1. A thermoelectric generation system comprising:
a thermoelectric element which generates power by a temperature difference;
a heating unit which includes a first heat medium path through which a heat medium passes, and heats the thermoelectric element by heat of the heat medium;
a cooling unit which cools the thermoelectric element;
a heat transfer unit which includes a second heat medium path through which the heat medium passes and which is connected to the first heat medium path, and heats, by using a heat source, the heat medium whose temperature is decreased as a result of heating the thermoelectric element;
a detection unit which detects a temperature of the heat source or a value that fluctuates according to the temperature of the heat source;
an adjustment unit which changes an amount of the heat medium which circulates through the first heat medium path and the second heat medium path; and
a control unit which controls the adjustment unit based on the value detected by the detection unit to adjust the amount of the heat medium,
a pressure holding container which stores the heat medium and holds a pressure of the heat medium that is being stored at a set value;
wherein the adjustment unit includes
a discharge valve which moves the heat medium in the first heat medium path to the pressure holding container only in one direction, and
a return valve which moves the heat medium in the pressure holding container to the first heat medium path only in one direction, and
wherein the discharge valve and the return valve are located in parallel between the pressure holding container and the heating unit.
