The invention refers to a system for cooling a process fluid of a heat-producing apparatus, comprising: an outlet of the heat-producing apparatus, the outlet being provided for discharging process fluid to be cooled from the heat-producing apparatus; an inlet of the heat-producing apparatus, the inlet being provided for supplying cooled process fluid to the heat-producing apparatus; and a thermodynamic cycle device, in particular an ORC device, the thermodynamic cycle device comprising an evaporator having an inlet for supplying the process fluid to be cooled from the outlet of the heat-producing apparatus and having an outlet for discharging the cooled process fluid to the inlet of the heat-producing apparatus, the evaporator being adapted to evaporate a working medium of the thermodynamic cycle device by means of heat from the process fluid; an expansion machine for expanding the evaporated working medium and for producing mechanical and/or electrical energy; a condenser for liquefying the expanded working medium, in particular an air-cooled condenser; and a pump for pumping the liquefied working medium to the evaporator.

ORC device for cooling a process fluid

The invention relates to a method for controlling ORC stacks with a total number nof individually operable ORC modules, said method comprising the following steps: determining the running time remaining until the next servicing time for each operable ORC module respectively; determining a target number nof ORC modules to be operated; comparing said target number nto an actual number nof currently operated ORC modules; when n&#x3e;n, connecting a number n&#x2212;nof ORC modules that corresponds to the difference between the target number and the actual number, where the ORC modules with the longest remaining running times of the ORC modules currently not being operated are connected; and/or when n&#x3c;n, disconnecting a number n&#x2212;nof ORC modules that corresponds to the difference between the actual number and the target number, where the ORC modules with the shortest remaining running times of the ORC modules currently being operated are disconnected; and/or when n=n, connecting the ORC module with the longest remaining running time &#x394;tof the ORC modules not currently being operated, and disconnecting the ORC module with the shortest remaining running time &#x394;tof the ORC modules currently being operated, if &#x394;t&#x3e;&#x394;t.
