An unlouvered wall register, which allows circulation of air from one floor to another. Registers vary in size with the heating and cooling requirements of the room. [5] If a register is too small, the HVAC system will need to push air through the ducts at a faster rate in order to achieve the desired heating or cooling.
Vertical section through a commercial building using HVAC plenum instead of airspace plenum. When both the supply and return ducts are constructed in this manner, it is possible to insulate the ducts and the dropped ceiling so that the upper airspace is not heated or cooled, increasing energy efficiency. This is a fully enclosed plenum.
The return plenum carries the air from several large return grills (vents) to a central air handler for re-heating. The supply plenum directs air from the central unit to the rooms which the system is designed to heat. Regardless of type, all air handlers consist of an air filter, blower, heat exchanger/element/coil, and various controls.
The percentage of return air made up of fresh air can usually be manipulated by adjusting the opening of this vent. Typical fresh air intake is about 10% of the total supply air. [citation needed] Air conditioning and refrigeration are provided through the removal of heat. Heat can be removed through radiation, convection, or conduction.
The needed airflows include, for example, supply air, return air, and exhaust air. [1] Ducts commonly also deliver ventilation air as part of the supply air. As such, air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort. A duct system is also called ductwork.
DV systems deliver cool air into the conditioned space at or near the floor level and return air at the ceiling level. This works by utilizing the natural buoyancy of warm air and the thermal plumes generated by heat sources as cooler air is delivered from lower elevations. While similar, UFAD tends to encourage more mixing within the occupied ...

The furnace, built on the outside of the workshop, featured earthen pipe-like air vents with hundreds of tiny holes in them and a prototype chimney to ensure air goes into the furnace to feed the fire and smoke comes out safely. [39] Passive ventilation and passive cooling systems were widely written about around the Mediterranean by Classical ...
