Abstract

Eine erfindungsgemäßer Kältekreislauf, in dem ein ein- oder mehrkomponentiges Kältemittel, insbesondere CO2, zirkuliert, weist in Strömungsrichtung einen Verflüssiger/Gaskühler (1), eine Zwischen-Entspannungsvorrichtung (a), einen Sammelbehälter (3), eine einem Verdampfer (E2, E3) vorgeschaltete Entspannungsvorrichtung (b, c), einen Verdampfer (E2, E3) und eine Verdichtereinheit (6) auf. Eine weitere Verdichtereinheit (10) sowie wenigstens ein Tiefkühlverbraucher (E4) mit einem vorgeschalteten Entspannungsventil (d) sind vorgesehen. Im Betrieb wird ein Kältemittelteilstrom aus dem Sammelbehälter (3) dem wenigstens einen Tiefkühlverbraucher (E4) zugeführt und nach der darin erfolgten Verdampfung der weiteren Verdichtereinheit (10) zugeführt, die den Kältemittelteilstrom verdichtet und der Eingangsseite der Verdichtereinheit (6) zuführt.
