Specifically, after the air conditioner receives the indication information, the air conditioner enters a quick refrigeration mode according to the indication information, at this time, the air conditioner needs to acquire outdoor environment temperature, so as to determine initial working frequency of the compressor and initial rotating speed of the outdoor fan according to the condition of the outdoor environment temperature, start the compressor according to the initial working frequency, and start the outdoor fan according to the initial rotating speed, so that the air conditioner can start with high refrigerating capacity as much as possible under the condition of meeting the requirement of the outdoor environment temperature, and the air conditioner enters the quick refrigeration mode.
In an embodiment, an initial operating frequency of the compressor and an initial rotational speed of the outdoor fan are determined from a preset first correspondence table according to an outdoor environment temperature, where the first correspondence table is a correspondence table of the outdoor environment temperature, the initial operating frequency and the initial rotational speed, and the initial operating frequency and the initial rotational speed are both in positive correlation with the outdoor environment temperature, so that the air conditioner can be started with a high refrigerating capacity as much as possible under the condition of meeting the outdoor environment temperature requirement, so that the air conditioner enters a fast refrigerating mode.
In an embodiment, when the air conditioner receives the indication information, which indicates that the user needs the air conditioner to enter the fast cooling mode, the air conditioner detects the outdoor environment temperature T4, and determines the initial operating frequency of the compressor and the initial rotation speed of the outdoor fan from a preset first correspondence table according to the outdoor environment temperature.
In the first correspondence table, the outdoor ambient temperature is divided into 3 sections, T4< a, a < T4< b, and b < T4< c, where a is set to a range of 32-35 ℃, b is set to a range of 35-43 ℃, and c is set to a range of 43-48 ℃.
When T4< a, the initial rotating speed of the corresponding outdoor fan is S1 (the range of S1 is 800-1000 r/S), and the initial frequency of the compressor is F1 (the range of F1 is 20hz-24 hz);

In an embodiment, the limit temperature of the outdoor heat exchanger is determined according to the outdoor environment temperature from a preset second correspondence table, where the second correspondence table is a correspondence table between the outdoor environment temperature and the limit temperature of the outdoor heat exchanger, and the partition of the outdoor environment temperature T4 in the second correspondence table may be the same as the partition of the outdoor environment temperature T4 in the first correspondence table in the above embodiment, for example, the outdoor environment temperature T4 is divided into 3 sections, T4< a, a < T4< b, and b < T4< c, where a is set to 32-35 ℃, b is set to 35-43 ℃, and c is set to 43-48 ℃. When T4< a, the corresponding limit temperature is T5; when a < T4< b, the corresponding limit temperature is T6; when b < T4< c, the corresponding limit temperature is T7.
