Abstract

The invention discloses a control method for an outdoor draught fan of an air conditioner. The control method includes the steps that the first indoor temperature in an indoor area where the air conditioner is located is obtained; the outdoor draught fan is determined and controlled to run at a first outdoor unit air speed according to the first temperature difference value of the first indoor temperature and the target indoor temperature; the second indoor temperature of the indoor area after the set time period and the running frequency of a compressor are obtained; and the outdoor draught fan is determined and controlled to run at a second outdoor unit air speed according to the second temperature difference value of the second indoor temperature and the target indoor temperature and the running frequency. By means of the control method for the rotating speed of the outdoor draught fan of the air conditioner, accurate control over the air speed of the outdoor unit in the two statescan be achieved for the unstable state and the stable state of the air conditioner when the air conditioner is started, influences of the instantaneous pressure difference of a system on an air conditioner system are reduced, and the running stability of the system is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for controlling the speed of an outdoor fan of an air conditioner. Background technique [0002] In the existing air-conditioning products, whether it is a split type air conditioner or an integrated air conditioner, it includes two parts: the outdoor and the indoor. environment for heat exchange. In order to achieve a better heat exchange effect, in general, during the operation of the air conditioner, the speed of the different fans must be controlled. If the heat exchange needs to be accelerated, the speed of the fan can be increased, or when the heat exchange needs to be slowed down. , you can reduce the fan speed. Therefore, the change of the rotational speed of the fan can be directly related to the heating or cooling performance of the air conditioner. [0003] Among them, in the speed control method of the outdoor fan, especially when the f...
