Definitions

  • the pump can be operated at an operating point having a lower rotational speed, as required. Consequently, the amount of electric power consumed for the water supply can be reduced to achieve energy saving, leading to CO 2 reduction.
  • FIGS. 1 through 5 An embodiment of the present invention will be described in detail below with reference to FIGS. 3 through 5 .
  • identical or corresponding parts are denoted by identical reference numerals, and will not be described in duplication.
  • a small-flow-rate range energy-saving control head curve F that has a head lower than that of the standard control head curve B in a small flow rate range may be used to achieve energy saving primarily in the small flow rate range.
  • a plurality of small-flow-rate range energy-saving control head curves F having respective heads different from the standard control head curve B in the small flow rate range may be used to achieve stepwise energy saving.

Claims (5)

  1. Appareil d'alimentation en eau comprenant :
    une pompe (1) configurée pour mettre sous pression et distribuer de l'eau ;
    un convertisseur de fréquence (2) configuré pour fournir une alimentation électrique à la pompe (1) pour faire fonctionner la pompe (1) à une vitesse de rotation souhaitée ;
    un capteur de pression côté refoulement (4) configuré pour détecter une pression au niveau d'un côté refoulement de la pompe (1) ; et
    un contrôleur (15) configuré pour commander la vitesse de rotation de la pompe (1) ;
    dans lequel le contrôleur (15) est configuré pour stocker une pluralité de courbes de tête de commande (B, C1, C2, C3) représentant différentes relations entre des débits (Q) et des têtes (H), et est configuré pour commander la vitesse de rotation de la pompe (1) sur la base d'une courbe parmi les courbes de tête de commande (B, C1, C2, C3) sélectionnée de manière alternative ; caractérisé par :
    un panneau de commande (21) ayant un bouton de sélection (22) configuré pour commuter successivement la pluralité de courbes de tête de commande (B, C1, C2, C3) stockées dans le contrôleur (15) et un indicateur d'économie d'énergie (23) configuré pour indiquer des niveaux d'économie d'énergie correspondant aux courbes de tête de commande (B, C1, C2, C3) utilisées pour commander la vitesse de rotation de la pompe (1).
  2. Appareil d'alimentation en eau selon la revendication 1, dans lequel la pluralité de courbes de tête de commande (B, C1, C2, C3) comporte une courbe de tête de commande standard (B) et une courbe de tête de commande d'économie d'énergie de plage de faible débit (F), dont la tête est inférieure à celle de la courbe de tête de commande standard (B) dans une plage de faible débit.
  3. Appareil d'alimentation en eau selon la revendication 1 ou 2, dans lequel la pluralité de courbes de tête de commande (B, C1, C2, C3) comporte une courbe de tête de commande standard (B) et une courbe de tête de commande d'économie d'énergie de plage de débit moyen (D) dont la tête est inférieure à celle de la courbe de tête de commande standard (B) dans une plage de débit moyen.
  4. Appareil d'alimentation en eau selon l'une quelconque des revendications 1 à 3, dans lequel la pluralité de courbes de tête de commande (B, C1, C2, C3) comporte une courbe de tête de commande standard (B) et une courbe de tête de commande d'économie d'énergie de plage de fort débit (E), dont la tête est inférieure à celle de la courbe de la tête de commande standard (B) dans une plage de fort débit.
  5. Appareil d'alimentation en eau selon l'une quelconque des revendications 1 à 4, dans lequel la pluralité de courbes de tête de commande (B, C1, C2, C3) comporte une courbe de tête de commande standard (B) et une courbe de tête de commande d'économie d'énergie de plage de débit complet (C) qui s'étend sensiblement parallèlement à la courbe de tête de commande standard (B) et dont la tête est inférieure à celle de la courbe de tête de commande standard (B) dans une plage de débit complet.
