PURPOSE: A vehicle air conditioning system is provided to reduce noise by allowing the air blown from the blower fan to smoothly flow through the connection part between the blower case and evaporator case. CONSTITUTION: A vehicle air conditioning system includes a blower(6), an evaporator(9), an air mix damper(11), a heater and a switch damper(8) which are arranged at the air flow channel formed between an air inlet port(7) and an air outlet port of an intake case(2). A blower case(3) has a cylindrical section(3a) for installation of the blower, a straight line section(3b) to be coupled with a cooler case(4) so as to guide the air introduced by the blower toward the downstream, and a curved section(3c) curved outward with respect to the portion where the cylindrical section and the straight line section meet. The curved section has an auxiliary wheel(13) mounted within the curved section, in such a manner that both ends of the rotation shaft are coupled to an upper case and a lower case of the blower case, respectively.
