CONTROL METHOD FOR ORGANIC RANKINE CYCLE Russian patent published in 2019 - IPC F01K13/02 

FIELD: machine building.

SUBSTANCE: invention relates to power engineering. Method is disclosed for controlling an organic Rankine cycle system, comprising at least one feed pump, at least one heat exchanger, an expansion turbine and a condenser, the organic Rankine cycle comprising a feeding phase of an organic working fluid, a heating and vaporisation phase of the same working fluid, an expansion and condensation phase of the same working fluid, wherein said method controls an adjusted variable (X), which is a function of an overheating of the organic fluid, by means of a controller that acts by varying a control variable (Y), which is a parameter of the organic fluid in its liquid phase, and wherein the adjusted variable (X) is a temperature difference (ΔT) between a current temperature of the organic fluid in vapour phase at the turbine inlet and a temperature threshold (T_lim), under which the expansion phase involves the formation of a liquid phase of the organic fluid.

EFFECT: invention improves the efficiency of the system.
