Abstract

L'invention concerne une installation frigorifique à sous-refroidissement régulé, obtenue par insertion d'un échangeur de chaleur sur la conduite de liquide afin d'augmenter le sous-refroidissement. L'échangeur peut réaliser un échange de chaleur au moyen d'eau, d'air ou d'un autre fluide frigorigène. Les avantages obtenus varient en fonction de la solution adoptée : refroidissement hybride air + eau; récupération de chaleur en deux étapes; récupération de chaleur à basse température par post-chauffage; auto-stockage d'énergie frigorifique; sous-refroidissement régulé à circuit frigorifique spécialisé.
