CRYOGENIC TRANSPORT OF TEMPERATURE-SENSITIVE PRODUCTS MAKING USE OF THE FUEL OPERATING THE VEHICLE ENGINE USING A EUTECTIC COLD STORAGE MODULE

摘要

The invention proposes a method for managing the operation of a refrigerated transport truck for thermosensitive products, of the indirect injection type of a cryogenic or refrigerant fluid in a main heat exchanger, the truck also comprising an additional heat exchanger (22). ), internal to the truck chamber, additional heat exchanger connected to other components for forming a heat exchange loop (20), a loop in which a cooling fluid circulates, and an evaporator for liquefied combustible gases evaporator adapted to receive fuel from the fuel reserve attached to the truck and able to heat exchange with said loop, said loop comprising a secondary heat exchanger (21) adapted to heat exchange with said evaporator, the secondary heat exchanger being connected by the loop to said additional exchanger, characterized in that the truck is equipped with a cold storage unit (50) of the eutectic plate type or of the type made of a so-called "phase change" material, which unit is located within said chamber, and in that when the engine of the truck is in operation and the chamber does not require a supply of cold, all or part of the cold generated during the vaporization of the fuel is stored in said cold storage unit for later use.
