Abstract

La présente invention concerne un appareil, comprenant un système de pompage hydronique sans capteur, qui comporte un processeur de signaux ou un module de traitement de signaux configuré pour recevoir une signalisation contenant des informations concernant des valeurs de lecture de puissance et de vitesse de moteur, et également concernant des équations caractéristiques de pompe et de système conjointement avec des équations de puissance empiriques qui sont construites par une fonction polynomiale à meilleur ajustement conjointement avec des lois d'affinité de pompe sur la base d'une courbe de pompe publiée par un fabricant de pompe ; et déterminer une signalisation correspondante contenant des informations concernant la pression d'une pompe ou d'un système et un débit au niveau des valeurs de lecture de puissance et de vitesse du moteur sur la base de la signalisation reçue.
