The control method comprises the steps that the environment humidity is obtained; when the environment humidity is no greater than the sethumidity, an outer fan is started, and the speed of the outer fan is increased to the first target rotation speed; a compressor of the air conditioner is started while or before or after the speed ofthe outer fan starts to be increased; and the frequency of the compressor is continuously increased stage by stage according to multiple set speeds. By means of the control method, the frequency increase time of the compressor can be greatly shortened while normal oil return of the compressor is ensured, so that the purpose of quick heating is achieved, the comfort of the air conditioner is improved, and user experience is improved.

The invention relates to the technical field of air conditioning, in particular to an air conditioning control method and system under high-humidity heating conditions. The invention aims to solve the problems in the existing air conditioner start-up frequency increase control method that the rapid heating effect is poor due to the long frequency increase time, and the outdoor unit is easy to frost when the ambient humidity is high. For this purpose, the control method of the present invention includes: obtaining the ambient humidity; when the ambient humidity is greater than the set humidity, starting the external fan and raising the speed to the first target speed; Adjust the opening of the expansion valve to the first target opening; start the compressor when the external fan and the expansion valve reach the set conditions; make the compressor continuously increase in frequency in stages according to a plurality of frequency increasing speeds. The above setting method can greatly shorten the frequency increase time of the compressor while ensuring the normal oil return of the compressor, thereby achieving the purpose of rapid heating and delaying frosting, improving the comfort of the air conditioner and improving the user experience.
