Abstract
(EN)
An air conditioner, and a control method and device for a heating system thereof, wherein the method comprises: obtaining ambient temperature and external heat exchanger evaporation temperature; obtaining external heat exchanger evaporation pressure, and obtaining, according to the external heat exchanger evaporation pressure, corresponding saturation temperature; and controlling a base plate heating device (20) according to the ambient temperature, the external heat exchanger evaporation temperature, or the saturation temperature. Hence, the base plate heating device (20) is controlled according to the ambient temperature, the saturation temperature corresponding to the external heat exchanger evaporation pressure, or the external heat exchanger evaporation temperature, to avoid freezing of the base plate of an air conditioner, and ensure normal drainage of the base plate during defrosting, thereby improving the stability and reliability of the air conditioner.

L'invention concerne un climatiseur, et un procédé et un dispositif de commande destinés à un système de chauffage associé. Le procédé consiste : à obtenir une température ambiante et une température d'évaporation d'un échangeur de chaleur extérieur ; à obtenir une pression d'évaporation de l'échangeur de chaleur extérieur, et à obtenir, en fonction de la pression d'évaporation de l'échangeur de chaleur extérieur, une température de saturation correspondante ; et à commander un dispositif de chauffage (20) de plaque de base en fonction de la température ambiante, de la température d'évaporation de l'échangeur de chaleur extérieur, ou de la température de saturation. Par conséquent, le dispositif de chauffage (20) de plaque de base est commandé en fonction de la température ambiante, de la température de saturation correspondant à la pression d'évaporation de l'échangeur de chaleur extérieur, ou de la température d'évaporation de l'échangeur de chaleur extérieur, afin d'éviter la congélation de la plaque de base d'un climatiseur et d'assurer une évacuation normale de la plaque de base pendant le dégivrage, améliorant ainsi la stabilité et la fiabilité du climatiseur.
