Abstract: Now a days, Advanced cooling solutions are needed to address the growing challenges posed by future generations of microprocessors. Many types of refrigerators are made using refrigerant which to extent affect our environment. Then it strikes to make a refrigerating system in which there is no use of refrigerant so there is an option of vapour absorption system. Now the problem occurs about its shape refrigeration system with absorption system is heavy & bulky. This leads our project to thermo-electric cooling using concept of peltier effect.Cooling and heating applications are outstanding issues, which are widely investigated in the field of thermodynamics to improve energy efficiency. Peltier devices as an element used for heating, cooling and power generation have been title of many research due to their advantages in the term of their simple structures, low weight, working with low noise and capability to manufacture in small sizes. This work was carried out with the aim of reviewing presented studies to summarize Peltier applications and their performance as an important element for refrigerators and air conditioning.
A 40 x 40 x 3.6 mm mini thermoelectric Peltier cooler was designed and built in this study. The Peltier thermoelectric cell was sandwiched between an external and internal heat sinks that acted to remove heat from the cooler box. When the Peltier thermoelectric cell connected to an external power source, the Peltier effect caused the heat from the refrigerator internal space to be conducted and removed to the ambient. This system can achieves minimum temperature of 20℃ and maximum temperature of 35 ℃ where maximum voltage occurs in about 30 minutes. For future development, this system can be used as a replacement of for conventional air-conditioner systems that use coolant that can be harmless for humans in long term.
