A heat pump system for a motor vehicle is disclosed. The heat pump system includes a refrigerant circuit that is flowable through by a refrigerant. The refrigerant circuit has a first partial circuit with a low pressure accumulator, a compressor, a heat pump heater, and an exterior heat exchanger. The refrigerant circuit has a second partial circuit with an evaporator and a chiller. The refrigerant circuit has a valve arrangement. The first partial circuit and the second partial circuit are fluidically connected with one another exclusively via the valve arrangement.

Heating pump system

An intermediate refrigerant store of a refrigerant system may include a storage container delimiting a refrigerant storage space, a first feed, and a second feed separate from the first feed. The first feed and the second feed may be fluidically connected with the refrigerant storage space for feeding of a refrigerant. At least one discharge may be fluidically connected to the refrigerant storage space and may be configured to discharge the refrigerant from the refrigerant storage space. At least one valve arrangement may be disposed in an associated feed of the first feed and the second feed via which the associated feed may be fluidically closable and openable.

Intermediate store for refrigerant and refrigerant system

A temperature control device of a vehicle may include an energy storage device, a first coolant circuit configured to temperature control the energy storage device, a refrigerant circuit, at least one refrigerant evaporator, a second coolant circuit, a refrigerant condenser, and a coolant cooler for transferring heat to an exterior environment. At least one section of the first coolant circuit and at least one section of the second coolant circuit may be defined by a shared circuit section. The coolant cooler may be fluidically connectable with at least one of the first coolant circuit and the second coolant circuit via the shared circuit section. The first coolant circuit may include a bypass for at least partially bypassing the coolant cooler. The first coolant circuit may include a valve device structured and arranged to distribute a first coolant flow to at least one of the shared circuit section and the bypass.

Device for the temperature of an energy storage device

An air conditioning system for a motor vehicle. The air conditioning system includes a refrigerant circuit divided into a high-pressure region and a low-pressure region, first and second internal heat exchangers arranged in the high-pressure and low-pressure regions, an external heat exchanger arranged in the refrigerant circuit, a condenser arranged in the high-pressure region, and an evaporator that, in a first operating mode, thermally couples the low-pressure region to the air conditioning air and, in a second operating mode, is arranged outside the refrigerant circuit.

Refrigerant system with two inner heat exchangers

A cooling system for a motor vehicle may include a first circuit, a second circuit, a first heat exchanger incorporated in the first circuit, and a second heat exchanger incorporated in the second circuit. The first heat exchanger and the second heat exchanger may be flowed through by ambient air and a coolant. The first heat exchanger may be arranged, relative to an airflow direction, in front of and directly adjacent to the second heat exchanger. The first circuit and the second circuit may be fluidically connected to one another at an upstream distribution point and at a downstream collection point such that a part mass flow of the coolant is flowable from the second circuit into the first circuit at the distribution point, from the first circuit into the first heat exchanger, and out of the first heat exchanger back into the second circuit at the collection point.

Cooling system and a cooling arrangement for a motor vehicle

A thermal management system for a vehicle may include a refrigerant circuit in which a refrigerant circulates, as well as a heating circuit, a first coolant circuit configured for a temperature control of a drive device of the vehicle, and a second coolant circuit configured for a temperature control of an electrical store of the vehicle in which a coolant circulates. The system may further include a chiller incorporated in the refrigerant circuit and a chiller guide fluidically separate from the refrigerant circuit. The chiller guide may have a chiller path configured to conduct the coolant and which extends through the chiller, and may have a bypass path configured to conduct the coolant and which circumvents the chiller. The system may additionally include a chiller valve device configured to selectively fluidically connect the first coolant circuit and the second coolant circuit to the chiller path and the bypass path.
