METHOD OF CONTROLLING ACTION OF AIR CONDITIONER IN LOW VOLTAGE

摘要

PURPOSE: A method is provided to prevent temperature of a coil from rising in low voltage by boosting the low voltage to normal voltage through a booster. CONSTITUTION: An air conditioner is controlled by the steps of: deciding if a ran switch is switched on through an on-signal fed from the ran switch; comparing the input voltage detected from a voltage measurer with electrostatic pressure; normally driving an air conditioner if the input voltage is the same or higher than the electrostatic pressure; switching a switch of a converter to a booster so the input voltage as to flow into the booster if the input voltage is lower than the electrostatic pressure; and normally driving the air conditioner by feeding the boosted voltage through the booster.
