Title (EN) AIR CONDITIONER AND METHOD FOR CONTROLLING THE SAME
(FR) CLIMATISEUR ET PROCÉDÉ DE COMMANDE DE CELUI-CI
Abstract:
(EN) An air conditioner and a method for controlling the same are disclosed. The air conditioner implements a multistage expansion scheme by implementing serial connection between electronic expansion valves including in the R410A refrigerant-based air conditioner, and thus guarantees an optimum compression ratio in all cooling/heating load regions. Although cycle characteristics are changed by changing R410A refrigerant to R32 refrigerant, the air conditioner optimizes the cycle simply by controlling a degree of opening of electronic expansion valves, respectively. Since the cycle optimization is implemented using the multistage expansion scheme in which legacy electronic expansion valves are coupled in series, the design modification is minimized without design modification of requisite constituent elements such as a heat exchanger, system implementation is facilitated, resulting in high efficiency in cost and productivity. Cooling/heating performance improvement and reliability guarantee are achieved under all load conditions, resulting in increased system efficiency.
(FR) La présente invention concerne un climatiseur et un procédé de commande de celui-ci. Le climatiseur met en œuvre un schéma d'expansion à plusieurs étages en mettant en œuvre une connexion en série entre des vannes d'expansion électroniques comprenant dans le climatiseur à base de réfrigérant R410A, et garantit ainsi un taux de compression optimal dans toutes les régions de charge de refroidissement/chauffage. Bien que les caractéristiques de cycle soient modifiées en changeant le réfrigérant R410A pour un fluide frigorigène R32, le climatiseur optimise le cycle simplement par contrôle d'un degré d'ouverture de valves d'expansion électroniques, respectivement. Étant donné que l'optimisation de cycle est mise en œuvre à l'aide du schéma d'expansion à étages multiples dans lequel des vannes d'expansion électronique existantes sont couplées en série, la modification de conception est minimisée sans modification de conception des éléments constitutifs requis tels qu'un échangeur de chaleur, la mise en œuvre du système est facilitée, ce qui permet d'obtenir une efficacité élevée en termes de coût et de productivité. L'amélioration de la performance de refroidissement/chauffage et la garantie de fiabilité sont obtenues dans toutes les conditions de charge, ce qui résulte en une augmentation de l'efficacité du système.
