5. INTRODUCTION
 Air conditioning is the process of
altering the properties of air to
more favorable conditions.
 The control of these conditions
may be desirable to maintain the
health and comfort of the
occupants.

6. HISTORY
In 1902, the first modern electrical air
conditioning unit was invented by Willis
Carrier in Buffalo, New York.
The first air conditioner, designed and
built in Buffalo by Carrier, began working
on 17 July 1902.

7. TYPE OF AI CONDITIONING
1) Window air-conditioning system
2) Split air-conditioning system
3) Central air-conditioning system
4) Package air-conditioning system

8. Windows Ai conditioning System
 Window air conditioners are one of the most
commonly used and cheapest type of air
conditioners.
 Window air-conditioner units are reliable and
simple-to-install solution to keep a room cool
while avoiding the costly construction of a
central air system.

9. Split Ai Conditioning System
 The split air conditioner comprises of
two parts: the outdoor unit and the
indoor unit.
 The outdoor unit, fitted outside the
room, houses components like the
compressor, condenser and expansion
valve.

10.  The indoor unit comprises the evaporator
or cooling coil and the cooling fan

11. Central Ai Conditioning System
 The central air conditioning plants or the
systems are used when large buildings,
hotels, theaters, airports, shopping malls
etc. are to be air conditioned completely.
 The window and split air conditioners are
used for single rooms or small office spaces.
Further, these small units cannot
satisfactorily cool the large halls,
auditoriums, receptions areas etc.

12. Packaged Ai Conditioning System
 The window and split air conditioners are
usually used for the small air conditioning
capacities up to 5 tons.
 The packaged air conditioners are used for
the cooling capacities in between these
two extremes.

13. These units are used commonly in places like
restaurants, telephone exchanges, homes,
small halls, etc.

17. New Invented Technology
for Ai Conditioning System
DISTRICT
COOLING
SYSTEM
CHILLED
BEAM SYSTEM

18. District Cooling System
The Objectives :
To centralized
production of chilled
water by using district
cooling plant. The
generated chilled water
will then be channeled
to various building
blocks pre-insulated
seamless underground
pipes.

19. District Cooling System
The Advantages
1. Improve energy
efficiency
2. Protect environment
3. Save spaces
4. Improve urban view
5. Reduce manpower for
operation and
maintenance

20. CHILLED BEAM SYSTEM
 It is a type of convection HVAC system
designed to heat or cooled high rise
building such as commercial building.
 It’s primarily gives off its cooling effect
through convection by using water to
remove heat from a room.
 Pipes of water passed through the beam
suspended short distance from the ceiling
of a room

21. ADVANTAGES
 Simple to design and control
 Less mechanical space
 Less maintenance
 Increase comfort

22. Disadvantages
 Not well known in our industry
 Higher construction cost
 Many engineers aren’t familiar with this
technology

23. Applications:
Homes
Restaurants
Industry
Offices
College or University
Telephone exchanges
Auditoriums
Receptions areas

24. Conclusion
◦Air condition system makes our
life very comfortable.
We can protect hot or cold weather
by air conditioning system.
