Abstract

This article ascribes about the thermoelectric module that conveniently creates the difference temperature between the both of its sides by supplying the electricity. The study aims to test the performance of the heat generating and heat exchanging capability of the thermoelectric module model TEC-12710 for the possibility evaluation when it will be modified in the agricultural products drying system. The experiment apparatus was prepared by install the air fin heat exchangers on the 16 cm2 of both sides of the thermoelectric module and then, enforced the air flow through the system and measured the inlet-outlet of air properties. The results found that the supplying of 16 V, 8.5 A DC electricity to the module gains the air temperature from 30°C 68%RH to 52.3°C 26.8%RH on the hot side of the module. The system consumes a 40 W of power and gives the highest moisture extraction rate (MER) at 0.016 kgwater/h on the cold side of module by supplying of 6 V 3.5 A and it have the coefficient of performance (COP) at 1.14. It is possible to adapt this module with the drying system especially the heat pump drying system.
