| 摘要 |
The present invention relates to an air conditioning device for an electric vehicle. The purpose of the invention is to increase heating efficiency in a vehicle while reducing a heating amount of a PTC heater by efficiently controlling an opening angle of a temperature control door for cold and hot wind paths in a heating mode, thereby improving fuel efficiency. For the purpose, the invention, as an air conditioning device including a PTC heater heating air flowing through a hot wind path and a temperature control door controlling the opening of the cold and hot wind paths while rotating between the paths, includes a control part controlling the opening angle of the temperature control door for the hot wind path and the heating amount of the PTC heater according to a set target discharge temperature when the temperature is set in the heating mode. The control part controls the opening angle based on opening angle data corresponding to a higher temperature than the target discharge temperature.
