Abstract
(EN)
The invention provides an air conditioner current loop communication circuit and an air conditioner. A switching power supply module is provided and is connected in series onto a communication connection S line or an alternating current power connection line, so that direct current is supplied to the current loop communication loop. The invention uses the direct current output by the switching power supply to replace the existing resistor-based voltage divider direct current power supply circuit, and is compatible with air conditioner connection lines between indoors and outdoors in the existing current loop communication circuit. The problem of significant heating in existing resistor-based voltage divider circuits caused by large power consumption of a voltage-dividing resistor is thus solved, and the problem in which an existing voltage-dividing resistor is too bulky and not conducive to PCB board wiring is also solved.

L'invention concerne un circuit de communication de boucle de courant de climatiseur et un climatiseur. Un module d'alimentation à découpage est prévu et est connecté en série sur une ligne de connexion de communication en S ou une ligne de connexion d'alimentation en courant alternatif, de telle sorte qu'un courant continu est fourni à la boucle de communication de boucle de courant. L'invention utilise la sortie de courant continu de l'alimentation à découpage afin de remplacer le circuit d'alimentation en courant continu diviseur de tension à base de résistance existant, et est compatible avec des lignes de connexion de climatiseur entre l'intérieur et l'extérieur dans le circuit de communication de boucle de courant existant. Le problème de chauffage significatif dans les circuits diviseurs de tension à base de résistance existants provoqué par une grande consommation d'énergie d'une résistance de division de tension est ainsi résolu, et le problème selon lequel une résistance de division de tension existante est trop volumineuse et n'est pas conductrice vers un câblage de carte PCB est également résolu.
