Embodiment Construction

[0026] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0027] In one embodiment, as figure 1 As shown, a fan speed control method is provided, the method includes the following steps:

[0028] S200. Obtain the current working state of the fan. Wherein, the working state of the fan includes a starting state and a running state.

[0029] Specifically, the fan is connected to the main controller through the driver during the working process. The driver is used to drive the fan to run, and the main controller is used as a data processing unit to process various status data of the fan. The driver is an intermediate device, which ...

Abstract

The invention relates to a draught fan rotating speed control method and device, an air conditioner outdoor unit device and air conditioning equipment. The method comprises the steps that the currentworking state of a draught fan is obtained, and the working state of the draught fan comprises a starting state and an operating state; when the current working state of the draught fan is the starting state, a target rotating speed feedback signal is generated and sent to a main controller so as to obtain a speed adjusting signal generated by the main controller according to the target rotating speed feedback signal; the rotating speed of the draught fan is adjusted according to the speed adjusting signal so as to enable the draught fan to enter the operating state; when the draught fan enters the operating state, a real-time rotating speed feedback signal is generated and sent to the main controller, so that a speed stabilizing signal generated by the main controller according to the real-time rotating speed feedback signal is obtained; and the real-time rotating speed of the draught fan is adjusted according to the speed stabilizing signal.

Description

technical field [0001] The present application relates to the technical field of air-conditioning equipment, in particular to a fan speed control method and device, an air-conditioning external unit, and air-conditioning equipment. Background technique [0002] When the air conditioner is working, it needs to control the speed of the fan to achieve the purpose of heating or cooling. The traditional fan control method mainly realizes the control of the fan speed through the exchange of fan speed information between the main control board and the drive board, that is, The main control board adjusts the speed of the fan in real time according to the system status, and converts the target speed into a voltage and sends it to the drive board. Feedback to the main control board, the main control board judges the real-time speed of the fan according to the speed pulse. [0003] In the traditional fan control mode, when the fan starts up, for example, when the fan recovers from a f...
