Vacuum freezing type ice slurry production using ethanol solution 2nd report: Investigation on evaporation characteristics of ice slurry in ice production in Revue internationale du froid, Vol 32, Issue 3 (2009)
[article]
Titre : Vacuum freezing type ice slurry production using ethanol solution 2nd report: Investigation on evaporation characteristics of ice slurry in ice production Titre original : Production de coulis de glace à l'aide d'une solution d'éthanol et d'un processus de refroidissement sous vide. 2e rapport : étude sur les caractéristiques d'évaporation du coulis de glace lors de la production de glace Type de document : texte imprimé Année de publication : 2012 Article en page(s) : pp. 394-401 Langues : Anglais (eng) Français (fre) Catégories : 621.5 : Technique pneumatique, du vide, des basses températures Mots-clés : Coulis de glace vide- éthanol COP - sublimation Index. décimale : 621.56 Technique des basses températures : réfrigération, pompe à chaleur Résumé : In this study, an original method for production of ice slurry from ethanol solution without using a refrigerator is proposed. As was introduced in the first report, this system has advantages compared with similar existing systems using materials other than ethanol solution. In this paper, the process of producing ice slurry using this method was observed, and the relationship between ethanol concentration of the solution and that of the vapor, which evaporated from the ice-solution mixture, was measured. It was found that the ethanol concentration of vapor was lower than that in the condition that did not produce ice. The composition of vapor was found to be affected by the sublimation of the ice produced. Finally, the COP of this system was estimated and the effect of sublimation of ice was investigated.
