Method and system for controlling the temperature of components

A method for controlling the temperature of a component (4) using a temperature-control system;

• wherein the temperature-control system (1′) comprises:
• a temperature-control device (3), which is implemented for heating or cooling a temperature-control fluid (2);
• 2 to n temperature-control arrangements (5,5′) for conducting the temperature-control fluid (2) through the component (4) to be controlled in temperature, wherein the 2 to n temperature-control arrangements (5,5′) are connected via a common supply line (6) to the temperature-control device (3) to supply the temperature-control fluid (2);
• 2 to n return lines (7,7′) for returning the temperature-control fluid (2) from the 2 to n temperature-control arrangements (5,5′) to the temperature-control device (3);
• 2 to n return temperature sensors (12,12′), wherein each return temperature sensor (12,12′) is arranged on or in one of the return lines (7,7′) and a supply temperature sensor (11) is arranged on or in the common supply line (6);
• 2 to n valves (9,9′), which are each equipped with an actuator (10,10′) and which are each inserted in a separate supply line (6′,6″) after a supply manifold (23) or are each inserted in one of the return lines (7,7′) before an optional return manifold (23′), wherein the actuators (10,10′) are implemented to set a degree of opening of the respective valve (9,9′), and wherein a control module (8) is implemented to activate the actuators (10,10′);
• wherein a regulator (13) of the control module (8) registers the respective temperature differences between the common supply temperature registered by the supply temperature sensor (11) and the 2 to n individual return temperatures of the temperature-control fluid (2) registered by the return temperature sensors (12, 12′),
• wherein, using the regulator (13) of the control module (8), an individual temperature difference between the supply temperature and each one of the 2 to n return temperatures of the temperature-control fluid (2) is registered in each case, and
• wherein the regulator (13), proceeding from these individual temperature differences, causes the actuators (10,10′) of the 2 to n valves (9,9′) to set the degree of opening of these valves (9,9′) in such a manner that the individual mean temperature differences between the supply temperature and the respective return temperature of the temperature-control fluid (2) are each in a predetermined value range.
