6. 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.

7. 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.

8. TYPE OF AIR-CONDITIONING Window air-conditioning system Split air-conditioning system Central air-conditioning system Package air-conditioning system

9. 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.

10. 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 .

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

12. Central Air-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.

13. 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 .

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

18. New Invented Technology for Air-Conditioning System DISTRICT COOLING SYSTEM CHILLED BEAM SYSTEM

19. 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.

20. District Cooling System The Advantages Improve energy efficiency Protect environment Save spaces Improve urban view Reduce manpower for operation and maintenance

21. 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

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

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

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

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