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
