Abstract
A drive circuit of a temperature adjustment apparatus drives a Peltier element at a desired output amount. A state detector detects an electrical state of the Peltier element. A control circuit calculates a desired output amount based at least on the electrical state of the Peltier element, determines a control quantity for driving the Peltier element at the desired output amount, and controls the drive circuit at the control quantity.
