10 HEATING, VENTILATION AND AIR-CONDITIONING SYSTEM (HVAC)

10.1 Heating, Ventilation And Air-Conditioning System(HVAC)

The climate control system enables you to set the cabin at the desired comfortable

condition by controlling airflow, air intake and temperature control. The HVAC

system also helps in defrosting and defogging/de-misting the windshield and

windows.

Engine coolant is utilized to heat the cabin air. For cooling 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.

Multiple vents are provided for distributing the air, being force circulated by the

HVAC blower, throughout the passenger compartment. Various ducts supply air

from the HVAC unit to these vents having adjustable louvers.

Refrigerant used in the 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 the skin or eyes may cause irritation and frostbite. It

can also cause suffocation, dizziness and loss of concentration. When mixed

with compressed air or certain other refrigerants, it may form a flammable

mixture. Never try to service the HVAC system yourself which would involve

refrigerant handling.

To ensure sufficient air flow and hence adequate HVAC system performance,

the air flow path should be kept free of obstructions. Keep the system’s air

intake, located near the plenum appliqué, free of snow, leaves and other debris.

Also keep the area in front of the air vents free of any obstruction inside the

cabin.

There are two types of HVAC systems in your vehicle depending on the variant.

• Automatic Climate Controller

• Manual Air Conditioner
