Abstract

L'invention concerne un système pour faire fonctionner plusieurs ensembles échangeurs de chaleur air-liquide couplés en parallèle, chacun des ensembles présentant au moins un ventilateur entraîné électriquement ainsi qu'une soupape à commande électrique montée dans le circuit de liquide, et la soupape pouvant être actionnée en premier lieu par au moins un thermostat. Selon l'invention, chaque ensemble échangeur de chaleur air-liquide dispose d'un dispositif de couplage additionnel qui superpose le processus de commutation primaire par thermostat et actionne et ferme la soupape concernée, dans le cas de n, avec n ≥ 2, ensembles échangeurs de chaleur air-liquide couplés en parallèle, en présence d'une surchauffe ou d'une surtempérature d'un des ensembles échangeurs de chaleur, due à des inclusions gazeuses, les ensembles échangeurs de chaleur restants étant fermés brièvement par actionnement du dispositif de commutation additionnel respectif, ce qui a pour effet d'induire une augmentation de la pression et de permettre d'éliminer les inclusions gazeuses.
