The present invention relates to a vehicle air conditioner system and, more specifically, to a vehicle air conditioner system formed by including a compressor, an integrated condenser in which a water-cooled region and an air-cooled region are integrally formed, an expansion valve, and an evaporator, wherein the water-cooled region and the air-cooled region of the integrated condenser are formed on one plate such that a conventional air-cooled condenser and water-cooled condenser can be integrally formed through a single brazing operation, thereby reducing a package and simplifying assembly and manufacturing processes.
