Comparison Power Generation by Using Thermoelectric Modules between Cooling Module and Power Module for Low Temperature Application

摘要

The paper presents comparison thermoelectric power generation between cooling and power modules. In order to investigate which type of TE module is suitable for the power generation at low temperature of hot side of TE, four TE modules were considered: two TE cooling modules (TE model TEC1-12708 and MT2-1.-127) and two TE power modules (TE model TEP1-1264-3.4 and TEG1-1260-5.1) for by investigation temperature between 25 to 230°C and resistance were 0, 5, 10, 15 and 20 Ohm. The results of this research found that thermoelectric model TEC1-12708 could be the highest power generation about 0.98 watt and energy cost about 3-11 Bath/kWh (0.09-0.35 USD/kWh) depend on resistance of load, consequently thermoelectric cooling module was be proper to generated electric current at low temperature.
