PASSENGER’S COMPARTMENT HEATING AND VENTILATION SYSTEM
D
AILY
Purpose of the heating and ventilation system is to enhance
comfort inside the cab as regards the following parameters:
- temperature and relative humidity of outside air;
- temperature and relative humidity in the cab.
The system subjects the air to thermodynamic transformations
that affect its temperature, relative humidity and purity. This is
accomplished through the following functions:
- ventilation, i.e.: air taken from the outside (therefore with
temperature
and
humidity
of
the
surrounding
environment) is blown into the cab;
- air-conditioning, i.e.: air cooling and dehumidification, with
the possibility of heating it afterwards as preferred in order
to change temperature and humidity in the cab.
VENTILATION
Description
The ventilation function provides the intake of outside air,
purified from pollen and dust through a proper filter provided
for the purpose, or air recirculation inside the passenger’s
compartment.
The system consists of the following:
- heater / heater fan unit, set under the driver’s panel
covering that also includes a part of the heating and
ventilation system components.
- additional heater fan, adjustable at different speeds to
provide air flowing inside the passenger’s compartment
under whatever conditions of use.
- air ducts (fresh air intake and air recirculation).
- additional air heater, set at the base of the last rear seat
row.
