1. A system for air-conditioning air of a passenger compartment and for heat transfer with drive components of a motor vehicle, comprising:
a refrigerant circuit with a compressor, a first refrigerant-coolant heat exchanger operated as a condenser/gas cooler, a first refrigerant-air heat exchanger operated as an evaporator for conditioning supply air of the passenger compartment with a first upstream expansion element, and a second refrigerant-coolant heat exchanger operated as an evaporator for heat transfer between a coolant for tempering the drive components of the motor vehicle and a refrigerant with a second upstream expansion element; and
a first coolant circuit with the first refrigerant-coolant heat exchanger and a first coolant-air heat exchanger operated as a thermal heat exchanger for heating the supply air of the passenger compartment, wherein the refrigerant circuit is formed on a low-pressure side with a first bypass flow path around the first refrigerant-air heat exchanger operated as the evaporator and the second refrigerant-coolant heat exchanger operated as the evaporator, wherein the refrigerant circuit is formed with a second refrigerant-air heat exchanger for heat transfer between the refrigerant and ambient air, which, in a direction of flow of the refrigerant, is arranged after the first refrigerant-coolant heat exchanger, and wherein the second refrigerant-air heat exchanger is arranged for heat transfer between the refrigerant and the ambient air within an air duct for targeted passing of the ambient air, which is closable by means of a flow guide.
