Method and device for controlling the temperature of an object using heat transfer fluid

A device for controlling the temperature of an object using heat transfer fluid, comprising:

• a cooler/heater (6) for cooling or heating heat transfer fluid which is supplied to an object (5);
• a heating medium temperature sensor (10) for detecting the current temperature of the heat transfer fluid;
• an object temperature sensor (12) for detecting the current temperature of the object (5);
• and
• a controller (9) for outputting a manipulated variable in respect of the cooler/heater (6) by performing a feedback control operation using the current heating medium temperature (T1) from the heating medium temperature sensor and the current object temperature (Ts) from the object temperature sensor,
• wherein in the feedback control operation, the controller (9) determines a target temperature of the heating medium temperature (T1) so as to control the object temperature (Ts) to the desired temperature (SV), and determines the manipulated variable so as to control the heating medium temperature (T1) to this determined target temperature.
