The document discusses air conditioners and their components. It introduces air conditioning as conditioning indoor air to maintain human comfort regardless of outdoor conditions. It then describes the three main parts of an air conditioner: the compressor, condenser, and evaporator. The compressor increases the pressure and temperature of the working fluid. The condenser is the outdoor unit that dissipates heat. The evaporator is the indoor unit that cools the air and contains coils and a fan.

2. INTRODUCTION
The air conditioning is that branch of engineering science
which deals with the study of conditioning of air.
(i.e.) supplying & maintaining desirable internal
atmospheric condition for human comfort, irrespective of
external condition.

3. AIR CONDITIONER
Air conditioners use chemicals that easily convert
from a gas to a liquid and back again. This chemical is
used to transfer heat from the air inside of a home to
the outside air.
 The machine has three main parts .
i. Compressor
ii. Condenser
iii.Evaporator.

5. COMPRESSOR
The working fluid arrives at the compressor as a cool, low-
pressure gas. The compressor squeezes the fluid. This packs
the molecule of the fluid closer together. The closer the
molecules are together , the higher its energy and its
temperature.

6. CONDENSER
The working fluid leaves the
compressor as a hot, high pressure gas
and flows into the condenser.
 If you looked at the air conditioner part
outside a house, look for the part that
has metal fins all around.
 The fins act just like a radiator in a car
and helps the heat go away, or dissipate,
more quickly.

7. EVAPORATOR
The evaporator is located on
the inside the house, sometimes
as part of a furnace.
That's the part that heats your
house.
This contains coil and fan .
The coil temperature is transfer
to room temperature.
