Air conditioner fan speed control method

Abstract

The invention discloses a fan speed control method of an air conditioner, which comprises the following steps: in cooling mode, when ΔT≤T 1 When ΔD i ≤D 00 When , set the optimal noise value of the real-time noise of the environment in this time period to D s , the fan runs at the current speed; compare the real-time noise of the environment in real time D i with D s The difference in order to adjust the speed in time. According to the fan speed control method of the present invention, according to the temperature information and noise information within a certain period, the rotation speed of the fan of the air conditioner is controlled, and the wind speed adjustment level of the air conditioner can be increased. On the one hand, it can meet the user's wind speed requirements for the air conditioner. On the other hand, the air conditioner can also be operated in a low-noise state, so that the operating state of the air conditioner can be subdivided into multiple states, so that the air conditioner can satisfy multiple performances at the same time.

Description

technical field [0001] The invention relates to the technical field of air conditioning equipment, in particular to a method for controlling the speed of a fan of an air conditioner. Background technique [0002] The motor of the air conditioner is basically set to several gears according to the experimental conditions. In actual use, the speed is automatically adjusted according to the set scene or the user can adjust the speed according to their own needs. There are obvious deficiencies in this speed control method: [0003] First, the several speeds set in the laboratory cannot well cover the air supply requirements of users in actual use; [0004] Second, when the user adjusts the speed, one of the main considerations is that the operation noise is too loud, so the speed is adjusted to the lowest gear. Too low speed is not conducive to the heat exchange effect of the air conditioner, resulting in poor cooling effect, high energy consumption, and high electricity bills. ...

[0003] First, the several speeds set in the laboratory cannot well cover the air supply requirements of users in actual use;

[0004] Second, when the user adjusts the speed, one of the main considerations is that the operation noise is too loud, so the speed is adjusted to the lowest gear. Too low speed is not conducive to the heat exchange effect of the air conditioner, resulting in poor cooling effect, high energy consumption, and high electricity bills. problems, and these problems cannot be displayed intuitively on site, and it is difficult for the user to know the background action of the air conditioner when adjusting the speed
