HVAC Definitions
In this blog, we will discuss commonly used HVAC terms in building services industry:
Learning or revising definitions before working on them is always recommended.
- Understanding the terminology: HVAC design involves using many technical terms unfamiliar to beginners in the field.
- Building a foundation of knowledge: Building a foundation of knowledge to understand how all HVAC components and systems work together.
- Communicating effectively: By learning HVAC definitions, communication becomes more effective with others in the field, and misunderstandings can be avoided.
- Saving time and effort: Learning HVAC definitions saves time and effort from researching and asking for clarification, which slows down the learning process.
Here are the frequently used keywords used in the HVAC industry:
Air Balancing
This is the process of adjusting the airflow in a building to make sure that each area is getting the right amount of air.
Air Contaminants
Unwanted airborne constituents that might reduce acceptability or adequacy of the air quality.
Air Filtration
This is the process of removing particles and pollutants from the air in a building to improve indoor air quality.
Air Handling Unit (AHU)
This is a device that moves air through a building. It takes in air from outside, filters it, and then circulates it through the building.
Diversity Factor
Relates to the thermal characteristics of the building envelope, temperature swings and occupancy load.
Ductwork
Airtight devices that carry conditioned air throughout the building.
Air Leakage
Air that escapes from or to a building through a joint, coupling, junction, or the surfaces which enclose the building. The flow of uncontrolled air within a building through cracks or openings.
Air Ventilation
Share of supply air that is outdoor air, plus any recirculated air that has been filtered or otherwise treated to maintain acceptable indoor air quality.
Air Volume
Amount (volume) of air delivered to a space through ventilation, typically specified in litres per second or cubic metres per minute.
