According to the air conditioner and the control method thereof, a middle air supplementing structure is introduced into a compressor system, when the air conditioner is in a low-temperature heating mode, an electromagnetic valve is started, so that a refrigerant flows out of a compressor, passes through an indoor heat exchanger and then flows into a flash tank from an inlet of the flash tank; one path of liquid refrigerant flows out of a first outlet of the flash tank and flows into the outdoor heat exchanger for heat exchange, and the other path of gaseous refrigerant flows out of a second outlet of the flash tank and flows into the compressor after passing through the electromagnetic valve, so that pressurization operation is performed on the compressor. By adopting the embodiment of the invention, the low-temperature heating capacity of the compressor can be improved, and better user experience is provided. 本发明公开了一种空调器及其控制方法，在压缩机系统中引入中间补气结构，在空调器处于低温制热模式时，启动电磁阀，以使冷媒从所述压缩机流出后，通过所述室内换热器后从所述闪发器的入口流进所述闪发器，一路液态
