Title (EN) SYSTEMS AND METHODS FOR DETECTING DEGRADATION OF A COMPONENT IN AN AIR CONDITIONING SYSTEM
(FR) SYSTÈMES ET PROCÉDÉS DE DÉTECTION DE DÉGRADATION D'UN COMPOSANT D'UN SYSTÈME DE CONDITIONNEMENT D'AIR
Abstract:
(EN) A method including: determining whether a cooling system is operating in a cooling mode, such that the cooling system is not operating in a reheat mode, a humidification mode or a dehumidification mode; determining whether the cooling system is operating in a compressor mode, such that the cooling system is not operating in a pump refrigerant economization mode; determining whether the cooling system is at steady-state; and if the cooling system is operating in the cooling mode and the compressor mode and is at steady-state, evaluating one or more rules to determine if a degradation symptom exists for the cooling system. The method further includes: subsequent to the evaluation, generating a degradation evaluation value to indicate whether the one or more rules are satisfied; and based on the degradation evaluation value, generating an alarm signal or performing a countermeasure.
(FR) L'invention concerne un procédé consistant à : déterminer si un système de refroidissement fonctionne en mode de refroidissement, de sorte que le système de refroidissement ne fonctionne pas en mode de réchauffage, en mode d'humidification ou en mode de déshumidification ; déterminer si le système de refroidissement fonctionne en mode compresseur, de sorte que le système de refroidissement ne fonctionne pas en mode d'économie de fluide frigorigène de pompe ; déterminer si le système de refroidissement est en régime permanent ; et, si le système de refroidissement fonctionne en mode de refroidissement et en mode compresseur et qu'il se trouve en régime permanent, évaluer une ou plusieurs règles de façon à déterminer si un symptôme de dégradation existe en ce qui concerne le système de refroidissement. Le procédé consiste en outre à : après l'évaluation, générer une valeur d'évaluation de dégradation pour indiquer si la ou les règles sont satisfaites ; et, sur la base de la valeur d'évaluation de dégradation, générer un signal d'alarme ou prendre une contre-mesure.
