The invention relates to a rail vehicle having at least one energy accumulator, in which electrical energy for supplying a traction device can be stored, a cooling device, which is arranged in a coolant circuit and cools the energy accumulator, wherein a liquid coolant can circulate in the coolant circuit, and a refrigeration device having a first refrigerant circuit in which a refrigerant can circulate. The rail vehicle also has a first heat exchanger, which is arranged in the coolant circuit and in the first refrigerant circuit and in which the coolant can be cooled by means of the refrigerant, an air-conditioning device having a second heat exchanger, wherein a space usable by at least one person can be air-conditioned by means of a forced air-conditioning air flow guided through the second heat exchanger, as well as a control device. According to the invention, the second heat exchanger is arranged solely in the coolant circuit and is connected downstream of the first heat exchanger in the flow direction of the coolant.
