3.5 Air channelling
When designing and manufacturing the ducting, consider LOAD LOSSES, AIR FLOW AND SPEED that must be consistent with the unit features.
Limit the load losses by optimising the path, the type and number of bends and junctions.
Consider that excessive external static pressure will lead to a reduction in ow rate, with consequent alarm lockout.
Ensure ducts are thermally insulated.
The weight of the ducting must not burden 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 eciency of the system.
Vertical outlet standard (1)
Rear outlet option (2)
Provide:
•
water discharge (3-A)
•
grilles to restrict access to small animals (3-B)
•
deectors (3-C) to avoid the by-pass between the two air ows
•
safety grille (4-D)
Avoid therefore:
•
angle curves and narrowings (5)
•
direct air ow on people (6-7), windows, doors, plants, obstacles in general
•
obstacles that prevents the air inow to the coil (8-9)
•
installations next to silent rooms
