The invention relates to an air-conditioning system for a rail vehicle, comprising a coolant circuit which can be switched between a cooling operation and a heating operation and which has - a first heat exchanger (3) that interacts with surrounding air (A) and operates as a condenser during the cooling operation and as an evaporator during the heating operation, - a second heat exchanger (12) which conditions supply air (Z) for a passenger compartment, - an expansion valve (11), - a compressor (10), and - a valve assembly for switching between the cooling operation and the heating operation. The invention is characterized in that the coolant circuit has - a primary coolant circuit (1), which comprises the first heat exchanger (3), the expansion valve (11), the compressor (10), the valve assembly for switching between the cooling operation and the heating operation, and a primary side of a third heat exchanger (16) that operates as an evaporator during the cooling operation and as a condenser during the heating operation, and - a secondary coolant circuit (2), which comprises the secondary side of the third heat exchanger (16) and the second heat exchanger (12). A switchable electric heating device for heating a coolant supply flow for the second heat exchanger (12) is arranged between the coolant fluid outlet on the secondary side of the third heat exchanger (16) and a coolant fluid inlet of the second heat exchanger (12).
