Title
(EN) REFRIGERATION AND FREEZING PLANT
(FR) INSTALLATION DE REFRIGERATION ET DE CONGELATION
Abstract
(EN)
A cooling and freezing plant includes at least one cooling space (34) and at least one freezing space (36), said spaces being connected to a central unit (20). The central unit is connected for indirect cooling of the cooling space (34) by means of a cold transfer medium which is cooled in the unit and, besides being conducted to the cooling space, is also conducted to a condenser (38) in a local cooling unit (40) arranged in connection with and for the freezer cabinet (36).
(FR)
Une installation de réfrigération et de congélation comprend au moins un espace pour la réfrigération (34) et au moins un espace pour la congélation (36), lesdits espaces étant reliés à une unité centrale (20). L'unité centrale est connectée pour permettre le refroidissement indirect de l'espace de réfrigération (34) par l'intermédiaire d'un milieu de transfert du froid, refroidi dans ladite unité. Le milieu de transfert est conduit vers l'espace de réfrigération ainsi que vers un condenseur (38) disposé dans une unité de réfrigération locale (40) aménagée pour le congélateur (36) et reliée à celui-ci.
