  • Apparatus for preventing overload of air conditioner and method thereof
    Publication number: 20030217557
    Abstract: Disclosed are an apparatus for preventing an overload of an air conditioner and a method thereof. The apparatus includes current feedback units for feeding back the currents supplied to the compressors to the controller where at least one of a plurality of compressors, operated in response to currents generated from a controller for controlling an operation of the air conditioner, is in an overload state; and a comparator for sensing current differences between the currents inputted into the compressors and the currents fed back from the current feedback units. After sensing the current differences between the currents inputted into the compressors and the currents fed back from the current feedback units, the comparator determines that at least one of the compressors is in the overload state if a current difference does not exist.
