Diagrammes enthalpiques de phase et le principe du balancier : outils permettant de décrire les diverses conditions gouvernant le comportement des coulis de glace.

Enthalpy-phase diagrams and the seesaw principle: aids to describe various ice slurry conditions.

Auteurs : MELINDER Å., HÄGG C.

Résumé

Most water solutions used as single-phase secondary fluid in indirect refrigeration systems can also be used as ice slurry, a fluid consisting of liquid and ice where the ice crystals are produced with the aid of an ice generator. The ice slurry is then distributed to the cooling object where the fluid takes up heat as ice crystals melts. One of the main purposes of this technology is to benefit from the great enthalpy change during the melting of ice. This gives less temperature change in the cooling object, makes it possible to decrease the volume flow for a given cooling capacity and to use smaller pipe dimensions in the system.
