Title (EN) REFRIGERANT ANALYZER AND A METHOD OF USING THE SAME
(FR) ANALYSEUR DE FLUIDE FRIGORIGÈNE ET SON PROCÉDÉ D'UTILISATION
Abstract:
(EN) A method and an analyzer for detecting impurities in refrigerant (e.g. methyl chloride (R40) or Chlorodifluoromethane (R22)), wherein the refrigerant analyzer (12) includes a first sensing device (16), preferably a non-dispersive infrared sensor (NDIR), in flow communication with a second sensing device (18), preferably an electrochemical sensor. The first sensing device is configured to determine a first characteristic of a refrigerant (e.g. absorbance in the IR range), and the second sensing device is configured to detect a second characteristic of the refrigerant (e.g. concentration in ppmv). Preferably, the refrigerant analyzer is a part of a system for detecting impurities (10) and further preferably it comprises flow regulators (20), a scrubber (24) and a processor (22). The scrubber is preferably in flow communication with the first sensing device and it preferably comprises a packing material comprising alumina (AI203, aluminum oxide).
(FR) L'invention concerne un procédé et un analyseur pour détecter des impuretés dans un fluide frigorigène (par exemple, le chlorure de méthyle (R40) ou le chlorodifluorométhane (R22)), l'analyseur de fluide frigorigène (12) comprenant un premier dispositif de détection (16), de préférence un capteur infrarouge non dispersif (NDIR), en communication fluidique avec un second dispositif de détection (18), de préférence un capteur électrochimique. Le premier dispositif de détection est configuré de façon à déterminer une première caractéristique d'un fluide frigorigène (par exemple l'absorbance dans la plage des infrarouges (IR)), et le second dispositif de détection est configuré pour détecter une seconde caractéristique du fluide frigorigène (par exemple la concentration en ppmv). De préférence, l'analyseur de fluide frigorigène fait partie d'un système de détection d'impuretés (10) et en outre il comprend de préférence des régulateurs de débit (20), un épurateur (24) et un processeur (22). L'épurateur est, de préférence, en communication fluidique avec le premier dispositif de détection et il comprend, de préférence, un matériau de remplissage comprenant de l'alumine (Al2O3, oxyde d'aluminium).
