Abstract

L'invention concerne un procédé de régulation de température pour un conteneur réfrigéré. Le personnel peut ajuster la température cible d'un climatiseur à l'intérieur d'une première plage de température, et un dispositif de commande de climatiseur peut également ajuster automatiquement la température à l'intérieur de la première plage de température. Si le personnel ou le dispositif de commande de climatiseur a besoin de modifier la température cible à l'extérieur de la première plage de température du climatiseur pour être à l'intérieur d'une seconde plage de température, le personnel ou le climatiseur envoie des informations à une personne en charge et/ou à une plateforme de gestion et modifie la température cible du climatiseur uniquement après que la personne en charge et/ou la plateforme de gestion ont fourni une confirmation. Le procédé de régulation empêche la température d'un climatiseur de dispositif de levage d'être ajustée au-delà de la plage de réglage normal et empêche des opérations malveillantes ou des opérations erronées de faire dévier la température d'un conteneur réfrigéré par rapport à la température cible. L'invention concerne également un camion de restauration de compagnie aérienne électrique.
