METHOD OF MANAGING THE OPERATION OF A REFRIGERATED TRUCK FOR TRANSPORTING HEAT-SENSITIVE PRODUCTS BY MODIFYING THE REFRIGERATION POWER

摘要

A method for managing the operation of a refrigerated truck for transporting heat-sensitive products, of the indirect-injection type, in which the parameter ΔT=Tair inlet−Tsetpoint(Tair inlet: temperature of the air coming into contact with the heat exchanger internal to the truck as a result of the action of the fan, Tsetpoint: temperature to be set in the chamber inside the truck) is determined in real time and in which if ΔT is greater than an upper setpoint value ΔTsetpoint H, a rapid-pressurization (RMP) circuit is activated to vaporize some cryogen and thus increase the pressure in the head of gas above the reserve of cryogen of the truck.
