Airflow and temperature regulation

Airflow and temperature are the core in the operation of an Air Handling Unit.​ Swegon GOLD units have all functionality to achieve a perfect indoor environment and optimise the energy consumption.

Airflow regulation

There are several ways to control the airflow in a building, from constant air volume to a more demand-oriented regulation.

  • Constant air volume
    The speed of the fans is automatically regulated to provide required airflow, even when the filters or the air diffusers become clogged. Choose set points for low speed and high speed, in l/s, m³/s, m³/h or cfm.
  • Variable air volume
    Room sensors control damper operations which increase or decrease the air volume in parts of the ventilation system. This allows zoning in the building and makes the system more energy efficient.
  • Demand controlled air volume
    Adding air quality sensors, measuring CO2 or VOC, you can control airflow and temperature in an even more exact and dynamic way.

Airflow regulation functions

  • Density-corrected airflow​ (patented function)
    As air density differs at different temperature, this function makes sure that the defined airflow is obtained at any time.
  • Setpoint displacement​ (e.g. assembly halls)
    This is a function for areas where presence varies.
    An external signal, e.g. from a potentiometer, regulates the airflow between a higher and a lower flow. The IQlogic+ module accessory is required.
  • Pressure balance corrected extract airflow, rotary heat exchanger​ (minskar luktöverföring)
  • Outdoor air compensation 
    Adapts the airflow at specific outdoor air temperatures ​
  • Air adjustment​ (vid injustering; setup)
  • Booster diffusers​
    The diffusor pattern is adjusted depending on whether the supply air is warmer or cooler than the room air/extract air. Special diffusors and IQlogic+ module are required.
  • Optimize with WISE room management system
