Abstract: The invention relates to a method for managing the supply of cryogenic liquid to a truck 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, generally closed, is placed upstream from the heat-exchanger system; a proportional analog valve, generally open, is placed downstream from the heat-exchanger system; and a downstream two-position valve, generally open, is placed downstream from the analog valve.

Abstract: The invention relates to a process for controlling at least two production units whose outputs are connected in parallel in order to produce a common output flow which is intended to feed a consumer plant. It controls the common output flow as a function of a predetermined target value (u) and includes the steps consisting in measuring at least one variable representing the common output flow; for each unit, determining a control instruction corresponding to one operating state of the unit among a finite set of predetermined operating states; and controlling the units with the control instructions determined. Two variables representing the common output flow are measured and the control instructions are determined by a fuzzy-logic controller. Application to controlling a set of compressors.
