Function
FSL-B-ZAB
Functional description
Decentralised supply air and extract air units for
room ventilation and extract ventilation and for
dissipating cooling loads and heat loads.
An EC centrifugal fan takes in the fresh air which
then flows through the motorised shut-off damper,
the volume flow controller and the F7 filter.
Once the fresh air has passed the fan, it flows
through the recuperative heat exchanger for heat
recovery; it is possible to bypass the recuperative
heat exchanger in order to protect it, or when it is
sensible with regard to energy efficiency.
If necessary, the air is heated or cooled by the
heat exchanger before it is discharged to the room
as a displacement flow.
The extract air first passes a G3 filter, then flows
through the heat exchanger (for heat recovery),
the extract air fan and the motorised shut-off
damper before it is discharged to the outside as
exhaust air.

Decentralised ventilation
Basic information and nomenclature
Types of ventilation
Mixed flow
The supply air is discharged from the diffuser into
the space with a velocity between 2 and 5 m/s.
The resulting air jet mixes with the room air,
ventilating the entire space. Mixed flow systems
typically provide a uniform temperature
distribution and air quality within the space. The
originally high velocity of the turbulent air jet
decreases rapidly due to the high induction levels
of mixed flow systems.

Displacement flow
Die Zuluft strömt möglichst bodennah mit velocity
between 0.15 and 0.20 m/s and as close as
possible to the floor; the result is a pool of fresh air
over the entire floor area. The convection from
people and other heat sources causes the fresh
air from the pool to rise and create comfortable
conditions in the occupied zone. Displacement
flow ventilation is characterised by low airflow
velocities and low turbulence. The air quality in the
occupied zone is very high. The extract air should
ideally be removed near the ceiling.

Inducing displacement flow
The supply air is discharged near the external wall
and with a medium velocity between
1.0 and 1.5 m/s. Due to the induction effect the
supply air velocity is rapidly reduced such that, in
cooling mode, the supply air displaces the room
air over the entire floor area. The convection from
people and other heat sources causes the fresh
air from the pool to rise and create comfortable
conditions in the occupied zone.

Heat exchanger
Heat exchanger
The water flow temperature (cooling circuit)
should be at least 16 °C such that it does not
permanently fall below the dew point. For units
with a condensate drip tray the water flow
temperature may be reduced to 15 °C.
Heat exchanger as 2-pipe system
Air-water systems with a 2-pipe heat exchanger
may be used for either heating or cooling. In
changeover mode it is possible to use all units
within a water circuit exclusively for cooling in
summer and exclusively for heating in winter.
Heat exchanger as 2-pipe system
Heat exchanger as 4-pipe system
Air-water systems with a 4-pipe heat exchanger
may be used for both heating and cooling.
Depending on the season, i.e. especially in spring
and autumn, it may be possible that an office has
to be heated in the morning and cooled in the
afternoon.
Heat exchanger as 4-pipe system
The maximum water-side operating pressure for
all heat exchangers is 6 bar.
The maximum water flow temperature (heating
circuit) for all heat exchangers is 75 °C; if flexible
hoses are used, the water flow temperature
should not exceed 55 °C. Units for other pressures
and temperatures are available on request.
