Variable Air Volume Control System
- Piping and controls are factory installed, configured and tested
- LED display and manual controls for rapid diagnostics and service
- Variable speed technology adjusts fan speed to meet a space needs
- Low fan speeds results in quieter system
- Control algorithms reach set points faster allowing occupants to enjoy a more comfortable environment
Variable Air Volume (VAV) is a type of heating, ventilating, and/or air-conditioning (HVAC) system. The simplest VAV system incorporates one supply duct that, when in cooling mode, distributes approximately 55 °F (13 °C) supply air. Because the supply air temperature, in this simplest of VAV systems, is constant, the air flow rate must vary to meet the rising and falling heat gains or losses within the thermal zone served.
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. Buildings with diverse loading conditions can be supported by controlling the local terminal's supplemental heat. The VAV Zone Controller provides dedicated control functions for single duct, parallel fan box terminals and series fan box terminals with modulating heat, up to 2 stages of ducted heat, or combination baseboard and ducted heat.
