Claim 0:
1. A temperature adjustment system, comprising:
a heat exchange unit;
a chiller device;
a heating device;
a temperature detection device; and
a control device,
wherein the heat exchange unit is configured to perform heat exchange using a coolant and is disposed inside a placing table, on which a target object is placed, and equipped with multiple heat exchange chambers,
the multiple heat exchange chambers are disposed in multiple regions, respectively, set on the placing table,
the multiple regions are set along a placing surface of the placing table,
the chiller device is configured to circulate the coolant with respect to the multiple heat exchange chambers,
the temperature detection device includes multiple temperature detectors,
the multiple temperature detectors are disposed in the multiple regions, respectively, and disposed between the respective multiple heat exchange chambers and the placing surface, and
the control device is configured to control the chiller device to adjust a pressure of the coolant such that a temperature of the placing table reaches a first temperature range, and then, control the chiller device to individually adjust flow rates of the coolant supplied to the multiple heat exchange chambers, respectively, such that all of temperatures measured by the multiple temperature detectors reach the first temperature range.
