10 HEATING, VENTILATION AND AIR-CONDITIONING
SYSTEM (HVAC)
HVAC system provided in the vehicle enables occupants to
automatically/manually adjust air flow distribution pattern, air flow
rate, air intake mode and air temperature inside passenger
compartment. By appropriately adjusting the control knobs/
switches provided on the HVAC control panel, located on centre
console, occupant’s comfort can be ensured. HVAC system also
helps in defrosting and defogging/ de-misting the windshield and
windows.
Air flow direction can be further controlled by adjusting louvers of
air vents. An air filter is provided at the inlet of HVAC blower.
Engine coolant is utilized to heat the cabin air. For cooling the cabin
air, an air conditioning circuit based on the vapor compression
refrigeration cycle is used. The air conditioning system uses a
refrigerant along with a suitable lubricating oil. Although being non-
ozone depleting, the refrigerant is a greenhouse gas, hence once
allowed to escape in the atmosphere, it adversely affects the
environment by contributing to global warming/climate change.
Refrigerant used in system is a hazardous liquefied gas and is
under high pressure. The refrigerant is colorless and has
ethereal or faint sweetish odor. Exposure of refrigerant to skin
or eyes may cause irritation and frostbite. They can also cause
suffocation, dizziness and loss of concentration. When mixed
with compressed air or certain other refrigerants, it may form
flammable mixture. Never try to service HVAC system yourself
which would involve refrigerant handling.
Multiple vents are provided for distributing the air, being force-
circulated by HVAC blower, throughout the passenger
compartment.
To ensure sufficient air flow and hence adequate HVAC system
performance, air flow path should be kept free of obstructions.
Keep system’s air intake, located near plenum appliqué, free of
snow, leaves and other debris. Also keep the area in front of air
vents free of any obstruction inside the cabin.
