Displacement Ventilation Providing Cold Air Supply

Displacement Ventilation Providing Cold Air Supply

FabricAir provides several ventilation strategies to help create a more comfortable environment. Some of these flow models are designed to produce low-throw, which is perfect for displacement ventilation applications.

A typical displacement ventilation example is an underfloor air conditioning system, often used in Server Rooms and in Energy efficient office buildings. FabricAir ducts are ideal in this application and have the advantage of reducing thermal degradation, due to heat from the floor below, and a more even pressure distribution in the underfloor plenum.

Compared to the air ventilation strategies used by metal ducts and other traditional HVAC systems, displacement ventilation with fabric ducts provides two main benefits:

  • Improves air quality. Displacement ventilation provides better air quality and a better working environment by introducing conditioned fresh air directly into the occupied zone and then removing contaminated air through a combination of convective forces and exhaust/return air.
  • Energy savings. Displacement ventilation does not require high velocity air, which reduces fan energy consumption. More importantly, introducing the air directly into the occupied zone eliminates the unnecessary air mixing that happens with overhead systems. This allows for the supply air temperature to be higher, thereby reducing the size of the AC compressor allowing for reduced energy consumption. Displacement ventilation is a good approach for an energy-efficient HVAC system.

Fabric ducts operating with displacement ventilation provide the occupied area with excellent indoor air quality at a reduced expense. Displacement ventilation is the ideal air conditioning approach for buildings that are trying to achieve energy savings and second to none indoor air quality.
