System for air conditioning the air in a passenger compartment and for heat transfer with drive components of a motor vehicle, as well as a method for operating the system

摘要

The invention relates to a system (1a, 1b) for air conditioning the air in a passenger compartment and for heat transfer with drive components of a motor vehicle. The system (1a, 1b) has a refrigerant circuit (2a, 2b) with a compressor (5), a first refrigerant-coolant heat exchanger (6) operated as a condenser / gas cooler and at least one refrigerant-air heat exchanger (7) operated as an evaporator , 8) for conditioning the supply air of the passenger compartment with an upstream expansion element (10, 11), a first coolant circuit (3) with the refrigerant-coolant heat exchanger (6) and a coolant-air heat exchanger (26) operated as a heating heat exchanger and a second coolant circuit (4) with a coolant heat exchanger (31) for controlling the temperature of a drive component. The first coolant circuit (3) and the second coolant circuit (4) are materially separated from one another. The coolant circuits (3, 4) have a coolant-coolant heat exchanger (27) for heat transfer between the coolants circulating in the coolant circuits (3, 4). The invention also relates to a method for operating the system (1a, 1b).
