Abstract

Des compresseurs (1) alimentent un condenseur à air (4) principal suivi d'un échangeur thermique indirect (6), un réservoir de liquide (8) et un second échangeur thermique indirect (10) fonctionnant en tant que sous-refroidisseur de fluide frigorigène. Une pompe (12) fournit du fluide frigorigène sous-refroidi à des dispositifs de réfrigération à distance (15, 18), une conduite de dérivation (19) permettant de remettre dans le circuit une proportion du fluide frigorigène à travers le sous-refroidisseur (10), ce qui permet de maintenir un écoulement de fluide frigorigène dans le réseau de distribution même en l'absence de demande de réfrigération. Les canalisations de distribution et de retour sont incluses dans un environnement thermique commun développé par une gaine d'isolation thermique (14). Des circuits de réfrigération secondaires (21) fonctionnent hors pointe de manière à créer un coulis de glace pouvant être pompé dans une réserve à glace (23) qui est utilisée pour réfrigérer l'échangeur thermique indirect (6). L'échangeur thermique (6) fonctionne en tant que condenseur supplémentaire dans des conditions d'ambiance chaudes. Cette invention concerne également des systèmes dans lesquels le réservoir à glace est supprimé et remplacé par un échange thermique direct entre les systèmes de réfrigération primaire et secondaire, lesquels systèmes (15, 18) étant alimentés par l'intermédiaire d'une boucle de réfrigération contenant un milieu d'échange thermique exempt d'hydrocarbures indirectement refroidi.
