Refrigerant circuit

A refrigerant circuit, in particular for a motor vehicle,

• wherein a refrigerant, in particular a refrigerant containing CO2, circulates through the refrigerant circuit when in operation, the refrigerant circuit comprises:
• exterior heat exchanger for exchanging heat in the refrigerant with the environment, in particular ambient air,
• a chiller heat exchanger for exchanging heat in the refrigerant with a temperature control fluid,
• an evaporator heat exchanger for exchanging heat in the refrigerant with air to be supplied to an interior,
• a gas cooler heat exchanger for exchanging heat in the refrigerant the air to be supplied to the interior,
• a compressor, which pressurizes the refrigerant when in operation,
• wherein the exterior heat exchanger, the chiller heat exchanger, the evaporator heat exchanger, and the gas cooler heat exchanger each have respective intakes through which refrigerant is received, and respective outlets through which the refrigerant is discharged,
• the refrigerant circuit further comprises a combination valve, which contains a first entry that has a fluid connection to a pressurized end of the compressor, such that pressurized refrigerant flows through the compressor to the first entry,
• wherein the combination valve contains a valve element assembly with at least one valve element and a housing in which the valve element assembly is housed such that it can be adjusted,
• wherein the combination valve is configured such that the valve element assembly can be set to various settings, allowing or blocking the flow of the refrigerant to at least three of the group consisting of the exterior heat exchanger, the chiller heat exchanger, the evaporator heat exchanger, and the gas cooler heat exchanger, such that the refrigerant is distributed in the refrigerant circuit by the combination valve.
