Performance Evaluation of TEC1-12706 Thermoelectric Cooler Module at Low Temperature Experimentally

Thermoelectric is an alternative cooling device over vapor compression refrigeration system. Due to its more environmentally friendly and compact nature. Thermoelectric has two sides that functions as a hot reservoir and cold reservoir, and utilizes electrical energy to pump heat. In this research, testing of the thermoelectric coolant heat of TEC1-12706 at low temperature was carried. The low temperature below the ambient temperature was arrange, to obtain the value of cooling capacity and the performance coefficient at low temperature. There were three parameters measured, which were current, voltage, and temperature. The hot side temperature of TEC1-12706 was kept below the ambient temperature by placing the hot side on the cold plate of the evaporator vapor compression refrigeration system. The results shows that the performance coefficient value and cooling capacity are increasing as the input power value increases in TEC1-12706. The value of Cooling Capacity is between 0.24 to 2.96 watt; while the value of COP is between 0.56 to 1.05. This shows that TEC1-12706 is good enough to be used in low temperatures below the ambient temperature.
