FIELD: machine building.SUBSTANCE: cryogenic heat exchanger cooling method and device, in which a programmable controller is used, which receives input signals representing signals of sensors, which characterise one or more controlled parameters in the chosen process, and generating commend signals for control of one or more controlled parameters in the chosen process. The programmable controller can perform a computer programme composed for a network containing at least three modules. Modules of the network are connected so that a start signal received by the second and the third modules of those, at least, three modules corresponds to a communication signal that is generated when the first module of those, at least, three modules has achieved the specified goal for that module.EFFECT: simpler control of a cooling process.22 cl, 7 dwg, 2 tbl |
