Supercritical
refrigerant circuit with compressor-ejector combination for vehicle
air conditioning, comprising a section for a total
refrigerant flow, a section for a suction jet
refrigerant partial flow, and a section for a motive jet refrigerant partial flow, wherein in the section for the suction jet refrigerant partial flow an
air conditioning evaporator (8) with associated expansion element (9) for providing cooling in an
air conditioning system (32), a compressor (1), a
gas cooler (2), an expansion element (5), and a suction jet
heat exchanger (6), and in the section for the motive jet refrigerant partial flow a motive jet
heat exchanger (33), wherein an ejector (7) is provided in which the suction jet refrigerant partial flow and the motive jet refrigerant partial flow of the refrigerant circuit are combined.wherein an ambient
heat exchanger (10) and, in parallel, an air conditioning
gas cooler (12) for providing heat in the air conditioning
system (32) and, subsequently, a subcooler (11) are arranged in the total refrigerant flow, after which the total refrigerant flow is divided into the suction jet refrigerant partial flow and the motive jet refrigerant partial flow.
