Outdoor fan control system of air conditioner and control method thereof

A system to control at least one outdoor fan of an air conditioner, comprising:

• a compressor in which an amount of discharge of refrigerant is variable during its operation;
• an outdoor heat exchanger connected to said compressor;
• one or more outdoor fans positioned near said outdoor heat exchanger;
• an outdoor temperature sensor to sense an outdoor temperature;
• and
• a control unit to control said at least one outdoor fan to be operated in one of preset operation modes according to said sensed outdoor temperature and said amount of discharge of refrigerant of said compressor, wherein,
• as said outdoor temperature becomes higher and a loading time of said compressor becomes longer, said selected one of said preset operation modes allowing the rotational speed of said outdoor fan to become higher.
