A rail car air-conditioning device is equipped with: a refrigerant circuit that has a compressor and an outdoor heat exchanger; an outdoor blower; a compressor operation frequency deriver that derives a compressor operation frequency of the compressor on the basis of a rail car interior setting temperature and a rail car interior temperature; an inverter for compressor use that drives the compressor at the compressor operation frequency; an outdoor blower operation frequency deriver that, in accordance with a predetermined correspondence relationship, derives a blower operation frequency of the outdoor blower corresponding to the compressor operation frequency; and an inverter for outdoor blower use that drives the outdoor blower at the blower operation frequency. The outdoor blower operation frequency deriver has a highly energy efficient energy-saving mode and a low-energy efficiency low-noise mode, and can switch between the energy-saving mode and the low-noise mode.
