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

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.

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.

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.

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

DISTRICT COOLING SYSTEM

CHILLED BEAM SYSTEM

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.

District Cooling SystemThe Advantages1. Improve energy

efficiency2. Protect environment3. Save spaces4. Improve urban view5. Reduce manpower for

operation and maintenance

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

ADVANTAGESSimple to design and controlLess mechanical spaceLess maintenanceIncrease comfort

Disadvantages

Not well known in our industry

Higher construction cost

Many engineers aren’t familiar with this technology

Applications: Homes

Restaurants Industry Offices College or University Telephone exchanges Auditoriums Receptions areas

Conclusion◦Air condition system makes our life very comfortable.

We can protect hot or cold weather by air conditioning system.
