CONCLUSION (WEEK 12)

CONCLUSION

A portable mini fridge prototype was designed and built which can be used for personal cooling. Three TECs were used for achieving the cooling with a DC power supply. A conventional axial fan of 35W was used to blow the air to the cooling module. It had been shown from testing results that the portable mini fridge is capable of cooling the can. Portable mini fridge designed was able to cool an ambient air temperature from 30 °C to 22.8°C . Cooling stabilizes within one hour once the switch is turned ON. The system can attain a temperature difference of set target which was °C .Accomplishing the set target establish the success of the project. A portable mini fridge just used

battery to make it function. But it was back up by DC power supply to switch ON. Most of the items selected in the project were compromised on budget .A total of around RM600 was spend for the entire project development which includes the electrical, electronics & mechanical sections. A cost analysis segment is attached in Appendix E. All the components in the project had been tested individually and the results were found to be positive. This was the ultimate result of many a month’s hard work.
