VAV Box HVAC stands for “Variable Air Volume Box Heating, Ventilation, and Air Conditioning”. It is an important part of any HVAC system, as it helps balance air pressure and temperature within a building. VAV box HVACHVAC systems consist of three main components: A motorized air damper that modulates the volume of air entering the space; a heating or cooling coil, which heats and cools the air; and a fan that moves the air through the system. By controlling both the volume of air entering the space and its temperature, VAV Box HVACHVAC systems are capable of providing precise climate control with minimal energy waste.
