Energy efficient displacement systems

Energy-efficient displacement air handling systems provide a superior solution for maintaining indoor air quality and temperature control by introducing air at low velocity directly into the occupied zone. Utilising natural buoyancy, these systems effectively remove heat and airborne contaminants, ensuring a healthier environment, reduced energy consumption, and lower lifecycle costs.

Multiple Benefits we offer:

  • Energy efficient – less air required to condition occupied zone
  • Full fresh air delivered to where it’s required
  • 50% more heat removed per M³ compared to conventional mixing systems
  • 5 times more effective at removing internal airborne contamination
  • Much lower lifecycle costs
  • Existing mixing systems can be relatively easily upgraded.

    Displacement – How does it work?

     

    1. By using the natural buoyance of air as it absorbs heat from process, products and people.
    2. Displacement air distribution introduces air into your occupied working zone at low velocity.
    3. Natural buoyance forces ensure that the fresh cool air pools at low level.
    4. As this air comes into contact with heat sources – your people and machinery – it forms a thermal plume that takes the warm internal air and many of the airborne contaminants upwards where it can be extracted.
    5. It can be directed either to the outside or in air-conditioned environments, correctly filtered to remove any virus or contamination that might be present, before being chilled and reintroduced into the area.

    Displacement – why do we need it?

     

    • To protect product and process
    • Positive pressure to prevent ingress of contamination
    • Maintain the low temp chill chain to protect product
    • Maintain product conditions i.e. moisture levels
    • Remove internal contamination
    • Protect personnel and building fabric
    • Provide acceptable working conditions
    • Remove corrosive elements steam etc to protect fabric
    • Prevent condensation and cross contamination risks

     

    Still Using Standard Mixing Systems to control indoor air quality?

    Typically, air handling systems, whether designed for ventilation or air conditioning, rely on mixing clean supply air with the existing internal air. This process creates a mixed average condition that incorporates all the potential contaminants from the internal air. Consequently, any airborne viruses, bacteria, or other pollutants are circulated throughout the space, increasing the likelihood of exposure and infection among employees. This continuous blending and recirculation of contaminated air can severely undermine indoor air quality, making it difficult to ensure a safe, healthy, and comfortable working environment. Additionally, this approach can exacerbate the spread of airborne illnesses, posing a significant risk to employee health and productivity.
