The invention discloses a control method for an outdoor fan in an air conditioner. The control method comprises the following steps of detecting pipe coil temperature of the outdoor fan in real time when the air conditioner runs in a cooling mode; judging a variation trend of the pipe coil temperature; if the pipe coil temperature is determined to be in a reduction trend, reducing rotating speed of the outdoor fan according to the pipe coil temperature; if the pipe coil temperature is determined to be in a rising trend, increasing the rotating speed of the outdoor fan according to the pipe coil temperature. According to the control method for the outdoor fan, the pipe coil temperature of the outdoor fan and the rotating speed of the outdoor fan are linked, and the rotating speed of the outdoor fan is reduced when the pipe coil temperature is lower, so that the air conditioner can run stably and reliably (particularly when outdoor temperature is lower). The invention also discloses a control device for the outdoor fan in the air conditioner and the air conditioner with the control device.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a method for controlling an outdoor fan in an air conditioner, a control device for an outdoor fan in an air conditioner, and an air conditioner with the control device. Background technique [0002] The current air-conditioning system, such as conventional household inverter air conditioners, has an outdoor ambient temperature above 8°C when cooling, and when the outdoor ambient temperature is lower than 8°C, because the overall pressure of the air conditioner is too low, it is easy to cause the evaporator of the indoor unit to freeze , blowing water and other phenomena, and the problem of difficult oil return from the compressor of the outdoor unit. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. Therefore, an object of the present invention is ...
