Installation: While the duct is being installed, you need to aware of the following installation parts:
Plenum, is an air distribution appliance that is located near the fan or heat exchanger. It is responsible for circulating the conditioned air after it has been heated or cooled to the rooms. A duct responsible for carrying the air is connected directly to the plenum.
Supply Air Plenum: The supply air duct is used to transfer the heated or cooled to the building air after it has been conditioned by the HVAC system. After being conditioned to the desired temperature and humidity it then travels to the Air handling unit and from there it reaches the return air plenum through the duct system.
Return Air Plenum: The HVAC system supplies air to the rooms as well as pulls it out. If the air is not pulled out then a pressure will be created inside the room by bringing heat , humidity and contaminants causing an uncomfortable indoor environment. Return ducts are installed to supply the indoor air outdoors through outlets called Grilles
Location: The right location of the duct system plays a major role in the air flow and working of the duct and other parts. Ductwork is generally located in the attic, the basement or ceilings and should be installed within a conditioned space of the building.
