Abstract

L'invention concerne un circuit de fluide de refroidissement pour un moteur à combustion interne, comprenant une machine de compression pour un air d'admission. Ledit circuit de fluide de refroidissement est constitué d'un circuit à haute température et d'un circuit à basse température. Le circuit à haute température sert à refroidir le moteur à combustion interne au moyen d'un système de refroidissement du fluide de refroidissement et d'une première pompe de fluide de refroidissement disposée dans le circuit à haute température. Le circuit à basse température doté d'une deuxième pompe de fluide de refroidissement sert à refroidir l'air d'admission comprimé par la machine de compression au moyen d'un système de refroidissement de l'air de charge, et à refroidir un agent réfrigérant d'un circuit réfrigérant dans un condenseur. Le circuit à haute température et le circuit à basse température sont des circuits de refroidissement séparés l'un de l'autre. La configuration selon l'invention permet de réduire la charge de base thermique du circuit à basse température, et donc de réduire le niveau de pression dans le circuit réfrigérant, ce qui se traduit positivement par une réduction de la consommation d'énergie.
