Variable air volume (VAV) is a type of heating, ventilating, and/or air-conditioning (HVAC) system.
VAV systems supply air at a variable temperature and airflow rate from an air handling unit (AHU). Because VAV systems can meet varying heating and cooling needs of different building zones, these systems are found in many commercial buildings.
A VAV system reduces energy costs and minimizes carbon footprint. Quality and performance set our variable air volume boxes apart from others in HVAC.
VAV (variable air volume) is an HVAC system that adjusts airflow to different zones based on real-time heating or cooling demand, improving energy efficiency and comfort compared to traditional constant airflow systems.
Variable air volume (VAV) system in HVAC system is described along with basics, definition, how does a VAV system work, features,
What is a Variable Air Volume (VAV) System in HVAC? Working ...
The VAV air conditioning system, or Variable Air Volume system, is a cornerstone of modern commercial HVAC design. It modulates the amount of conditioned air delivered to different zones, improving comfort and energy efficiency. This article explains how VAV systems work, their benefits, design considerations, and maintenance practices, with practical guidance for engineers, facility managers ...
How It Works: Has small fans in VAV boxes that recirculate room air, providing additional heating/cooling. Pros: Maintains airflow even when AHU slows down, better heating efficiency.
