Abstract:
The study is focused on the thermal performance analysis of a thermoelectric radiant heating panel (TERHP) system in a test chamber for cold climatic conditions. Three radiant panels with eight thermoelectric modules (TEM) each are installed on the three different walls of the study chamber to evaluate the performance of the panels to achieve the thermal comfort temperature inside the chamber of 1.2 * 1.2 * 2 m. All TEMs in a single TE panel of size 0.75 * 0.50 m are attached in a triangular arrangement to obtain a uniform temperature. The water block is used as a heat sink to maintain the temperature difference between the cold and hot sides of TEMs. The water circulation circuit with the "I" configuration has been used. Hot water at a constant temperature is supplied to the water block, and cold water obtained at the outlet is collected and circulated back after thermoregulation in a closed loop. The experiment is conducted by supplying inlet water at 18 C and applying operating voltages to the TERHP system of 12 V, 16 V, and 20 V. The surface temperature of panels, mean radiant temperature, operative temperature, air temperature, heating capacity, and coefficient of performance are measured on these inputs.
