Videocon is an Indian conglomerate that manufactures refrigerators and other appliances. The document describes Videocon's refrigerator manufacturing process, which includes pressing and forming sheet metal, painting parts, pre-assembling components, and final assembly. It explains the main parts of a refrigerator like the compressor, condenser, freezer box, and how refrigeration works by compressing and condensing a refrigerant. The production flow takes raw materials through various shops like pressing, painting, vacuum forming before final assembly and testing of the refrigerators.

3. Introduction to Videocon
 Videocon is an industrial conglomerate with interests
all over the world.
 The company was incorporated as a public limited
company in August 1989 and was originally
promoted by Maharaja International Ltd. to produce
washing machine, refrigerator, and dishwasher.

4.  In India the group sells consumer products like Colour
Televisions, Washing Machines, Air
Conditioners, Refrigerators, Microwave ovens and many other
home applications. Videocon Group brands include
Sansui,Toshiba,Electrolux ,Ken star Godreg
,Samsung,Whirlpool,LG etc.
 Videocon is one of the largest CPT Glass manufacturers in the
world, operating in Mexico, Italy, Poland and China.

5. Shops in Plant
 Press shop
 Paint shop
 Vacuum forming shop
 Pre-Assembly shop
 Final Assembly shop

6. Press shop:forming press, commonly shortened to press, is
a machine tool that changes the shape of a work
piece by the application of pressure.

7. Paint shop:To paint the side, back and door panel.
Vacuum forming shop:In this section, the main cabinet and door
liners are formed.

8. Pre-Assembly shop:pre assembly means to mount components onto a
plate means they are ready to install on the machine.
Final Assembly:In this we assemble all parts of refrigerator after the
verification of each and every part.

10. Parts of fridge
 INVERTER: Inverter is a frequency drive used to invert the A.C.
to D.C.
 The drive converts the phase from single phase to
three phase if the power supplied is in single phase

11. Compressor
 The compressor is the heart of the refrigeration system
 compressor it is then compressed depending on what
type of compressor it is from a cold low presure
refrigerant into a high presure hot refrigerant.
 The compressor not only keeps the refrigerant moving
throughout the hole system it also creates a pressure
change.

12. Condenser
 It is a heat-exchange device in a refrigeration system
 It is a Device for reducing a gas or vapour to a liquid
Heat Exchanger
 A heat exchanger is a piece of equipment built for efficient heat
transfer from one medium to another.
 They are widely used in space heating, refrigeration, air conditioning, power
plants, chemical plants,petrochemical plants, petroleum refineries, natural
gas processing, and sewage treatment

13. FREEZER BOX
 These are made from Aluminium Roll bonded, which
undergoes the following operation: Notching & Punching
Hammering.
Butt-welding of inlet & outlet tubes to the
freezer box, further the hole Is cleared
by drilling

14. How Does a Refrigerator Work?
 1.The compressor constricts the refrigerant vapor, raising its
pressure, and pushes it into the coils on the outside of the
refrigerator.
2. When the hot gas in the coils meets the cooler air temperature of
the kitchen, it becomes a liquid.
3. Now in liquid form at high pressure, the refrigerant cools down as
it flows into the coils inside the freezer and the fridge.
4. The refrigerant absorbs the heat inside the fridge, cooling down
the air.
5. Last, the refrigerant evaporates to a gas, then flows back to the
compressor, where the cycle starts all over.

16. MAIN ASSEMBLY
