5 Aeraulic connections
The dimensioning and correct execution of the aeraulic connections are fundamental to guarantee good unit operation and adequate level
of silence in the room.
When designing and manufacturing the ducting, consider LOAD LOSSES, AIR FLOW AND SPEED that must be consistent with the unit features.
Particularly consider that load losses higher than the unit useful prevalence, lead to reduction in ow rate, with consequent unit blocks.
•
the weight of the channels must not burden on the connection anges
•
place anti-vibration joints between channels and unit
•
connection to the anges and between the various sections of the channels must guarantee air seal, avoiding dispersions penalising the
overall eciency of the system
•
limit the load losses by optimising the path, the type and number of bends and junctions
•
use wide bends evaluating the opportunity of equipping them with deectors (in particular with high air speed or bends with reduced
radius)
5.1 Treated air channelling
The internal surface of the channel must be smooth, enable its washing and must not contaminate the air.
Thermally isolate the channels and the anges to avoid energy losses and forming of condensation.
DIFFUSERS INLETS GRILLES
A correct diusion of the air in the room is determining for the level of comfort.
When choosing and positioning the grilles, inlets and diusers, avoid:
•
excessive air speed
•
forming of stagnant and stratication areas
•
cold air delivery in room
•
forming of localised currents (also due to uneven distribution of air)
•
excessive room temperature variations, vertically and horizontally
•
short circuits of the supply air towards the return air
For sound comfort, consider that:
•
the air diusers must be chosen verifying the sound power generated at nominal ow rate conditions
•
the cut-o to diusers must be carried out with exible elements
•
the return grilles must be widely dimensioned
Thermally isolate the channels and the anges to avoid energy losses and forming of condensation.
