Design and implementation of peltier based solar powered portable refrigeration unit

As the trend changes the consumption of electricity also increases, to reduce this we can use renewable sources such as solar energy which is world's most rich, stable and clean source of energy having large potential and also we see that in present refrigerator system which produce cooling effect by refrigerants like CFC's, HCFC's, Freon, ammonia which gives a maximum efficiency but the main disadvantage is that it causes the global warming ozone depletion. Now this problem can be overcome by Peltier effect and thereby protecting the environment. In this paper to introduce the portable refrigerator using peltier module with solar energy as supply which overcomes the disadvantages of existing refrigerator with increase in population and environment degradation there is an alarming rate for thermoelectric couple system have come to rescue as these are environmental friendly, affordable and compact in size.
