Abstract

Le problème décrit par la présente invention est de fournir un système de gestion de chaleur apte à réguler efficacement la température à faible coût pour un sujet dont la température doit être régulée lors de la régulation de la température par circulation d'un milieu chauffant à travers le sujet dont la température doit être régulée et qui est également apte à résoudre les problèmes associés à un écart du milieu chauffant. La solution selon la présente invention comprend : un circuit de régulation de température (42) qui comprend une troisième pompe (23) pour faire circuler un milieu chauffant à travers une batterie (2) ; un circuit de milieu chauffant à haute température (44) qui amène un milieu chauffant chauffé par une unité de chauffage (14) destinée à chauffer celui-ci à circuler ; un circuit de milieu chauffant à basse température (43A) qui amène un milieu chauffant refroidi par une unité de refroidissement (13) destinée à refroidir celui-ci à circuler ; des thermovannes (31 et 30) qui introduisent sélectivement le milieu chauffant s'écoulant à travers le circuit de milieu chauffant à haute température (44) et le milieu chauffant s'écoulant à travers le circuit de milieu chauffant à basse température (43A) dans le circuit de régulation de température (42) ; et une unité de stockage (26) qui est disposée sur un trajet à travers lequel le milieu chauffant est renvoyé du circuit de régulation de température (42) au circuit de milieu chauffant à haute température (44) ou au circuit de milieu chauffant à basse température (43A), et qui stocke le milieu chauffant.
