Abstract: PURPOSE: An initial operation control method for an air conditioner is provided to reduce vibration and noise and to prevent waste of electricity by reducing load increase through control of voltage supplied to a compressor at an initial stage of operation. CONSTITUTION: A voltage control unit(7) falls normal power supplied to an outdoor control unit(8) and a compressor driving unit(6) to a minimum driving voltage for composition of a refrigerant cycle and applies the decreased power to a compressor(1). The minimum driving voltage is -10% of the normal power. For single-phase 60Hz 220V normal power, power is fallen down to 220V. Then, rpm of the compressor decreases and the compressor is operated slowly. Thus, initial load or flow change of a refrigerant cycle is minimized. After an air conditioner system is operated continuously and flow change of the refrigerant cycle is reduced, the voltage control unit increases voltage gradually and periodically to 200V. Therefore, load is reduced at an initial stage of air conditioner operation and smooth operation is realized.
