Ventilation & Fresh Air System is a bigger version of the window air conditioner. However, unlike window air conditioner or Package units, it has a higher cooling or heating capacity and is usually able to cool an entire house or a commercial building. Carrier AC Dealers in Bangalore
Central air conditioners circulate cool air through a system of supply and return ducts. Supply ducts and registers (i.e., openings in the walls, floors, or ceilings covered by grills) carry cooled air from the air conditioner to the home. This cooled air becomes warmer as it circulates through the home; then it flows back to the central air conditioner through return ducts and registers.
