Description
- FDD Low Speed Displacement Diffusers are the new air conditioning system used for comfort air conditioning in spaces with ceiling heights of 3.5 meters and above.
- In contrast to the practice in conventional systems, where air is delivered into space at certain velocities and mixed with space air
- through vents and diffusers placed on the ceiling or wall, it envisages delivering air at very low velocities and without disturbance to the space.
- Very low induction rates are used in displacement diffusers.
- Fresh air is blown into the spaces with a temperature difference of 10 to 60 K, depending on the internal heat load.
- In displacement air conditioning applications, conditioned air is delivered at very low speed through special diffusers from locations close
- to the floor levels of the neighborhood.
- It spreads over the ground due to the density it reaches, and when it approaches heat sources such as people or appliances, it rises by
- convection and thus sheds the convection generated by the heat source.
- In displacement ventilation systems, cool air that relieves convection rises as its density decreases as a result of heating.
- For this reason, the exhaust vent is placed at high levels.
- Very large halls are ideal application environments for economical air conditioning systems without creating turbulence (vortex).
