Abstract: The present invention provides a vehicle air-conditioning system comprising: a pair of evaporation units which cause heat exchange between a refrigerant and air, and which are arranged to be spaced apart from each other so as to discharge cold air in different directions; one expansion valve, which expands a low-temperature and high-pressure refrigerant so as to supply same to the evaporation unit; an inlet pipe in which the refrigerant of the expansion valve moves to a first evaporation unit; a first moving pipe in which the refrigerant having circulated through one region of the first evaporation unit moves to a second evaporation unit; a second moving pipe in which the refrigerant having circulated through the second evaporation unit moves to the first evaporation unit; and an outlet pipe through which the refrigerant having circulated through the first evaporation unit flows out.
