PURPOSE: A method for controlling operation of outdoor fan of inverter air conditioner is provided to prevent damage to power elements and circuit elements by controlling velocity of air produced from the outdoor fan in accordance with the cycle state of the air conditioner. CONSTITUTION: A method comprises a step(100) of judging whether the air conditioner is in heating operation; a step(103) of judging whether the bi-metal thermostat has changed its operation ; a step(106,109) of operating the outdoor fan in a strong wind mode for a predetermined time if it is judged in the step(103) that the bi-metal thermostat has changed its operation; a step(112) of detecting an outdoor temperature if the bi-metal thermostat has not changed; a step(115,118) of judging whether the detected outdoor temperature is higher than C1 deg.C, and operating the outdoor fan in a weak wind mode if the outdoor temperature is higher; a step(121,124) of judging whether the input power is lower than a1 volt, and operating the outdoor fan in a strong wind mode if yes; a step(133,136) of operating the outdoor fan in a weak wind mode if the outdoor temperature is lower than C1 deg.C and the input power is higher than a2 vo a step(139,142) of judging whether the outdoor temperature is higher than C2 deg.C, and operating the outdoor fan in a strong wind mode if yes; a step(145,148) of judging whether the operation frequency of the compressor is higher than a rated frequency and operating the outdoor fan in a strong wind mode if yes; and a step(151) of operating the outdoor fan in a weak wind mode if no.
