Types of air conditioners - Types of Residential Air Conditioning Systems

There are many types of air conditioners specifically designed
for different types of applications.Listed on the below are some of the
more common systems and their applications.

WATER-COOLED AND
AIR-COOLED SYSTEMS
The difference between a water-cooled air conditioner and an air-cooled system is in how the heat is removed from the condenser. Water-cooled systems flow water over the condenser coils to remove heat from the refrigerant inside, and air-cooled systems blow air across the condenser to remove heat.

CHILLER SYSTEMS
These systems cool by pumping a liquid over evaporator coils to provide cooling. These units are used for large buildings and to provide direct internal cooling to special types of equipment.

DUCTLESS SPLIT SYSTEM
The components of this system are separated. The condenser is located outside and is connected to single or multiple evaporator units inside. These evaporator units are connected to the condenser unit by small flexible hoses and do not use a central air duct. This system is used for residential and light commercial buildings.

PACKAGED SYSTEM
All components are packaged together in one enclosure (e.g., window unit, rooftop unit, spot cooler).
ROOFTOP SYSTEM
This is a packaged system that mounts on the roof and connects directly to central ducting. It is typically used for medium to small office buildings and commercial buildings.

WINDOW AIR CONDITIONER
This is a small packaged unit designed to fit in a window, primarily for residential use.

SPLIT SYSTEM
(Central Air Conditioning)
The components of this system are sparated in two different locations.
The evaporator is located inside and provides cooling through a central air duct. The compressor and condenser are located outside. This system is most commonly used for residential applications.

EVAPORATIVE COOLERS
These coolers do not use a refrigerant system but cool by evaporating water into the air. The units vary greatly in size and are used for anything from residential use to large industrial buildings. They work best in
dry climates
