Abstract

This study of the environmental challenges posed by conventional cooling systems that rely on harmful refrigerants and explores the performance of Thermo Electric Coolers (TEC) as an eco-friendly alternative. The goal of the research is to analyze the effect of varying input voltages (8V, 9V, 10V, 11V) and cooling durations (10, 15, and 20 minutes) on the cooling efficiency of the TEC1-12706 portable cooling system. The methodology involved testing the TEC module in a small enclosed cabin prototype, measuring temperature changes over time with different voltage inputs and cooling periods. The results show that higher input voltages led to greater temperature drops, with the best performance observed at 11V. Additionally, the cooling duration significantly influenced the system’s effectiveness, with the largest temperature reduction occurring in the first 10 minutes. Beyond this, the cooling effect slowed down as the system approached thermal equilibrium. In conclusion, the TEC1-12706 system, particularly at higher voltages and optimal operating times, provides a viable, environmentally friendly alternative for portable cooling applications without relying on refrigerants
