1.3 About the unit
1.3.1 Applications
The modular fan coil unit is designed for
heating, cooling and/or ventilating rooms.
The inlets and outlets of the unit are posi-
tioned in such a way that the discharged air
flow is distributed evenly across the room
without causing discomfort to the people in it.
The unit’s dimensions are geared to integrat-
ing the unit in suspended ceilings.
1.3.2 Working
The fan coil unit blows a flow of air into the
room. The air may be taken in, at the user’s
option, either from outside (ventilation) or
from the room itself (recirculation). Thus, the
unit offers two benefits:
- The room is kept at the desired tempera-
ture.
- Gradual deterioration of air quality in the
room is counteracted.
1.3.3 Modules
A modular fan coil unit is made up of mod-
ules. Each module has its specific function.
By combining different modules, modular fan
coil units with different features can be com-
posed.
