Heating and ventilation system, function
description (product alternative EHC)
Air vents
The heating and ventilation system (EHC) handles heating and venti-
lation. (The heating and ventilation system cannot perform cooling.)
The temperature in the cab is thermostat-controlled by control unit,
cab (D790-1). The cab temperature is controlled against set temper-
ature. The temperature can be set between 16 and 28
°
C. The unit
is operated with controls on the instrument panel.
The heating and ventilation system uses heat from the engine's cool-
ing system via a heating coil to warm the outside air. Outside air is
forced by the fan through the heating coil and on through channels
in the cab's interior, to be aimed at, e.g., the windshield (defroster)
or at the feet.
At the air inlet before the cab fan there is a filter that cleans the air
before it is forced into the machine.
The heating and ventilation system can:
•
add fresh air to the cab
•
clean the air from impurities
•
warm the air when it is cold
•
defrost the windows (defroster function)
