The invention provides a low-temperature refrigerating control method of an air conditioner and the air conditioner. By the adoption of the low-temperature refrigerating control method of the air conditioner and the air conditioner, the technical problem that an air conditioner cannot conduct refrigeration continuously under a low-temperature condition is solved. The control method comprises the following steps that when the air conditioner conducts refrigeration, the outdoor environment temperature is detected; whether the detected outdoor environment temperature is lower than a set temperature threshold value or not is judged; and if so, the operation frequency of a compressor of the air conditioner is lowered to be within a preset frequency range, and the superheat degree of the air conditioner is increased by preset degrees. According to the air conditioner adopting the control method, the effect that an indoor heat exchanger cannot enter a freeze protection mode at the low temperature is guaranteed, the indoor heat exchange capacity is improved, and then the refrigerating capacity is improved; in addition, continuous operation of the compressor is achieved, and the technical effect of continuous refrigeration is achieved at the low temperature.
