Title
(EN) METHOD OF CHARGING MIXED COOLING MEDIUM
(FR) PROCEDE DE CHARGEMENT D'UN AGENT DE REFROIDISSEMENT MIXTE
Abstract
(EN) To use a non-azeotropic mixture consisting of HFC32 (23 wt.%), HFC125 (25 wt.%) and HFC134a (52 wt.%) as a cooling medium, the mixture in a container on the supply side such as a bomb is made to have a composition of HFC31 (23.5 to 25.0 wt.%), HFC125 (23.5 to 25.0 wt.%) and HFC134a (50.0 to 53.0 wt.%), and extracted from thte liquid phase at a temperature not higher than 40 °C. The change of the composition due to the charging is within an allowable range of cooling performance.
(FR) Pour utiliser un mélange non azéotrope composé de HFC32 (23 % en poids), de HFC125 (25 % en poids) et de HFC134a (52 % en poids) comme agent de refroidissement, on maintient la composition du mélange dans un conteneur destiné à l'alimentation, telle une bombe, par exemple, dans les limites suivantes: de 23,5 à 25,0 % en poids de HFC32, de 23,5 à 25,0 % en poids de HFC125 et de 50,0 à 53,0 % en poids de HFC134a et on extrait ledit mélange de la phase liquide à une température de 40 °C maximum. Le changement de composition dû au chargement du mélange non azéotrope se maintient dans une plage acceptable de rendement de refroidissement.
