Title
(EN) REFRIGERATION SYSTEM LEAK DETECTION
(FR) DÉTECTION DE FUITE DE SYSTÈME DE RÉFRIGÉRATION
Abstract
(EN) A refrigeration system includes: a leak sensor disposed within a building and configured to measure an amount of refrigerant that has leaked from the refrigeration system within the building; a prediction module configured to determine a predicted amount of refrigerant that has leaked from the refrigeration system within the building based on the measured amount; and a leak module configured to: determine whether a leak is present in the refrigeration system within the building based on the predicted amount of refrigerant that has leaked from the refrigeration system; and take one or more remedial actions when a leak is present in the refrigeration system within the building.
(FR) La présente invention concerne un système de réfrigération comprenant : un capteur de fuite disposé à l'intérieur d'un bâtiment et conçu pour mesurer une quantité de réfrigérant qui a fui du système de réfrigération à l'intérieur du bâtiment ; un module de prédiction conçu pour déterminer une quantité prédite de réfrigérant qui a fui du système de réfrigération à l'intérieur du bâtiment sur la base de la quantité mesurée ; et un module de fuite conçu pour : déterminer si une fuite est présente dans le système de réfrigération à l'intérieur du bâtiment sur la base de la quantité prédite de réfrigérant qui a fui du système de réfrigération ; et prendre une ou plusieurs actions correctives lorsqu'une fuite est présente dans le système de réfrigération à l'intérieur du bâtiment.
