The invention discloses a control method and device for an outdoor draught fan in a splitting type air conditioner. The method comprises the following steps of detecting an outdoor environment temperature and an outdoor condenser coiled pipe temprature, and obtaining an operation state of an air conditioner; when the air conditioner is at a refrigeration operation state, judging whether the outdoor environment temperature is lower than a low-temperature refrigeration function starting threshold value or not; if so, controlling the outdoor draught fan to be started and operates at a first operation gear when the outdoor condenser coiled pipe temprature is greater than or equal to the low-temperature refrigeration function starting threshold value; if judging that the outdoor environment temperature is larger than or equal to the low-temperature refrigeration function starting threshold value, determining the operation gear of the outdoor draught fan according to the outdoor environment temperature. According to the control method, the rotary speed of the outdoor draught fan is controlled by the outdoor environment temperature and the outdoor condenser coiled pipe temprature, so that the outdoor direct-current fraught fan adopts different rotary speeds under different working conditions; the environment adaptability of the whole machine is improved and the season energy efficiency of the whole machine can be improved.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for controlling an outdoor fan in a split air conditioner. Background technique [0002] At present, the market has higher and higher requirements for the energy efficiency of air conditioners, and the energy efficiency development potential of fixed-frequency air conditioners is getting lower and lower. Therefore, many split-type fixed-frequency air conditioners currently use DC external motors for external heat exchange. However, at present, most of the fixed-frequency air conditioners that use DC external motors have relatively simple control methods for their outdoor fans. conditions and make the air conditioner less energy efficient. Contents of the invention [0003] The object of the present invention is to solve one of the above-mentioned technical problems at least to a certain extent. [0004] Therefore, the first object of the present i...
