Temperature control device

A temperature control device that controls a temperature of a medium circulated through an object via a pipeline, the device comprising:

• a first medium circulating portion that circulates the medium via a first pipeline;
• a second medium circulating portion that circulates the medium via a second pipeline;
• a third medium circulating portion that circulates the medium via a third pipeline;
• a switching portion that switches the medium circulated through the object by selecting any one of the first pipeline, the second pipeline and the third pipeline;
• a single pressurization pump that can apply a required pressure to the first pipeline, the second pipeline, and the third pipeline through a pressure pipe communicating with each of the first pipeline, the second pipeline and the third pipeline, wherein the pressurization pump communicates with the pressure pipe, and
• the pressure pipe branches into three branched pressure pipes that communicate directly with the first pipeline, the second pipeline and the third pipeline, respectively.
