Due to the compressor 42 during heating The pipeline does not work, and the condenser 43 does not frost, so that the electric heating consumes 10%-30% less energy than the compressor 42. That is, the energy consumption for heating is lower than that by the compression and release principle of the refrigerant.

Abstract

La présente invention concerne un procédé et un dispositif de commande d'un climatiseur et le climatiseur. Le procédé comprend : l'acquisition d'une température cible intérieure, de la température intérieure et de la température extérieure; la comparaison de la température intérieure avec la température cible intérieure pour produire un premier résultat de comparaison et un second résultat de comparaison; en réponse au premier résultat de comparaison, l'identification si un premier mode est actuellement actif; si non, l'exécution : le marquage du mode actuel en tant que second mode, et la commande, sur la base du résultat de comparaison de la température intérieure et de la température extérieure, de l'entrée dans un mode d'air frais ou dans un mode de chauffage; en réponse au second résultat de comparaison, l'identification si le second mode est actuellement actif; si non, l'exécution : le marquage du mode actuel en tant que premier mode, et la commande, sur la base du résultat de comparaison de la température intérieure et de la température extérieure, de l'entrée dans un mode d'air frais ou dans un mode de refroidissement. De l'air frais extérieur peut être complètement utilisé dans le refroidissement et le réchauffage de l'air intérieur sur la base de la satisfaction des exigences en termes de refroidissement et de chauffage, ce qui permet de réduire considérablement la consommation d'énergie, de réaliser des économies d'énergie et de réduire les émissions.
