| description | First of all, we would like to express our sincere gratitude to Almighty Allah for all the knowledge that He has given to mankind and bestowing us health and patience to complete the work.
There are a good number of people that we would like to thank in assisting us in
completion of our thesis. First, we would like to thank our supervisor, Maj Md. Faisal Kader,
PhD; not only for supporting us unconditionally, but also for his enthusiastic advice and
guidance in obtaining our degree.
We would like to extend our gratefulness to our Mechanical Engineering Department for providing financial support and specially our dean of Mechanical Engineering Department Brig. Gen. Lutfor Rahman for his efficient support and invaluable guidance.
We are grateful to Jahirul Islam and Tousif Islam for giving us ideas during construction process.
We are also grateful to Mr. Dibakor, lab instructor of ME, MIST for processing heatsink by CNC milling machine in his busy schedule.
We are also grateful to Lt Cdr KMR Sadi for his help in providing economical support. |

The increase in demand for refrigeration globally in the field of air-conditioning, food preservation, medical services, vaccine storages, and for electronic components temperature control, led to the production of more electricity and consequently more release of CO2 all over the world leads to global warming and many climatic changes. Thermoelectric refrigeration system is a new alternative because it can reduce the use of electricity to produce cooling effect and also meet today’s energy challenges. Therefore, the need for thermoelectric refrigeration in developing countries is very high where long life and low maintenance are needed. The refrigeration system of thermoelectric refrigerator (TER; 28 × 23.5 × 25 cm3) was fabricated by using a thermoelectric cooler (TEC; 4 × 4 cm2) and applied electrical power of 57.7 W. The TER has cooling fan for the coldness circulates in the refrigerator. The current, differential temperature, time, and coefficient of performance (COP) were analyzed. TEC cold plate temperature (Tc) was decreased from 30 ºC to –4.2 ºC and 55 ºC for hot plate temperature (Th). The TER temperature was decreased from 30 ºC to 19.5 ºC in 8 hrs. The maximum COP of TEC and TER were 3.0 and 0.55, respectively. 2019-03-12T03:43:39Z 2019-03-12T03:43:39Z 2017-01 Thesis http://hdl.handle.net/123456789/425 en application/pdf Department of Mechanical Engineering |
