Revolving speed controlling method for draught fan of air-conditioner

Abstract

The invention discloses a revolving speed controlling method for a draught fan of an air-conditioner. The method comprises the following steps: in a cooling mode, when [Delta]T is lower than or equalto T<1>, the operation revolving speed of the draught fan is lowered according to a first preset speed regulation rate; environment real-time noises are detected every other time cycle t, and when [Delta]D is less than or equal to D<00>, an environment real-time noise D in the time cycle is defined as an optimal noise value D<s> and the draught fan operates according to current revolving speed; and the difference between the environment real-time noise D and D<s> is compared in real time, so the revolving speed is timely adjusted. According to the revolving speed controlling method for the draught fan of the air-conditioner, the revolving speed of the draught fan of the air-conditioner is controlled based on temperature information and noise information in a certain cycle, and wind speed adjusting levels of the air-conditioner can be added; on the one hand, users' requirements for wind speed of the air-conditioner can be met, and on the other hand, the air-conditioner can operate in a low-noise status; and therefore, an operation status of the air-conditioner can be divided into a plurality of statuses, so the air-conditioner can satisfy multiple types of performance simultaneously.

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 adjusts 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. Mo...

[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
