Abstract

Un procédé de gestion du fonctionnement d'un camion de transport frigorifique de produits thermosensibles, du type à injection indirecte, où le camion est muni : - d'au moins une chambre de stockage des produits, - d'une réserve d'un fluide cryogénique tel l'azote liquide ou le CO2 liquide, - d'un système d'échangeur thermique dans lequel circule le fluide cryogénique, système d'échangeur comprenant au moins un échangeur thermique interne à ladite au moins une chambre, - ainsi que d'un système de circulation d'air, par exemple de type ventilateurs, apte à mettre en contact l'air interne à la chambre avec les parois froides du ou des échangeurs interne(s) à ladite au moins une chambre ; se caractérisant en ce que l'on ordonne une opération de dégivrage dudit échangeur par la prise en compte de la pente de descente de la température de reprise d'air de l'échangeur Tint et de l'écart de température entre la température de reprise d'air de l'échangeur Tint et une valeur de consigne visée pour la température à l'intérieur de ladite au moins une chambre, Consint.A method for managing the operation of a refrigerated transport truck for thermosensitive products of the indirect injection type, in which the truck is provided with: at least one product storage chamber, a fluid reservoir cryogenic such as liquid nitrogen or liquid CO2, - a heat exchanger system in which the cryogenic fluid circulates, exchanger system comprising at least one heat exchanger internal to said at least one chamber, - as well as an air circulation system, for example of the type fans, able to put the internal air in contact with the chamber with the cold walls of the exchanger (s) internal (s) at said at least one chamber; characterized in that a defrosting operation of said exchanger is ordered by taking into account the slope of descent of the air intake temperature of the exchanger Tint and the temperature difference between the rework temperature of the heat exchanger Tint and a target setpoint for the temperature within said at least one chamber, Consint.
