<p>The present invention relates to an air-conditioner and its controlling method, especially three-stage operation for controlling two compressors, so as to improve application scope of refrigerating capacity and reduce power consumption. The present invention makes refrigerating capacity clear according to the operation method of compressor to opening air outlet separately. The present invention can prevent discharged air temperature from increasing by decreasing air discharge rate when decreasing refrigerating capacity caused by changing compressor operation method. In addition, the present invention changes the compressor operation method in order to increase and decrease refrigerating capacity to decrease air discharge rate, and open and close air outlet with a certain time difference, thus can decrease air discharged noise of air outlet. Therefore, the present invention provides an air-conditioner controlling method, the air-conditioner comprises at least a compressor capable of changing refrigerant capacity and multiple outlets and indoor fan, its controlling method is based on changeable refrigerant capacity to process multiple operation methods, in operation to judge whetherinputting operation method transform information, if inputting operation method transform information, then decreasing the speed of the said indoor fan, and opening or closing stipulated beforehand atleast a outlet according to operation method transformation.</p> |
