What is a plenum box?
Plenum boxes are usually situated on either side of the fan or heat exchanger and have the important function of bringing in, distributing, and removing air. They are the air’s first stop after being heated or cooled and its last stop before going back into your AC, heat pump, or furnace.
What does the term plenum mean?
In building construction, a plenum (pronounced PLEH-nuhm, from Latin meaning full) is a separate space provided for air circulation for heating, ventilation, and air-conditioning (sometimes referred to as HVAC) and typically provided in the space between the structural ceiling and a drop-down ceiling.
What is the purpose of a plenum box?
Plenum boxes are used to distribute heated or cooled air throughout your home’s interior. After producing heated or cooled air, the HVAC system must move that air through the ductwork. Plenum boxes take in this air so that it can be pumped into the ductwork and, therefore, distributed throughout your home’s interior.
Why is it called a plenum?
The term “plenum” was coined in the 1670s, derived from Latin adjective plenus (“filled, full”). The usage originates from classical theories of physics and the notion that “nature abhors a vacuum”.
How do plenums work?
A plenum is an air-distribution box attached directly to the supply outlet of the HVAC equipment that heats or cools the air to make the house comfortable. The ductwork that distributes the heated or cooled air to individual rooms of the house connects to the plenum.
What is open plenum?
A plenum space is a part of a building that can facilitate air circulation for heating and air conditioning systems, by providing pathways for either heated/conditioned or return airflows, usually at greater than atmospheric pressure.
Whats does BTU mean?
British thermal unit
British thermal unit/Full name
And that means what, exactly? BTU is short for British Thermal Unit, a unit of measurement that shows just how much energy your air conditioner uses to remove heat from your home within an hour.
What does the R stand for in HVAC?
Heating, ventilation, air conditioning and refrigeration (HVAC-R) technicians spend their workdays installing, maintaining and repairing various indoor climate control systems that we often take for granted.
What is the plenum box used in HVAC system/ducts?
Plenum boxes are used to distribute heated or cooled air throughout your home’s interior. After producing heated or cooled air, the HVAC system must move that air through the ductwork. Plenum boxes take in this air so that it can be pumped into the ductwork and, therefore, distributed throughout your home’s interior.
What is the plenum box in air conditioning?
A plenum in heating, ventilation, and air conditioning (HVAC) systems is a box that connects to the HVAC system . It has a critical function and that is to bring in, distribute, and remove air.
What is a plenum in a HVAC system?
A plenum is an air-distribution box attached directly to the supply outlet of the HVAC equipment that heats or cools the air to make the house comfortable. The ductwork that distributes the heated or cooled air to individual rooms of the house connects to the plenum.
What is a fan powered box?
Fan powered boxes have a fan- either series or parallel and a source of heat. Parallel boxes place the fan perpendicular drawing from plenum air and only run the fan during heating mode. Series fan powered boxes place the fan in line and run it during all occupied modes, heating or cooling.
