I'm assuming you are referring to "ducted air conditioning" (AC), a type of air conditioning system used to cool and distribute the air in a building through a network of ducts.
In a ducted AC system, a central unit (often located outside the building) cools the air and distributes it through a network of ducts and vents throughout the building. The ducts can be hidden in walls, floors, or ceilings, and the vents can be adjusted to control the airflow and temperature in different rooms or areas.
Ducted AC systems are commonly used in larger buildings, such as offices, hotels, and commercial spaces, but they can also be used in residential homes. They offer several advantages over other types of AC systems, including:
Improved air quality: Ducted systems can filter and purify the air as it circulates through the ducts, improving indoor air quality.
Zoning capabilities: Ducted systems can provide different cooling levels in different building parts, allowing for more precise temperature control and energy efficiency.
Aesthetics: Ducted systems are often preferred in commercial spaces and high-end homes because they are hidden from view, creating a more streamlined and discreet look.
However, ducted AC systems can be expensive and require regular maintenance to ensure proper airflow and efficiency. They may also be less efficient than other AC systems in smaller spaces or rooms with low ceilings, such as split systems or window units.
