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.

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.

Shops in Plant

Press shop

Paint shop

Vacuum forming shop

Pre-Assembly shop

Final Assembly shop

 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.

Paint shop:-

To paint the side, back and door

panel.

Vacuum forming shop:-

In this section, the main cabinet and

door liners are formed.

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.

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

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.

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

FREEZER BOXThese 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

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.

Conclusion helped me to understand the practical

applications of manufacturing of refrigerator

and helped me to study on various machines

involved in manufacturing.
