Abstract

L'INVENTION CONCERNE UN SYSTEME DE REFRIGERATION A DEGIVRAGE RAPIDE. ELLE SE CARACTERISE EN CE QU'UNE VANNE 17 ARRETE L'ECOULEMENT DE LIQUIDE REFRIGERANT VERS L'EVAPORATEUR 13 ET EN CE QU'ON FAIT ALORS CIRCULER LE SEUL FLUIDE REFRIGERANT CONTENU DANS L'EVAPORATEUR SUR UNE UNITE DE RECHAUFFAGE 25 A STOCKAGE THERMIQUE. APPLICATION: LYOPHILISATION.THE INVENTION RELATES TO A QUICK DEFROST REFRIGERATION SYSTEM. IT IS CHARACTERIZED IN THAT A VALVE 17 SHUT OFF THE FLOW OF REFRIGERANT LIQUID TOWARDS THE EVAPORATOR 13 AND THEN IS THEN CIRCULATED THE ONLY REFRIGERANT FLUID CONTAINED IN THE EVAPORATOR ON A HEATING UNIT 25 WITH THERMAL STORAGE. APPLICATION: LYOPHILIZATION.
