The invention relates to an air-conditioning device for a motor vehicle and to a method for the operation thereof, comprising a refrigerant circuit (100) with a compressor (102) for compressing refrigerant, with a first interior heat exchanger (111), which is positioned downstream of the compressor (102) in a refrigerant flow direction and which is designed as an air-refrigerant heat exchanger and which can be operated as a condenser, and with a second interior heat exchanger (112), which is positioned downstream of the first interior heat exchanger (111) in the refrigerant flow direction via an expansion valve (141, 142) and which is designed as an air-refrigerant heat exchanger and which can be operated as an evaporator, and comprising a coolant circuit (200) with a coolant pump (211, 221) and with a chiller (222) which is thermally coupled to electric drive components of the motor vehicle, wherein the coolant circuit (200) and the refrigerant circuit (100) are thermally coupled to one another by means of a coupling heat exchanger (130) which is designed as a coolant/refrigerant heat exchanger, and the circuit arrangement composed of the coolant circuit (200) and the refrigerant circuit (100) has an exterior heat exchanger (213) which is thermally coupled to the air surrounding the motor vehicle. The invention is distinguished by the fact that the exterior heat exchanger (213) is designed as an air/coolant heat exchanger which is integrated into the coolant circuit (200).
