  • Ejector cycle
    Patent number: 9217590
    Abstract: A system (200; 300; 400; 500; 600) has a compressor (22; 200, 221). A heat rejection heat exchanger (30) is coupled to the compressor to receive refrigerant compressed by the compressor. An ejector (38) has a primary inlet (40) coupled to the heat rejection heat exchanger to receive refrigerant, a secondary inlet (42), and an outlet (44). A separator (48) has an inlet (50) coupled to the outlet of the ejector to receive refrigerant from the ejector, a gas outlet (54), and a liquid outlet (52). One or more valves (244, 246, 248, 250) are positioned to allow switching of the system between first and second modes.

  • REFRIGERATION CIRCUIT
    Publication number: 20110146313
    Abstract: A refrigeration circuit has a mono- or multi-component refrigerant, especially CO2, circulating therein, said refrigeration circuit enabling an transcritical operation, said refrigeration circuit comprising, in the direction of refrigerant flow, a compressor unit, a condenser/gascooler, a high pressure control valve, a collecting container, and at least one evaporator having an expansion device connected upstream thereof, wherein a flashgas line having a medium pressure control valve arranged therein is provided between an upper portion of the collecting container and the suction line leading to the compressor unit, wherein a temperature, pressure or liquid level sensor is provided in or at the collecting container, wherein a bypass line having a medium pressure holding valve arranged therein is provided connecting the line between the condenser/gascooler and the high pressure control valve to the line between the collecting container and the expansion device(s), and wherein a control unit is provided said co
