Title:
THERMOELECTRIC GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/216426
Kind Code:
A1
Abstract:
A thermoelectric generation system (1) is provided with: a thermoelectric element (11); a heating unit (12); a cooling unit (13); a heat transfer unit (21); a pressure gauge (42); a first valve (31); and a control unit. The thermoelectric element (11) uses a temperature difference to generate power. The heating unit (12) has a first heat medium path through which a heat medium passes, and heats the thermoelectric element (11) by means of the heat of the heat medium. The cooling unit (13) cools the thermoelectric element (11). The heat transfer unit (21) has 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 reduced in temperature as a result of heating the thermoelectric element (11). The pressure gauge (42) detects the rise or fall of a value (pressure of heat medium) in accordance with the temperature of the heat source. The first valve (31) changes the amount of the heat medium circulating through the first and second heat medium paths. The control unit adjusts the amount of the heat medium by controlling the first valve (31) on the basis of the value detected by the pressure gauge (42).
