Abstract

Un conteneur de réfrigération et un dispositif de commande de l'isolation au froid du conteneur de réfrigération. Dans une réalisation du conteneur de réfrigération, l'intérieur du conteneur est délimité dans une chambre avant (2A) sur une paroi avant et une chambre arrière (2B) sur une paroi arrière par une cloison (13) installée dans le conteneur (2), la chambre avant (2A) est réglée sur une température basse et la chambre arrière (2B) est réglée sur une température élevée. La chambre avant (2A) est refroidie par une unité de réfrigération (3) et la chambre arrière (2B) est refroidie par l'apport d'un air froid dans la chambre arrière (2B). L'unité de réfrigération (3) comprend un moteur primaire, un générateur dirigé par le moteur primaire et un dispositif de réfrigération pourvu d'un compresseur électrique dirigé par une énergie électrique générée par le générateur. Un chauffage électrique (20) est installé dans la chambre arrière (2B).
