Abstract (en)
[origin: WO2012080600A1] The invention relates to a method for managing the supply of cryogenic liquid to a truck (20) for transporting heat-sensitive materials, said truck implementing a method using said cryogenic liquid to transfer negative calories to the materials. Said method is a so-called indirect-injection method in which the liquid is fed into a heat-exchanger system located inside the truck, where said liquid evaporates. The transfer of cold to the materials is achieved by means of an exchange between the atmosphere surrounding the materials and the cold walls of the heat-exchanger system, characterized in that the heat-exchanger system is supplied with cryogenic liquid by implementing the following measures: an upstream two-position valve (1), generally closed, is placed upstream from the heat-exchanger system; a proportional analog valve (10), generally open, is placed downstream from the heat-exchanger system; and a downstream two-position valve (11), generally open, is placed downstream from the analog valve.
