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.
