But at the same time, the condensing temperature and condensing pressure are relatively small, which causes the refrigerant entering the indoor evaporator to be at a low evaporating pressure and evaporating temperature after the adiabatic throttling process. If the evaporating temperature is too low, the indoor

Abstract

The invention provides a low-temperature refrigeration control method, a low-temperature refrigeration control device and an air conditioner. The low-temperature refrigeration control method comprises the steps that in a low-temperature refrigeration mode, the outlet temperature of an outdoor condenser of the air conditioner is detected through a temperature sensor; the detected outlet temperature of the outdoor condenser is judged to be smaller than or equal to a preset outlet temperature or not; and according to the judging result, the covering area of a wind baffling device which is arranged outside the outdoor condenser of the air conditioner is adjusted. By adopting the technical scheme disclosed by the invention, the heat exchange between the outdoor condenser and the external environment is weakened; the pressure of an outdoor refrigerant is maintained at a reasonable range, and the problems of frosting, liquid slugging and the like caused by over-low pressure of the outdoor refrigerant are avoided; the operation safety of the air conditioning system at a low-temperature outdoor environment temperature is increased; and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a low-temperature refrigeration control method, a low-temperature refrigeration control device and an air conditioner. Background technique [0002] With the development of my country's economy and science and technology, people's material life has been greatly improved, especially the requirements for environmental comfort and cleanliness have gradually increased. Under the condition of low external ambient temperature, air conditioners still need to be operated for cooling in many occasions. Mode to keep the temperature and humidity of the room within a reasonable range, such as high-end restaurants, data centers, etc. [0003] When the traditional air conditioner is running in cooling mode, the external ambient temperature is often controlled at 25°C to 35°C. When the ambient temperature is lower than -10°C, if the air conditioner needs to run in cooling mode, ...
