The invention discloses a method for controlling a rotation speed of an outdoor fan of an air conditioner. The method includes: under a refrigeration mode, acquiring an outdoor environmental temperature value and an indoor set target temperature value, and calculating a temperature difference value between the outdoor environmental temperature value and the indoor set target temperature value; according to a temperature difference range of the temperature difference value, searching a corresponding fan operation mode from a preset corresponding relation between temperature difference ranges and fan operation modes; controlling the outdoor fan of the air conditioner to operate according to the searched fan operation mode. The invention further discloses a device for controlling the rotation speed of the outdoor fan of the air conditioner. The method and the device for controlling the rotation speed of the outdoor fan of the air conditioner have the advantages that operation efficiency of the air conditioner is improved, energy consumption and noise pollution in operation of the air conditioner is reduced, and accordingly comfort in use of the air conditioner is promoted for users; in addition, when the outdoor environmental temperature is high, the air conditioner can also operate for a long time to quickly cool indoors to a target low temperature.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method and device for controlling the speed of an outdoor fan of an air conditioner. Background technique [0002] Existing inverter air conditioner outdoor unit fans only have three speed gears: high, medium and low. In the cooling mode, the air conditioner selects the corresponding speed gear according to the outdoor ambient temperature. For example, when the outdoor temperature is high, the fan speed is adjusted to high. Speed gear; when the outdoor ambient temperature is moderate, adjust the fan speed to the middle speed gear; when the outdoor ambient temperature is low, adjust the fan speed to the low speed gear. [0003] With this existing method, when the outdoor temperature is high, the speed of the outdoor fan of the air conditioner is adjusted to a high speed gear, and the heat exchanger still cannot achieve sufficient heat dissipation, and it takes a long ...
