To propose a vehicle air-conditioning system capable of further reducing a temperature fluctuation of blowing-out air when temperature-conditioned air is supplied to an in-car space. The vehicle air-conditioning system including a cooling apparatus 5 capable of changing an amount of withdrawn heat in a stepwise manner, heaters 6A, 6B, and 6C, each having different heat release capability, which constitutes a heating apparatus 6 capable of changing an amount of generated heat in a stepwise manner, and a control device 30 including a supplying amount of heat calculating portion 30A for calculating a supplying amount of heat to an in-car space 2 and an amount of generated and withdrawn heat setting portion 30B for setting amounts of withdrawn and generated heat of the cooling apparatus 5 and the heating apparatus 6 on the basis of the supplying amount of heat calculated by means of the supplying amount of heat calculating portion 30A.
