| dc.description.abstract | The Thermoelectric Refrigeration System with Peltier Effect project focuses on designing
and constructing a compact, efficient, and environmentally friendly cooling system. This
solid-state system operates using the Peltier effect, which allows heat to be transferred from
one side of a module to the other when an electric current passes through it. The main
objective is to maintain a controlled low temperature for applications such as small-scale
refrigeration, electronic cooling, and laboratory experiments.The system’s core components
include a Peltier module as the cooling element, a Switched-Mode Power Supply (SMPS)
for stable and adjustable DC power, a water cooling block as a heat sink, a pump motor for
continuous water circulation, and a temperature sensor with a display for real-time
monitoring. It was concluded that these experiments results into temperature of cold side of
Thermoelectric refrigerator to be decreased from 20.8°C to 2.3°C for 8 minute with heat
plate temperature being 25.4°C maximum and Water Temperature 25.3°C maximum 10
minute The SMPS converts the main 220 V AC supply into 12 V DC, ensuring proper
operation of all DC components. The Peltier module produces cooling on the cold side and
heating on the hot side, while the water block and pump maintain effective heat dissipation.
Real-time temperature feedback allows precise monitoring and control. This project
demonstrates the practical application of thermoelectric technology for efficient, low-power,
and silent cooling systems | en_US |
