Claims (7)

  1. Appareil de climatisation (101) comprenant :
    un circuit de fluide frigorigène (102) dans lequel circule un fluide frigorigène dans un ordre d'un compresseur (119), d'un condenseur (115), d'un mécanisme de dilatation (117) et d'un évaporateur (116) ;
    un capteur de température de condensation (111) configuré pour détecter une température de condensation qui représente une température de fluide frigorigène dans le condenseur (115) ;
    une soufflante d'air (113) configurée pour réguler un volume d'air envoyé au condenseur (115) ;
    un dispositif de détection de charge de climatisation (125) configuré pour détecter une charge de climatisation ; et
    un dispositif de commande (130) configuré pour commander un volume d'air envoyé par la soufflante d'air (113), le dispositif de commande (130) présentant un premier mode utilisé pendant un fonctionnement normal et un second mode différent du premier mode en tant que modes de fonctionnement,
    dans le second mode, le dispositif de commande (130) étant configuré pour que la soufflante d'air (113) fonctionne afin de faire varier un volume d'air entre un premier volume d'air et un second volume d'air plus grand que le premier volume d'air avec variation de la température de condensation, et
    dans le premier mode, le dispositif de commande (130) étant configuré pour changer le mode de fonctionnement du premier mode au second mode lorsque la charge de climatisation détectée par le dispositif de détection de charge de climatisation (125) devient inférieure à une valeur seuil,
    dans le second mode, le dispositif de commande (130) étant configuré pour changer le mode de fonctionnement du second mode au premier mode lorsque la charge de climatisation devient supérieure à la valeur seuil, dans lequel
    dans le second mode, le dispositif de commande (130) est configuré pour changer un volume d'air envoyé par la soufflante d'air (113) du premier volume d'air au second volume d'air lorsque la température de condensation devient supérieure à une première température,
    et changer un volume d'air envoyé par la soufflante d'air (113) du second volume d'air au premier volume d'air lorsque la température de condensation devient inférieure à une seconde température inférieure à la première température.
  2. Appareil de climatisation selon la revendication 1, dans lequel
    le dispositif de détection de charge de climatisation (125) comprend
    un capteur de température de surface (110) configuré pour détecter une température de surface d'un objet situé dans un espace climatisé, et
    un capteur de température intérieure (121) configuré pour détecter une température intérieure, et
    le dispositif de commande (130) est configuré pour changer le mode de fonctionnement du second mode au premier mode lorsqu'au moins une parmi une première condition et une seconde condition est satisfaite durant des fonctionnements dans le second mode, la première condition étant une condition selon laquelle la température intérieure est inférieure à une première valeur seuil, et la seconde condition étant une condition selon laquelle la température de surface est inférieure à la seconde valeur seuil.
  3. Appareil de climatisation selon la revendication 1, dans lequel
    le dispositif de détection de charge de climatisation (125) détecte une vitesse de rotation du compresseur (119), et
    le dispositif de commande (130) est configuré pour changer le mode de fonctionnement du premier mode au second mode lorsque la vitesse de rotation du compresseur (119) devient inférieure à une première valeur seuil.
  4. Appareil de climatisation selon la revendication 1, l'appareil de climatisation comprenant une partie de changement de direction de vent (112) configurée pour changer une direction d'air envoyé par la soufflante d'air, dans lequel
    le dispositif de commande (130) est configuré pour commander la partie de changement de direction de vent (112) pour régler la direction d'air sur une direction de vent prescrite lorsque le mode de fonctionnement est le second mode.
  5. Appareil de climatisation selon la revendication 4, dans lequel
    un angle indiquant la direction de vent prescrite est supérieur ou égal à 45°, un angle indiquant une direction verticale à une surface de sol étant défini à 90° et un angle indiquant une direction horizontale à la surface de sol étant défini à 0°.
  6. Appareil de climatisation selon la revendication 1, l'appareil de climatisation comprenant en outre :
    un condenseur supplémentaire (115B) relié en parallèle au condenseur (115A) dans le circuit de fluide frigorigène ; et
    une soufflante d'air supplémentaire (113B) située en correspondance avec le condenseur supplémentaire (115B), dans lequel
    le dispositif de commande (130) est configuré pour commander la soufflante d'air (113A) et la soufflante d'air supplémentaire (113B) pour éviter un chevauchement d'une période durant laquelle la soufflante d'air (113A) envoie le second volume d'air avec une période durant laquelle la soufflante d'air supplémentaire (113B) envoie le second volume d'air dans le second mode.
  7. Appareil de climatisation selon l'une quelconque des revendications 1 à 6, dans lequel
    le premier volume d'air se rapporte à un volume d'air correspondant à un état selon lequel la soufflante d'air (113, 113A) est éteinte.
