Title
(EN) AIR CONDITIONER, AND CONTROL METHOD AND DEVICE THEREFOR
(FR) CLIMATISEUR, SON PROCÉDÉ ET SON DISPOSITIF DE COMMANDE

Abstract
(EN)
Disclosed are an air conditioner, and a control method and device therefor. The method comprises the following steps: acquiring a first refrigerant concentration of an indoor refrigerant; and when it is detected and determined that the first refrigerant concentration is greater than a first concentration threshold, controlling a fresh air system to start. According to the method, when it is detected that a first refrigerant concentration of an indoor refrigerant is greater than a first concentration threshold, a fresh air system is controlled to start so as to accelerate air circulation between indoors and outdoors, thereby discharging the indoor refrigerant outdoors, reducing the refrigerant concentration indoors and thus improving the indoor air quality.

L'invention concerne un climatiseur, son procédé et son dispositif de commande. Le procédé comprend les étapes suivantes consistant : à acquérir une première concentration de fluide frigorigène d'un fluide frigorigène intérieur ; lorsqu'il est détecté et déterminé que la première concentration de fluide frigorigène est supérieure à un premier seuil de concentration, à amener un système d'air frais à démarrer. Selon le procédé, lorsqu'il est détecté qu'une première concentration de fluide frigorigène d'un fluide frigorigène intérieur est supérieure à un premier seuil de concentration, un système d'air frais est amené à démarrer de façon à accélérer la circulation de l'air entre l'intérieur et l'extérieur, moyennant quoi le fluide frigorigène intérieur est évacué vers l'extérieur, la concentration de fluide frigorigène à l'intérieur est réduite et la qualité de l'air intérieur est améliorée.
