Abstract: The present invention relates to a vehicle air-conditioning system and, more particularly, to a vehicle air-conditioning system in which an air-conditioning module consisting of an air-conditioning case and a blowing apparatus is disposed at a side of an engine room with respect to a dash panel, and a distribution duct for distributing cold and hot air discharged from the air-conditioning case into the inside of a vehicle is disposed on the indoor side of the vehicle with respect to the dash panel.
