In a vehicle air conditioner device of a heat pump system, control of an air mix damper is appropriately performed in each operation mode, thereby achieving efficient vehicle interior air conditioning. The vehicle air conditioner device includes an air mix damper 28 to adjust a ratio at which air in an air flow passage 3 passed through a heat absorber 9 is to be passed through a radiator 4. In a cooling mode, a controller controls the air mix damper 28 to adjust the ratio at which the air is to be passed through the radiator 4 on the basis of one, any combination, or all of a target outlet temperature, a temperature of the radiator and a temperature of the heat absorber, and in a heating mode, the controller controls the air mix damper 28 to pass all the air in the air flow passage 3 through the radiator 4.

A method for climate control, in which an overall mass flow of air is guided through an auxiliary heater, which has multiple zones. The overall mass flow is divided after flowing through the auxiliary heater into multiple partial mass flows, and an nth partial mass flow respectively flows out of an nth zone. A value of at least one flow parameter of an nth partial mass flow is ascertained, and at least one manipulated variable of a respective nth zone is set in dependence on the value of the at least one flow parameter. Overheating of at least one zone of the auxiliary heater is avoided.

An air-conditioning system of a motor vehicle may include a fan, an evaporator, and at least one heat exchanger. The evaporator may be arranged downstream of the heat exchanger and may both be arranged in a housing.
