7 - AERAULIC CONNECTIONS
7.1 AERAULIC DESIGN CRITERIA
If the duct outlets for the outdoor air inlet and exhaust are
outside of coverage, must end with a 90 ° bend downward, to
prevent entry of water from the air inlet.
To perform the ductings:
 Connect the ductings fixing them to the connections with
the special hookings to the circular flanges.
 The duct weight should not lie on the connection flanges.
 Put antivibration joints between ducts and units.
 The connection to the flanges and among the different
duct sections must guarantee the air seal, avoiding air
dispersions in supply and return that penalize the overall
efficiency of the installation.
 Limit the pressure drops by optimizing the path, the type
and the number of curves and branches.
 Use curves of large radius.
 For unit air outlet with duct, when unit operating,
condensate will be generated aroud outside of duct.
 Thermically insulate the supply ducts to avoid heat losses
and condensate.
7.2 AIR DUCT CONNECTION
The dimensioning and the correct execution of the aeraulic
connections are critical to ensure the unit operating and an
appropriate level of quietness in the served area.
Pressure loss in the duct will reduce the air flow, which can
cause a reduction in efficiency of the unit.
The maximum static pressure should be within 25Pa
7.3 DIMENSION CONNECTIONS
Avoid recirculation of exhaust/return air
Use elbows with a 90° downward bend
Minimum exhaust distance (M) / return distance (R)
Exhaust / return grille (Provided by the customer)
External air return
 positioned in an area with a low concentration of impuri-
ties (dust, odours, exhaust fumes, etc.).
Exhaust outlet
 away from terraces, balconies, property boundary lines;
 avoid windward zones
