Abstract
A temperature adjustment device includes: at least one first Peltier unit having a heat absorption surface and a heat release surface; at least one second Peltier unit having a heat absorption surface and a heat release surface; a controller which controls the drive currents of the first Peltier unit and the second Peltier unit; a primary circulation mechanism which circulates a primary refrigerant between a first heat release block and a heat absorption block; at least one second heat release block which has a flow path through which a secondary refrigerant flows, receives heat from the heat release surface of the second Peltier unit and transmits the heat to the secondary refrigerant; a heat exchanger which receives the secondary refrigerant discharged from the second heat release block and releases heat; and a secondary circulation mechanism which circulates the secondary refrigerant between the second heat release block and the heat exchanger.
