PROBLEM TO BE SOLVED: To provide a vehicular air-conditioning system capable of enlarging the effective range of a dehumidification heating mode against an environmental condition to thereby smoothly dehumidify and warm the inside of a cabin.SOLUTION: In a vehicular air-conditioning system 1 for executing a dehumidification heating mode, in which a coolant discharged from a compressor 2 is subjected to heat radiation by a radiator 4 and the heat-radiated coolant is reduced in pressure and then caused to absorb the heat in a heat absorber 9 and an outdoor heat exchanger 7, the controller lowers an outdoor blower voltage FANVout of an outdoor blower 15 to thereby reduce the air flow to the outdoor blower 15, in the case where a temperature TCI of the radiator 4 is satisfactory and a temperature Te of the heat absorber 9 is high even if the valve opening of an outdoor expansion valve 6 is set to a control lower limit value. |
