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.

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.

TYPE OF AIR-CONDITIONING1) Window air-conditioning system2) Split air-conditioning system3) Central air-conditioning system4) Package air-conditioning system
![Page 9: Air conditioning-system ppt](https://reader036.fdocuments.in/reader036/viewer/2022062310/5870fc951a28ab5f528b5e3b/html5/thumbnails/9.jpg)
Windows Air-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.

Split Air-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.
![Page 11: Air conditioning-system ppt](https://reader036.fdocuments.in/reader036/viewer/2022062310/5870fc951a28ab5f528b5e3b/html5/thumbnails/11.jpg)
The indoor unit comprises the evaporator or cooling coil and the cooling fan

Central Air-Conditioning SystemThe 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.
![Page 13: Air conditioning-system ppt](https://reader036.fdocuments.in/reader036/viewer/2022062310/5870fc951a28ab5f528b5e3b/html5/thumbnails/13.jpg)
Packaged Air-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.
![Page 14: Air conditioning-system ppt](https://reader036.fdocuments.in/reader036/viewer/2022062310/5870fc951a28ab5f528b5e3b/html5/thumbnails/14.jpg)
These units are used commonly in places like restaurants, telephone exchanges, homes, small halls, etc.

New Invented Technology
for Air-Conditioning System
DISTRICT COOLING SYSTEM
CHILLED BEAM SYSTEM
![Page 19: Air conditioning-system ppt](https://reader036.fdocuments.in/reader036/viewer/2022062310/5870fc951a28ab5f528b5e3b/html5/thumbnails/19.jpg)
District Cooling SystemThe 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.
![Page 20: Air conditioning-system ppt](https://reader036.fdocuments.in/reader036/viewer/2022062310/5870fc951a28ab5f528b5e3b/html5/thumbnails/20.jpg)
District Cooling SystemThe Advantages1. Improve energy
efficiency2. Protect environment3. Save spaces4. Improve urban view5. Reduce manpower for
operation and maintenance
![Page 21: Air conditioning-system ppt](https://reader036.fdocuments.in/reader036/viewer/2022062310/5870fc951a28ab5f528b5e3b/html5/thumbnails/21.jpg)
CHILLED BEAM SYSTEMIt 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
