Abstract: A system for air-conditioning air of a passenger compartment and for heat transfer with drive components of a motor vehicle. The system has a refrigerant circuit and a coolant circuit. The refrigerant circuit is formed with a compressor, a first refrigerant-coolant heat exchanger operated as a condenser/gas cooler, a refrigerant-air heat exchanger operated as an evaporator for conditioning supply air of the passenger compartment with an 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 the refrigerant with an upstream expansion element, and with a bypass flow path around the heat exchangers operated as the evaporators on the low-pressure side. In addition to the first refrigerant-coolant heat exchanger, the coolant circuit has a coolant-air heat exchanger operated as a thermal heat exchanger for heating supply air of the passenger compartment.

Abstract: An air conditioning and battery cooling assembly with an A/C coolant circuit and an E-drivetrain coolant circuit as well as a refrigerant circuit, wherein the A/C coolant circuit and the E-drivetrain coolant circuit are coupled together across a 4/2-way coolant valve in such a way that the A/C coolant circuit and the E-drivetrain coolant circuit can be operated separately or can receive a flow in serial manner.
