AIRCONDITIONER AND HEAT TEMPERATURE CONTROL METHOD OF POWER TRANSISTOR OF AIRCONDITIONER

摘要

The present invention relates to a method for controlling the heating temperature of an inverter-operated air conditioner and a power transistor of the inverter-operated air conditioner, the compressor having a drive motor, and an inverter for converting DC power into alternating current and providing the drive motor. An inverter operated air conditioner comprising: a temperature sensor for sensing an external temperature; When the external temperature sensed by the temperature sensor is more than a predetermined, characterized in that having a control unit for lowering the current input to the inverter by a predetermined value. As a result, the heating temperature of the power transistor can be controlled in a constant manner regardless of the temperature change of the outside air.
