Thanks to the new automatic speed control in relation to the pressure drops of the system, the centrifugal fans, which are directly
coupled to a DC motor, ensure a constant air ow rate.
The benets deriving from this design solution are featured along the three development and management stages of the system, indeed:
▶
It simplies the design of the air distribution system, as it is not necessary to take into account extremely small tolerances when
calculating the pressure drops of the system itself.
▶
It makes it easier to install and activate the unit in the event of system congurations carried out during installation that dier from
the ones reported on the project.
▶
In the event of soiled lters or incorrect cleaning of the system, it prevents the machine from going in stand-by or from less than
optimal operation due to a drop in the ow rate.
A. Air intake lter
It puries external renewal air before it is introduced in rooms
with a standard lter (G3). It can be tted with an optional high
eciency electrostatic lter (H10).
B. “Standard” exhaust air lter
These units with reduced power are tted with the internal G2
lter as standard.
C. Supply fan
The new control allows to maintain a constant rotation speed as
the system’s pressure drops vary, with 60% less power absorbed
compared to traditional fans.
D. Compressor
R134a airtight rotary compressor chosen to optimise the reduced
power unit with higher performance levels.
E. Exhaust fan
The new control allows to maintain a constant rotation speed as
the system’s pressure drops vary, with 60% less power absorbed.
F. Electrical panel
Easy to access in order to conduct maintenance and take it out
through the openings.
G. White prepainted aluminium unit
H. DN150 air ducts
Air distribution system size designed in relation to the unit size.
I. Internal exchanger
Finned direct expansion exchanger with copper tubes and
aluminium ns
Reduced pressure drops compared to passive recovery units.
L. External exchanger
Finned direct expansion exchanger with copper tubes and
aluminium ns
Reduced pressure drops compared to passive recovery units.
