DESIGN AND FABRICATION OF THERMOELECTRIC SOLID-STATE AIR CONDITIONER

Abstract

In this study, we designed and fabricated of thermoelectric solid-state air conditioner (TESSAC) within 400 BTU/hour by using a thermoelectric cooling (TEC) module (model: TEC1-12710) for 3 modules. Thermal management was carried out with the aluminum water-to-radiator system through the liquid moly coolant for controlling the temperature on the hot side of the TEC module. The cooling performance and electrical power were measured during the operating system as performed in one cubic meter for 3 h. According to the experimental results, the TEC1-12710 of one module could be generated cooling by decreasing the temperature to -8.5oC. After useful TEC of 3 modules as useful TESSAC fabrication, TESSAC could be cooled at the cold side around 9.3°C, then the temperature at the center simulation room is around 27.5°C within the ambient temperature of 33.5°C. The coefficient of performance (COP) of TESSAC was calculated to be obtained around 5.5 with the AC power used of 202.31 W.
