Minimum average water temperature
If the fan coil is working in continuous
cooling mode in an environment where
the relative humidity is high, condensate
might form on the air delivery and
on the outside of the device. This
condensate might be deposited on any
objects underneath and on the floor.
To avoid condensate on the external struc-
ture of the apparatus with the fan in
operation, the average temperature of
the water must not be lower than the lim-
its shown in the table below, that depend
on the thermo-hygrometric condition of
the air in the environment.
The limits mentioned above refer to opera-
tion while the fan is set
to its minimum speed level.
TECHNICAL DATA AND OPERATING LIMITS
Performance values refer to the following conditions:
- at the maximum motor speed;
- the total input power is determined by adding the input power
for the unit to the input power for the accessories connected and
declared in the corresponding manuals.
Water temperature
In order to prevent air stratification in the
room, and therefore to achieve improved
mixing, it is advisable not to supply the fan coil
with water at a temperature over 65°C.
The use of water at high temperatures
could cause squeaking due to the different
thermal expansions of the elements (plastics
and metals), this does not however cause
damage to the unit if the maximum operating
temperature is not exceeded.
MACHINE PURPOSE
The fan coil is a room air treatment terminal unit for both winter and summer operation.
FCLI VERSION
Cassette-type fan coil with Inverter for installation in suspended ceilings; can be integrated in standard 600x600 and
840x840 panelling.
