  "textContent": "To provide a highly-efficient vehicle air-conditioning system capable of ensuring the required cooling and heating capacities, and an automatic operation control method therefor. The vehicle air-conditioning system includes: an HVAC unit (2) that blows air whose temperature has been adjusted by a refrigerant evaporator (6) and a second refrigerant condenser (7); a heat pump cycle (3) in which a refrigerant compressor (8), a refrigerant circuit changeover section (11), a first refrigerant condenser (12), a first expansion valve (14), and the refrigerant evaporator (6) are sequentially connected, in which a second expansion valve (19) and a refrigerant/coolant heat exchanger (20) are connected in parallel with the first expansion valve (14) and the refrigerant evaporator (6), and in which the second refrigerant condenser (7) is connected in parallel with the first refrigerant condenser (12); and a coolant cycle (4) in which a coolant circulating pump (21), a ventilation-exhaust-heat recovery unit (22), a motor/battery (23), an electric heater (24), and the refrigerant/coolant heat exchanger (20) are sequentially connected, and in which the ventilation-exhaust-heat recovery unit (22), the motor/battery (23), and the electric heater (24) can be selectively used as a heat source.",
