Embodiment Construction
[0019] In the following, the present invention will be specifically described through exemplary embodiments. It should be understood, however, that elements, structures and characteristics of one embodiment may be beneficially incorporated in other embodiments without further recitation.
[0020] The invention provides a method for controlling the motor speed of an air conditioner. The method for controlling the motor speed of an air conditioner includes the following steps:
[0021] S0: By inputting the difference ΔT between the indoor temperature and the set temperature, output the fan speed U through fuzzy calculation; in this step, specifically: calculate the difference between the indoor temperature and the operating set temperature; fuzzify the temperature difference as fuzzy The input quantity, according to the preset fuzzy membership function, obtains the fuzzy membership degree F through fuzzy calculation; according to the preset fuzzy membership function, the output ...

The invention provides a control method for the rotating speed of an air conditioner motor. The control method for the rotating speed of the air conditioner motor comprises the following steps that S0, the rotating speed U of a draught fan is output through fuzzy computing by inputting the difference value of the indoor temperature and the set temperature; S1, the correction factor K is output through fuzzy computing by inputting the indoor temperature; and S2, the final rotating speed S of the draught fan is obtained through computing according to the rotating speed U of the draught fan and the correction factor K, wherein S is equal to U*K. By means of the control method, due to a direct current fan motor fuzzy control algorithm, intelligence of speed regulating of a direct current motoris achieved, smooth stepless speed adjusting of the fan motor can be achieved according to environment changes, and energy waste caused by rotating speed changing conducted through an EEPROM each time and rotating speed jumping are avoided.
Description
technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to a method for controlling the rotational speed of an air conditioner motor. Background technique [0002] At present, air-conditioning indoor units are installed in the living environment, and all operations of air-conditioning indoor units will directly affect people's living environment, especially noise and air volume. The noise generated by the indoor unit of the air conditioner is generally related to the structure of the machine and the inherent properties of the components themselves, while the size of the air blown by the air conditioner can be controlled artificially. Some air conditioners have high wind speed and long distance, while others have low wind speed and short distance. Sudden changes in air volume and wind speed will affect comfort, and a criterion for measuring the performance of air conditioners is human subjective experience. [0003] Chinese in...
