Abstract:
(DE) Die Erfindung betrifft eine Kälteanlage, insbesondere eine Kraftfahrzeug-Klimaanlage (4), mit einem von CO2 als Kältemittel durchströmten Kältemittelkreislauf (2), der einen Verdichter (6), einen Kondensator bzw. Gaskühler (10), ein Expansionsorgan (18) mit einem regelbaren Drosselquerschnitt und einen Verdampfer (20) umfasst. Es ist vorgesehen, dass ein Regelbereich des Drosselquerschnitts maximal etwa 1 mm2 beträgt.
(EN) The invention relates to a cooling system, in particular, a motor vehicle air conditioning system (4), comprising a coolant circuit (2) which can be cross-flown by CO2 which acts as a coolant, said coolant circuit comprising a compressor (6), a capacitor and/or a gas cooler (10), an expansion element (18) comprising a controllable throttle cross-section and a vaporiser (20). According to the invention, the maximum control area of the throttle cross-section is approximately 1 mm2.
(FR) L'invention concerne une installation de refroidissement, en particulier une installation de climatisation de véhicule automobile (4), comprenant un circuit de réfrigérant (2) qui est traversé par un réfrigérant se présentant sous la forme de CO2, et qui comprend un compresseur (6), un condenseur ou appareil de refroidissement à gaz (10), un organe d'expansion (18) comportant une section transversale d'étranglement, et un évaporateur (20). Cette invention est caractérisée en ce que la zone de régulation maximale de la section transversale d'étranglement est approximativement égale à 1 mm2.
