Plenum
A plenum is the ducting both prior to and after the furnace or /AC coil if the system has AC as well. It is often sheet metal, however today they may be made from duct board a light weight, insulated product.
Plenum rated cabling is required when used in an open ceiling return air environment. That is when the return air for the hvac units use the space between the ceiling of the first floor and the floor of the second floor as a return air plenum. The way to tell is if the return air vent has a duct attached to it. The duct will run to the air conditioning air handler. This condition IS NOT a plenum rated ceiling. However, if the return air vent does not have a duct, that means the air conditioning air handler is using the air space between floors as a plenum. This condition requires the use of plenum rated cabling. If plenum rated cable is exposed to flame, it does not give off toxic gases as it melts.
Induction Unit
"Plenum" typically refers to a fully air-filled space within a building where air circulates for heating, ventilation, or air conditioning purposes. It can also refer to a space in a structure that is completely filled with gas. it is often used in HVAC systems to refer to the main air distribution chamber.
It is in the middle underneath. You must remove the center console to gain access. Then remove all the trim under the dash. It is a white unit located on the bottom of the hvac plenum.
Starter is located underneath plenum.
Water in the HVAC drip pan usually indicates blockage in the condensate drain line and or inside the plenum. Remove the condensate drain line where it attaches to the unit and check for blockages. If no blockages are found in the line or no water drains from the plenum, then open up the access panel to expose the A-coil. Clean out any debris or blockages as needed. Pour Clorox down the condensate drain line and make sure that the line is sloping to the exterior. It may be necessary to blow the line out. Check the discharge side of the drain line to be sure water is flowing. Note: It is recommended to have a licensed HVAC technician service the system to be sure that it is functioning properly.
The plenum is the intake manifold.
it is coated in a fire-reatrdant cladding and it is installed in the air-handling space used by air conditioning systemms
It means that it does not have an air conditioner or furnace installed. HVAC stands for "heating, ventilating, and cooling". HVAC is an integrated system that is not free standing, like a window air conditioner or heater.
