The document discusses air conditioners, including their history, parts, uses, and some common brands. It explains that air conditioning alters air properties to more favorable conditions and emerged in the 19th century. The key parts of an air conditioner are identified as the blower, compressor, fan, condenser coils, expansion valve, temperature sensing bulb, and cooling coils. Air conditioners are used to change the temperature and humidity within an area. Popular brands mentioned include Daikin, Toshiba, Samsung, LG, and General.
1. AIR CONDITIONER’S
Air conditioning is the process of altering the properties of air to more
favourable conditions.
More generally, air conditioning can refer to any form of
technological cooling, heating, ventilation, or disinfection that modifies the
condition of air.
Modern air conditioning emerged from advances in chemistry during the
19th century, and the first large-scale electrical air conditioning was invented
and used in 1911 by Willis Haviland Carrier. The introduction of
residential air conditioning in the 1920s helped start the great migration to
the Sunbelt.

PARTS
Conditioner Includes
a. Blower
b. Compressor
c. Fan
d. Condenser coils
e. Expansion Valve
f. Temperature sensing bulb
g. Cooling coils
3. a.blower
Blowers have the exact
same function as a fan.
Only the construction is
different. Fans are
normally used at
condensing units, while
blowers are used for
evaporation units.
4. b.Compressor
In simple terms, an A/C
Compressor is a pump. The
compressor is the 'heart' of the
air conditioning system, moving
refrigerant through the system.
While many people believe the
compressor puts out
cold air, that is incorrect; it
actually creates heat. The
compressor puts the air
conditioning refrigerant
under extremely high pressure.
5. c.FAN
The fan consists of a
rotating arrangement of
vanes or blades which act
on the air. Most fans
are powered
by electric motors. Fans
produce air flows with
high volume and low
pressure.
6. d.Condeser Coils
A condenser coil is one
of many types of heat
exchangers. The primary
purpose of a heat
exchanger is to efficiently
transfer heat between two
mediums. Condenser coil
s are found in space
heaters, air
conditioners, and car
radiators.
7. e.Expansion Valve
A thermal expansion
valve is a component
in refrigeration and air
conditioning systems that
controls the amount of
refrigerant flow into the
evaporator thereby
controlling
the superheating at the
outlet of the evaporator.
9. g.Cooling Coils
An evaporator is a
device used to cool air.
It is part of a
cooling system found
in
freezers, refrigerators
and air conditioners.
Evaporators are
responsible for the cool
air that comes out of
the vents. The
evaporator's cooling
mechanism uses heat
to do the job.
10. Use Of Air Conditioner
• An air conditioner is a major or home appliance, system,
or mechanism designed to change the air temperature and
humidity within an area.
