  • Active chilled beams vs fan coil units

    August 5, 2024

    When designing HVAC systems for commercial spaces, engineers must choose between different terminal unit options like active chilled beams and fan coil units. Both technologies serve to deliver temperature-controlled air locally within a building zone. Although superficially similar, each has distinct strengths making one potentially better suited than the other based on project parameters. Active Chilled Beams Active chilled beams are linear ventilation devices mounted high on room walls or ceilings. They work by passing water through embedded cooling coils, which absorb heat from the room. Air drawn passively across these chilled surfaces via convection cools the space. Fans located internal or ...

  • AHU – Replace or refurbish?

    May 6, 2024

    Air handling units (AHUs) form the heart of a building’s heating, ventilation, and air conditioning infrastructure. Yet with continual operation over the years, critical AHU components inevitably wear down from friction, corrosion, and fatigue. Facility managers eventually face a dilemma – invest in an entire unit replacement or attempt to restore existing AHUs via strategic refurbishment. Weighing key factors helps determine the best asset and budget decision. When replacement makes sense Installing brand-new AHUs comes into play once major functional elements like blowers, heat exchangers, or control circuitry are no longer fixable and serviceable. Sometimes persisting operational disruptions or exorbitant periodic repair ...
