This project presentation summarizes a renewable energy-based refrigeration system. The system uses a Peltier chip to produce a refrigeration effect when powered by a battery. The battery is charged using solar panels, a windmill, and a hand wheel that converts rotational energy to electrical energy. Heat is removed from one side of the Peltier chip using a heat sink. The system provides low-cost, portable refrigeration without vibrations or noise for applications such as food preservation, medical supplies, and more.

4. introduction
 In the present scenario power becomes major need for
human life.
 So we are used renewable energy resource in refrigeration
system
The refrigeration is Achieved by the Peltier effect
The peltier effect is just opposite to the Seebeck effect.
In seebeck effect, in which two dissimilar electrical conductors
or semi conductor produce a voltage difference between two
substances.

5.  It is the removal of heat from a space at a temperature lower
than the surrounding temperature .
In Other word refrigeration is the science of providing &
maintaining temperature below that of surrounding atmosphere.
Refrigeration is a process in which work is done to move heat
from one location to another.
WHAT IS REFRIGERATION ...?

6. Method of Refrigeration
 Cyclic Refrigeration
1. VCRS
2. VARS
 Non –Cyclic
1. Refrigeration by Peltier Chip with using
Renewable or non-renewable energy source.

7.  This effect was first discovered in 1834 by the french
physicist Jean-Charles-Athanase Peltier
An effect, whereby heat is given out or absorbed when an
electric current passes across a junction between two
material.
In other word, The cooling of one junction and the
heating of the other when electric current is maintained.
The Whole circuit are called Peltier chip.
Peltier effect

8. The chip, which is produce a Peltier effect.
It is made by two unique semi-conductors, one n-type & one p-
type.
They have different density of electrons
 The semi-conductors are placed thermally in parallel to each
other & electrically in series and then joined with a thermally
conducting plate on each side.
Peltier chip Design

10.  Operate by the Peltier effect.
When a voltage is applied to the free ends of the two
semi-conductors.
 there is the flow of DC current across the junction of
the semi-conductors causing a temperature
difference.
 it brings heat from one
side & other is cooler.

13. Renewable energy
 The energy which is collected from renewable resources,
which are naturally resources. such as sunlight, wind, rain ,
tides, waves, and geothermal heat.
It is often provides energy in four areas;
1. Electricity generation
2. Air & water heating /cooling
3. Transportation
4. Rural (off-grid)

14. UsedRenewable resources
 We are using 3-type of renewable resources ;
1. Solar panel
2. Wind mill
3. Hand wheel

15.  Photovoltaic solar panels absorb sunlight as a source of energy to
generate electricity
 Photovoltaic modules constitute the photovoltaic array of a photovoltaic
system that generates and supplies solar electricity.
 The majority of modules use wafer-based crystalline silicon cells or thin-
film cells.
Solar panel

16. Wind mill
 A windmill is a structure that converts the energy of
windmill into rotational energy by means of vanes
called sails or blades.
 There are windmills that convert the rotational energy
directly into heat.

 NACA-44
 Ply wood profile
 Air breezer profile
 New blade profile
types of blade

18.  Any Wheel worked by hand, that move in a hand rotating
direction produce a mechanical energy
 The mechanical energy which again convert into the
electrical energy by the help of dynamic generator.
Hand wheel
