Temperature control device and temperature control method

A temperature control method for controlling a temperature of an object whose temperature is to be controlled by means of a thermal fluid supplied by a fluid circulating and supplying system, wherein the fluid circulating and supplying system which circulates and supplies thermal fluid from and to the object whose temperature is to be controlled contains:

• first heat exchanging means for carrying out heat exchange with thermal fluid returning from the object whose temperature is to be controlled;
• second heat exchanging means located in a position leading from the first heat exchanging means to the object whose temperature is to be controlled, for carrying out heat exchange with thermal fluid passing therethrough;
• a bypass passage for splitting and supplying thermal fluid in the fluid circulating and supplying system from a position leading from the object whose temperature is to be controlled to the first heat exchanging means, to a position leading from the first heat exchanging means to the second heat exchanging means;
• and flow ratio regulating means for regulating a flow ratio between the thermal fluid passing through the first heat exchanging means and the thermal fluid passing through the bypass passage;
• the temperature control method comprising:
• output controlling step of detecting a temperature of the thermal fluid supplied to the object whose temperature is to be controlled and controlling an output of the second heat exchanging means on the basis of the detected temperature in such a manner that the thermal fluid supplied to the object whose temperature is to be controlled is adjusted to a prescribed set temperature;
• output detecting step of detecting the output of the second heat exchanging means after the output controlling step has been completed;
• and
• flow ratio controlling step of controlling the drive of the flow ratio regulating means, in cases where the detected output lies outside a previously determined output range, in such a manner that the output of the second heat exchanging means moves within the output range.
