What are VAV units?
A VAV — i.e., Variable Air Volume — HVAC (heating, ventilation, and air conditioning) system that supplies air at varying levels or amounts at a constant temperature. These comprise of multiple VAV terminal units or boxes that diffuse air in specific areas of a large indoor space, such as an auditorium.
What is K factor VAV?
The K factor is the point at which the size of the box, shown in inches, converges with the maximum airflow at 1″w.g. velocity pressure (on the far right). See examples below. Based on the graph, we can see that the maximum airflow for a 6″ VAV box is 515CFM.
What is VAV function?
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.
What is VAV controller?
Variable Air Volume Control System Variable Air Volume (VAV) is a type of heating, ventilating, and/or air-conditioning (HVAC) system. The VAV Zone Controller has a built-in actuator and maintains zone temperature by operating the terminal fan and regulating the flow of conditioned air into the space.
What is the difference between VAV and CAV?
HVAC engineers can choose between CAV and VAV systems depending on the application. While a CAV system uses variable air temperature and constant airflow, a VAV system keeps constant temperature and variable airflow.
What is HVAC unit CSU?
Ceiling Suspended AHU (CSU)
Why choose a Barcol-air induction VAV terminal?

Why choose Barcol-air?
From its origins in Europe, 1934, the Barcol-Air brand has grown in reputation with worldwide operations specializing in commercial air conditioning, the indoor environment and expertise in low energy air conditioning systems.
What is an induction VAV system?
However the Induction VAV system takes the energy saving capability and comfort levels of the system to a higher level. These benefits are achieved through the use of special induction VAV terminals that induce room air into the terminal to mix with the primary air before the total air is delivered to the air conditioned space.
What is a vav or CAV unit?
The VAV or CAV units can be used either for supply or return air applications in new or refurbishment projects. The units do have a single wall (NK) or double wall (NL) construction and can optionally be supplied with an additional sound attenuator and a plenum with built-in electric reheat coil. Features:
