Abstract

L'invention concerne un procédé de commande destiné à un climatiseur comprenant : l'acquisition d'un seuil de température extérieure et d'une condition de température d'alimentation en air ; l'acquisition, lorsque le climatiseur fonctionne en mode chauffage, d'une température extérieure, d'une température de machine extérieure et d'une température de radiateur ; lorsque la température extérieure n'est pas supérieure au seuil de température extérieure et que la température de machine extérieure n'est pas supérieure à une température de gel critique, le réglage du degré d'ouverture d'un premier dispositif d'étranglement (801) afin que la température du radiateur (7) satisfasse la condition de température d'alimentation en air. La présente invention concerne en outre un dispositif de commande destiné à un climatiseur et concerne un climatiseur. Ledit procédé peut commander un premier dispositif d'étranglement (801) devant être ouvert lorsqu'une température extérieure est inférieure à une température de gel critique, de sorte que les fluides réfrigérants s'écoulant vers l'extérieur d'un échangeur de chaleur d'une machine intérieure peuvent échanger de la chaleur avec un élément de commande électrique par l'intermédiaire d'un radiateur (7), ce qui permet d'augmenter la charge thermique des fluides réfrigérants fournis au moyen de la chaleur résiduelle générée par l'élément de commande électrique, de sorte que les fluides réfrigérants à chaleur échangée peuvent atteindre un état réfrigérant, requis par l'alimentation en air et l'augmentation d'enthalpie, d'un compresseur (3), ce qui améliore les performances de fonctionnement du compresseur (3).
