to S512:

[0064] Step S502: Use a current sensor to detect the running current of the motor of the outdoor fan.

[0065] Step S504: According to the running current of the motor, determine whether there is a reverse natural wind at the air outlet of the outdoor fan. If yes, go to step S506, if not, go to step S510.

[0066] When the motor running current of the outdoor fan has a sudden change, for example, when Ut-U(t-1)>>U(t-1)-U(t-2), that is, the current variation of the motor at time t Ut- When U(t-1) is much larger than the current variation U(t-1)-U(t-2) at time t-1, it can be determin...

Embodiment 3

[0073] Corresponding to the outdoor fan control method provided in the above-mentioned first embodiment, the embodiment of the present invention provides an outdoor fan control device, which can be applied to the controller in the outdoor fan. Image 6 The schematic structural diagram of the outdoor fan control device shown, the device includes:

[0074]The detection module 61 is used to detect whether there is wind resistance at the air outlet of the outdoor fan.

[0075] The first control module 62 is configured to control the outdoor fan to stop rotating when there is wind resistance at the air outlet of the outdoor fan, so that the natural wind generates air volume in the outdoor fan.

[0076] The second control module 63 is configured to acquire the air volume generated by the natural wind in the outdoor fan, and control the external fan according to the air volume generated by the natural wind.

[0077] In the above-mentioned outdoor fan control device provided in this ...

Abstract

The invention discloses an outdoor fan control method, a device, an air conditioner and a storage medium, and relates to the technical field of air conditioners. The above outdoor fan control method includes the following steps: detecting whether there is air outlet resistance at the air outlet of the outdoor fan; if so, controlling the external fan The fan stops rotating, so that the natural wind generates air volume in the outdoor fan; the air volume generated by the natural wind in the outdoor fan is obtained, and the external fan is controlled according to the air volume generated by the natural wind. The invention reduces the power consumption of the air conditioner by controlling the outside fan to stop rotating when the natural wind from the outside produces air resistance at the air outlet of the outside fan, and controls the outside fan according to the air volume generated by the natural wind.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, and in particular, to an outdoor fan control method, device, air conditioner and storage medium. Background technique [0002] With the development of air-conditioning technology, the application of air-conditioning is becoming more and more extensive. In practical applications, because the outdoor fan of the air conditioner is generally located in the outdoor environment, it is easily affected by the outdoor environment, especially the external natural wind. When the direction of the natural wind is opposite to that of the outside fan, it may cause resistance to the exhaust air at the air outlet of the outside fan. In order to achieve the heat exchange required by the air conditioner, the outside fan needs to increase the speed to provide a larger air volume to offset the reverse. To the natural wind, the power consumption of the air conditioner is increased, and the power cons...
