Abstract

L'invention concerne un système de régulation de température capable de supprimer la consommation d'énergie et la surchauffe inutiles d'un ou d'une pluralité de sujets dont la température doit être régulée en faisant atteindre par la température des sujets une température cible avec précision dans un temps spécifié. En se basant sur un temps d'entrée, une température cible, la valeur de sortie maximale d'une unité de réglage de température (3), un temps d'augmentation de température, c'est-à-dire un temps nécessaire pour un sujet dont il faut réguler la température (4) pour atteindre la température cible, et un facteur de charge stabilisé dans le temps, c'est-à-dire un facteur de charge au moment où le sujet à réguler (4) se trouve dans un état stabilisé après avoir terminé l'augmentation de température, une unité de calcul de limiteur de sortie (2) calcule : une valeur de limiteur de sortie qui est le rapport entre la quantité de chaleur à appliquer dans le but que la température du sujet (4) atteigne la température cible dans le temps d'entrée, et la valeur de sortie maximale de l'unité de réglage de température (3). L'unité de réglage de température (3) règle le produit de la valeur de limiteur de sortie et la quantité maximale de fonctionnement en tant que valeur limite supérieure de la sortie, et régule le sujet dont la température doit être régulée (4) pour qu'elle soit à la température cible.
