VAV HVAC System stands for Variable Air Volume heating, ventilation and air conditioning system. This type of system is designed to provide consistent comfort and energy efficiency in a commercial or industrial space by controlling the volume and temperature of air supplied to the space. It operates by adjusting the flow rate of heated or cooled air delivered to the space through adjustable dampers, automatically modulating the speed of the fan and adjusting the supply temperature of the conditioned air according to the load in the room. This type of system is highly efficient and significantly reduces energy consumption compared to traditional systems.
