OPERATION CONTROL METHOD OF AIR CONDITIONER ON POWER FAILURE

摘要

PURPOSE: An operation control method of an air conditioner is provided to automatically return the operating state of an air conditioner to the state before the power cut when the air conditioner is returned from the stopped state by the power failure. CONSTITUTION: The operation control method of an air conditioner in the power failure contains the steps of:judging if the electric current is off through the voltage signal fed through a PI terminal(210) while the air conditioner is normally operating; a control unit(130) memorizing the current operating mode and judging if the power failure is dissolved, if the current is off; and a control unit(130) normally operating the air conditioner to the previous mode of the power failure by leading the memorized mode if the power failure is dissolved.
