Vav Box Hvac

What is the definition of a VAV box HVAC? A VAV box, or Variable Air Volume box, is a type of air handling unit used in heating, ventilation, and air conditioning (HVAC) systems. It is typically used to maintain a constant air temperature in a specific space, while also controlling air flow. The VAV box is equipped with dampers and thermostats that work together to automatically adjust the amount of air that is released into a space. When the thermostat detects a change in temperature, the dampers open or close to adjust the flow of air accordingly. This allows the system to maintain a more consistent temperature throughout a space. The VAV box is designed to save energy by reducing the amount of air that needs to be heated or cooled. It also reduces the noise generated by the HVAC system by decreasing the amount of air that needs to be circulated. Due to its efficiency and cost-effectiveness, the VAV box
