When the rotating speed of two level wind turbine 3 is adjusted to maximum, still T2＞ C make two level wind turbine 3 keep maximum (top) speed operation.
Thus, it is possible to the air quantity of outdoor heat exchanger is blowed to by opening level-one wind turbine 2 and the increase of two level wind turbine 3, so as to
To effectively improve the heat exchange efficiency of outdoor heat exchanger.
According to the control method of the air conditioner of the utility model embodiment, air conditioner can be effectively improved in cryogenic refrigeration
Refrigeration effect under pattern and room temperature refrigeration mode, and control method is simple, it is at low cost.
