Abstract

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.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner low-temperature refrigeration control method and the air conditioner. Background technique [0002] In the traditional control method of the air conditioner, when the outdoor temperature is higher than the predetermined temperature, it can exert a good cooling capacity, but when the outdoor temperature is lower than the predetermined temperature, if the air conditioner continues to cool according to the traditional method, liquid refrigerant will flow into the compressor This can damage the compressor and freeze the indoor heat exchanger. [0003] In order to achieve the effect of cooling in low temperature environment, in the existing air conditioners, the method of reducing the speed of the outdoor fan is usually used to reduce the outdoor heat exchange, so that the air conditioner will not cause indoor heat exchange due to too much cooling capacity....
