The commissioning of an air conditioning system requires a series of manual steps, which leads to inefficient commissioning. A method is therefore provided for commissioning an air conditioning system of a vehicle, including the following: a) Reading in a target data record indicating a target vehicle state; b) Recording an actual data record indicating an actual vehicle state by measuring at least one signal and/or communicating with at least one vehicle component; c) Comparing the actual vehicle state with a target vehicle state; d) Activating at least one function of the air conditioning system only if the actual vehicle state corresponds to the target vehicle state.

The invention relates to a method for operating a climate-control system (12) for a vehicle (10). According to the invention, total energy efficiencies are determined for a group of operating strategies for the air-conditioning system (12) and an operating strategy with the greatest total efficiency that fulfills the heating output requirement (44) that has been determined, is selected.

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.

A heating temperature is appropriately estimated according to an operation mode to achieve comfortable vehicle interior air conditioning. A vehicular air conditioning device 1 includes a compressor 2, an air flow passage 3, a radiator 4 for heating air to be supplied to a vehicle interior, a heat absorber 9 for cooling the air to be supplied to the vehicle interior, and a heat pump controller. The heat pump controller calculates a heating temperature TH being the temperature of air on a leeward side of the radiator and use the heating temperature in control, and calculates the heating temperature TH using an estimation formula which differs depending on the operation mode.

A vehicle-mounted temperature controller includes a low temperature circuit and a refrigeration circuit. The low temperature circuit has a heat generating equipment heat exchanger exchanging heat with heat generating equipment, a radiator, a first heat exchanger, and a three-way valve. The refrigeration circuit has a second heat exchanger discharging heat from the refrigerant to a high temperature circuit to make the refrigerant condense, and the first heat exchanger making the refrigerant absorb heat from the cooling water to make the refrigerant evaporate. The low temperature circuit includes a first partial circuit through which the cooling water flows through the radiator and the first heat exchanger, and a second partial circuit through which the cooling water flows through the heat generating equipment heat exchanger without passing through the radiator and the first heat exchanger. The cooling water circulates simultaneously and separately at these first partial circuit and second partial circuit.

Heat flow management device for motor vehicles has a refrigerant circulation, a power train coolant circulation and a heating line heat carrier circulation. The refrigerant circulation includes a compressor, an indirect condenser, an expansion element, an ambient heat exchanger, an evaporator and a chiller. The power train coolant circulation includes a coolant pump, the chiller, an electric motor heat exchanger and a power train coolant radiator, wherein the heating line heat carrier circulation comprises a coolant pump, the indirect condenser and a heating heat exchanger, wherein the refrigerant circulation and the power train coolant circulation are directly thermally coupled with one another across the chiller. Refrigerant circulation and heating line heat carrier circulation are directly thermally coupled with one another across the indirect condenser. Power train coolant circulation and the heating line heat carrier circulation are only indirectly thermally coupled with one another across the refrigerant circulation.

A thermal management system for an electric vehicle includes an interior air conditioning part including an air inflow part, an air discharge part, a cooling core, a heating core arranged between the cooling core and the air discharge part, and an adjustment door. The adjustment door is selectively adjustable to control whether air from the cooling core may flow into the heating core. A heat transfer line connects an electric part core to the heating core for transferring that heat of the electric part to the heating core, in order to allow heat dissipation of the electric part through the heating core.

Methods and systems are provided for operating a climate control system. In one example, a method for operating a vehicle climate control system includes modeling a temperature in a cabin heating circuit coupled to a heat pump. The method also includes operating the heat pump to deliver thermal energy to a cabin heat exchanger based on the modeled temperature.
