CONTENTS TO BE DISCUSSED  Introduction  Working  Advantages

 Disadvantages  Applications  Work up till now  Work to be done  Conclusion  References

INTRODUCTION  What is refrigeration?  Why thermoelectric refrigeration?

WORKING  Components  Thermoelectric module  Refrigeration chamber  Air circulation system  Temperature measurement system  Principle of working

FIG. THREMOELECTRIC MODULE

ADVANTAGES  No use of CFC’s or HCFC’s  Less moving parts, no lubrication required  No wear, friction, noise or vibration

 Compact size  Light weight  Lower price

DISADVANTAGES  Low coefficient of performance  Not suitable for mass storage

APPLICATIONS  Wine stores  Cooling of aircraft cock-pit  Cooling of electronics devices

 Medicine stores

WORK UP TILL NOW  Research papers have been studied  Some video clips about fabrication  Supplier of components is found out

 Some patents are studied

WORK TO BE DONE  Buying thermoelectric module  Fabrication process  Thermal analysis

 Some more research papers on fabrication

CONCLUSION  Thermoelectric refrigerators are cheaper as compared

to conventional one.  Due to the lower price, compact size and low battery required, thermoelectric refrigerators will be having great future.  No use of CFC’s i.e. eco-friendly.
