Abstract
(EN)
The present application provides a refrigerant leakage detection method and system for an air conditioner, and the air conditioner. The air conditioner comprises a detection module and an energy storage module. The refrigerant leakage detection method for an air conditioner comprises the following steps: detecting the power state of the air conditioner; and if the air conditioner is in a power-off state, controlling the energy storage module to supply power to the detection module, so that the detection module can continuously detect whether a refrigerant of the air conditioner leaks or not when the air conditioner is powered off. The refrigerant leakage detection method for the air conditioner can detect whether the refrigerant leaks or not when the air conditioner is in the power-off state, so that the leakage can be timely found and the necessary measures can be taken, and the safety and reliability of the air conditioner are improved.

La présente invention concerne un procédé et un système de détection de fuite de fluide frigorigène pour un climatiseur, et le climatiseur. Le climatiseur comprend un module de détection et un module de stockage d'énergie. Le procédé de détection de fuite de fluide frigorigène pour un climatiseur comprend les étapes consistant à : détecter l'état d'alimentation du climatiseur ; et si le climatiseur est dans un état hors tension, commander le module de stockage d'énergie pour alimenter le module de détection en énergie, de telle sorte que le module de détection peut détecter en continu si un fluide frigorigène du climatiseur fuit ou non lorsque le climatiseur est hors tension. Le procédé de détection de fuite de fluide frigorigène pour le climatiseur peut détecter si le fluide frigorigène fuit ou non lorsque le climatiseur est dans l'état hors tension, de telle sorte que la fuite peut être trouvée en temps opportun et que les mesures nécessaires peuvent être prises, et la sécurité et la fiabilité du climatiseur sont améliorées.
