  • Air-conditioning unit with additional heat transfer unit in the refrigerant circuit
    Patent number: 6910345
    Abstract: The invention relates to an air-conditioning unit (10) for a motor vehicle with a heating heat transfer unit (28) connected to a coolant circuit (42) in an internal combustion engine and comprising an evaporator (22) installed upstream in the direction of flow of a fan (36). A compressor (12) in a refrigerant circuit (32) pumps a refrigerant through a gas cooler (16) and an expansion valve (20) during a cooling operation, and pumps said refrigerant to the evaporator (22) via the expansion valve (20) by by-passing the gas cooler (16) during a heating operation. A coupled heat exchanger (30) is provided between the coolant circuit (42) and the refrigerant circuit (32).
