UNDERDRAFT Meaning and
Definition
-
Underdraft is a term that is mainly used in the context of natural or artificial ventilation systems. It refers to a condition in which the flow of air in a specific area or space is insufficient or inadequate to meet the desired or necessary ventilation requirements. An underdraft occurs when there is an insufficient supply of fresh air or when the movement of air is hindered, leading to poor air quality or reduced air circulation.
In natural ventilation systems, underdraft commonly occurs due to unfavorable external conditions such as low wind speeds, obstruction of air passages, or inadequate ventilation openings. This can lead to a build-up of pollutants, humidity, or unpleasant odors within a space, which can have adverse effects on occupants' health, comfort, and productivity.
In artificial ventilation systems, underdraft can result from the improper design, sizing, or operation of ventilation equipment, such as fans or air handling units. It can also occur when there are blockages in air ducts or when the system is not adequately maintained. Underdraft in artificial ventilation systems may compromise air quality, reduce the efficiency of the ventilation system, and result in energy wastage.
To rectify an underdraft, it is essential to identify the underlying cause and take appropriate measures. This may involve adjusting the ventilation system settings, removing obstructions, ensuring sufficient air intake, or modifying the ventilation system design. Proper maintenance and regular monitoring of ventilation systems are crucial to prevent underdrafts and ensure optimal air quality and circulation in indoor environments.

Etymology of UNDERDRAFT
The word "underdraft" consists of two parts: "under" and "draft".
The term "under" is derived from Old English "under" or "und" which means "beneath" or "below". It has been used in English since the 9th century to indicate a position lower or lesser than something else.
The word "draft" comes from the Old English "draught" or "dræg", meaning a drawing, pulling, or something dragged. From there, it evolved to refer to the act of pulling or dragging something, or a flow of air, water, or liquid. In this case, "draft" refers to a flow of air.
Combining these two words, "underdraft" refers to a flow of air that is under or beneath something else.
